Solaris logical domains (Ldoms)
New version of T1 CPU supports heavy-weight (full hardware)
virtualization
It looks like Sun will soon became the first and only hardware vendor that competes
in all four virtualization weight categories:
-
Super-heavy-weight (Hardware domain-based; high-end servers only, essentially
"blades with common memory and I/O devices")
-
Heavy-weight (full hardware virtualization; Sun calls it "logical domains"
new hardware that supports the necessary CPU enhancements is expected the next
year; UltraSparc T1 "Niagara"-based servers will be the first -- the T2000 server
with this capabilities is expected to begin shipping in early 2007). It's unclear
if this enhancement will be backward compatible with existing T1-based servers.
-
Medium-weight (Para-virtualization based on Xen; only on X86 platform,
Sparc has separate implementation but may be two implementations will merge
in the future)
-
Light-weight virtualization (Zones or jails; currently they have very fuzzy
understanding of the limits of this technology and are extending it into medium-weight
(you want to run linux application: be my guest and create a special zone).
In comparison IBM mainly competes in just one category (heavy-weight virtualization).
Novell and Red Hat also in one category (Xen-based para-virtualization), Microsoft
in one category (heavy-weight virtualization), FreeBSD also in one category (light-weight
virtualization).

With LDoms, enterprises can run up to 32 virtual environments on a single server,
Larry Wake, group manager of Solaris OS Marketing, told ServerWatch. Each of
those partitions can then be divided further into Containers.
Up to 500 Containers can run on a single instance, though Wake admitted that
such a scenario would be unlikely in a real-world deployment. It does, however,
demonstrate the server's granularity.
Solaris' Container feature, which delivers essentially application-level
virtualization, is a common denominator, between its SPARC and UtraSPARC span
systems, Wake said.
Solaris 10 11/06, the next build of the operating system, will be released
at the end of November. The version will include new capabilities for Containers.
Admins will be able to clone a Container as well
as relocate it to another box, through a feature called Attach/Detach, Wake
said.
It wasn't just UltraSPARC T1 boxes that got a feature bump this week: x86
environments also received a virtual boost in the flurry of announcements.
In 2007, the systems vendor will offer full support for Xen functionality,
this time in the form of a Solaris 10-based Xen hypervisor. Enterprises will
be able to run concurrent Solaris 10, Linux and Microsoft Windows operating
systems as "guests" on a Solaris 10-based virtual machine, and will be able
to reap the benefits of Solaris 10, regardless of the operating system running.
... Enterprises looking for a more production-ready x86 virtualization option,
will need to be content with increased VMware support, however. Sun Fire x4600
and Sun Blade modular systems can now run VMware ESX 3.0.1.
Sun's remaining three enhancements, though equally touted, were more gravy
than meat. The Sun Fire X4000 Galaxy servers have been upgraded with Rev F Opteron,
AMD's next-gen Opteron processor and Solaris 10 Operating System.
Sun also announced Solution Customer Workshops, two-day sessions that
aim to match customers' needs to Sun technology and determine an appropriate
deployment plan. Sun estimates the value of these session as close to $10,000.
Presumably, the revenue the systems vendor stands to bring in from the sale
will exceed the $10,000 it invested in what is ostensibly a sales pitch.
Finally, Sun introduced the Life Cycle Services for Virtualization
program consulting — education and support services to help architect, implement
and manage customers' virtualization solutions.

October 18, 2006
Sun
announced a new virtualization function
for its
Sun Fire T1000 and
T2000 servers called Logical Domains
(LDOMs). LDOMs are partitions that enable
UltraSPARC-based servers to run multiple
instances of operating systems simultaneously,
whereby each instance can consume as little
as a single processing thread. LDOMs
complement Sun’s existing virtualization
functions, including
Dynamic Domains (i.e. hard partitions)
and
Solaris Containers (i.e.
OS virtualization). Although each of
these technologies provide similar capabilities
as LDOMs, they have varying levels of granularity
and different mechanisms for maintaining
isolation between OS instances.
Indeed, LDOMs
overcome some of the limitations of both
Dynamic Domains and Solaris Containers.
For example, LDOMs can be configured to
use a fraction of
CoolThreads processors, enabling far
more precise utilization of server resources
than Dynamic Domains, which require partitions
to be configured in multiples of four processors.
At the same time, LDOMs are more suited
for general-purpose workloads than Solaris
Containers, because they actually run their
own instance of an operating system. Users
may also have greater trust in the isolation
provided by the firmware-based
hypervisor in LDOMs than in the pure
software implementation of Solaris Containers
(see
design presentation - PDF) .
From a purely
functional standpoint, Sun's introduction
of LDOMs starts to close a competitive gap
with its UNIX competitors, including
HP and
IBM, each of which have UNIX virtualization
functions that required fewer compromises
than Sun’s earlier offerings. For T1000/T2000
users, LDOM’s ability to run multiple customized
copies of Solaris 10 may facilitate certain
types of workload consolidation more flexibly
than Solaris Containers, and their firmware-based
design may also offer a more reliable platform
for hosting Linux workloads compared to
the pure software-based implementations
of industry-standard virtualization products
such as
VMware or
Xen.
However, the
real value of LDOMs, hosting critical UNIX
applications with fluctuating workloads
more economically by configuring hosts for
average usage rather than over-provisioning
for spikes, may await implementation on
Sun’s next-generation high-end server systems
based on the
Advanced Product Line (APL) processor.
Neither Sun nor partner Fujitsu have promised
LDOMs on APL-based systems. But on these
platforms, which will have the ability to
support true
SMP implementations rather than the
thread-based multiprocessing of CoolThreads,
LDOMs will be suitable for efficiently scaling
typical UNIX workloads, rather than only
new applications with multithreaded designs.

Logical Domains
support was integrated into
Solaris Nevada
on May 16th. With Logical Domains (LDoms),
it would be possible to simultaneously run more
than one instance of Solaris on one box.
LDoms is supported only on
sun4v systems
(with
UltraSparc T1 processors). So, why is
only sun4v systems supported? Thats because
the UltraSparc T1 processor has Hypervisor support
built in. The firmware on sun4v systems also
support it. At this time the there are only
two sun4v models:
T1000 and
T2000.
LDoms support for
Solaris 10
is being integrated sometime in the next month.
After that both Solaris 10 and Solaris Nevada can
be run simultaneously on one system.
To use the LDoms features:
- Upgrade the firmware to the latest release.
- Upgrade the Nevada release to build 41 or
later (build of 17 May 2006 or later would also
do)
- Install the LDoms Manager (code name: Zeus)
which is bundled separately.
At the time of writing this, the firmware and the
LDoms manager is not available outside Sun.
I have some doubts here for which I did not find
any documentation:
- Does LDoms require at least one CPU per
domain or can one CPU run multiple OSes.
If it does require one CPU per domain, then
T1000 will not be able to run LDoms as it has
only one CPU?
- Is there is a limit on the number of domains
that can be run on a box if there is no requirement
of dedicated CPUs for a domain?
- When will the new firmware and LDoms manager
be available for all?
Well, I guess these would be answered soon.
Anyway, the possibilities of its usage, combined
with Zones, is numerous. I have been amazed
by some of our customers who use Solaris in ways
we did not even think is possible. With LDoms
and Zones, I'm sure it'll keep happening...
October 02, 2006. Many people may not remember, but when the T1 was
announced, it was stated it had a built-in hypervisor. Of course, now lots of
people have their T1000's and T2000's. It would appear that Sun will release
at some point a firmware upgrade to enable this feature to create Logical Domains
so you can carve up a T1 based server.
Each LDOM will have it's own OBP instance and act just like a normal Solaris
SPARC environment. The kicker is that this is all in firmware! This is not Zones
or Xen. I see this as a huge step in the right direction for Sun and can only
hope that it gets released soon. Here's an interesting
article on the subject that gives a good idea of what will be possible.
I especially like the slide on page 3 that shows CPU, Memory, and *I/O* being
virtualized with the next version of Solaris. I'm really interested in finding
out more about these features.
With these kinds of features in such a small package, it opens up a lot of
possibilities for virtualization and consolidation. With the ability to have
LDOM's running different versions of Solaris (10, 10u2, Solaris Express, etc)
and run zone's inside of those domains is really interesting. This could benefit
developers, engineers, and of course production environments. When the Niagara
II servers come out, the performance will be there to take this to the next
level. Of course, we'll all have to wait and see how this will unfold.
NOTE: If Sun needs a beta tester, I'm available:)
November 2, 2006
(The Unix Guardian)
... ... ...
Sun is picking up a theme from the
VMware
subsidiary of
EMC
, which last year announced a tool called the VMware
Player. With VMware Player, users can move their
virtual machines around and "play" them on any X86
or X64 machine. At the time, VMware conceived of
VMware Player as not just a tool for using VMs,
but also as a new means of distributing software--in
essence, a virtualized stack of software would be
put in a VMware format and distributed using VMware
Player, making this a virtual shrink wrapped box.
According to Ratcliffe, Sun is also
thinking virtual machines are a means of distributing
software, a kind of rapid deployment methodology
that, to its credit, Sun was talking about years
ago when it started up its N1 sales pitch to dot-com
customers. Ratcliffe says that Sun will be encouraging
customers to use virtualization tools to wrap and
distribute applications.
"A lot of the focus on virtualization
has been on running multiple operating systems on
a server," explains Ratcliffe. "We are working on
delivering pre-built stacks that are not just software
on a DVD, but a set of fully integrated, pre-tested,
and actually running software. We think this is
the most interesting part of virtualization, and
that it will become the standard way of deploying
software. It will let you go from a dead, cold system
to a running system in seconds."
Another thing that Sun is working
on is expanding its Solaris container technology
so it will be able to support earlier releases of
Solaris on a machine that is running the latest
release. Unfortunately for the 1.5 million or so
Sparc/Solaris boxes out there in the world (that's
my estimate), Sun cannot allow Solaris containers
on a Solaris 10 machines to support Solaris 9, 8,
7, or 2.6 applications. The guts of the Solaris
kernel in those versions of Sun's Unix are so different
that they cannot easily be made to share a kernel
and file system, which is how Solaris containers
work. But, the good news is that when the next version
of Solaris comes out--say it is called Solaris 11--this
version will be able to support Solaris 10 containers.
And so will Solaris 12, Solaris 13, and so on be
able to support Solaris 10 containers, too. In the
future, customers could upgrade their systems and
operating systems to a new version or release, but
leave their applications alone on prior releases,
not having to port and recertify them until they
see a need to.
On the virtual and logical machine
hypervisor front, Sun is also expecting some of
the key features of the Solaris 10 platform to give
it an edge over competing implementations of these
same technologies. "Today, the rush is to make sure
you have the right mix of hypervisor technology
to run multiple operating systems," says Ratcliffe.
"We think this is going to change. We think people
are going to want more functionality in their hypervisors."
So when Sun rolls out support for
the Xen hypervisor in the first half of 2007, expect
the company to make a big deal about the DTrace
system telemetry, its related predictive self-healing,
and user rights management features, and various
security features that are all part of Solaris 10
today. "The way we will implement Xen will bring
the benefits of Solaris 10 to operating systems
that do not have these features," says Ratcliffe.
"So rather than trying to make Solaris the operating
system of choice, Solaris becomes the strategic
choice of hypervisors."
For example, customers will be able
to, for example, run a DTrace on Windows applications
running on a Galaxy box inside Xen virtual machines,
and thereby be able to better tune them and perhaps
boost their performance or reduce the amount of
resources they consume.
Of course, a hypervisor is just a
new kind of single point of failure, and Sun as
well as its customers are well aware of this. So
Sun will be creating virtual machine methodologies
that will checkpoint and snapshot running VMs from
time to time, offering customers a chance for recovery.
But this capability of snapshotting
and moving whole stacks of software also presents
an interesting dilemma. "If you can checkpoint an
entire system and recreate it, is this a security
risk," asks Ratcliffe.
Sun has already developed data labeling
technologies in the Trusted Extensions to Solaris,
which are coming in the 11/06 update, that won't
allow people with the wrong clearances to see data
on a screen or move it to peripherals. Virtual machines
will need similar kinds of controls and tight security.
You won't have to hack an operating system any more,
but just steal the hypervisor and software stack
and hack it later at your convenience.
New sun4v platform
Sun Microsystems' comprehensive approach to
virtualization lets customers
apply the right technology in the right place at the right time. Today Sun is
expanding its offerings with new systems, technologies, services, and tools
that make it even easier for customers to simplify datacenters and maximize
resource use through virtualization:
A Comprehensive, Flexible Approach
For an enterprise to be as agile and efficient as possible, Sun understands
that virtualization must be available everywhere—at the server level, the network
level, the desktop, and in storage solutions. Unlike competitors that take a
one-size-fits-all approach, for years Sun has been providing a range of technology
choices that span the datacenter to address
customers' unique needs.
Sun's approach to virtualization provides both bottom-line and environmental
benefits. Energy-efficient systems from Sun that provide high compute density
in small footprints enable customers to reduce the amount of space required,
resulting in real estate, power, and cooling savings. Sun technologies also
allow customers to consolidate servers and applications onto fewer systems for
improved resource utilization, simplified IT management, and lower costs.
Sun's virtualization and consolidation capabilities help customers reduce
IT costs by as much as $2 million a year, achieve 99.99 percent availability,
deliver up to 80 percent system utilization, and simplify infrastructure management.
Key technologies include the following:
- Solaris 10 Operating
System: The most secure OS on the planet, the Solaris 10 Operating
System is the ultimate virtualization platform, allowing customers to easily
achieve higher utilization rates and consolidate servers without compromising
service levels, privacy, or security.
- Solaris
Containers: Provided for free in the Solaris 10 Operating System,
Solaris Containers let customers consolidate hundreds of applications onto
a single efficient Sun Fire system for increased resource utilization and
simpler management.
- Highly Efficient Servers:
Sun's extensive portfolio of UltraSPARC processor-based and x64-based servers
help companies lower costs by reducing energy, space, and cooling requirements.
- Virtualized
Storage Solutions: Unlike other vendors, Sun offers a wide range
of storage virtualization technologies that address SAN, NAS, file system,
and backup layers to provide organizations of all sizes with appropriate
solutions.
- Management
Tools: Sun provides a unique set of tools that let customers create
an efficient management architecture with high levels of automation for
managing systems more easily.
- Virtualization Resources:
Sun offers proven virtualization methodologies, return on investment (ROI),
and total cost of ownership (TCO) approaches as well as lifecycle services
to help customers architect, implement, and manage their virtual IT environment.
Sun's Latest Innovations
At the core of Sun's virtualization approach is making it easy for customers
to optimize their Web tier and business tier infrastructures. New innovations
include the following:
- New x64-based Servers: Sun's and AMD's partnership delivers the
fastest, most scalable, most energy-efficient, x64-based systems on the
market. Sun was the first vendor to ship systems with the Next-Generation
AMD Opteron processor with the recently announced
Sun Fire X2100 M2 server
and the Sun Fire X2200 M2
server. Today Sun is announcing availability of the
Sun Fire X4100 M2 server
and the Sun Fire X4200
M2 server, with the
Sun Fire X4600 M2 server soon to follow. Also featuring the Next-Generation
AMD Opteron processor, these servers are ideal platforms for virtualization,
delivering outstanding performance, energy efficiencies, and scalability.
NewEnergy Associates
was able to consolidate their datacenter consisting of 18 x86 servers, 24
CPUs, 22 power supplies, 44 hard drives, and 26 GB of RAM—which consumed
more than 14,000 watts of power—onto a single Sun Fire X4200 M2 server.
- Logical Domains Preview: Today Sun is previewing a new server
virtualization and partitioning technology called Logical Domains for servers
with the CoolThreads
technology in the
Sun Fire T1000
and Sun Fire T2000
servers. By deeply integrating with both the industry-leading multithreading
capability of the UltraSPARC T1 processor and the Solaris 10 OS, Logical
Domains technology helps to enable customers to run multiple operating systems
simultaneously. Up to 32 logical domains can be supported on a single CoolThreads
server, and each logical domain can run as an independent OS instance. Due
for release early next year, Logical Domains capability will complement
Solaris Containers to help customers better utilize server capacity and
increase efficiencies and ROI.
- VMware ESX Server 3.0.1 Certification: VMware ESX Server 3.0.1
software is now certified to provide virtualization capabilities on the
x64-based Sun Blade 8000
Modular System; certification for the Sun Fire X4600 M2 server is due
soon. The VMware software lets customers create virtual machines to consolidate
and easily manage several Solaris, Linux, and Windows servers on a single
physical system instead of multiple systems, enabling customers to reduce
complexity and achieve a server consolidation ratio of up to 20:1 or even
higher. Right now, customers can take advantage of a
VMware Starter Kit
that gives subscribers a 10 percent discount on select Sun Fire x64-based
servers.
Virtualization Made Simple
Sun is also offering a number of new and enhanced services, methodologies,
and tools to make datacenter virtualization as easy as possible for customers:
-
Sun Solution Customer Workshop: This new workshop lets customers
engage with Sun consultants in a two-day collaborative session designed
to assess current customer business requirements, match these requirements
to technology requirements, provide a high-level TCO analysis and long-term
savings estimate, and determine actionable next steps. For a limited time,
customers can receive this service worth an estimated $10,000 at no cost.
-
Lifecycle Services for Virtualization: The Sun Architecture Service
and Sun Implementation Service help customers design and implement solutions
to extract maximum value from their virtualization investments.
-
Online Virtualization Learning Center: This Sun learning center
provides quick access to multimedia presentations, how-to guides, and demonstrations
for learning more about virtualization's datacenter benefits.
- Upgrade Allowance
Programs: Sun programs let customers trade in existing equipment
when building new virtualization solutions for significant discounts.
- Virtualization Resources:
Sun BluePrints, technical white papers, and valuable tools help customers
learn even more about virtualization implementations and calculate potential
savings.
By giving customers all the innovations needed to truly optimize their datacenters,
Sun's comprehensive virtualization approach lets businesses reap cost savings
today and more easily take advantage of opportunities tomorrow. Continued innovation
will ensure that Sun remains on the cutting edge of virtualization advancements
well into the future.

January 25, 2006, SAN FRANCISCO--Sun Microsystems later
this year will introduce virtualization technology to let its newest Sparc-based
servers run multiple operating systems simultaneously, thus catching up to a
feature already built into Unix machines from rivals IBM and Hewlett-Packard.
The technology, called logical domains, will be added to Sun's two
UltraSparc T1 "Niagara"-based servers--the T2000 server Sun began shipping
in December and the T1000 it plans to begin shipping in February, said David
Yen, executive vice president of Sun's Scalable Systems Group.
"This calendar year, on the T2000 and T1000, we will introduce our first
generation of virtualization to bring people beyond the container technology
Solaris 10 already offers," Yen said in a meeting with reporters and analysts
at Sun's offices here. "We have real customers demanding it," particularly in
the financial services industry, he added in a later interview.
Running multiple operating systems is useful for making a single computer
more efficient and is a major trend in the server market today. Building the
feature into Sun servers will address a key piece that's been missing from the
Santa Clara, Calif.-based company's mainstay product line.
Sun is feverishly working to restore its server group's fortunes. The company's
server shipments dropped 6 percent in its most recent quarter.
To run multiple operating systems on a Sparc server now, Sun has offered
only hardware partitions, a relatively inflexible method that lets higher-end
Unix servers be subdivided into four-processor partitions. At the other end
of the spectrum, a Solaris 10 operating system feature called containers lets
a single instance of the operating system appear to be several--but that technology
offers less protective isolation for different applications.
"This is something that Sun has needed to do for a long time in order to
get parity with HP and IBM," said Gabrial Consulting analyst Dan Olds. The next
step will be to make sure the feature fits into higher-level management tools,
he said. "They need to show customers that their systems have the ability to
manage IT resources according to business need--without human intervention--in
order to catch up to HP and IBM."
The movement to run multiple operating systems on a single server has been
maturing long enough that even comparatively lowly x86 servers have the ability
through use of VMware's virtual machine software. And an open-source software
project called
Xen is under way with similar features.
Xen is the future, Yen said. Although the company developed its own logical
domain software, Sun eventually expects it will become one with Xen.
"Eventually we expect Xen will get industrywide acceptance, and we'd like
to be part of it. Some time, probably in the second half of 2007, we will merge,"
Yen said.
John Fowler, who as head of Sun's Network Systems Group is Yen's counterpart,
said Xen for his x86 server group is gradually maturing.
"A lot depends on Xen 3.0 getting done. This is not up to marketing intent
but to the engineering gods," Fowler said. "This kind of software is pretty
hard. There's rocket science in elements of the stack and in making sure you
get it right and it doesn't fall over."
Xen and operating system companies "have talked optimistically about this
spring" for Xen 3.0, but "I think it'll take a little bit longer. I think this
year is very possible," Fowler said.
Firming up firmware
The logical domain feature will be available in an update to the T1000 and T2000
firmware, software that runs at a lower level than the operating system, Yen
said. The update won't degrade performance or require customers to recertify
their software, he added.
That firmware has another important function, Yen said. It provides a new
foundation for Solaris. As Sun worked to move Solaris to x86 chips such
as Advanced Micro Devices' Opteron, the company realized it needed a more flexible
connection between the operating system and the chip it's using. The firmware
provides that new interface, he said.
"All Solaris has to do is talk to the API (application
programming interface) presented by that layer," he said.
The layer also will ease development for the
programmers who work on Linux for Sparc-based computers, Yen said. "To facilitate
Linux porting...we will publish the API for the internal firmware," he said.
Sun will
release the underlying hardware description of the UltraSparc T1 by the
end of March, he reiterated. And Sun will also release its UltraSparc 2005 specifications,
which detail extra features Sun's chips have that aren't in the Sparc V9 standard
promulgated by the Sparc International organization.
Sun has shipped thousands of T2000 systems so far, Yen said. Most customers
are buying just one or two for evaluation purposes, but a global telecommunications
company placed an order on Tuesday for 75 of the machines, he said.
Yen said that late this quarter or early next quarter, T2000 and T1000 customers
will get a new option: an expansion device that increases the number of input-output
slots that are available.
