HP servers are generally priced higher then Dell servers. Cost of the support is also higher, and quality is equal or lower. Reliability is approximately on the same level. Both Dell and Hp servers can work for approximately a decade although in enterprise env they are replaced in approx 5 years. Repairs are very rare. In my experience less then one in a hundred servers requires repair in the first five years on service. My feeling is that Dell servers produce less troubles if used with Suse then HP servers.
Dell servers that cost the same amount of money are faster (can be configured with better CPU, more/faster memory, faster/larger drives or combination thereof ) and use more cutting edge technology. See for example R710-DL380-database report. It was commissioned by Dell but is an interesting reading even in you take into account that who paid the piper.
We compared the database performance, hardware cost, and power utilization of two servers in similar common enterprise configurations. On our tests of Microsoft® SQL Server® 2008 database orders per minute (OPM), the Dell™ PowerEdge™ R710 delivered multiple advantages over the HP ProLiant DL380 G6.
They used the following configuration for PowerEdge R710 and ProLiant DL380 G6 respectively.
Processors Dual Intel Xeon® Processor E5540, 2.53 GHz
Memory 6 x 8GB PC3-8500R DDR3 6
Hard disks 8 x 73GB, 15KRPM, SAS
Power supplies 2 Dell A570P-00, 570w / 2 HP HSTNS-PL14, 460w
Disk controller Dell PERC 6/i Integrated RAID Controller, 256MB cache and BBWC / HP 410i Integrated Smart Array Controller, 256MB cache and BBWC
Operating system Windows Server® 2008 R2
- Database Microsoft SQL Server 2008
The main line of HP servers is Proliant inherited from Compaq acquisition. And they have some strange features: unlike Dell Drac, HP ILO needs additional license to be functional (remote console capability)
HP sells servers via resellers and that also complicates the picture as differences between configurations are often quite Byzantine. Even for exactly the same product price can differ 10% or more.
Troubleshooting can be helped by using Guided Troubleshooting which is somewhat similar to Microsoft approach but weaker. A sample (ILO Management Interface driver installation)
The iLO 3 Management Interface Driver enables system software such as SNMP Insight Agents to communicate with iLO 3.
The device drivers required to support iLO 3 are part of the PSP located on the SmartStart CD, Management CD, or on the HP website.
All the support drivers for your server and iLO 3 can be downloaded from the HP website:
Click here to download drivers at http://www.hp.com/servers/lights-out
To download the drivers:
Under iLO Support & Downloads
Click the iLO 3 Firmware
Select Operating system to proceed with the download.
Graphical logo hides several prompts and make administration more difficult. This is junk. disable it.
Adding drives is more or less safe operation. Preferable done with power off.
As for changing slots in which drives reside (even if the drive in question are not used and for example invisible in p401i BIOS interface) this is dangerious operation and you can lose all your data in one modent. Essntially what HP create is a parodiy on RAID not a real RAID. Overcompleity can byte here you in the most inopportunme moment. In you are unlacky you get the message
Messages in dmesg
cciss/c0d0: unknown partition table
and if you do not have a backup pay $5K or so for the restoration of perfectly good drives ;-)
So the rules here are:
this is a joke... rite? as long as meg is ceo their is no smart hp. she should try her hand at j.c. penny...... dumb as a rock
Who is trying to make meg less stupid.
Very Old Guy:
This is the poster girl for Corporate malfeasance with the BOD's paying millions of dollars in salaries and bonuses for bad acquisitions, no product development, C-suite hanky panky, corporate jets and expense accounts for inappropriate activities, constant reorganizations to cover up Corporate executives mistakes and lack of management ability demonstrated by constant cutting of the real workforce and punishing the "little people" for the errors of the top people. Sad comment, but typical of the modern American Corporation run by the "ME" people.
CEO's with multi million dollar bonuses seem to feel the best way to fix a company is to lay off 29,000 employees, perhaps they should start by cutting their own salaries and eliminate excutive bonuses and keep the people doing the real work around.
Re: #5--the days where HP employees were their "most valuable asset" are decades in the past; the only people that go to HP now are those looking for a cush cubicle job where they can get lost in the bureaucracy and byzantine org structure until they retire. As I've said elsewhere, the innovative areas of the company left a long time ago (e.g. Agilent); what's left is dross.
People forget that HP is really HP, DEC, and COMPAQ.. they've been cannibalizing decades of technology for the last decade; and now, they're out of left-overs. The execs have left behind a hollow shell of technology while making off with millions.

In this whitepaper titled, "Advantages of Dell PowerEdge 2950 Two Socket Servers over Hewlett-Packard Proliant DL 585 G2 Four Socket Servers for Virtualization", Dell attempts to showcase and compare the advantages of moving to a two socket Dell PowerEdge 2950 over the competitor four socket Proliant DL585 from HP.
Obviously, I read this whitepaper already knowing what the conclusion would be. Afterall, it was written by Dell. I knew the paper would be written based on fact, but the fact of the matter is had the conclusions drawn all been in favor of the HP over the Dell, I suspect that the test would have ended there without a paper being written up and distributed.
Nonetheless, this 16 page paper was a good read. For the most part, I liked the way the tests were developed and implemented.
The paper states:
There is a lot of debate these days around what is the optimal hosting platform for a virtualization deployment. Most of this debate is centered around the decision to deploy either 2 socket or 4 socket building blocks as the basis of the infrastructure. In order to illustrate the advantages of using two-socket servers for virtualization over four-socket servers, a test was conducted with VMware Infrastructure 3 on the Dell PowerEdge 2950 and the HP ProLiant DL585 G2.
The results of these tests show that three PowerEdge 2950 two-socket servers can provide up to 44% more performance, 57% more performance per watt and a 95% average advantage in price / performance than two HP ProLiant DL585 G2 four-socket servers. Another stumbling block to the adoption of one platform over another is the node count and the perceived complexity of managing more nodes in a virtualized farm. With the maturity of VMware's management stack in VMware Infrastructure 3 and in particular with Distributed Resource Scheduler, a new paradigm of pooled resource management is possible. Large farms of servers faced issues with complexity in the past, but the policy based management capabilities of VMware Infrastructure 3 greatly reduce these administrative issues. This then enables the further acceptance of farms of smaller, lower cost building blocks, such as the Dell PowerEdge 2950, as the preferred solution for virtualization deployments.
The Dell group concludes:
In terms of performance, power consumption, and costs the Dell PowerEdge 2950 two-socket, quad-core servers are a much better solution for virtualization than the HP Proliant DL 585 G2 four-socket dual-core servers. This is shown in the results of the testing with the two-socket virtualization solution from Dell providing up to 44% more performance, 57% more performance per watt and a 95% average advantage in price / performance than the HP four-socket solution.
To check out the entire white paper and how they came to this conclusion, download and read the following white paper.Published Sunday, January 14, 2007 10:58 AM by David Marshall
This page is the wiki home for a whitepaper that compares the price/performance of the Dell™ PowerEdge™ 2950 and HP Proliant DL385 G2 using Exchange 2007 as the workload. The complete paper with all details is linked and a summary / highlights of the paper are included directly on this page.
Discussion and questions about the paper can be written in the discussion threads area at the bottom of this page.
Exchange Server 2007 Performance Comparison of the Dell PowerEdge 2950 and HP Proliant DL385 G2 Servers -
While the Dell PowerEdge 2950 and the HP Proliant DL385 G2 are both two-socket x86-based servers, they are based on different processor-to-memory interconnect technologies. This difference can result in very different application performance when cost- and energy-efficient one-processor configurations are compared. For example, the Dell TechCenter lab ran tests simulating 4,000 e-mail users, and determined that running Exchange Server 2007 on the HP DL385 G2 server can cost up to 21 percent more than on the Dell PowerEdge 2950.
A PE2900 is NOT comparible to an HP ML350G4. It is way overkill for that. A PE1800 is more in line comparible to a Proliant ML350G4. The 2800 and now the 2900 is more comparible to a Proliant ML370G4 except the Dells give you a couple more drive bay slots.
I built an office system for an local surgeon around a PE1800 and it is working perfectly and is a great performer with excellent reliability. You can match the systems almost exactly feature for feature on a PE1800 with the HP ML350G4, and the PE 1800 will end up beating the HP's price too.
Do not skimp on the redundant power supply... I consider that to be an essential feature well worth the extra couple hundred bucks.
Also, I do not like internal tape drives. Spend the extra money and get an external LTO2 drive. The ability to power-cycle a stuck tape drive without touching the server itself is absolutely essential.
PS: Fill the machine with 4GB memory instead of only just 2GB. Memory is cheap these days, and if you intend to run both the Exchange Server and MS SQL that come with 2003SBS Premium edition, you'll need all the ram you can get and 4GB is the max supported by standard and SBS versions of Win2003 server.
