[Oct 28, 2011] Notice: ProLiant Servers - HP Service Pack for ProLiant 2011.09.0 Is Available Beginning on October 5, 2011 (c03065190)

Products: HP ProLiant DL Servers, HP ProLiant ML Servers, HP ProLiant BL Server Blades, HP ProLiant SL Servers Description: Notice: ProLiant Servers - HP Service Pack for ProLiant 2011.09.0 Is Available Beginning on October 5, 2011

[Mar 23, 2010] Take a look at what is being spec'ed

CPU should be with 1333MHz bus:

Intel® Xeon® Processor X5570 (2.93 GHz,8MB L3 Cache, 95 Watts, DDR3-1333, HT Turbo 2/2/3/3) 507674-L21
Intel® Xeon® Processor X5560 (2.80 GHz, 8MB L3 Cache, 95 Watts, DDR3-1333, HT Turbo 2/2/3/3) 507676-L21
Intel® Xeon® Processor X5550 (2.66 GHz, 8MB L3 Cache, 95 Watts, DDR3-1333, HT Turbo 2/2/3/3) 505878-L21

> Disks are 10K rather than 15K ... does it matter?

Yes, difference is around 10-15%.

> Can you determine the memory type?

No. Looks like they overspecified memory. If memory is DDR3 1333 MHz the size should be multiple of 3 -- 6G or 12 G

recomendations for the future for servers where i/o is important.

1. For server with high i/o load it is better to use HP Smart Array P410i/512 MB BBWC Controller (RAID 0/1/1+0/5/5+0)
Controller with no memory might be a bottleneck (see,1702.html). I think controller memory is installable.

2. 15K RPM drives give ~ 20% better I/O throughput then 10K RPM drives.

3. In server configuration CPU should be matched with memory. I would not go lower then L5570 for mail server. We are buying RISK servers for multiples of Intel server price so we should be too cheap with important Intel servers. In case of budget CPUs with 800MHz memory bus it does not much sense to use DDR3-800 CPU with 1333MHz memory like often is the case. Cheaper DDR3-800 memory should be used.

Intel® Xeon® Processor X5570 (2.93 GHz,8MB L3 Cache, 95 Watts, DDR3-1333, HT Turbo 2/2/3/3) 507674-L21
Intel® Xeon® Processor X5560 (2.80 GHz, 8MB L3 Cache, 95 Watts, DDR3-1333, HT Turbo 2/2/3/3) 507676-L21
Intel® Xeon® Processor X5550 (2.66 GHz, 8MB L3 Cache, 95 Watts, DDR3-1333, HT Turbo 2/2/3/3) 505878-L21
Intel® Xeon® Processor E5540 (2.53 GHz, 8MB L3 Cache, 80 Watts, DDR3-1066, HT Turbo 1/1/2/2) 505880-L21
Intel® Xeon® Processor E5530 (2.40 GHz, 8MB L3 Cache, 80 Watts, DDR3-1066, HT Turbo 1/1/2/2) 505882-L21
Intel® Xeon® Processor E5520 (2.26 GHz, 8MB L3 Cache, 80 Watts, DDR3-1066, HT Turbo 1/1/2/2) 507680-L21
Intel® Xeon® Processor L5520 (2.26 GHz, 8MB L3 Cache, 60 Watts, DDR3-1066, HT Turbo 1/1/2/2) 505884-L21
Intel® Xeon® Processor L5506 (2.13 GHz, 4MB L3 Cache, 60 Watts, DDR3-800) 507678-L21
Intel® Xeon® Processor E5506 (2.13 GHz, 4MB L3 Cache, 80 Watts, DDR3-800) 505886-L21
Intel® Xeon® Processor E5504 (2.00 GHz, 4MB L3 Cache, 80 Watts, DDR3-800) 507682-L21

4. I suspect that for optimal use of three channels of Intel 5520 chipset with DDR3 memory the number of RAM modules should be multiple of three.

That's how many higher end retail computers are configured. That should be verified with HP.
