rx4640 vs. rx6600

[Patrick_82]

Hi All,

The rx6600 are so similar to rx4640. If my customer want to order new 64bit server for MS-SQL2005 64bit database. How should I choose?

Thanks!

I think the choice should be the next generation rx6600 Integrity server.

Technically there are differences between rx6600 and rx4640 if you refer the technical specifications of them at
http://h20341.www2.hp.com/integrity/cache/331424-0-0-225-121.html

There is a Performance brief and Benchmark result at

http://h20341.www2.hp.com/integrity/downloads/rx6600_TPC_080106%20WIN.pdf

where you would find that HP Integrity rx6600 Server achieves highest 4p/8c Microsoft® Windows®/SQL 2005 TPC-C performance result.

Hi Sameer,

Could you give me a linkage for rx4640 TCC-C on SQL Server?

Thanks!

Hi Patrick,

You would find the TPC result of rx4640 with SQL 2005 with a setup configuration at

While it is a bit of drift form the original topic, there is also a 4p/8c Linux TPC-C result for the rx6600 now.

The rx6600 has two more PCI-X slots than the rx4640. It can hold 16 internal SAS drives rather than two internal SCSI. IIRC it can hold more memory - 192 GB to 128GB IIRC.

There are PCI-X 2.0 slots in the rx6600 rather than PCI-X 1.0.

It is based on the "zx2" chipset rather than the "zx1" chipset and runs it faster, so there is more memory bandwidth.

The iLO is "newer" in the rx6600 and (IIRC) offers virtual media support. There is also support for the "dbprofile" command that folks familiar with the sx1000 "cell-based" systems may know about.

The rx6600 is also "taller" - it will consume a bit more space in a rack than the rx4640.

Patrick,

I will add my US$ 0.02.

Performance is a factor, so is price. The actual relevant factors are: price, performance, and budget.

The other important factor is workload. SQL Server 2005 is a helpful benchmark, but even more important is the question: Doing WHAT? Is the activity high? What is the expected workload?

It is also possible that a far smaller, newer generation system may be appropriate. My recommendations to clients always start with a sizing of the load, and an evaluation of the proposed hardware within that context.
