core i3 compatibility with SAS drives

August 11, 2011 at 13:50:25
Specs: Windows Xp
I have to choose between following two servers. The specs are as below:

My preference:
x3200 M3, Core 2C i3-540 73W 3.06GHz/1333MHz/4MB, SS 3.5in SATA, DVD-ROM, 401W p/s, Tower
2GB (1x2GB, 2Rx8, 1.5V) PC3-10600 ECC DDR3 1333Mhz LP UDIMM, Qty 2
ServeRAID M5015 SAS/SATA Controller
IBM 300GB 3.5in SL HS 15K 6Gbps SAS HDD, Qty. 4 nos.
Line cord - 2.8m, 10A/250V, C13 to BS 1363/A (UK)

Vendor suggest after getting payment saying following is better:
x3400 M3, Xeon 2C E5503 80W 2.0GHz/800MHz/4MB, 1x2GB, O/Bay HS 3.5in SATA/SAS, SR BR10il, DVD-ROM, 670W p/s, Tower
2GB (1x2GB, 1Rx8, 1.5V) PC3-10600 CL9 ECC DDR3 1333MHz LP RDIMM

The vendor seems to give misleading statements and it was hinted out probably Core i 3 processor and RAID controller doesn't support SAS drives and instead I could only get what I want with SATA drives only? Need to confirm if this is the real issue or if the vendor is really true about his offering. Tried much to get the direct contact with IBM people but there are lots of covers and bias in favour of their partner world. I am really confused can any body help.

The application I need to run on this machine is designed on ORACLE 9i, using embedded database; can't use cores above 2 due to license fee besides preferred OS should be Windows Xp.

The processor has nothing to do with the type of drive.

Well thanks about the comment, is it because of the RAID controller then? Because one IBM rep hinted out perhaps they need to replace the current RAID controller with a specialized RAID controller to support SAS. I could have accepted the Xeon server X3400 too but this system in its standard specs/data sheet doesn't seem to support Windows Xp as OS whereas there is a big difference of license cost between Windows Server 2003, R2 St. Edition and Xp

You are using very generic terms, to be sure, I'd need to at least know the exact make and model of this sas device or more on how you plan to attach them.

In the most simple sense, a drive is connected to some controller. You can't attach a sata drive to a scsi card for example. Now as to what kind of array you have I can't tell. You could be talking about an external sas but in any case you need a few things.

You will have to look up if those are supported in XP. Sadly XP is getting hard to support. It never did have much support for enterprise level stuff either. If you need a server software then you need it otherwise there might be support for the devices in Windows 7 too You don't need cal's for simple file servers only for domain clients. Not sure I'd even consider W2003 either since W2008 is out.

You may consider a linux distro also but that would more depend on your uses.

See also 2x.com for ideas.

For any kind of common soho use I'd think the core i3 may be sort of lacking. Your best performance per dollar to me is in a server grade nic. They do make atom based servers that seem to suite some needs.

XP can run on two real processors so a dual processors with dual cores is still good to go.
