    New SBS 2011 server w/ RST has painfully slow drives

    Chuck Lavin

      Hi --

       

      I have a server built on a Supermicro X7DB8 board (Intel 5000P chipset) with two 3-Ghz Xeon processors and 16 GB of RAM. It has two RAID1 sets using two pairs of identical Seagate drives, running under IRST 10.1.0.1008. It is running Windows Small Business Server 2011 SP1. This server is painfully slow. The simplest requests take inordinately long times to resolve. I have looked high and low for the reason for this, and the problem seems to come down to really, REALLY slow drives.

       

      This same server had been running SBS 2003 on 2 GB of RAM and two different RAID1 sets (also Seagates) on an earlier rev of IRST, and the machine hummed along beautifully. When the SBS 2003 was decommissioned, I rebuilt this machine with new RAM and four new, faster hard drives and installed SBS 2011 clean. So far, about the only thing the machine is running is the server base and SBS software set, albeit with all the updates from Microsoft. It currently has only one user in AD and doesn't even have a PC attached to the domain yet. I don't even have an antivirus program running on it. But response times on this machine are dismal.

       

      A Passmark Performance Test on the two RAID volumes gives me consistently low results:

       

      Drive C: (SYSVOL)

      Sequential read: 34.4 MB/sec

      Sequential write: 41.0 MB/sec

      Random seek+RW: 8.6 MB/sec

       

      Drive D: (DATAVOL)

      Sequential read: 70.2 MB/sec

      Sequential write: 45.4 MB/sec

      Random seek+RW: 11.2 MB/sec

       

      The results never vary much from the numbers above. These are from SATA-3 drives.

       

      The IRST System Report follows. As far as I know, version 10.1.0.1008 is the latest version of RST that supports the ESB2 controller. The server has the latest available BIOS. I also installed the latest Intel chipset INF files.

       

      What could be causing this horrible disk response?

       

      Thanks,

      CL
