Servers for Sale!

by dave on October 20, 2008


From time to time, I like to clean out some of the “older” hardware lying around the lab.  So, for your perusal today, I’ve got 3 servers that are going to be up for grabs (complete with the requisite Paypal/GoogleCheckout links).  Click on through to see the descriptions and pricing.

Note:  Each of these servers has run VMWare ESX 3.5 (up to Update 2) without issue.  The two AMD boxes, in particular, have at least 6 months of uptime between them except for minor hardware upgrades done along the way.  VERY impressive boxes to use with ESX.

Part of the beauty of ESX 3.x from a hardware support standpoint was the addition of SATA as a viable install media for the hypervisor and service console.  However, opening up support for SATA also included a few hiccups along the way, most related to the SATA controllers officially supported by VMware.  For folks like myself who spent a lot of time with AMD-based platforms, the only real choices for SATA controllers (onboard the motherboard, not discrete) were offerings from Broadcom and nVidia.  This post will highlight how to configure your ESX 3.x host to use nVidia SATA controllers.

Note: This information is available within the VMware user community as well.  I am indebted to the person(s) in that community who provided this information, albeit in a slightly less “visual” way.

Snoop Filters and the Tyan S5397

by dave on September 26, 2008


Just to add to the ever-growing information data base on the excellent Tyan S5397.

If you seem to be having problems with reported memory bandwidth in your favourite worthless synthetic benchmark or reality-based simulation workload, try disabling the Snoop Filter in the bios.

Remember, the Intel Xeon processors use a different set of prefetch schedulers than standard “consumer” level parts, so, this can also affect workload.
