- Fermi Linux Server Vendor Qualification--Closeout Report

## Technical evaluation of 1U dual Xeon units is complete
18 vendors identified as technically qualified
Next step is price/performance bid.  Requisition for 48 nodes in division approval now.
Will weed down vendors to five.

## We made contact with 45 vendors in all.
29 vendors attended Jan 28. info meeting
24 vendors submitted acceptable configuration on Feb. 4
21 vendors submitted acceptable benchmarks and were cleared to ship unit on Mar. 4—all got it here by Mar 11.

## Software check
Most points evaluated from benchmark results vendors submitted by E-mail before units arrived.
Hardware check:
All units opened, checked for quality construction and correct configuration.   Pictures taken of all
Electrical and thermal measurements
One vendor disqualified for shoddy construction and bad service explanation of why it was that way.

## Electric current measured with ammeter at startup, idle, and full CPU load.
Current draw ranges: 2.4GHz, 1.6-2.0A, 2.8 GHz, 1.8-2.3A, 3.06GHz, 2.1-2.35A
Likely that with purchase of 2.8 or 3.06GHz machines we can only have seven machines per circuit, not eight as in the past.
Those with higher current draw also tend to have more fans and be better internally cooled.
Bright side—This current similar to 750MHz machines bought 3 years ago, 2.5x the performance for the same current.
Table in the final report.

## Measured T from front to back of unit for all.
Used internal temperature probes on each unique type of case.
All units in evaluation much cooler than the 1U units bought in FY2002.  
Due to better thermal characteristics of Intel chip and many more added internal fans and blowers.
Still analyzing the data we took but confident that all units are acceptable.

## 3 CPU speeds measured, 2.4, 2.8, 3.06 GHZ,
1000 FermiCycles=PIII 1 GHz.
Approximate performance, 1779,2041,2223 Fermi Cycles respectively. 
400MHZ vs 533 MHz front side bus is 2.5% effect for farms software, much bigger for QCD.
AMD MP2200+ --1771 Fermi Cycles
Performance is projected to faster clock speeds in anticipation that some vendors will bid faster chips.

## All had at least one hardware call and one software call.
One vendor disqualified because primary service provider listed wouldn’t show up
One vendor disqualified due to excessive downtime of machine.

## Rackmount proposals evaluated for all
Most still using conventional front-to-back cooling, standard rack.
Several feature tool-free rails

## 18 technically qualified vendors—in alphabetical order
Ace, Angstrom, APPRO, ASA, Aspen, Atipa, Concentric, Dell, HP, IBM, Koi, Penguin, Promicro, PSSC, Rackable, Racksaver, Richardson, Western Scientific
Price/performance bid will weed them down to five.
All technically qualified vendors will be remembered if some of the top five fail to perform, or if special capabilities, such as AMD, desktops, or blades, are needed.
Requisition for 48 nodes is at division (32 farms, 16 FNALU).
21 vendors is too many to bring in, will be more discriminating next time.
