Hardware Architecture
SSD technology is available for use with most
operating systems and architectures. The SSD from Texas Memory Systems
for example is treated as a standard SCSI Fiber attached disk array.
In picking the architecture for this series of
tests it was decided to use the Intel based commodity type
architecture which is one of the fastest growing architectures today.
This would allow the tests to be recreated by anyone with even a
modest equipment budget. The server architecture used in the study
consisted of the following hardware:
2-Linux Servers each with:
-
2 - 1.88 GHz AMD 244 CPUs each with .75MB
I-cache, 1.5MB D-cache.
-
4 GB PC2700 DDR-33 Memory
-
1 PCI Fibre Channel 2X Card
-
1 PCI Lan Adapter
-
1 DVD ROM
-
2 SCSI Cards
In choosing the disk architecture it was felt that
using SCSI would best show the same level of hardware utilized by a
majority of sites. However, the failure of the SCSI array early in the
testing forced the switch to an ATA disk array that was ultimately the
architecture used. Therefore a disk array subsystem consisting of the
following was used:
-
1 SCSI Array (with a total of 2 - 36GB 10000 RPM
Disks)
-
1 ATA array (with a total of 7-200GB 7200 RPM
Disks)
-
1 Texas Memory System 64 Gigabyte SSD Array
The system used in the study is diagramed in
Figure 2.1.
Once the basic test plan (TPCH) and test
architecture were chosen the exact methodology to be utilized had to
be decided.
