Appendix A - System Configurations For The Performance Experiment - Hitachi Lighting 9900 Series Architecture Manual

System Configurations for
the Performance Experiment
Configurations of the HP and Sun Servers and Configurations of the
Lightning 9960 ™ Switched Architecture to a Shared-bus Architecture like
most competitive products for the Performance Experiment
In the performance test discussed in Chapter 8, comparing each application resided on
its own array groups. The only resource shared by the application is the storage controller
(cache, paths, etc.), and two ACP pairs (there are four ACP pairs total). The comparison
is between the Hitachi Freedom Storage
architectures, and the Lightning
The application workloads consist of two very different types of database environments
– an On-line Transaction Processing (OLTP) system and a Decision Support System (DSS).
The OLTP workload runs on a HP platform consisting of the following configuration for
both storage arrays:
• HP /9000-K460 dual processor 180MHz, 768MB RAM, 4 Fibre Channel HBAs
®
(FC-AL topology) direct connect to either the Freedom 7700E or the Lightning
9900 Series system.
™
• HP-UX 11.00.
®
• Oracle Database Server 8.0.4 with 50MB of SGA (in order to drive I/Os to the
®
storage arrays), 2KB database block size.
• OLTP database with simulated user drivers (similar to the TPC-C benchmark).
• 7700E and Lightning 9960
(FC-AL topology) ports, 2 ACP pairs, 6GB 12,030RPM drives,
RAID 5 formatted. The following are differences between the 7700E and
Lightning 9960

• 7700E used OPEN-K volumes and a total of 48 disk drives (12 array groups
total).

tables occurred because of this), 40 disk drives (10 array groups total), and
18GB 10,025RPM drives.
The DSS workload runs on a Sun platform and consists of the following configuration:
• 2 Sun E3000 dual processor 250MHz, 512MB RAM each, 2 32-bit JNI HBAs
(point-to-point fabric topology) Fibre Channel switch (Ancor

• Oracle Parallel Server 8.0.5, 16KB database block size (256KB I/O block size).
®
• DSS database with one large table – 600037899 rows at 112 bytes each.
Performing full parallel table scans with multiple instances.
• 7700E and Lightning 9960

RAID-5+ formatted – 64 disks total (16 array groups). The following are
