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™ 7700E, representing all shared bus-based architectures, and the Lightning™ 9960 system, representing a switched fabric architecture.

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™ system with 1GB cache, 4 Fibre Channel (FC-AL topology) ports, 2 ACP pairs, 6GB 12,030RPM drives,

RAID 5 formatted. The following are differences between the 7700E and Lightning 9960™ system for the OLTP workload;

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

•Lightning 9960™ system used OPEN-9 volumes (some doubling up of 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® MKII 16 ports) connected each.

•Sun® Cluster 2.1.

•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™ system with 1GB cache, 4 Fibre Channel (point-to-point fabric topology) ports, 4 ACP pairs, 6GB 12,030RPM drives, RAID-5+ formatted – 64 disks total (16 array groups). The following are

With Hitachi LUN Manager, open systems Logical Units LUNs can be defined, configured, and maintained. There is no more waiting for the hardware vendor to come and make configuration changes. Hitachi LUN Manager includes an easy-to-use, GUI-basedinterface that allows the easy definition of paths for LUNs, the reconfiguration of LUN-to-portassignments, or the viewing of the Lightning 9900 remote service information messages. Because the Hitachi LUN Manager can assign multiple paths to a single LUN, support of alternate path failover, path load balancing, and clustered systems is possible. Running on a standard Windows-basedPC connected to the storage subsystems by a dedicated LAN, Hitachi LUN Manager can support up to eight Lightning 9900 systems Hitachi Data Systems Hitachi CruiseControlStorage Maximizer Hitachi SANtinelHitachi Data Systems Data Protection Services Professional Services and SupportProfessional Services Overview Cost of Risk Analysis methodology CORA Hitachi NanoCopy Implementation Service Data Protection Services Lab Remote Copy Assessment and Implementation Service Hitachi Data SystemsOn-lineData Migration Service Professional Services and SupportContinuous Availability Service SAN servicesSoftware Portfolio Review and Analysis Service Hitachi Data SystemsSystem Configurations for the Performance ExperimentHitachi Data Systems The 7700E used all 6GB drives100BaseT Glossary of Terms10BaseT ACP pairBack end Hitachi Data SystemsAvailability Business Continuity Planning BCPCache GlossaryCARB CHIPControl Frame Hitachi Data SystemsConsistency Groups CORA Cost of Risk AnalysisData Duplication Disaster RecoveryGlossary Data MigrationElectronic vaulting Hitachi Data SystemsEBCDIC ESA/390Fast Ethernet GlossaryFailover Fast writeFICON File BackupHitachi Data Systems Front EndHDmS Hitachi FlashAccessGlossary Hitachi CruiseControlHitachi InstantSplit Hitachi Multiplatform Backup/RestoreHitachi Data Systems Hitachi LUN ManagerHitachi Resource Manager Hitachi Rapid RecoveryGlossary Hitachi SANtinelHYPERtape Hitachi Data SystemsHXRC Hitachi Extended Remote Copy JavaLightning 9900 Series Logical VolumeGlossary Logical UnitMIPS Hitachi Data SystemsMBCP Meta-dataMTTR GlossaryMTBF NanoCopyOpen system Hitachi Data SystemsOn-linesystem Operating SystemRAID Recovery TimeGlossary RAID ControllersSCSI SwitchHitachi Data Systems SnapshotGlossary Virtual Logical Volume Image ManagerVolume SynchronousWarm site Hitachi Data SystemsWorkload Asia Headquarters Hitachi Data Systems Worldwide OfficesCorporate Headquarters Australia/New Zealand Headquarters
