Executive Summary Hewlett-Packard (“HP”) commissioned VeriTest, the testing service of Lionbridge Technologies, Inc., to compare features and functionality between the HP StorageWorks P4500 SAS SAN Solutions and the Dell PS6000XV storage arrays. The 3-node HP P4500 SAN, a Virtualization SAN with an HP P4500 expansion node, has a current list price of $96,600.00. The 2-node Dell PS6000XV currently has a list price of $110,000. The goal of this study was to evaluate these devices in terms of high availability, capacity utilization under various common usage scenarios, and ease of upgrading the storage solution to meet future storage requirements.
Both HP and Dell provide a scalable iSCSI based solution, each claiming the following benefits: scalability, flexibility, cost effectiveness and high availability. Lionbridge developed a test methodology that compared these benefits between the two vendors to help end users better understand the real-world differences experienced with each product under test. Both solutions are based on a scale-out technology, combining multiple nodes into a cluster and thus presenting a common storage pool. For these comparable prices, the configurations below are what were available for each product. Therefore, the hardware configurations were not identical with regard to number of nodes and disk spindles.
The HP P4500 SAN configuration consisted of a three (3) node cluster running SAN/iQ version 8.1.00.0047.0 with RAID5, and 2-way replication. Each node contained 12 450GB 15K RPM SAS drives with a total raw capacity of 16.2TB.
