* HP EVA 4400 Architecture is based on an clustered controller/sever/switch architecture. Performance is based on a PowerPC CPU and a switch connected 4 Gb/s Fibre Channel back-end. The HP EVA is really a collection of components interconnected within a rack and presented as a modular disk subsystem. The EVA most significant strength with the product is the ease of administration and provisioning provided by the VRAID disk administration. The down side of the VRAID architecture is that the disk pools are completely balanced with no regard for production versus test. Also the VRAID architecture spreads the load of reconfiguration and recovery across all disks in the Disk Group. Unlike traditional arrays, the EVA does not reserve physical disks. The reconstruction space is distributed across all disks in the disk group so that all disks remain available for application use. This is called distributed sparing. HP’s best practice document recommends setting up multiple Disk Groups (High Performance and medium performance groups) The EVA4100/4400/6100/8100 support iSCSI attach configurations using the HP MPX100. HP StorageWorks Clustered Gateway The HP StorageWorks Clustered Gateway delivers superior file serving performance and scalability for enterprise customers on an industry standard platform. Fully symmetrical cluster architecture assures high availability with complete data and cache coherency and failover. With scalability up to 16 TB for the Linux version or 8 TB for the Windows Storage Server 2003 version per file system; this will meet the most demanding Enterprise file serving needs. This solution delivers price and performance. We selected the FibreSpy root switches for the HP EVA family because it offers our customers superior performance, flexibility and reliability. By working with Emulex to integrate FibreSpy into our EVA family, HP is again showing its commitment to deliver the industry’s leading storage systems.Kyle Fitze * Presenter No
