The StorageWorks D2200sb Storage Blade delivers direct attached storage for c-Class servers, with support for up to twelve hot-plug small form factor (SFF) SAS hard disk drives. The enclosure backplane provides a PCI Express connection to the adjacent c-Class server blade and enables high performance storage access without any additional cables. The D2200sb features the onboard Smart Array P410i controller with 1 GB flash-backed write cache, for increased performance and data protection. Use the HP P4000 Virtual SAN Appliance Software (VSA) to turn the D2200sb into an iSCSI SAN for use by all severs in the enclosure and any server on the network. VSA includes remote replication capabilities, thin provisioning, and snapshot. Combine the D2200sb with the HP StorageWorks X1800sb Network Storage Blade to enable file serving iSCSI shared storage inside the BladeSystem enclosure.
