BladeCenter storage

This paper describes the available storage options for the IBM eServer™ BladeCenter® system—local hard disk drives on each processor blade, network-attached storage accessed over Ethernet, and storage area network (SAN)-attached storage accessed over Fibre Channel—highlighting where each provides a compelling or unique storage solution. The basic selection criteria are presented, focusing on the most significant attributes of each option. Additional information is provided for emerging technologies, iSCSI (SAN-attached storage accessed over Ethernet) and InfiniBand®, and the technologies and attributes that have unique importance in a blade-server environment.
