Established in 1962, Purdue University's Krannert School of Management offers instruction at the undergraduate, master's, and doctoral levels. As part of an upgrade of its IT infrastructure, Krannert recently implemented an end-to-end SAS storage area network (SAN) based on LSI® 6Gb/s SATA+SAS host bus adapters (HBAs) and industry-first 6Gb/s SAS switch.
The LSI SAS SAN solution has helped the school to optimize storage performance and utilization behind its expanded virtual server capacity; deliver an order of magnitude more storage bandwidth; and improve fault tolerance -- all at a fraction of the cost of implementing a new Fibre Channel or iSCSI SAN. The SAS SAN solution also provides the flexibility and scalability to allow for future growth while improving the protection of student, faculty and administrative data vital to the school’s daily operations.
At the heart of the Management School’s SAS-based SAN, which was built by LSI channel reseller partner, Area Data Systems, are two ½ wide, 1U 16-port LSI SAS6160 SAS switches. Each of the SAS6160’s 16 4-lane SAS ports delivers bandwidth of 24Gb/s per port for up to 384Gb/s aggregated bandwidth per switch. The school’s servers utilize two LSI 6Gb/s SATA+SAS HBAs with two connections per HBA, for a total of 96Gb/s of throughput to the SAN.
While improved performance was a key requirement, data availability, protection and recoverability were the school’s highest priorities. With active students on four continents, assignments, faculty research and administrative records must all be online with 24x7 accessibility. LSI SAS6160 switches provide multiple, redundant data paths to its RAID-protected external storage pool of almost 35TB. The SAS6160 switches also improve IT efficiency by maximizing storage resource utilization while eliminating islands of storage, resulting in significantly reduced energy use and physical footprint.
