Database in Memory

Customers running this emerging application need to have very large datasets in memory.

Loading or refreshing these from disks becomes a time-critical effort. Large Linux™

clusters are an example of this type of computing complex, where loading as much as

12TB of memory from disk storage in less than seven minutes can be the requirement. 4

Gb/s storage systems can be used effectively for this demanding application as data can

be loaded from the storage to the server in as little as half the time compared to 2 Gb/s

Fibre Channel.

Recovery is more important than backup, and the time it takes to recover is becoming

more important every day. Systems based on 4 Gb/s Fibre Channel technology are

designed to deliver the high bandwidth performance required to enable short recovery

time and high productivity.

Data warehousing presents a unique challenge for storage systems because both high

bandwidth and high random I/O performance are required for effective solutions. The

balanced performance of systems based on 4 Gb/s Fibre Channel technology helps

address this challenge. They offer high levels of performance in both the bandwidth and

IOPS dimensions.
