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.
Quick Recovery
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
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.
