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.
