IBM TotalStorage Enterprise Storage Server FlashCopy Function with the VMware ESX 2.5 Server

Short Description
Today, many businesses have become increasingly dependent on data storage and require a high level of availability to support 24 hours a day, seven days a week (24×7) operation. A lengthy outage could lead to significant financial losses, loss of credibility with customers, and possibly even a total failure of a business. Therefore, the ability to support high availability for the major applications is more often than not a necessity for business survival. A key component of a highly available system is the storage subsystem. It is essential that high availability of data is supported, and that downtime for data backup and software maintenance is minimized or more preferably eliminated.
