ABSTRACT
Establishing a performance service level agreement and a knowledge base will generally help the organization understand storage performance and will show incremental improvements across all systems—without guessing and without wasteful spending. Storage array–based snapshot or backup serves to offload those other bottlenecked resources. The difference in time/effort/efficiency/money is really big; snapshot is not just for large systems anymore. The beauty of virtual desktop and shared storage is the ability to manage just one desktop, which everyone uses. In the right situation, solid state device (SSD) is a viable and financially responsible alternative to 15K rpm hard disk drive. In the wrong use case, SSDs are a waste of money. E-mail can grow uncontrollably without quotas and some motivation for each person to manage their own mailboxes. The approach is to establish e-mail quotas and coach users to use personal folders and implement personal computer backup.
