Introducing The Storage Evolution

What come so mind when you think about storage? There’s so much to consider. Do you think of primary storage, the world where servers directly access their information via methods such as direct attached disk (DAS) storage area networks (SANs) and network attached storage (NAS). Do you think about secondary storage, the realm of backups and archives, virtual tape libraries (VTLs), automated tape libraries (ATLs) and long-term repositories (disks, optical platters, tapes or whatever makes sense at the time).

For me, I have four evolutionary topics mapped out. When I sit down to discuss where the action is taking place in storage, I can usually distill it down to four keys areas:

  1. Virtualization
  2. Deduplication
  3. Grid
  4. Encryption
