Long Term Trends for RAID Technology

• Raid Commoditization
• Basic function well understood
• RAID, Failover / Fail Back, Drive rebuild, Cache
• Several low cost vendors with Good Enough
  Solutions
• Prices and Costs falling steadily
• Raid Offload
• Basic feature function being pushed into silicon
• Single chip solutions coming from several vendors
• Ivivity, Istor, Aristos
• Removes RAID engine as bottleneck
• Firmware features now in silicon
• Huge improvement in I/O rates
• Performance under failure
• None shipping in Volume yet
• Large Disk Drive RAID rebuild issues RAID 6
  RAIDn
• Rebuild times on failure can be measured in days
• Probability of a second failure relatively high

SCSI to SAS Transition

• IDC View
• Gradual take up of SAS in a low cost
  server environment.
• Adoption into arrays by late 05 in direct
  attach environments.
• Entry RAID systems emerge Q4 2006
• SAS becomes the mainstream by Q2 2007, with
  SCSI still commanding a presence.
• Very gradual and cautious take up of SAS

Entry RAID

• Drive Vendor View
• SAS drives begin to ramp in Q4 2004.
• By Q1/2 2005, SAS drives are common in
  internal arrays and driving a rapid take up.
• Entry RAID systems are implemented in
  volume by late 2005
• SAS becomes the mainstream by early 2006
• A rapid adoption of SAS due to the
  performance and cost saving benefits over
  Parallel SCSI.

Enclosures

• 2U Enclosures
• Will likely be the standard for 3.5 SAS
  enclosures
• Lower cost per unit
• Lower increment of capacity
• Similar to 14/16 on a per slot cost basis
• Expected to be the standard for 2.5 enterprise
  systems
• Very high I/O density (5 to 6k I/Ops)
• Very low cost per slot (Similar overall cost to
  3U wit 2x the slot count)
• High storage density, With 144GB drives over 4TB
  in 2U
• Internal Rack JBOD 2.5 will be 1U with 10 or 12
  drives
• High Density Enclosures coming from several
  vendors
• All have design compromise
• Top Loader (Xyratex, ATA Beast)
• Front loader (multiple drives per carrier)
• Power issue for non-SATA drives for greater than
  40 drives
• High density for storage
• Some cost per slot savings
