High Capacity Low Cost Drive Summary

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 Two failures with traditional RAID protection loses whole data set New Algorithms required

Market Overview and Trends Forecasted SCSI to SAS transition drivers Ability to use SATA or SAS depending upon need Parallel vs Serial Architecture Cable Length and bulk Low cost infrastructure Performance 2Gb to 4 Gb transition drivers Ease of Migration (2Gb / 4Gb interchange Performance increase Faster Controllers Faster drives Enclosure trends 2U 3.5” and 2.5” High density Long Term Trends RAID commoditization Raid offload AS and new architectures

SCSI to SAS Transition Internal DrivesInternal ArraysMainstreamEntry RAID 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 Q  SAS becomes the mainstream by Q2 2007, with SCSI still commanding a presence.  Very gradual and cautious take up of SAS Drive Vendor View:  SAS drives begin to ramp in Q  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.
