–Initial release requires all disks encryption capable
–Enterprise Class Disk Features Supported
�Entire Storage Facility is ‘encryption-capable’or not ‘encryption
capable’.
�Each Storage Facility Image on encryption-capable Storage Facility can
be independently enabled or disabled for encryption.
�TKLM unwraps single key stored on DS8000 to unlock the entire
Storage Facility Image.

[ [[[104 writes/cell (Cameras, iPods,
etc.)
�Coping strategies
–Wear leveling, over-provisioning, bad block m
anagement, ECC,
compression, write elim
ination, …

1 TB SATA 7200 RPM Drive Support
�New 1 TB SATA drives will become
available on March 6, 2009
�Enabled through new feature code
specifications in megapack(16)
drive increments (see following
chart for list of feature codes)
�Scales DS8000 to 1,024 TB physical
capacity when fully populated with
all 1 TB SATA drives (5 frames)
�All models of the DS8000 family are
supported (2107, 2421, 2422, 2423
and 2424)

When to Consider SATA
�Tier-1 Storage
–When looking for low cost per gigabyte with lower expectations of
perform
ance
–Streaming applications where transfer rate is m
ore important than
seek times
–Applications with low IOPS perform
ance requirements
�Tier-2 Storage
–Disk based near-line storage between disk and tape
–Disaster recovery target for remote replication
–Fixed content / Managed Retention data
–Temporary work space for short-term
processing
–Consolidation of tier-2 subsystems
IBM Storage and Technology Group

3232
SATA Drive Requirements and Limitations
�1 TB SATA drives will require at a minimum licensed machine code
(LMC) level 5.4.2xx.xxx (bundle version 64.2.xx.xx)
�Only RAID-6 or RAID-10 will support the SATA drives
–No RAID-5 support at GA
–RPQsfor RAID-5 support m
ust be submitted through norm
al
channels
–RAID-6 requires DA-2 device adapters
�Not intended for Space Efficient FlashCopyrepository because of
the lower performance and reliability characteristics
�A SATA drive will not be used as a spare for FC or FATA drives
–Perform
ance of the entire array would be degraded
IBM Storage and Technology Group

SATA Design Architecture
�SATA architecture uses a 512 byte physical sector size
�DS8000 device adapters require 524 bytes sector size
�SATA uses a different protocol compared to fibrechannel
�IBM elected to utilize a bridge card
•Translates fibre
channel protocol to SATA protocol and vice
versa
•Bridge card is an EmulexBRG436-I
•Connects to Hitachi Gemini-K 1 TB SATA drive
•Requires padding to align blocks to sector size
•Each SATA drive has its own dedicated bridge card

Sector Mapping Capacity Tradeoff
�Reduced disk capacity due to extra padding added
on every alignment unit. The estimated loss of
disk capacity is as follows:
–128 block alignment –0% capacity loss
–64 block alignment –0.76% capacity loss
–32 block alignment –0.76% capacity loss
–16 block alignment –3.68% capacity loss
–8 block alignment –9.03% capacity loss
�DS8000 will utilize a 8/9 sector remapping
–Every 524 byte block aligns at 512 byte sector
boundary on every 8 logical blocks due to padding

3838Sector Remapping
�Higher performance (8/9) remapping was chosen
over higher capacity (128/131).
�Results in significantly higher write performance
�However 1 TB SATA drives will have about 900 GB
of usable capacity
�Formatted arrays are quite large

4444Intermix of 1 TB SATA Drives
Intermix of 1 TB SATA Drives
�The same rules governing intermix of FibreChannel
and FATA drives apply to SATA drives
�Intermix of FibreChannel, FATA or SATA drives on the
same DA pair is allowed.
�1 TB SATA drive can not be used as a spare in the
event of a failure of FC or FATA drive
�If a spare occurs, the rank will take on the attributes of
the slowest drive in the rank (no change in how this
operates)
�Neither FibreChannel nor FATA drive can serve as a
spare for the 1 TB SATA drives due to their smaller size
