Business Class vsStandard Class Cabling
�Business Class Cabling
–Is a different hardware configuration
were the DS8800 is delivered with
all the cabling which connects the
disk drives to their appropriate
device adapter
–Provides the capability to skip disk
enclosures
–All upgrades are non-disruptive
•Changing Business Class to Standard
Class is disruptive

Storage efficiency with space-saving design
•Client feedback is very positive on space-saving design
•Small-form
-factor drives
•High-density drive enclosures
•Almost double the drives in same frame footprint
•Benefits
•More effective consolidation can lower operating costs
•Support m
ore workloads with smaller footprint
•Reduce number of systems to m
anage
•Reduce power and cooling costs
Saving m

Extent Allocation M
ethod Review
•Blue, Yellow
Yellow&
TurquoiseVolumes
are Rotate by Extent
•RedVolume is
Rotate by Volume
•With R6.0, EAM defaultchanges from Rotate by Volume to
Rotate by Extent
Change Default Extent Allocation Method
©2010 IBM Corporation
18
Change EAM default to Rotate Extents
�No change to DSCLI syntax, but …
�Customer’s scripts may change behavior if EAM not specified
–If not explicitly specified, EAM on new/expand volumes will default to
rotate extents instead of rotate volumes
–Note that current EAM only applies to future extent allocations
•DSCLI may not display EAM of extents already allocated
�Default is specific to the R6.0+ Release Bundle, not the DSCLI
–Default for DS8000 boxes with R6.0 and later is rotate extents
–Default for DS8000 boxes prior to R6.0 is rotate volumes
�CE may change default back to rotate volumes
