• Feature number 8340 must be selected and supports only SFF disks or SSD; 3.5-
inch drives are not supported with feature 8340:
– Feature number 1878 must be selected.
– One of feature numbers 1882, 1883, 1884, 1885, 1886, 1888, 1890, or
1909 must be selected (no disks/SSD are required if feature number 0837 is
selected).
– If connection of a feature 5886 EXP12S drawer is desired using the external
SAS port on feature 8340, feature number 3668 or 3669 is required.
– If tape device feature 5619 is installed in the half-high media bay, feature 3656
must be selected.
– If a tape device feature 5746 or 5661 is installed in the half-high media bay,
feature 3657 must be selected.
• Split DASD backplane support requirements:
– High-function DASD backplane (#8340, or follow-on).
– SAS Cable, DASD Backplane (Split) to Rear Bulkhead (#3669). Feature 3669
replaces feature 3668 in this configuration.
– SAS Adapter (#5900, #5901, #5912, or follow-on).
– External SAS cable.
– SAS Cable feature 3669 is not available with feature 2145 (IBM i).
• Solid State Drive (SSDs)(#1890, #1909, #3586, #3587) support restrictions:
– SFF features 1890 and 1909 are supported in the Power 750 CEC.
– 3.5-inch features 3586 and 3587 are not supported in the Power 750 CEC.
– SSDs and disk drives (HDDs) are not allowed to mirror each other.
– SSDs are not supported by features 5900, 5901, 5902, and 5912.
– A maximum of eight per feature 5886 drawer is allowed. No mixing of SSDs and
HDDs is allowed in a feature 5886. A maximum of one feature 5886 EXP12S
drawer containing SSDs attached to a single controller or pair of controllers is
allowed. A feature 5886 containing SSD drives cannot be connected to other
feature 5886s. A feature 5886 containing SSD drives cannot be attached to the
CEC external SAS port on the Power 750.
– In a Power 750 with a split backplane, SSDs and HDDs may be placed in either
"split" but no mixing of SSDs and HDDs within a split is allowed. IBM i does not
support split DASD mode.
– In a Power 750 without a split backplane, SSDs and HDDs may be mixed in any
combination. However, they cannot be in the same RAID array.
• DASD/Data Protection -- if IBM i (#2145) is selected, one of the following is
required:
– Disk mirroring (default) -- requires feature 0040, 0043, or 0308
– SAN boot (#0837)
– RAID -- requires feature 5679 and either feature 0041 or 0047
– Mixed Data Protection (#0296)
