Notes:
–Features 1995 and 1996 require feature 2053.
–When feature 2145, IBM i operating system, is selected, a minimum of two HDD/SSD is required.
–No internal HDD/SSD is required if feature 0837 (Boot from SAN) is selected. In this case, a Fibre Channel or Fibre Channel over Ethernet adapter must also be ordered.
•Power 710 requires one 1725 watt AC Power Supply (1 x #5603) and one power cord (1 x #6xxx); Power 730 requires two 1725 watt AC Power Supplies (2 x #5603) and two power cords (2 x #6xxx).
•Choose chassis type from:
–Power 710 requires one processor chassis (#7317).
–Power 730 requires two processor chassis (#7318).
•Choose Primary Operating System Indicator from:
–IBM i (#2145
–AIX (#2146)
–Linux (#2147)
Note: One nonfeaturized memory riser card is included in the base system. One additional memory riser card feature (#5265) can be ordered on the Power 710. Three additional memory riser card features (#5265) can be ordered on the Power 730.
RAID
There are multiple protection options for HDD/SSD drives in the SAS SFF bays in Power 710 and Power 730 system units or drives in
This HDD/SSD drive protection can be provided by AIX/IBM i/Linux software or by the HDD/SSD hardware controllers. Mirroring of drives is provided by AIX/IBM i/ Linux software. In addition, AIX/Linux supports controllers providing RAID 0, 1, 5, 6, or 10. IBM i integrated storage management already provides striping, so IBM i also supports controllers providing RAID 5 or 6. To further augment HDD/SSD protection, hot spare capability can be used for protected drives. Specific hot spare prerequisites apply.
An integrated SAS HDD/SSD controller is provided in the Power 710 and Power
730 system units and provides support for JBOD and RAID 0 for AIX or Linux. It is optionally augmented by RAID 5, RAID 6, and RAID 10 capability when feature 5268 is added to the configuration. In addition to these protection options, mirroring of drives by the operating system is supported. AIX or Linux supports all of these options. IBM i does not use JBOD and uses imbedded functions instead of RAID 10, but does leverage the RAID 5 or 6 function of the integrated controllers. Other disk/ SSD controllers are provided as PCIe SAS adapters are supported. PCI Controllers with and without write cache are supported. RAID 5 and RAID 6 on controllers with write cache are supported.
AIX/Linux can use disk drives formatted with 512 byte blocks when being mirrored by the operating system. These disk drives must be reformatted to 528 byte sectors when used in RAID arrays. Although a small percentage of the drive's capacity is lost, additional data protection such as ECC and bad block detection is gained in this reformatting. For example, a 300 GB disk drive when reformatted provides around 283 GB. IBM i always uses drives formatted to 528 byte. IBM Power SSDs are formatted to 528 byte.
