The IBM EJ0C Storage Backplane with HI Performance plus 2x24-Port provides Power9 E950 customers with a new storage option, along with the existing three storage IBMs (EJ0B, EJBB, EJSB). The IBM Power9 E950 server has eight SFF (2.5 in.) SAS bays for HDDs or SSDs, plus four NVMe 2.5-inch bays. One or two PCIe SAS adapters support the SAS bays. One of these SAS options must be selected:

• Storage Backplane with HI Performance plus 2x24-Port (EJ0C).
• DASD Backplane with no HDD/SDD drive selected. No PCIe SAS adapter is required (EJ0B).
• Base DASD backplane together with one SAS PCIe adapter and select SAS drives (EJBB).
• Split DASD backplane together with two SAS PCIe adapters and select SAS drive (EJSB).

NVMe drive options can be selected with any of the above SAS options.

The base and the split backplane options provide SFF-3 SAS bays in the system unit. These 2.5-inch or small form factor (SFF) SAS bays can contain SAS drives (HDD or SSD) mounted on a tray or carrier. Thus, any drives that are designated for SFF-1, or SFF-2 bays do not fit in an SFF-3 bay. All SFF-3 bays support concurrent maintenance or hot-plug capability. These backplane options support HDDs or SSDs or a mixture of HDDs and SSDs in the SFF-3 bays. If mixing HDDs and SSDs, they must be in separate arrays.

The base and the split options can offer different drive protection options: RAID 0, RAID 5, RAID 6, or RAID 10. RAID 5 requires a minimum of three drives of the same capacity. RAID 6 requires a minimum of four drives of the same capacity. RAID 10 requires a minimum of two drives. Hot spare capability is supported with RAID 5, RAID 6, or RAID 10.

 Hardware Enhancements for both POWER9 and POWER8 provided with V7R4

IBM Enterprise SSD: 387 GB, 775 GB, and 1.55 TB
The IBM Enterprise SAS SSDs are available in 387 GB, 775 GB, and 1.55 TB capacities, and are 2.5-inch SFF drives that can be installed in the IBM Power9 or Power8 system unit SAS bays (SFF-3) or in EXP24SX SAS bays (SFF-2) attached to a Power9 or Power8 server. The new IBM Power9 Enterprise SSDs include the latest 3D NAND technology flash memory, which improves enterprise-class reliability, endurance, and capacity characteristics. The new IBM Enterprise SSDs build upon a heritage of performance and endurance to provide a better value proposition to users of Power9 and  Power8 servers. The IBM Power9 or Power8 servers that support the new enterprise SAS SSDs in the system unit are E950, L922, S914, S922, S924, H922, H924, S812L, S822L, S824L, S814, S812, S822, S824, E850, and E850C servers.

The SFF-3 SAS bay in these servers uses an SFF-3 carrier/tray, on which the SAS drive is mounted. Other model POWER9 and POWER8 servers E980, E880C, and E870C do not have SAS bays in their system units and therefore cannot support enterprise SFF-3 SSDs. When attached to a Power9 or Power8 server, the EXP24SX I/O drawers can hold up to 24 SAS SSDs. The EXP24SX SAS bays use an SFF-2 carrier/tray, on which the SAS drive is mounted.

The new IBM Enterprise SSDs are run by the integrated SAS controllers in the Power9 or Power8 system unit or by PCIe3 SAS adapters. The IBM SSD configuration rules, maximums, limitations, and capabilities of these PCIe3 SAS adapters and integrated SAS controllers are unchanged. You can mix IBM enterprise SSDs and earlier SSDs on the same controller or adapter, as well as mix them in the same array.

The IBM SSD rules are unchanged:

• Do not mix different size capacities such as 387 GB and 775 GB in the same array or mix 775 GB and 1.55 TB in the same array.
• Do not mix 4k and 5xx drives in the same array.
• The largest enterprise SSD supported in the 4-core Power S814/S914 server is 387 GB.
• Do not mix SSDs and HDDs in the same array unless it is an Easy Tier array.
• 4k drives are not supported on servers older than POWER8.

The new IBM Enterprise SSD features for V7R4 are as follows:

• 387 GB IBM Enterprise SSD, ES90/ES91 (SFF-3 and 4k), ESGT (SFF-3 and 5xx), ES94/ES95 (SFF-2 and 4k) and ESGV (SFF-2 and 5xx)
• 775 GB IBM Enterprise SSD, ESNC/ESND (SFF-3 and 4k), ESGX (SFF-3 and 5xx), ESNA/ESNB (SFF-2 and 4k) and ESGZ (SFF-2 and 5xx)
• 1.55 TB IBM Enterprise SSD, ESNG/ESNH (SFF-3 and 4k), ESNE and ESNF (SFF-2 and 4k)

IBM Mainstream SSD: 931 GB, 1.86 TB, 3.72 TB and 7.45 TB
The new IBM mainstream SAS SSDs are available in 931 GB, 1.86 TB, 3.72 TB and 7.45 TB capacities, and are 2.5-inch SAS SSD mounted on an SFF-3 carrier/tray for a Power9 or Power8 system unit or mounted on an SFF-2 for an expansion drawer such as the EXP24SX drawer when attached to a Power9 or Power8 server. The IBM mainstream SSDs are designed to provide a lower cost per terabyte of SSD storage in a space-efficient footprint. The IBM SSDs are formatted to use 4224-byte (4k) sectors and does not support the 4k JBOD 4096-byte sector, and does not use the 512-byte or 528-byte (5xx) sector formatting.

When the IBM SSDs are in Power9 or Power8 system units with SAS SFF-3 bays, the drive is run by the integrated SAS controller such as found in Power9 E950, L922, S914, S922, S924, H922, H924, S812L, S822L, S824L, S814, S812, S822, S824, E850, and E850C servers. When placed in the EXP24SX (SFF-2) storage enclosure, the IBM SSDs are run by a PCIe3 SAS RAID adapter, such as the feature EJ0L, EJ14, EJ0J, EJ0M, EL3B, or EL59. These PCIe3 controllers support 4k drives on Power9 or Power8 servers. Earlier IBM Power generation SAS controllers do not support 4k drives.

When placed in an SSD array of one of these PCIe3 controllers, the array must be all mainstream SSDs or all nonmainstream SSDs. A SAS controller can currently run both 4k and 5xx drives, but they must be in separate arrays. Drives in an array should be the same or similar capacity. HDDs and SSDs can only be mixed in the same array when part of an Easy Tier® array (RAID 5TS, RAID 6T2, or RAID 10T2) provided by SAS RAID controllers such as the feature EJ0L or EJ14 or Power9 or Power8 integrated backplane controllers.

Like all IBM SSDs, the performance of the 931 GB, 1.86 TB, 3.72 TB, and 7.45 TB mainstream SSDs are excellent compared to a disk drive (HDD). Read performance is on par with higher write endurance IBM SSDs such as the enterprise SSDs. Write performance when compared to enterprise SSDs is somewhat slower but still more than 25 times that of a standard 15K HDD. As with any drive, either HDD or SSD, the number of drives is still a factor in achieving satisfactory performance, especially for IBM i.

These are mainstream drives and are not suitable for write-intensive workloads. Write-intensive workloads are those that write more to the drive each day than its rated capacity. Assuming a typical heavily random workload at about 3394 TB of writes to the drive, it will be at its maximum projected write capability. Writes past the drive's maximum write capacity will continue to work for some period of time, but much more slowly. A Predictive Failure Analysis message will indicate that it is time to replace the drive. If the predictive failure is ignored and writes continue to be sent to the drive, eventually the drive will be unable to accept write commands and will accept only read commands for a period of time. A failed write will result in a more serious error message indicating that the drive must be replaced.

The nature of the workload has a great impact on the maximum write capacity. For example, if a high percentage of more sequentially oriented writes is used instead of random writes, the maximum write capacity can be significantly larger. The user should occasionally check to see what percentage of the drive's write life remains and adjust the workload or drive assignment as it makes sense to do so. Checking is done by inspecting the SSD Mainstream Fuel Gauge. This capability is available through IBM AIX, IBM i, and Linux®. The query or command to view the information varies by operating system. Check the remaining life of the mainstream drives individually, even if all are in the same array.

DWPD (Drive Write Per Day) rating is 1 calculated over a 5-year period. The approximate lifetime Total Bytes Written (TBW) in Terabyte (TBB) supported by each drive capacity are as follows: 931 GB = 1,700 TBW, 1.86 TB = 3,399 TBW, 3.72 TB = 6,799 TBW, 7.45 TB = 13,601 TBW.

The new IBM Mainstream SSD features for V7R4 are as follows:

• 931 GB IBM Mainstream SSD for IBM i, ESJ8/ESJ9 (SFF-3 4k) and ESJ0/ESJ1 (SFF-2 4k)
• 1.86 TB IBM Mainstream SSD for IBM i, ESJA/ESJB (SFF-3 4k) and ESJ2/ESJ3 (SFF-2 4k)
• 3.72 TB IBM Mainstream SSD for IBM i, ESJC/ESJD (SFF-3 4k) and ESJ4/ESJ5 (SFF-2 4k)
• 7.45 TB IBM Mainstream SSD for IBM i and Power9 only, ESJE/ESJF (SFF-3 4k) and ESJ6/ESJ7 (SFF-2 4k)

The IBM EJ1N and EJ1P PCIe1 SAS Tape/DVD Dual-port 3 Gb x8 Adapters are available for the Power E980 server. It supports the attachment of SAS tape and DVD using a pair of mini SAS 4x connectors. The IBM EJ1N and EJ1P adapter can be used for external tape drives, which are not supported on the newer and faster 4-port 6 Gb PCIe3 adapter (see #EJ10, #EJ11, #EL60). The adapter supports external SAS tape drives such as the DAT72, DAT160, LTO™-4, LTO-5, LTO-6, and LTO-7 found in the IBM multimedia drawers such as the 7226-1U3 or 7214-1U2 or tape units such as the TS2240, TS2340, TS3100, TS3200, and TS3310. Other removable media devices supported include IBM SAS/SATA DVD-ROM/RAM drives.

The IBM EJ1N and EJ1P SAS adapter-to-enclosure (AE) 3 Gb cables with mini-SAS connectors are used to attach these drives. See features 3684 (3 meter) and 3685 (6 meter). The same AE cables can often alternatively be ordered under the tape enclosure or multimedia drawer.
