IBM ES8K 1.9TB SSD Read Intensive SAS 4k SFF-3 eMLC4 Power IBM i iSeries
Custom Field 4 (MPN): 00LY374
IBM ES8K 1.9 TB SAS 2.5-inch (SFF) read intensive SSD is formatted in 4k byte sectors and mounted on a 2.5-inch SFF-3 carrier/tray to fit a IBM POWER8 system unit. The IBM ES8K SSD is rated at 6Gb/s, but actual performance will vary based on many factors for including IBM i customer workloads. The IBM ES8K has CCIN of 5B20, 00LY374 part number, and has an actual capacity is 1.86 TB. The IBM ES8K SSD is designed for read intensive workloads with light write activity. Approximately 3,394 TB of data can be written over the life of the ES8K SSD, but will vary based on IBM i workloads. After the warranty period, if the maximum write capability is achieved, the drive's replacement is not covered under IBM maintenance.
The ES8J and ES8K SSD are physically identical solid state drives, but use different feature codes to for OS type. The ES8J indicates usage by IBM AIX, Linux or VIOS, and the ES8K indicates usage by IBM i.
Limitations: The drive is mounted on a SFF-3 carrier/tray and does not physically fit into an expansion unit such as the
EXP24S's SFF-2 bays. JBOD formatting of 4096 byte sectors is not tested or supported. Drive cannot be reformatted to 5xx byte sectors. 5xx and 4k drives cannot be mixed in the same array.
IBM i Power8 servers running IBM i OS400 7.2 TR4, 7.3 or higher use a new 2.5" Read Intensive SAS SSD. This drive is intended to provide a lower cost per TB of SSD storage in a space-efficient footprint. Like all SSDs, performance is superior to hard disk drives (HDDs). Use the SSD Fuel Gauge to monitor the number of writes that are made to the drive. The SFF-3 carriers are for use in the CEC gen3 bays. The SFF-2 carriers are for use in the gen2 slots in the EXP24S SFF Gen2-bay Drawer EL1S. In addition, IBM i Virtualization configurations are supported for IBM i 7.3, 7.2 and 7.1, but for IBM i 7.1 it is client support only and the client has a size limit of 1.2 TB.
