Power Systems flash memory solutions

SAS SSD and high performance SSD drawers

The SAS bays located in the front of a Power server can be occupied by either an HDD or SDD or the two can be mixed in various quantities. This is a versatile and relatively inexpensive option. The SSD can be serviced from the front of the server and can be non-disruptively added in single drive increments as long as SAS bays are available. SAS SSD are an excellent solution as long as a sufficient number of bays are available. If more capacity and performance is required then an external I/O drawer combined with high performance SAS RAID adapters or a SAN-attached system should be considered. The I/O drawer can be populated with the appropriate number of SSD to meet capacity and performance requirements. SSD located in the server bays or in I/O drawers are broadly supported across the Power Systems portfolio of servers and operating systems (AIX, Linux, IBM i). These solutions also offer enterprise reliability, availability, and serviceability features required by Power Systems customers. These solutions also support most of the widely used RAID data protection schemes.

Flash PCIe Adapters

The availability of PCIe Flash provides even more options for the Power server. Clients that have already loaded up their drive bays with SAS HDD can add PCIe Flash into the mix of internal storage as a great way to accelerate applications and improve server efficiency. IBM’s PCIe Flash Adapters present another storage volume to the operating system making it very easy to integrate into existing applications. The IBM Flash Adapter 90 provides extremely low latency, even better than SAS SSD. Additionally, the Flash Adapter 90 has IBM’s Variable Stripe RAID™ feature which protects data, adapter performance, and capacity even in the unlikely event a NAND flash chip experiences a failure.
