Solid State Drives for IBM BladeCenter and System x 
servers
IBM System x at-a-glance guide
IBM® Solid State Drives (SSDs) use nonvolatile flash memory rather than spinning magnetic media to 
store data. Designed for enterprise blades and servers, the SSDs leverage the extensive history of IBM of 
meeting enterprise customer expectations in product development, qualification, and ongoing support on 
a worldwide basis. IBM offers the highest quality enterprise storage devices for enterprise computing 
environments.
IBM SSDs deliver the performance, power, size, and reliability required for BladeCenter® and System x® 
application servers. For cost-effective reliability and endurance, and to let customers chose the correct 
drive to meet business requirements, the IBM SSD family offers both SLC and enterprise-grade MLC 
technology. With up to 200 GB capacity in a 1.8-inch form factor, this powerful drive provides data loss 
protection upon power failure. In addition, IBM SSDs support the SATA interface, meaning that there are 
no compatibility issues. Figure 1 shows a 1.8" solid state drive.

In terms of I/O operations per second, SSDs can be used in enterprise environments to replace multiple 
traditional spinning disks, thereby improving application performance, power consumption, reliability, and 
the total cost of ownership. However, SSDs can also be used as a fast virtual memory paging device to 
reduce the need for more expensive memory DIMMs, which can lead to reduced server acquisition costs.  
SSDs simplify local storage infrastructure to help maintain overall maintenance and cooling cost, while 
providing remote storage solutions for end-to-end data availability as part of the enterprise ecosystem. 
SSDs are an appropriate solution for local OS booting, read-intensive applications, and some local 
storage space. Having originally been developed for the telco and federal marketplace, these 
SATA-based drives are highly rugged and reliable, and consume very low power. Increasingly, solid state 
storage is becoming a practical component in balancing datacenter cost, reliability, and manageability.
