With SSD caching, the most frequently used data is stored on solid state memory placed between the system memory and hard drives. Because SSDs use no spinning disks and robotic arms, the storing and retrieving of data is accomplished with virtually no latency, speeding data access by orders of magnitude. In addition to the superior performance, SSD cache requires no separate tier to manage.
The IBM XIV SSD Caching option provides up to 6TB of fast-read SSD and is the latest in a string of advances that IBM has developed for the enterprise storage system over the last six months. In July, 2011, the company introduced the XIV Storage System Gen3, a new generation of the storage family that dramatically lowered the total cost of ownership and improved system performance by four times over the previous model.
With XIV Gen3, IBM also replaced the system’s Ethernet-based backplane with a high-performance InfiniBand backplane that increased the system’s internal bandwidth between modules by 40 times. Then in October 2011, IBM added 3TB disk drives to the system increasing system capacity by 50 percent.
“These latest enhancements to XIV Gen3 are great examples of IBM’s continued commitment to helping customers achieve business outcomes through smarter storage technologies. It boils down to saving the customer’s time and money with extremely efficient, easily managed, virtualized, and high-performing storage systems like XIV Gen3,” said Ireen Catane, Country Executive, Systems and Technology Group, IBM Philippines.
IBM also announced the ability to mirror data between previous versions of XIV and XIV Gen3 systems, which will ease data migration and help give customers the flexibility to repurpose their XIV models as disaster recovery backup systems.
Building on XIV Gen3’s remote monitoring capabilities, IBM announced the availability of XIV Mobile Dashboard for the Apple iPhone, which lets customers monitor XIV systems from virtually anywhere. The app will be available for download at no cost from the Apple Online Store. IBM released the XIV Mobile Dashboard for the Apple iPad® in October 2011.
