IBM is claiming that enhancements to its storage virtualisation engine software extend its reach to greater distances,...
greater speeds and a greater number of platforms. The IBM System Storage SAN Volume Controller 4.1 (SVC) includes a number of new technologies, including one that IBM says is designed to help organisations virtualise their infrastructures more efficiently and reduce costs over longer distances. In the wake of regional disasters, such as Hurricane Katrina, IBM believes that businesses are increasingly seeking ways to support continuing IT operations by placing the datacentres that share resources at greater distances than in the past.
Thus, IBM has added a new global mirroring function designed to help customers virtualise data at locations of greater than 100 miles. As well as being faster, the company believes it can also perform the task more cost effectively than previously.
Ultimately, IBMO regards the announcement as further proof of its leadership in storage virtualisation. IBM has already signed up more than 2,000 SVC customers who, it says, are virtualising more than 15 petabytes of data.
Research firm IDC has recently reported that the installed base of appliance-based, virtualised networked storage capacity was 28.1 petabytes at the end of 2005. Based on this information, IBM calculates that SVC manages more than half of the appliance-based virtualised storage capacity in the market today.
In addition to the business continuity enhancements, SVC 4.1 also supports 4Gbps (gigabits per second) environments and has extended capabilities to virtualise data on nearly 80 different disk systems.
IBM SVC 4.1 will be available from 23June 2006 with combined hardware and software list pricing starting at around $42,500.
