File system improvements in vSphere 5 enhance storage scalability and lay the groundwork for flashy features like Storage DRS

No one doubts that virtualization has made managing centralized storage environments far easier than managing an equivalent mass of physical SAN-attached servers. But as businesses spin up new VMs and create data at breakneck speeds, the limitations of VMware's VMFS3 clustered file system have often yielded complex, hard-to-manage storage configurations.

Thankfully, with vSphere 5, VMware has upgraded the file system with a number of substantial improvements. Although some lmitations remain, the new VMFS5 file system provides both greater scalability and easier management.

Bigger and badder

The most visible change in VMFS5 is an increase in the maximum VMFS volume size from 2TB to approximately 64TB. In older versions of vSphere (and VMFS), you'd need to provision a series of partitions, or extents, that would be concatenated together to form a volume of up to 64TB using 32 separate SAN volumes, each containing a 2TB extent.
