Performance and Optimization
A customer can reconfigure metavolumes. While the Symmetrix
system is online to the host, the customer can:
â—† Expand both concatenated and striped metavolumes.
â—† Convert an unused volume to a concatenated or striped
metavolume.
â—† Convert a populated volume to a concatenated or striped
metavolume.
Striping data across the multiple drives is designed to benefit random
reads by avoiding stacking multiple reads to a single spindle and disk
director. This scheme creates a large volume, but also balances the
I/O activity between the disk drives and the Symmetrix disk
directors.
