Maximum number of files on a volume
about 4.2 billion (4,294,967,296)
What is a LUN?
a logical unit number is an address for an individual disk drive and by extension, the disk device itself
List limitations of Xsan volumes (such as maximum size, maximum number of LUNs)
Xsan supports volume sizes of up to 2 petabytes (PB) and billions of files per volume
Describe the performance implications of: having multiple storage pools per volume having multiple LUNs per RAID controller expanding a volume by adding LUNs to a storage pool expanding a volume by adding storage pools to the volume
You can set up storage pools that have different performance or recoverability characteristics and assign folders to them using affinities.…
Given a block size, stripe breadth, and number of LUNs, describe the write characteristics of an Xsan storage pool
Using Xsan administration tools, you can pool LUNs with identical size, performance, and data protection properties
