To provide compatibility and interoperability, what properties does the Xsan implementation have? (is the file system case sensitive or insensitive, is it a forked file system?)
case-sensitive, single-fork file system.
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
Describe how to create an affinity in Xsan Admin
Affinities allow you to allocate different classes of storage to different purposes, without forcing users to adhere to annoying rules.…
Describe how to configure quotas and permissions on an Xsan volume
Disk quotas LDAP integration also makes it easy to manage disk space quotas. You can assign quotas to users, groups,…
Describe the benefits of using Directory Services with Xsan
Because Xsan is simply another file system, it adheres to the file system permissions built into Mac OS X, including…
Define block allocation size, stripe breadth, and Allocation strategy
Block Allocation Size: Stripe breadth: Allocation Strategy The allocation strategy you choose for a volume determines the order in which…
Describe the compatibility between Xsan and ADICs StorNext file system
In heterogeneous computing environments, you can add nonMac OS X clients to your Xsan network using ADICs StorNext File System.…
