There is certainly no restrict on the amount of network shopper connections that can be implemented. Multiple RAID volumes may be shared (as much as 16 based on Apple documentation), with support for billions of data every quantity. More, volumes can be as massive as a couple of petabytes (PB).

What improvements are incorporated in Xsan a couple of?

Apple has included many refinements in Xsan 2, which include less difficult setup and deployment employing Xsan Admin 2. Workstations and servers can now discover numerous Xsan volumes simultaneously, because of improved MultiSAN assist.

Spotlight integration is now readily available across an Xsan SAN quantity, as assistance for Protect Flow and Swift Seem; these capabilities allow it to be simpler for enterprise end users to locate and accessibility information and details saved throughout Xsan-powered networks. Xsan also now boasts integrated help for new software for Mac OS X server functions, including Mail Server and Podcast Producer, which more enhances functionality and scalability in huge environments.
