Xsan 2 requires that Mac OS X version 10.5 or Mac OS X Server version 10.5 software be installed and will support qualified Fibre Channel switches from vendors such as Brocade, QLogic and Cisco, and RAID storage hardware including Xserve RAID and Promise VTrak E-Class RAID subsystems.Setting up Xsan is easier than ever, in OS X Mavericks. Xsan 2 has also been qualified with third-party RAID storage hardware from Promise Technology in configurations tuned and optimized for Xsan.Īpple has qualified Xsan 2 with Xserve, Mac Pro and Apple Fibre Channel PCI-X cards. In addition, Apple said that Leopard Server features such as iCal Server, Mail Server and Podcast Producer, can now integrate with Xsan 2 to supportĬlustered file systems, improving performance and scalability and reducing the impact of a service outage from the loss of any one server. Combining enhanced performance with Apple’s legendary ease of use, Xsan 2 makes it easier for first time users to set up and quickly deploy a SAN introduces MultiSAN, allowing users on a single workstation to access multiple SANs. “Now with Xsan 2, businesses can efficiently share and access their data faster and easier than ever before.” Apple today introduced Xsan 2, the first major upgrade to its easy to use, high performance, enterprise class Storage Area Network (SAN) file system for Mac OS X. “Tens of thousands of businesses, from small video post-production houses to large data centers and TV stations, use Xsan as their clustered SAN file system,” said Zelenka.
