Xsan: Compatibility of Xsan metadata controllers (MDCs) and clients

In some situations, you can use clients and metadata controllers with different versions of Xsan in the same SAN.



  1. In order to enable case insensitivity, all members of the SAN must be running Xsan 2.3 or later.
  2. Mac OS X v10.5-based Xsan 2.2.1 clients cannot be used with an Xsan 2.3 MDC. Mac OS X v10.6 is required on Xsan 2.2.1 clients of an Xsan 2.3 MDC.
  3. In order to use native extended attributes, all members of the SAN must be running Xsan 2.2 or later.

This chart shows the minimum Xsan client version that is compatible with the Xsan version on the metadata controller. The versions of Xsan and OS X on the metadata controller must the same as, or later than, the latest versions on a client.

MDC version Minimum client version
Xsan 3.0 - 3.1 Xsan 2.2.2 (see note 1)
Xsan 2.3 Xsan 2.2.1 (see notes 1 and 2)
Xsan 2.2 - 2.2.2 Xsan 2.1.1 (see note 3)
Xsan 2.0 - 2.1.1 Xsan 1.4.2
Xsan 1.4.2 Xsan 1.3
