Chapter 2
Checking the Server Environment
Connection to servers is possible in the following environments.
Check the "Server Support Matrix" for server environment conditions.
2.1 Servers
For supported servers, refer to "Server Support Matrix" and the following URL:
http://hcl.xensource.com/
If a logical unit (LUN) of the ETERNUS DX storage systems is used as a boot disk, refer to "Server Support
Matrix" to check the server environment.
2.2 SAS Cards
Refer to the "Server Support Matrix".
2.3 Connection Compatibility of ETERNUS DX Storage Systems to
XenServer Host
Refer to the "Server Support Matrix".
2.4 Virtual Machine
For details on the procedure and notes about installing a Virtual Machine that is supported by XenServer,
refer to the manuals that can be obtained on the following Citrix web-site:

Notes
Note the following issues when connecting the ETERNUS DX to a server.
3.1 Installation Notes
•To ensure reliable access to ETERNUS DX storage systems, multipath configuration is recommended.
•Setting up multiple access paths between the server and the ETERNUS DX storage systems, then using the
XenServer multipath, provides improved access redundancy.
•Enable the virtualization support functions (Intel VT or AMD-V) of the server before installing XenServer.
For details on the settings, refer to the relevant manual of the server to be used.
•Install XenServer when the ETERNUS DX is not connected to the server.
•The ETERNUS Multipath Driver does not need to be installed on the XenServer Virtual Machine. The Xen-
Server multipath provides path redundancy.
•When multiple paths are used, a multipath driver must be set. If a multipath driver is not set, the XenServ-
er multipath does not perform proper load balancing for the ETERNUS DX.
•Before setting a multipath configuration, create Storage Repositories for all the LUNs that exist in the
ETERNUS DX.
3.2 Operating Notes
•If a path error occurs in a multipath configuration using XenServer, the status of the failed multipath may
not be displayed. The status is displayed again when the failed path recovers.
•When XenServer is managed and operated with XenCenter, multipath errors may not be detected properly
by XenCenter. When checking multipath status, also check the status on the XenServer host side.
3.3 ETERNUS DX Setup Notes
•Host Response must be set before the ETERNUS DX is connected to the XenServer host.
•Even if the Eco-mode of the ETERNUS DX is enabled for a multipath configuration with XenServer, disk mo-
tors may not stop according to the Eco-mode settings.
