Planning: MD3600i Series Storage Array Terms and Concepts 51
• A unique LUN must be used by a host group or host server to access a virtual
disk.
• Not every operating system has the same number of LUNs available for use.

Host Types

A host server is a server that accesses a storage array. Host servers are mapped
to the virtual disks and use one or more iSCSI initiator ports. Host servers
have the following attributes:
• Host name—A name that uniquely identifies the host server.
• Host group (used in Cluster solutions only)—Two or more host servers
associated together to share access to the same virtual disks.
This host group is a logical entity you can create in MDSM. All host servers
in a host group must be running the same operating system.
• Host type—The operating system running on the host server.
Advanced Features
The RAID enclosure supports several advanced features:
• Virtual Disk Snapshots
•Virtual Disk Copy
• High Performance Tier
NOTE: Virtual Disk Snapshot, Virtual Disk Copy, and High Performance Tier are
premium features that must be activated separately. If you have purchased these
features, an activation card is supplied that contains instructions for enabling this
functionality.
