, or you can create vdisks manually. TIP: Best practices for creating vdisks include: • To maximize capacity, use disks of similar size. • For greatest reliability, use disks of the same size and rotational speed. • For storage configurations using many disks, create a few vdisks each containing - HP MSA 2040 | HP MSA 2040 SMU Reference Guide (723981-001, June 2013) - Page 18
best practice is to designate spares for use if disks SAS disks, you might have vdisks that contain both types of disks. These are called heterogeneous or mixed vdisks.

The external port may be a port in an I/O adapter (such as an FC HBA) in a server. The controllers automatically discover hosts that have sent an inquiry command or a report luns command to the storage system. Hosts typically do this when they boot up or rescan for devices. When the command from the - HP MSA 2040 | HP MSA 2040 SMU Reference Guide (723981-001, June 2013) - Page 20
into a different enclosure, the volume's vdisk can be reconstructed and the mapping data is preserved. The storage system uses Unified LUN Presentation (ULP), which can expose all LUNs through all host ports on both controllers. The interconnect information is managed in the controller firmware. ULP - HP MSA 2040 | HP MSA 2040 SMU Reference Guide (723981-001, June 2013) - Page 21
You can add a management object to obtain information from a remote storage system. This allows a local system to track remote systems by their network-port IP addresses and cache their login credentials - the user name and password for a manage-level user on that system. The IP address can then - HP MSA 2040 | HP MSA 2040 SMU Reference Guide (723981-001, June 2013) - Page 22

protection in a single-controller storage system An MSA 2040 storage system can be purchased or operated with a single controller. Because single-controller mode is not a redundant configuration, this section presents some considerations concerning data protection.
