Specifications

Figure 33 shows an example of the display for the hardware service manager
(HSM) auxiliary storage hardware resource detail for the 2105 disk unit.
On an ESS, you can define the ESS LUNs as either protected or unprotected. From
an ESS physical configuration view point, all iSeries volumes are RAID-5 and are
protected within the ESS. When you create the iSeries LUNs using the ESS
Specialist, you can create them as logically protected or unprotected. Table 13
shows the disk capacity for the protected and unprotected models.

Performing Peer-to-Peer remote copy functions
This section describes the basic hardware and software requirements for an iSeries
host system. You can set up Copy Services on an ESS. A description of how to set
up the primary and secondary Copy Services servers follows this section.
