The following table describes the capacities listed in the License dialog box. Each capacity features
its total amount, the amount used, and the amount available.
Table 2 License capacities
DescriptionProperty
The amount of licensed capacity allotted for basic operations (for example, the
maximum size of all pools). See Table 1 on page 19).
Basic capacity
The amount of licensed capacity allotted for local replication (for example, the
size of all parents). If your license does not allow Business Copy operations, this
amount is zero (see Table 1 on page 19).
BC capacity
The amount of licensed capacity allotted for thin provisioning. If your license does
not allow thin provisioning operations, this amount is zero (see Table
1 on page 19).
TP capacity
The amount of licensed capacity allotted for remote replication. If your license
does not allow Continuous Access operations, this amount is zero (see Table
1 on page 19).
CA capacity
The number of DPM ports, four at a time, issued for a DPM group. There are a
total of 16 ports per DPM. One dual 4–port LTU turns on 8 ports (4 per DPM).
DPM port number
Zoning
Hosts and storage can be zoned to different DPM “quads” to distribute the load between available
DPM ports. To simplify the validation of the configuration, it is desirable to have the same hosts or
storage zoned to the same quad on each DPM. For example, hosts A and B could be zoned to quad
1 of both DPMs and hosts C and D zoned to quad 2 of both DPMs. This is called a symmetrical
configuration.
See “Zoning” on page 45 for a detailed description of how to incorporate zoning into your domain.
Adding a new array
The following guidelines must be observed when adding arrays to the domain:
• An array must be attached to both fabrics.
• Back-end zones are created as described in “Zoning” on page 45. Two sets are needed and are
defined as follows:
• Array to DPMs
• Array to VSM servers
• If adding the array also involves using a new DPM quad, add the new DPM quad to the VSM
server zones and verify that the DPM ports are licensed.
• Using the management interface of the new array, create or define DPMs and VSMs as hosts, and
then present the back-end LUs to the DPMs and VSMs. Each pair of quads should have a unique
host definition.
• Refresh the VSM software using the VSM refresh button. Once the new back-end LU is visible, use
it and others to create stripe sets, then create pools. Use the pools to create front-end virtual disks.
It is also important to understand the best practices for the vendor-specific storage arrays that are
configured behind the SVSP. Since much of I/O directed at the SVSP will pass directly through the
SVSP, optimizing the arrays based upon the I/O characteristics has the most value. It should also be
