HP StorageWorks XP Command View Advanced Edition software Device Manager server installation and configuration guide (web version) (T1780-96078, March 2008)

• LAN cables, connections to the storage subsystem, and a 10/100 Ethernet LAN card that has
TCP/IP installed and available. (If the machine and the LAN cable are compatible with Gigabit
Ethernet, you can use a Gigabit-class card.)
• When using one Device Manager server, it is not possible to use separate storage partitions
with different storage administrator accounts. If you want to manage individual storage
partitions, a Device Manager server is required for each storage partition.
• The estimated installation time is about 10 minutes, for a new installation on a machine
configured as follows:
○ OS: Linux AS 4
○ Processor: Intel® Core
TM
2 (2.4 GHz)
○ Memory: 512 MB
4-1-2 Setting memory heap size according to the number of
managed resources
The following table shows the number of resources that can be managed by the Device Manager
server. We recommend that you operate the Device Manager server within these limits.
The default value in the table is used if you do not change the memory heap sizes of HBase
Storage Mgmt Web Service and the Device Manager server. The number of LDEVs in the table is
the total of the number of LDEVs for mainframes and the number of LDEVs for open systems. Also,
the number of security settings in the table is the total number of WWNs that are allocated to set the
security for LUNs in the storage subsystems managed by Device Manager.
Table 4-4 Maximum value of the number of resources that can be managed by the
Device Manager server
Resource Maximum setting Default
Number of LUNs 128,000 32,000
Number of
security settings
192,000 48,000
Number of LDEVs 128,000
(The maximum number of LDEVs for open systems only is
64,000.)
16,000
In an environment in which Device Manager is used, if the assumed number of resources exceeds
the default settings in the above table, you need to estimate the number of managed resources, and
then set the memory heap sizes of HBase Storage Mgmt Web Service and the Device Manager
server according to the estimated value.
The formula that can be used for estimating the number of managed resources is shown below.
When multiple storage subsystems are to be managed, estimate the number of managed resources
for each storage subsystem, and use the greatest value as a guideline. However, when creating
copy pairs, use the sum of the estimated values as a guideline, not the greatest value.
Formula:
number-of-managed-resources = number-of-LDEVs
X 2.5 + total-number-of-LUNs*
* total-number-of-LUNs = number-of-LDEVs
X average-number-of-LUNs-per-LDEV
If the number-of-managed-resources is 28,000 or greater or if an Out Of Memory error occurs while
you are using web client to perform an operation such as displaying a list of LDEVs, set the memory
heap size by following the procedures described in sections
4-1-2-1 and 4-1-2-2 .
