Heterogeneous Storage System Support - HP StorageWorks 4000/6000/8000 - Enterprise Virtual Arrays Reference Manual

number
3 Shared usage of HP Continuous Access EVA-configured storage systems by non-HP Continuous
Access EVA-configured servers (for example, a single HBA or an operating system without
nl
multipathing support) or non-HP Continuous Access EVA-supported operating systems is not suppor-
ted.
4 For information about supported versions of clustering software and Secure Path, contact an HP
storage representative.
5 Each HP Continuous Access EVA implementation can contain 16 EVAs; each EVA is limited to 256
HBAs. With 2 HBAs per server, 128 servers are possible. Multiple HP Continuous Access EVA
solutions can exist in the same SAN, provided that no solution exceeds the 16-array limit, imposed
by zoning.
6 The maximum number of copy sets, DR groups, and remote copy sets is based on the EVA storage
system model and controller software version (see the HP StorageWorks Enterprise Virtual Array
compatibility reference). On all storage systems, the limit is the total number of DR groups and
copy sets that are either a source or a destination. When replicating across storage systems with
different limits, the lower limit applies to the storage system replication pair.
The HP Continuous Access EVA link supports mixed heterogeneous SAN, HP Continuous Access
7
EVA, and OpenVMS host-based shadowing traffic.
8 Two Storage Management Appliance Command View element mangers are required: one active
and one either active in standby mode or in powered-off, passive mode. The active appliance and
Command View EVA can be used for initial setup of HP Continuous Access EVA storage.
Management of the operational HP Continuous Access EVA environment is done through the HP
StorageWorks Replication Solutions Manager and other products installed on the Storage
Management Appliances.
For more information, see the HP StorageWorks Continuous Access EVA planning guide, HP
StorageWorks Continuous Access EVA release notes, and HP StorageWorks Continuous Access
EVA administrator guide.

Heterogeneous storage system support

HP supports HP storage products on shared hosts, and HBAs in solution environments that also have
third-party storage products. A third-party cooperative support agreement between HP and the third
party is required if HP will provide a single support point of contact that includes the third-party storage.
HP provides technical support for its products and cooperates with the third party's technical support
staff, as needed.
HP provides best-practices recommendations for connecting devices in the SAN (see
"Best practices" on page 417). These rules apply to configurations that include HP SAN storage products
and heterogeneous third-party SAN storage products:
Use zones to isolate HP storage ports from third-party storage ports.
Overlapping zones with multiple storage ports are not supported.
Third-party storage zones are governed by product-specific configuration guidelines (see the third-
party product documentation).
