.Part 3 Host and Storage System Rules HP SAN Design Reference Guide 785353-001

NOTE: 500 MB/s (4,000 Mb/s) of bandwidth per storage node pair needs to be allocated on
the 10 GbE network between the two locations. Network latency among storage nodes cannot
exceed 1 ms.
The two Fibre Channel fabrics between the two sites can be stretched using any native and
transparent fabric extension technology, such as long-range optics and DWDM. SAN extension
using other intermediate protocols, like IP, is not supported in campus cluster configurations.
To set up the campus cluster functionality, create a multi-site cluster by assigning storage nodes to
sites. For more information on how to configure multi-site clusters and how to work with sites, see
the HP StoreVirtual documentation. Note that server connections, which are assigned to sites in
the management group and are configured for volume access via Fibre Channel, will not honor
the site preference. All multi-site cluster best practices apply.
All Fibre Channel ports of HP StoreVirtual 4000 Storage must be visible to servers connecting via
Fibre Channel to ensure connectivity in case of port, node, or site failures. For more information,
see “Zoning” (page 220).
If Fibre Channel connectivity is used to access volumes on another cluster in the same management
group, the other cluster must have an identical site configuration.
Heterogeneous SAN support
HP StoreVirtual 4000 Storage supports shared access with the operating system combinations
listed in the configuration sets on SPOCK. At the time of this writing, any combinations with Microsoft
Windows Server 2008 and later, and VMware vSphere 4 and later, is supported.
For more details on Fibre Channel HBA and switch support, see HP StoreVirtual 4000 Storage
Configuration Sets available on SPOCK at http://www.hp.com/storage/spock. You must sign up
for an HP Passport to enable access.
Configuration rules
Table 108 (page 219) describes HP StoreVirtual 4000 storage system SAN configuration rules.
Table 108 Heterogeneous SAN storage with Fibre Channel on HP StoreVirtual 4000 Storage rules
DescriptionRule number
Fibre Channel on HP StoreVirtual 4000 Storage is supported in all Fibre Channel SAN fabric
topology configurations described in this guide. This requires unique domain IDs in the entire Fibre
1
Channel SAN to which the StoreVirtual storage system is connected, including multiple independent
fabrics. Overlapping domain IDs (even in non-merged/independent fabrics) are not supported.
Fibre Channel on HP StoreVirtual 4000 Storage can be configured in a SAN using the Fibre
Channel switch models listed in the HP StoreVirtual 4000 Storage sets available on SPOCK at
http://www.hp.com/storage/spock. You must sign up for an HP Passport to enable access.
2
All Fibre Channel ports in a HP StoreVirtual 4000 Storage management group must be zoned to
an HBA port of the server. The resulting zone has the HBA port of the server and all Fibre Channel
port of the HP StoreVirtual management group on the fabric as members.
3
Overlapping storage port zones are supported.4
For information about shared access and heterogeneous platform zoning requirements,
see“Heterogeneous SAN storage system coexistence” (page 208).
5
A single server’s HBAs are supported for common access to other storage systems families as long
as the HBAs are from the same vendor. See “Zoning” (page 220).
6
To enable or disable volume or snapshot access to specific hosts, use the “Assign/unassign volumes
and snapshots” functionality in the Centralized Management Console. For more information, see
the HP StoreVirtual 4000 documentation.
7
Servers that share access to the same storage LUN require special application software (such as
cluster software) to preserve data integrity.
