High-availability SAN
• Requires dual-redundant SAN fabrics (level 4, NSPOF high-availability SAN configuration;
see “
Data availability ” on page 53 for information about data availability levels). Each fabric
consists of either a single switch or two cascaded switches, as shown in Figure 58 through
Figure 65 .
• A single fabric supports a maximum of three switches.
• Requires separate fabric zones. Each zone consists of the set of NonStop host (FCSA, Fibre
Channel PIC, or CLIM) WWNs and XP storage system port WWNs to be accessed from a
single NonStop system.
• Configure WWN-based zoning only.
• Only NonStop homogeneous connections are allowed to the same zone.
• Heterogeneous operating systems can share the same switch or SAN, if they are in different
zones.
• HP recommends host-based mirroring. For example, each LDEV (P) is mirrored to a separate
LDEV (M) on separate XP ports (p, b, m, mb paths are used). A nonmirrored volume is allowed.
For example, each LDEV (P) is not mirrored to a separate LDEV (M) on separate XP ports (only
p and b paths are used).
• For high availability, primary (P) LDEVs and mirror (M) LDEVs must be configured on separate
array ACP pairs.
• For high availability, the p and b paths must be in separate XP array clusters. The m and mb
paths must be in separate array clusters.
• HP recommends that the p and mb paths be in the same XP array cluster, and the b and m
paths be together in the other XP array cluster for a volume.
• FCSAs (IOAMEs), Fibre Channel PICs (VIOs), FC HBAs (CLIMs), C-series switches, and B-series
switches are supported with 1 Gb/2 Gb CHIPs for the
XP128/1024/10000/12000/20000/24000 and with 4 Gb CHIPs for the
XP10000/12000/20000/24000.
