Single HP VMA SAN Gateway with 1–2
HP VMA-series Memory Arrays, Non Redundant
Figure 1.1
shows a configuration of a single VMA-series SAN Gateway is directly connected to a
group of up to two HP VMA-series Memory Arrays using PCIe cables. The HP VMA SAN
Gateway must be connected to Port 1 on each Memory Array in x8 mode.
Note:
In the vSHARE software,
Port A
refers to the port that is labeled
Port 1
on HP VMA-series
Memory Arrays.
Port B
refers to the port that is labeled
Port 2
.
Redundant Pair of VMA-series SAN Gateways with 1–2
HP VMA-series Memory Arrays, Highly Available
Figure 1.2
shows the most common configuration, a High Availability (HA) pair of VMA-series
SAN Gateways that provide redundant access to a group of up to two HP VMA-series Memory
Arrays.
In the example, SAN Gateway 1 is connected to Port A on each Memory Array, and SAN Gateway
2 is connected to Port B on each Memory Array. It is important that the Memory Gateways are
cabled to the Memory Arrays using identical slots for HA pairs. That is, if PCIe Slot 1 on SAN
