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
