2015 HA-AP Deployment -- Part 3 of
4 Although
the HA-AP solution is extremely flexible and adaptive to any IT
environment, there are basic deployment concepts and models to follow.
They are summarized as below: · Key Deployment Concepts · The Simplicity Solution Deployment Model · The Duality Solution Deployment Model · The Infinity Soluton Deployment Model Review:
Key HA-AP Deployment Concepts In its most basic
deployment case, a single dual-engine (HA-AP Engine, HAE) appliance is
installed between a small set of servers and a pair of RAID5 arrays, as
shown in Figure 1. This provides a storage configuration with high
data-delivery performance and instantaneous failover capabilities. To
the storage, the Engine appears as the SCSI initiator. To the host, the
Engine appears as the SCSI target. Servers perceive a cluster of Engine
modules as a multi-port, active-active storage system.
The Duality Solution Deployment Model
The Duality solution is an HA SAN solution enabled by HA-AP for constructing a high-availability storage infrastructure within a dual-active datacentre. A 4-engine cluster with extended FC fabric by ISL connections between switches (refer to Figure 3) is recommended for dual-site configurations.
