4. Deployment Types and Cabling
This chapter will show detailed deployment types and cabling for the XCubeSAN series. You
can start to build up a deployment plan for your Fibre channel or iSCSI storage environment
by deploying your XCubeSAN systems to your desired host. For expansion you can also
attach the XCubeDAS series RAID expansion enclosures.
4.1. Deployment Types
XCubeSAN series supports following deployment types:
Table 4-1 Deployment Types
Deployment Type Description
Single Path
(for single or dual controller
models)
In a single path deployment, one path is connected from
the host/server to the XCubeSAN system. In this
deployment, only one controller in the enclosure is used.
Dual Path
(for dual controller models) In a dual path deployment, two paths are connected from
the host/server to the XCubeSAN system. In
this
deployment, both controllers in the system are used.
Because dual path deployments provide two paths to the
XCubeSAN system for redundancy even in the event of
device, cable, or power failure. In dual-path deployment
environment, disk drives must support dual paths I/O (SAS
interface).
Server Attached
(for single or dual controller
models) In multi-server attached deployment, more than one server
is connected to the XCubeSAN system. In multi-server
attached deployment, both single and dual path
deployment modes are supported.
