Deployment Types and Cabling
This chapter will show detailed deployment types and cabling for the XCubeDAS series. You
can start to build up a deployment plan for your XCubeDAS series
in server storage
expansion (DAS or JBOD) or QSAN XCubeSAN series array expansion enclosure.

Deployment Types
XCubeDAS series supports the following deployment types:

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 XCubeDAS 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 XCubeDAS system. In this
deployment, both controllers in the system are used.
Because dual path deployments provide two paths to the
server or array expansion 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 a server attached deployment, the server within an HBA
or a RAID controller card is connected to the XCubeDAS
system. In this deployment, both single and dual path
deployment modes are supported. Several models of
HBAs and RAID controller cards are supported for use with
XCubeDAS series. For more information, please refer to
the
QSAN SAN Array Expansion
Enclosure Attached
(for single or dual controller
models)
In a QSAN SAN array expansion enclosure attached
deployment, the SAN array within the expansion ports is
connected to the XCubeDAS system. In this deployment,
both single and dual path deployment modes are
supported. For more information, please refer to the
