Dell F-Series manual SAN-Attached Cluster Rules and Guidelines

Page 12

Storage area network (SAN) — A configuration of computer and storage systems that incorporates dedicated Fibre Channel connectivity between the computer systems and storage. A SAN bypasses traditional network bottlenecks and sup- ports direct high-speed data transfer between the servers and storage devices.

SAN-Attached Cluster Rules and Guidelines

The following rules and requirements described in Table 1-1 apply to SAN-attached clusters. For rules and requirements for cluster consolidation configurations, see “Cluster Consolidation Rules and Guidelines” found later in this document. See the Dell PowerVault SAN documentation for more information on general SAN rules and guidelines.

Table 1-1. Rules and Guidelines for SAN-Attached Clusters

Rule/Guideline

Description

 

 

Number of servers

Up to 10 two-node clusters attached to a SAN.

supported

Combinations of standalone servers and cluster pairs

 

not to exceed 20 server maximum.

 

 

Cluster pair support

All homogeneous and heterogeneous PowerEdge

 

Cluster F-Series configurations supported in direct-

 

attach configurations are supported in SAN-attached

 

configurations. See the Dell PowerEdge Cluster FE100/

 

FL100 Platform Guide for more information on sup-

 

ported cluster pairs.

 

 

Primary storage

Up to 8 PowerVault Fibre Channel disk arrays are sup-

 

ported on a SAN. Primary storage can be owned by a

 

single cluster and multiple clusters (through SAN-

 

attached cluster consolidation configurations discussed

 

later in this document). A mixture of these types of

 

ownership on a single storage system is not supported.

 

For example, the following are supported configura-

 

tions: one cluster to one storage system, one cluster to

 

multiple storage systems, and multiple clusters to one

 

storage system. However, a configuration with multiple

 

clusters to multiple storage systems is not supported.

 

A mixture of configurations is supported on a SAN.

 

 

Secondary storage

Up to 4 Fibre Channel Bridges are supported, each with

 

up to 2 PowerVault 130T tape libraries or up to 4 Power-

 

Vault 120T tape autoloaders. Any server attached to the

 

SAN can share these devices.

 

 

Dell OpenManage™

Not required for standard SAN-attached clusters.

Storage

 

Consolidation

 

 

 

Fibre Channel switch

Redundant switch fabrics required for clusters.

configuration

 

 

 

Fibre Channel switch

Required whenever a cluster shares a SAN with other

zoning

cluster(s) or standalone server(s).
