Use the HPC iSCSI Provider

Microsoft supports iSCSI storage in its High-Performance Compute Cluster software, HPC Server. iSCSI support allows HPC nodes to

boot from iSCSI volumes, and allows the HPC server to provision those volumes. To enable this support, a vendor-specific HPC iSCSI

Provider is required. This version of the Host Integration Tools includes this provider.

About the HPC iSCSI Provider Installation

The HPC iSCSI Provider is installed automatically with the rest of the Host Integration Tools. If you are building an HPC server, you should

install the HPC server package first, followed by the Host Integration Tools. During installation, the Host Integration Tools register the

iSCSI Provider with the HPC server, enabling the HPC server’s iSCSI provisioning.

If you uninstall and then reinstall the HPC server, you will need to reinstall the Host Integration Tools so it can re-register with the HPC

Server.

Configure the PS Series Array

In order to use the HPC iSCSI Provider, you will need to enable access to the VDS/VSS Control Volume on your PS Series array. The

easiest way to configure access to the VDS/VSS Control Volume is using the Remote Setup Wizard. See

Remote Setup Wizard

for

instructions.

If access to the VDS/VSS Control Volume is not configured, the HPC iSCSI Provider will report errors such as

failed to create

tunnel to group

when attempting to set up volumes for HPC nodes.


The HPC iSCSI Provider has settings that can be changed using a graphical tool,

EqlHPCSettings.exe

. This tool is available from the

Start menu. To launch it, click

Start

→

Programs

→

EqualLogic

→


. If you installed the Host Integration

Tools in a different directory, specify that installation directory when you launch the tool.

The settings for the HPC iSCSI Provider are described in the following table.

Table 15. HPC iSCSI Provider Settings

Setting

Default Value

Description

New Volume Size

80,000 MB

The size of all volumes created by the iSCSI HPC Provider. All HPC

volumes are created thin-provisioned, so they will not occupy this

much space on the group. Changing this value will not affect

existing volumes already created by HPC.

Pool Name for HPC Volumes

default

The pool in which to create the volumes. This pool must exist on

the PS Series group in use.

Base Volume Provisioning

10%, 80%, 100%

When thin-provisioned volumes are created, they are assigned a

minimum, maximum, and warning level value. The minimum value is

the amount of storage to assign to the volume immediately. As

data is written to the volume, additional storage will be assigned to

it as needed. If the assigned storage reaches the warning level, the

PS Series group will issue an alert. When the assigned storage

reaches the maximum value, no further storage can be assigned to
