Designing a Virtual SAN with HP LeftHand P4000 VSA

Designing a virtual SAN

 

The HP LeftHand P4000 VSA enables full featured use of the SAN/iQ software in a virtualized environment. When deployed correctly, HP LeftHand Networks virtual SANs are scalable, highly available, and fully redundant

 

Designing your virtual SAN

The design of your virtual SAN affects both its performance and its reliability for production use. Use the concepts and practices in this manual when installing and managing your virtual SAN to ensure optimal performance and reliability.

 

 

Download VSA

Transfer the virtual machine to the ESX Server.

Add the VSA to inventory.

Select the network.

Configure the data disk(s).

Reserve the CPU and memory.

Power on the VSA.

Set the IP address and host name of the VSA.

 

 

 

Add VSA to inventory

 

Using the VI Client:

1. In the Inventory Panel, select the VMware ESX Server.

2. In the Information Panel, select the Configuration Tab.

3. In the Hardware section, select Storage (SCSI, SAN, and NFS).

4. In the Storage section, right-click the datastore icon and select Browse Datastore.

5. In the Datastore Browser, right-click the VSA.vmx file and select Add to Inventory.

6. In the Add to Inventory Wizard, enter a name for the new VSA and click Next.

7. Select the Resource Pool to run the VSA and click Next.

8. Verify the information and click Finish.

9. Close the DataStore Browser.

 

Select a network connection

 

1. In the Inventory Panel select the VSA.

2. In the Information Panel select Edit Settings in the Commands section.

3. On Virtual Machine Properties window, select the Hardware tab and select Network Adapter 1.

4. Select the appropriate network connection from the Network label list on the right side.

 

 

Configure a data disk

 

1. Next, click Add at the bottom of the Hardware tab.

2. Select Hard Disk as the type of device you want to add and click Next.

3. Select Create a new virtual disk and click Next.

4. In the Disk Capacity section, designate a capacity that is suitable for the amount of storage available on your ESX Server.

5. In the Location section, select Store with Virtual Machine, and click Next.

6. For the first disk, select the Virtual Device Node to be SCSI 1:0 from the drop-down menu. For additional disks, assign SCSI 1:1 through 1:4, in sequential order.

 

CAUTION:

Selecting anything other than SCSI 1:0 for the first disk causes RAID to be unconfigurable later.

7. Select Mode > Independent > Persistent and click Next.

8. Review the device configuration and click Finish to complete the Add Hardware wizard.

9. Click the Resources tab on the Virtual Machine Properties window.

10. Select CPU and reserve at least 2000 MHz.

11. Select Memory and reserve the appropriate amount of physical memory for the disk capacity,

 

 

 

Pre installation requirements for HP LeftHand Storage Solution, Add HD to ESX and vdisk to VSA

 

At ESX server attach additional HD’s

 

Configuration -->Storage-->Add Storage--> Basic/LUN and select available HD

Name the database (VSA01,VSA02 ..) (Storage name)

Repeat for the second HD

 

 

 

 

Add Disks to Virtual Storage Server VSA and store this new created virtual disk to the new added HD’s (Storage)

VSA --> Edit Setting -->Hardware --> Add –Hard disk -->Select Specify a data store --> Select new created Storage VSA01 --> select SCSI (1:0)

 

Check “Independent” (Independent disk not effected by snapshots)

Select “Persistent (Changes are immediately and permanently written to the disk)

 

 

  

 

 

  

Configuring the VSA for use with the HP LeftHand Storage Solution

 

Power VSA on and Select the Console Tab and wait for the VSA to boot.

 

After the VSA boots up, log in and use the SAN/iQ Configuration Interface to configure an IP address and host name for the VSA.

 

 

 

 

 

Installing the HP LeftHand Centralized Management Console

 

Install the CMC on the computer or virtual machine that you use to administer the VSA. You administer the entire network of VSAs from this CMC.

To obtain the latest CMC for the VSA, go to

http://resources.lefthandnetworks.com/forms/Email-VSA-Download.

 

 

After installation completed, Double click “HP LeftHand Centralized Management Console” to start the console

 

VSA à storage (You can see attached HD)

Centralized Management Console, Add Management Group

 

VSA --> right click --> Add New Management Groups

 

Management Group name VMugGroup

 

Type Administrator user name/password and set the Time

 

In this Lab we are going to select Standard Cluster Type and name the cluster

 

Assign Virtual IP’s and Subnet mask for fault tolerance

 

Now we are ready to create volume, set replication level and size

Attach iSCSI SAN to ESX Server

 

HI am going to attach iSCSI virtual SAN to ESX server and configure adapter

 

This will done at ESX server

 

ESX --> Storage Adapter --> configuration -->iSCSI Software Adapter --> Properties --> General --> configuration -->check “enable” for the Status --> O.K

 

Configure--> iSCSI Name (Copy)

 

Dynamic Discovery --> Add --> ISCSI Server (Type Server IP Address)

 

 

Adding Server to Management Group ( iSCSI SAN )

 

This part should be done on vSAN using CMC

 

VMugGroup -->Server -->NewServer àName (ESX40)

 

Select “CHAP not required”, paste initiator Node name and click O.K.

 

Assign Volume to server at iSCSI SAN

 

 

VMugGroup --> Cluster -->Volumes and snapshots

 

Right click the volume that you want to assign and click “Assign and Unassign Servers”

 

Check Assigned and Read/Write

 

To check this step

 

VMugGroup --> Server --> ESX40 --> Volumes and snapshots (You can see Volume_01 assigned)

 

 

 

 

Add LUN and Create Datastore at ESX Server

 

 

The following steps should be done on ESX server;

 

 

I am going to assign the new volume at vSAN as a datastore for ESX server

 

 

ESX40—Storage Adapters –iSCSI Software Adapter (ReScan)

 

Esx40 --> configuration -->Storage --> Add storage --> Disk/LUN -->Next  -->Select the LUN to create Datastore -->Type Datastore name
