1System requirements

□ Installation requirements

□ Considerations when using a virtual SMU

□ Memory and CPU resource allocations

System requirements 9Virtual SMU Administration Guide for Hitachi NAS Platform and Hitachi Virtual Storage Platform Gx00 and Fx00 with

NAS Modules

Installation requirementsBefore you install the virtual System Management Unit (SMU), check thatyour system meets all of the requirements for new installations.

The minimum virtual SMU resource requirements are stated below. Thephysical hardware should exceed these minimum requirements so that thehost has resources beyond those allocated to the virtual SMU. In particular,the host should have more physical RAM than is allocated to the virtual SMU.

• Minimum virtual SMU specifications:○ 64-bit CPU with at least 2 CPU cores (1 CPU core per managed server or

cluster recommended).○ 2 GB RAM (1 GB per managed server or cluster recommended).○ 100 GiB hard drive space.○ 1 GigE network adapter.

• IP addresses for access to a VMware vSphere® Hypervisor installation, ifapplicable, and for connecting to the SMU. Note that each SMU virtualmachine (VM) you deploy requires at least one IP address for managementUI access.

• An SMU OS install package.• An SMU software install image.

Note: The VMware vSphere Hypervisor tool is free and permanently licensed.For more information, go to: http://www.vmware.com/products/vsphere-hypervisor.

If you have any questions, please contact your support organizations forassistance with these products.

Considerations when using a virtual SMUBefore you install and configure the virtual SMU, consider the following:

• A minimum amount of resources must be reserved for each VM. VMwareallows the VM to start only if resources can be guaranteed. For moreinformation, see Memory and CPU resource allocations on page 11.

• Virtual SMU software version 12.5.4038.04 or later supports up to 10managed servers or clusters. Earlier SMU software versions support up totwo managed servers or clusters.

• Open virtual appliance/application (OVA) is the standard distributionformat for the virtual SMU. An OVA is a compressed archive (tarball) ofOpen Virtualization Format (OVF) files, including configuration and sparsedisk image files.

10 System requirementsVirtual SMU Administration Guide for Hitachi NAS Platform and Hitachi Virtual Storage Platform Gx00 and Fx00 with

NAS Modules

http://www.vmware.com/products/vsphere-hypervisor

http://www.vmware.com/products/vsphere-hypervisor

Memory and CPU resource allocationsIn SMU software version 12.5.4038.04 or later, the virtual SMU supports upto 10 managed servers or clusters if the SMU software is set up correctly.

The virtual SMU should be allocated 1 GB RAM and 1 CPU core per managedserver or cluster, regardless of the number of nodes in a cluster. For example,to manage four HNAS clusters, the virtual SMU should be allocated 4 GB RAMand 4 CPU cores. The virtual SMU’s minimum requirement is 2 GB RAM and 2CPU cores, which is the default when it is deployed.

Sufficient memory and CPU resources allocated to the virtual SMU ensurethat:• The SMU's quorum device has enough priority on an oversubscribed host

to maintain real-time communication with an HNAS cluster.• Sufficient resources are available for background monitoring, which the

SMU performs for each managed server cluster.

Important: The quorum device must respond to cluster heartbeats (overUDP) within five seconds to prevent the possibility of dependent anddegraded HNAS clusters rebooting. Make sure that the SMU VM always hassufficient resources so that the quorum device is not paused or unresponsivefor more than five seconds.

Resource reservations are less important when the SMU is not used as aquorum device.

Note: The NAS module uses a different mechanism to control high-availability, so it does not use the SMU's quorum device.

Installing and configuring a virtual SMU 13Virtual SMU Administration Guide for Hitachi NAS Platform and Hitachi Virtual Storage Platform Gx00 and Fx00 with

NAS Modules

Installing the vSphere ESXi hostIf the vSphere ESXi™ host is not already installed and operational, install thevSphere ESXi host onto the bare-metal host machine for your VM.

Note: The vSphere ESXi host must be version 5.1 or later.

Before you begin

Make sure that you have the ESXi ISO installer image on one of thefollowing:• USB flash drive• CD or DVD

The following example uses a bootable USB flash drive to install the ESXi ISOimage file.

Procedure

1. Navigate to the server BIOS and verify that the USB flash drive is thefirst device in the boot order. For information about how to change theboot order, see the documentation provided with your server hardware.

2. Plug the USB drive into an available USB port.3. Power on the bare-metal host machine.

The system boots to the USB drive.4. When prompted, select the ESXi ISO image file.5. When the welcome screen appears, press Enter to start the installation.

6. To accept the End User License Agreement, press F11.7. Select a disk on which to install the ESXi host, and then press Enter.

14 Installing and configuring a virtual SMUVirtual SMU Administration Guide for Hitachi NAS Platform and Hitachi Virtual Storage Platform Gx00 and Fx00 with

NAS Modules

8. Select your preferred keyboard layout, and then press Enter.9. Type a root password for the account, and then press Enter. Note that

the root password must have a minimum of seven characters.

Note: If you see a warning that the CPU does not have HardwareVirtualization enabled, press Enter to continue. You will need gointo the BIOS later to enable Hardware Virtualization.

10. To start the ESXi installation, press F11.11. When the installation is complete, remove the USB drive, and then press

Enter to reboot the server.

Next steps

When the server has rebooted, you will need an IP address to install thevSphere Client. Either use the IP address on the ESXi home screen (if DHCPis enabled), or set up a static management IP address (recommended).

Setting a static IP addressSet up a unique static management IP address for managing the vSpherehost with the vSphere Client.

Procedure

1. On the ESXi home screen, press F2.


NAS Modules

2. Type the login name root and the root password, and then press Enter.3. Select Configure Management Network > IP Configuration, and

then press Enter.4. Select Set Static IP IP address and network configuration, and

then press Enter.5. Type the following static IP configuration in the corresponding text boxes,

and then press Enter.• IP Address: The static IP address for the ESXi host.• Subnet Mask: The subnet mask of the network to which the static IP

address belongs.• Default Gateway: The gateway for the subnet.

6. Press Esc to return to the main menu.7. In the Configure Management Network: Confirm dialog box, select

Yes to apply your changes and restart the management network.ESXi configures the management network with the new static IP address.


NAS Modules

Installing the vSphere ClientYou use the vSphere Client to connect to and manage the vSphere ESXi host,and to operate its virtual machines.

Procedure

1. On your laptop or desktop, open a web browser and point it to thevSphere host management network IP address (as configured after thevSphere ESXi host installation).

2. On the welcome screen, click Download vSphere Client, and then clickSave File.

3. When the download is complete, navigate to the location of the

downloaded installer file.4. Double-click the installer file to open the vSphere Client installation

wizard.5. Click Next, follow the prompts, and then click Install.6. When the installation is complete, click Finish.7. Navigate to the location of the vSphere Client file, and then open it.8. In the VMware vSphere Client dialog box, type the user name root

and the root password, and then click Login.


NAS Modules

You can now manage the vSphere host with the vSphere Client.

Deploying the SMU OSDeploy and map the pre-configured SMU OVA template.

Note: If you are using SMU software version 12.5.4038.04 or later, and theSMU OVA 2.2 file, eth0 is the default network adapter and eth1 is optional.

Procedure

1. In the vSphere Client, click File > Deploy OVF Template to start thedeployment wizard.

2. Click Browse, and then locate the SMU OS OVA file.3. Click Next to select the defaults, and then type your desired SMU name.4. In the disk format dialog box, select Thin Provision.

Note that you can select Thick Provision if you want to guarantee thatthe host will immediately allocate sufficient disk space, or if the virtualSMU will be used with features that require thick provisioning, such asVMware vSphere Fault Tolerance. You can also manually "inflate" a thinlyprovisioned disk if required.


NAS Modules

5. Click Finish to deploy the OVA. Note that this process may take a few

moments to complete.

Increasing memory and CPU resource allocationsBefore you add extra managed servers or clusters to the virtual SMU,increase the memory and the CPU resource allocations to reserve sufficientresources for each VM.

The following example is for four managed servers.

Procedure

1. Power off the VM.2. In the vSphere Client, right-click the VM and select Edit Settings to

open the Virtual Machine Properties dialog box.a. Under Hardware, select Memory.b. In the Memory Size box, increase the memory to 4 GB.c. Under Hardware, select CPUs.d. Change either the Number of virtual sockets or the Number of

virtual cores per socket so that the Total number of cores is 4.


NAS Modules

3. (Best practice*) Click the Resources tab.

a. Under Settings, select Memory.b. Under Resource Allocation, set Reservation to 4096 MB, and then

click OK.c. (Optional) Although CPU reservation is not required, you should

increase the CPU reservation if the host supports it.d. (Optional) If other VMs on the host could starve the virtual SMU of

resources, under the Resources tab you can set Shares for CPU,Memory, and Disk to High. This prioritizes the virtual SMU over VMswith a Normal or Low setting.

4. Click OK to save your changes, and then close the dialog box.5. Right-click the VM and select Edit Settings again to verify that your

memory and CPU settings are correct.

*Best practice

Although resource reservations are not required, it is best to reserve aportion of the host's physical RAM to guarantee the responsiveness of thevirtual SMU and its quorum device. Ultimately, if you oversubscribe the host,do so responsibly to ensure that the virtual SMU is not starved of resources.

The critical virtual SMU requirement is that the quorum device mustrespond to cluster heartbeats (over UDP) within five seconds toprevent the possibility of dependent and degraded HNAS clusters rebooting.Resource reservations are just one way of achieving this requirement.VMware also provides other mechanisms to ensure VM responsiveness andto protect against resource starvation.


NAS Modules

Installing the SMU software in a VMThe SMU software is a virtual solution that runs on the vSphere ESXi server.After you install the SMU OVA template, set up and connect the SMUsoftware image to the newly created guest virtual machine.

7. To change the directory to vmware-tools-distrib and then run theinstaller, type:cd vmware-tools-distrib./vmware-install.pl

8. Follow the prompts and confirm the default settings.9. When the script is complete, type reboot.

10. To confirm that VMware Tools has installed, click the VM Summary tab.


NAS Modules

Adding an optional eth1If you are using SMU software version 12.5.4038.04 or later, and the SMUOVA 2.2 file, you can add an optional eth1 in addition to the default singleeth0.

In general, SMUs need only a single Network Interface Card (NIC). Add asecond NIC only if there a clear requirement for it.

Before you begin

• Make sure that a vSwitch is configured. For more information, see Configuring virtual switches on page 26.

• Note that the optional eth1 does not apply to embedded SMUs.

Procedure

1. Power off the VM.2. In the vSphere Client, right-click the VM and select Edit Settings to

open the Virtual Machine Properties dialog box.3. On the Hardware tab, click Add.4. Select Ethernet Adapter, and then click Next.5. Under Adapter Type, from the Type list, select E1000.

6. Under Network Connection, from the Network label list, select

Private network eth1, and then click Finish.


NAS Modules

Configuring virtual switchesIn SMU software version 12.5.4038.04 or later, the virtual SMU requires onlyone NIC. If you are using only eth0, skip the following vSwitch configuration.

If you require a private network, configure a virtual switch (vSwitch) to avoidplacing the private network for the SMU onto the public NIC. The secondnetwork adaptor to be used for the private network should reside in aseparate vSwitch.

Procedure

1. In the vSphere Client, click the Configuration tab.2. In the Hardware pane, select Networking.

3. Click Add Networking to start the wizard.4. Select the Virtual Machine default for the Connection Type, and then
