EXECUTIVE SUMMARY VMware ® ESX Server is virtual infrastructure software for consolidating and managing systems. ESX Server accelerates service deployments and adds management flexibility by partitioning x86 servers into a pool of secure, portable and hardware-independent virtual machines.
AUDIENCE Information contained in this white paper is intended for Iomega customers, partners, and service personnel involved in planning, architecting, or administering a VMware environment with an Iomega StorC enter NAS as the storage device.
SOFTWARE T able 2 lists the software resources used in the testing environment. DEPLOYMENT ROADMAP F ollowing its installation and initial configuration, the ESX Server can be connected to shared storage that is presented from the StorC enter ix4-200r over the NFS and the iSCSI network protocols.
w C reating VMFS datastores in the ESX Server – for iSCSI, configuring VMFS datastores over the iSCSI LUNs that were provisioned from a StorC enter ix4-200r . w Adding RDM disks to virtual machines – for iSCSI, alternatively making the LUNs available as RDM disks to the virtual machines.
White Paper 6 2. Select the VMkernel connection type as shown in Figure 3. Figure 3 VMkernel selection 3. Select a virtual switch to handle the VMkernel port traffic Figure 4 Select virtual switch STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
White Paper 7 4. Name the new VMkernel port group and optionally the VLAN ID for the network. Figure 5 Name the VMkernel port group 5. V erify the settings and finish creating the VMkernel port. Figure 6 VMkernel port group created STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
White Paper 8 ADDING A SHARE ON AN IOMEGA STORCENTER NAS DEVICE When using NFS storage, you need to add a share on a StorC enter ix4-200r . Appropriate access permissions must be set for the VMkernel port on the ESX Server to mount an NFS share. These access permissions are: w Host access – provide the VMkernel port mount access to the share.
White Paper 9 2. Go to Shared Storage and click Add to create a new share and optionally enable security on it. Figure 8 Create a new share When creating the share, ensure F older is the shared storage type and that Enable security is not checked. 3. Click Next to specify user access to the secured share.
White Paper 10 STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.5 4. Click Next to specify host access to the secured share. Make sure you enter the IP address of the VMKernel port created previously , not the service console port. Figure 10 Specify host access 5.
White Paper 11 CREA TING AN NFS DA T ASTORE ON ESX SERVER VMware Infrastructure 3 management utilities are used to configure and mount NFS shares from the StorC enter ix4- 200r .
White Paper 12 The TCP/IP heap is memory used for TCP/IP buffers for NFS, iSCSI, VMotion, etc. The default NFS.SendBufferSize is 264KB, and the default NFS.ReceiveBufferSize is 128KB. So with two sockets per volume, the total heap needed per volume is 784KB.
White Paper 13 1. Go to C onfiguration > Storage > Add Storage … Figure 14 Add storage to ESX Server 2. Select the Network File System option. Figure 15 Select NFS type STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
White Paper 14 3. Enter the NFS server and share information on StorC enter ix4-200r . Figure 16 Mount the NFS share Either the hostname or the IP address of the StorC enter ix4-200r can be entered here. Ensure that “/nfs” is specified in the folder path so Lifeline can export an NFS share.
White Paper 15 ADDING AN ISCSI LUN ON AN IOMEGA STORCENTER NAS DEVICE When using iSCSI storage, you need to add an iSCSI LUN on a StorC enter ix4-200r . A total of 32 iSCSI targets can be created on an StorC enter ix4-200r , with each target holding one single LUN.
White Paper 16 2. Click Shared Storage and click Add to create a new iSCSI LUN and enable security on it. Figure 19 Add new LUN 3. Proceed to set user access to the LUN. Figure 20 Set user access to the LUN STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
White Paper 17 In this example, the user account Administrator is given read/write access to the LUN, but other users have no access to it. This Administrator user account and its password will be the CHAP logon credentials to be used by ESX Server . 4.
White Paper 18 1. Enable the iSCSI client in the VMware ESX firewall. Go to C onfiguration > Security Profile > Properties … Figure 22 Enable iSCSI client 2. Click C onfiguration > Storage Adapters Figure 23 iSCSI Software Adapter STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
White Paper 19 3. Click the vmnba32 iSCSI software adapter and then click Properties . If the iSCSI initiator is not enabled yet, click C onfigure to enable the initiator and use the default iSCSI name. Figure 24 iSCSI initiator properties 4. Click Dynamic Discovery > Add to enter the iSCSI server information.
White Paper 20 5. Click CHAP Authentication > C onfigure to enter the CHAP authentication credentials for logon to the iSCSI targets on the StorC enter ix4-200r . The CHAP name should be the user name that is granted read/write access to an iSCSI LUN.
All the targets and LUNs that are either unsecured or granted access to the Administrator user will show up as disks in the VMware ESX. 7. Go to C onfiguration > Storage > Add Storage … again to create VMFS datastore. 8. Select the Disk/LUN option.
White Paper 22 10. Review the current disk layout on the disk and proceed Figure 30 Review disk layout 11. Name the VMFS datastore to be created. Again, give it a meaningful name so it can be easily identified Figure 31 Name the VMFS datastore STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
White Paper 23 12. Specify the maximum file size allowed on the datastore and the maximum capacity on the datastore Figure 32 Specify file size and capacity 13. Review the summary and proceed to create the VMFS datastore. Figure 33 Create VMFS datastore STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
White Paper 24 ADDING AN RDM DISK TO VIRTUAL MACHINE A raw device mapping (RDM) is a special file in a VMFS volume that acts as a proxy for a raw device. The RDM provides some of the advantages of a virtual disk in the VMFS file system, while keeping some advantages of direct access to raw devices.
4. Go to Summary > Edit Settings with the virtual machine powered on or powered off. When in the Virtual Machine Properties window , click Add to add a new hardware to the virtual machine. Figure 35 Edit virtual machine settings 5. Select Hard Disk as the hardware to add.
White Paper 26 STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.5 6. Choose Raw Device Mappings as the virtual disk type. Figure 37 Select RDM as the disk type 7.
8. Choose which datastore to map to the RDM. The default is to store the RDM with the virtual machine in the same datastore. Figure 39 Decide where to map the RDM 9. Select which RDM compatibility mode to use. Figure 40 Select the compatibility mode White Paper 27 STORCENTER IX4-200r NAS WITH VMWARE ESX SERVER 3.
10. Choose the default virtual device/SCSI node and have the RDM disk added into the virtual machine. 11. After the RDM disk is added from ESX Server , the virtual machine needs to rescan its SCSI bus to discover the new disk. Afterwards, partitions can be created and formatted with a file system type.
