1.0 Objective This Quick Start Guide is intended to give an adm inistrator a quick overview on how to quickly set up a Sun™ Storage 7000 Unified Storage System to use with a VMware ESX Server.
1.2 iSCSI Access The diagram below gives an overview of acc essing the Sun Storage 7000 Unified Storage System using the iSCSI protocol to host Virtual Machine Vi rtual Disks (vmdk). An iSCSI LUN is exported from the Sun Storage 7000 Unified Storage System and attached us ing the vmkernel in the VMware ESX host.
2.0 Configuring Sun Storage 7000 Unified Storage System for VMware ESX 2.1 Security It is recommended that you create a loc al user on the Sun Storage 7000 Unified Storage System that is associated with a role that allows lim ited configuration and control for shares within a specific proj ect dedicated to VMware ESX use.
allow administration rights on the Sun Storage 7000 Unifi ed Storage System; it is not for file system ownership or file creation privileges. The user should al so be associated with the built-in "basic" role a s well as the VMUser_Role configured above.
6. Copy the contents of the . pub file. (Copy only the key itself, not the type field or the comment field.) Paste it in the entry box. Next copy and paste (or type) an optional comment to clearly indicate who the key is for. 7. Click Apply from the main screen t o complete the procedure.

Interface Configuration Example 2.3 Pool Configuring the pool storage RAID layout is a bal ance between availability, capacity and pe rformance. As can be seen during pool configuration, the Sun Storage 7000 Unified Storage System BUI gives a description plus the relative tradeoffs a round availability, capacity and performance.
project level. If you have differing replica tion schedules for different types of virtual mac hines (or even subsets of virtual disk types, OS/boot versus production data) you should configure multiple projects, each to replicate on their own schedule.
6. Click the Edit icon next to Shar e to change any of the defaults. By default, all Sun Storage 7000 Unified Storage System fi lesystems are created under /export/ sharenam e m ount points. This can be overridden at the project or share le vel if needed.
The initiator access can also be c onfigured at the project level if all LUNs in a proj ect are going to have the same initiator access. 2.5 Analytics The following analytics are useful to observe t h.
3.0 Configuring VMware ESX With Sun S torage 7000 Unified Storage System 3.1 Changing NFS Settings in VMw are ESX By default, VMware ESX has an NFS datastore l imit of eight file systems. To change that limit , use the following steps: 1. Log in to Virtual Center.
3.3 iSCSI Access To enable the built-in VMware ESX iSCSI soft ware initiator: 1. Log in to Virtual Center. 2. Select Configuration -> Storage Adapters . 3. Select the iSCSI Software Adapter . Cli ck Properties . 4. Click Configure . Check the En abled box.
5. Select the Dynamic Discovery t ab. 6. Click Add . Enter the IP address of the Sun Storage 7000 Unifie d Storage System. Click OK . 7. Click Close . 8. Click the Rescan link to have VMw are ESX discover the Sun Storage 7000 Unified Storage System iSCSI LUNs.
3.4 Enabling NFSv3 Acces s 1. Log in to Virtual Center. 2. Select Configuration -> Storage - > Add Storage . 3. Choose Network File System . 4. Enter the Sun Storage 7000 Unified Storage System name or IP, fil e system mount point, and a Datastore label.
4.0 Advanced Data Services The following section gives a high-level overview on how to enable snapshots and replication on the Sun Storage 7000 Unified Storage System to use with VMware ESX . It is outside the scope of this document to delve into the lower-level implementation details for snapshot and replica tion.
4.3 Replication Replication is configured at the project level only. All file systems or iSCSI LUNs cont ained within a project will be asynchronously replicat ed on the same schedule to the target system.
5.0 Appendix This appendix contains a sample workflow scri pt to build an Analytics worksheet for monitoring NFSv3 and iSCSI operations. This workflow should be copied to a te xt file and then uploaded to the Sun Storage 7000 Unified Storage System by taking the following steps: 1.
* from the created worksh eet if they so desire. (It would * be strai ghtforwar d to add a boolean parameter to this * workflow that allows that last behavio r to be optionally * changed. ) */ run('analyt ics works heets' ); run('create "' + params.
