globalSAN Portal ScreenĪt the dialog box, type in the IP address of your iSCSI target and the port number, which defaults to 3260 for a majority of the products you may use. Click on the add icon (+) to add your first portal. Each share will have a unique IP and be referenced as a portal. If you click on the globalSAN System Preference you’ll be able to add your first portal. Once you are logged back in, open System Preferences and you’ll see the new System Preference for globalSAN iSCSI. Here, click on Restart and then log back into the system when it comes back online. Provided everything installs properly you will next be at the Installation Completed Successfully screen. It is best to leave them all checked and then click on the Continue button. globalSAN Uninstall ScreenĪt the Standard Install screen you can click on the Custom Install button to allow you to choose which packages within the metapackage to install.

So for starters, fire up your iSCSI storage and share it out. However, we’ve also tested LeftHand, Isilon, OpenFiler, iSCSI Target (from Microsoft) and many others (including dozens of appliances) with the Mac. For the purpose of this article we’re going to use the SNS globalSAN software.įor the purposes of this howto, we’re using the free version of software called Starwind from RocketDivision. Software based initiators will use the CPU of your system and a built-in or third party standard Ethernet port, but you can also buy a dedicated card which will offload the processing power to the card, which in some cases will be required for various performance reasons. Alternatively you can also look into the Atto Xtend SAN, which runs about $200 for 1 user with volumes discount slashing the prices to about $90 for 100 users. Studio Network Solutions (SNS) provides a software-based iSCSI initiator called globalSAN that can be downloaded and used free of charge from their site. As with Xsan, to get started with iSCSI you’ll need an initiator and a target. Recently, I’ve recently been seeing a lot of traffic about whether or not you can use iSCSI with Mac OS X. While you can use pretty much any Ethernet switch, I’d recommend that if you’re going to use iSCSI that you dedicate a switch to it, or use quality switches and build a dedicated VLAN for your iSCSI traffic. This allows you to leverage Ethernet, a low cost network medium to get SAN performance and network based storage. This is done to ensure the most amount of VMs are backed up instead of just one very large VM. The calculation is done using the gross disk size total of all the HDs associated with the VM.ISCSI is a network storage protocol that allows sending and receiving of SCSI commands over a TCP/IP network. The location of SendEmail - If you have opted to enable Email, you need to input where you have extracted the perl executable here.Įmail details - Again, if you have enabled email, you need to define details such as: To, From, Servername/IP & etc'.Ĭompression - This is set to "No" by default, because while enabling it will produce a smaller backup file, it will also cause the backup procedure to run for a considerably longer amount of time.Ĭheck for free space on the destination - This will have the script check that making the VM's backup will not cause the backup location's free space to fall beneath 10GB. The location of the backup destination - If you have followed the guide to this point, you only have to replace the %UUID% with the SR's as it was obtained from above. You may change this to FILE, but this is not recommended. The method for obtaining the VMs to be backed up - The default method is TAGs.
