Hyper-v 3 (2012) connecting to a SAS Tape Auto Loader

Hi All,

In case its not obvious, I know virtually nothing about Hyper-v.

But having recently bought 2012 Datacenter, I thought I should really give it a go.

I have an HP DL385 and an HP 1/8 G2 LTO-5 Ultrium 3000 SAS Tape Autoloader


Is it possible to connect and use the SAS tape auto loader to a Virtual Server running on Hyper-v


Thanks

You need to get a plain, vanilla SAS JBOD controller specifically for the tape.  LSI has a bunch on the HCL, many can be found on ebay for well under $100.  (LSI 38xx  as example)

How does it handle the passthrough etc?

DavidCommented:
I have no idea how or if hyperv3 can do pass-through like ESX can.  But I do know that the card in the 385 absolutely will not work for a tape, even if you were running vmware, so you are wasting your time even trying with that controller.

That i best I can offer you. So look in the docs to see if you can do direct pass-through in Hyper-V3, like you can in ESX, or hope an expert familiar with Hyperv3 can help with controller pass-through question to get you the rest of the information you need.  Obviously don't buy anything until you have the answer.

I know very little about Hyper-v.

Is there a way to make it show up in the parent hyper visor?

Is it possible to install software on the parent hyper visor?

I would be looking at buying a PCIe or PCI SAS card, are there any recommendations?

How does Hyper-v work?


Is it like ESX, where you install the Hyper Visor and Guest OS.  Or do you Install Windows 2012 and enable it as feature.

As if its the latter can the parent HOST run Backup Exec?


I've not got a SAS card in the server, I'll be buying one.

Look at the MSFT HCL list for SAS JBOD controllers that are approved.  But I would be astounded if they don't support the standard LSI SAS controllers like the 38xx or 34xx family controllers (make sure JBOD) you can get on ebay for $20-50.

You want to make sure it is listed as a JBOD controller or sometimes a HBA.  Do not get one with built-in RAID, like the megaraid or 3ware family.

My knowledge is of hyper-v 2008 r2. You can load backup software such as backup exec in the parent partition. The guests can only access vhd/vhdx virtual drives, passthrough DISKS, or use iSCSI from the guest to storage. Hyper-V 3 added passthrough FC, but I have not heard about passthrough for SAS. I believe that the only way a guest can access tape is via FC or iSCSI, neither of which you have. Load your backup software in the parent and backup from there.

I've never used Hyper-v before.  How does it work.

Can I install a Windows 2008 R2 and enable Hyper v, and use the host (parent) OS to run Backup Exec?

The main thing I am looking for is not to tie up a high powered server to just run the backups.

kevinhsiehCommented:
You would use the same server hardware to run your VMs and do the backups.

Here is a link to the Microsoft page describing all things Hyper-V. To load Hyper-V, you load Windows 2012 on your server hardware, and then enable Hyper-V under Roles.

I though Hyper-v was similar to ESX.  i.e. no parent OS

Sorry, to clarify I can:

*  Install 2008 R2
*  Install Symantec Backup Exec 2010
*  Connect a SAS Tape AutoLoader
*  Configure Backup Exec to use the AutoLoader

Then enable Hyper-v role and the parent OS will still run as normal?


If this is the case, I can use any SAS can, right?

Hyper-v is like ESXi in that it is a type 1 bare metal hypervisor, but you still have a full OS loaded in the parent partition. I suggest that you start by loading Windows 2012 on the server (you bought it, why would you load 2008 R2?), enable Hyper-V, and then load Backup Exec. Yes, the parent will still run as normal.

I think that you want to run virtual machines with hyper-v and think that you are a little confuse about hyper-v and esxi.

Like kevinhsieh says, hyper-v is a role in a windows server.

First you have to install windows 2012 server. * (This is the OS for your physical server and is a full functional Windows Server installation)
Then you have to enable hyper-v, the role that allow you to run virtual machines.
Then you can add and install virtual machines under hyper-v.

After that if you want to backup your virtual machines, then I think that you have to install the hba in the first server Windows 2012 that you install * and install the backup software too in that server. Then you can use the tape and the software in the parent windows server 2012 and backup the virtual machines files with the software.

This way you don't need to install the backup software in a virtual machine, you have it in the parent server.

I'm not sure, but I believe that hyper-v don't support pass-trough like VMware does.

If you want that the tape was used by a virtual machine, maybe you should consider use vmware in place of hyper-v, but maybe you will loss some advantage of your Windows server version.

Thanks that clears a lot of confusion up.
