Bridgestor Crunch for Data Protection Manager Part 1

 

This post will cover the basics getting the integration up and running further post will cover the integration deeper , the CRUNCH setup of the jobs handling the deduplication and tape rotation is for a later part

 

BridgeStor is trying solve a few of the major pains with Data Protection Manager.

 

Snapshot limit

Data Protection Manager uses VSS for file based workloads limiting snapshots to 64 for short term backups , so if you want to keep more than 64 snapshots you need to setup additional DPM server to protect the first one unless you go to tape.

Storage Allocation

Data Protection manager uses a lot of storage there is no support for deduplication so there is a large need for spindles

So how does BridgeStor solve this

Bridgestor have released their Crunch for Data Protection Manager http://bridgestor.com/English/Solutions/Microsoft_DPM_2012.html

BridgeSTOR DPM

Picture and Spec from http://bridgestor.com/English/Products/CRUNCH_for_DPM.html

Scale

A single CRUNCH for DPM Virtual Appliance can manage 12 “containers” of physical storage capacity, each of which can be up to 4 TB in size (total of 48 TB of physical capacity).

The Crunch is a virtual appliance installed on Hyper-V , its running CentOS and is presenting itself as a tape drive enabling support for both DPM 2010 and 2012.

Create a new VM

image

For testing 8 gig should be “enough” recommended is 32 gig for production or 8 gig combined with a SSD for deduplication work

image

Add the Crunch VHD provided from bridgestore as the boot volume

image

For testing I added just one scsi drive for storage, from a support point of view passthough disk are the only supported option

 

image

Start the VM and enter the menu

image

Enter the Crunch Configuration

 

image

Setup networking

image

and initialize storage

image

after initial configuration boot to crunch

image

and the Crunch Appliance is now ready for action

image

First step is to configure the Virtual Tape , according the documentation it should be a little larger than the biggest protection group in DPM , again this if the first test so a part2 of the post will adjust findings.

and setup a container for storing the data

 

image

On the DPM server start the iscsi initiator

image

and connect to the bridgestore appliance

image

This will present itself as a HP tape drive , the drive needs to be downloaded from HP as its not part of the trial from bridgestor

image

Download the HP Storage Tape Drivers

image

And install

image

And we now have a driver for the crunch device

image

Setup a protection group

image

And just a simple recovery goal

image

And start the long term job

next is the CRUNCH magic.
