A disaster recovery web site make is a large undertaking, with numerous points of monetary danger that can undermine the project. This create-up discusses approaches that you can decrease price and mitigate danger in your disaster recovery project.
Saving useful datacenter space in your production place could fund 100% of your DR project. Look at moving, upgrading and repurposing improvement, testing or aging production gear from your key web site to DR. This way you can bring in newer technologies to the key place and transition aging IT assets to the DR place. By carrying out so you not only decrease the IT capital expense of your DR project you also free of charge up information center floor space in your production place and give an chance to refresh gear at your key place.
Information Storage Hardware
Information storage hardware is a single of the quickest expanding and most pricey pieces of the DR puzzle. There are two helpful approaches to decrease expenses: 1, take into consideration reconfiguring and repurposing an current IBM, EMC or NetApp array from a production place to DR. Two, take into consideration shopping for a utilized SAN storage array that has been reconfigured to meet your needs. By carrying out so you could save anyplace from $30,000 to $300,000, or far more, based on the configuration.
Connectivity – SAN & Bandwidth
For SAN connectivity, you may well require FCIP routers, SAN directors, switches, HBAs and further networking gear at your new place, coupled with Bluecoat, Riverbed or Cisco WAN acceleration to decrease bandwidth expenses. By shopping for and deploying utilized Cisco MDS or utilized Brocade SAN directors in the web site make, you can save $50,000 to $150,000, leaving you space to get the WAN acceleration solutions and bringing you extended-term, recurring savings on bandwidth.
Transition and Logistics
Moving gear from production to DR can trigger numerous logistical nightmares. As an insurance coverage policy against an unforeseen outage, take into consideration employing Swing or Rental IT hardware, specifically EMC or IBM storage arrays, to migrate information and offset your move. 1 of our clients leveraged this method and rented an EMC storage array for two months. He shipped the array to his production place, migrated the information, then utilized the rental array in production, whilst he shipped their key technique to their new place. This gave them the peace of thoughts and timeframe to move systems at their leisure to DR, and prevent the sort of “rush job” that ordinarily ends in failure.
There are numerous approaches that you can move and guard information amongst datacenters, which includes IBM, SVC, EMC Mirrorview, Commvault, Inmage, Veeam, database clustering, log shipping and other individuals. When designing your recovery tactic, investigate numerous selections and make confident to decide on the a single that finest meets your RPO and RTO objectives. Pricing and functionality varies extensively with replication technologies, so do your homework your selections may well be far more price-helpful than you feel. Additional, by coupling the replication technologies with utilized SAN storage arrays or upgrades at a 30-70% price reduction, and you can replicate and hold far more information on disk, rather than tape.
You will no doubt encounter lots of challenges and alternatives as you make your Disaster Recovery facility, but hopefully these concepts will get you off to a very good get started.
