back to article Loved-up shared storage silos in SHOCK SPLIT!

A previously uniform shared storage architecture is splintering apart as server virtualisation, dedupe, flash and the cloud shatter the old order – giving us five steps to heaven, or hell, depending on your viewpoint. The old shared storage order was a bunch of servers linked across a network to a storage area network (SAN) or …

    Exactly where we have ended up..

    This reflects our experience and is exactly where we have arrived. Our stack looks like this

    ESXi Hosts

    Hybrid iSCSI SAN

    Disk to Disk Backup with Deduplication

    Disk to Cloud Backup for archiving (Documents, call recordings etc to Glacier)

    Disk to Tape Backup for DR (Virtual Machine images etc)

    Coming up with a strategy for Cloud Backup was quite difficult for us, in the end we decided it only had 1 benefit which is long term storage of cold data at a reasonable price. Cost wise, we have been very pleasantly surprised, we uploaded about 3TB of data (consisting of around 700k files) and the total for the month was about £20.. I would never use this for DR purposes, as we calculated this would cost a small fortune to recovery a large volume of data in a short period.

    "Suppliers like Nasuni say the cloud can be used for primary storage with local caching appliances."

    Maybe for the "junk" fileshares where all the crap accumulates - but unless they have a 100% uptime grantee and compensation scheme to cover company costs and lost revenue, forget it!
