Problem with SANsymphony is...
I looked at this product and it seemed to tick all the boxes. I wanted a SAN solution where you could quickly and easily add an extra TB or so using inexpensive disks as storage needs increased.
Using Tier 3 storage for large multimedia files and having a quick HA backup or even adding a plug in external drive for a quick fix solution.
So I got a quote will all the prices and then asked about what happens when you want to add more storage. Suddenly the SANsymphony software (which runs on Windows 2008 which you had to licence, and all your own hardware) requires a licence to use that extra TB on each server (both of the mirrored nodes).
Therefore to use the £100 1TB drives that you buy you have to go cap-in-hand to the board for almost £1000 to licence it. Seems excessive for the market it is aimed at and really spoilt the flexibility of the product.
