more and more customers in outsourcing business have some questions about the protection of their data. Most of the solution on the market, are dedicated for data on tape (client encryption via agent, hardware compression on tape device) but solution to encrypt online (Tier-1) data are very limited and rare.
Why Netapp doesn't provide a integrated, easy solution on their filer ?
Some people will tell use Decru ... ok but in a network storage infrascture the actual supported connection is 1GB per head, so in a virtualized envrionment or you will need a lot of head or you should go to FC. So not the best solution and also the cost is 'inaccepatble'
Also dedup is a very good feature and to a great job on virtualized environment for example with VMWARE vmdk file on datatsore (=volume on Netapp). But for some type of data, dedup doesn't offer a very good "win". Take the case of database (Oracle). You win near nothing when you try to activate dedup on volume dedicated to Oracle database. But if you could use compress to compress on block level as Oracle offers with is advance compression feature in Oracle 11g R2. You could win between 40 to 60 % of space.
Compresion on storage level shoudl also be available as dedup feature:
