We are using version 3. It's deployed on-premises. We are using it as a DR as of now. We have the Isilon in our environment, so we are taking the tertiary backups to this ECS just for disaster recovery purposes. It's secondary storage.
We are increasing our usage. Our primary storage is growing, so we have to go to secondary storage to cope with the data. We refresh it almost every six months or one year at least.
Because it's secondary storage, users don't have direct access to it. Only the storage administrators have access to it for any DR or any recovery, but the primary storage itself is used by around 17,000 people. It's one of the largest Isilon clusters in the UK. It's around 106 nodes.
