Our recommendation is to use a Dell SAN, a storage solution which offers the resilience you need to ensure your data is safe and secure.
Storage Area Network (SAN)
Fast block level storage to a centralised pool of disks that can be shared from multiple servers. It offers a high level of redundancy, is flexible, highly scalable and particularly suited to virtual environments.
SANs tend to be the most expensive storage solutions to deploy, but the improvements you gain mean that you can soon get payback on your initial investment.
