We have an HP XP12000 SAN with 450 Tb of data, with multiple types of RAID config. We want to reduce the size of the SAN, which we see as happening in two ways: a. Reduce RAID 5 to a lower but still resilient level and b. Trawl through the data remove duplicates etc. Two questions - a. What is an optimal resilience level? and b. What tools (SW etc) are available to manage and control data? FYI - we use SAP R/3 and BW with CRM coming soon. We also have an very active web site.

Depends on your business requirements. RAID 1/0 may be perfect for some, RAID 5 or RAID 6 for others.

>b. What tools (SW etc) are available to manage and control data?
Double Killer is a nifty piece of software that will find duplicate files: http://www.bigbangenterprises.de/en/doublekiller/

But it sounds like Data De-duplication might be what you're after, given that you've got a mix of structured and unstructured data. StorNext from Quantum (http://www.quantum.com/Products/Software/StorNext/Index.aspx) might be just the ticket. It handles HSM tasks as well as de-duplication.

Alternatively, you could wait until HP releases de-dupe for the XP series of arrays.
