Information about deduplication in Netbackup 7.1?
We are trying to sell a new backup solution for a customer, and we want to include 3 media server with deduplication, I want to know or confirm this:
- What's the maximum addressable storage which can MS deduplication is able to manage? I find is 32TB but I'm not sure is this 32TB backend disk and doesn't need to be related with the deduplication ratio? E.g. if one MS is capable to have deduplication like 10:1 then the MS can address 320TB of real data?
- How can I get an idea about the throughput, We are configuring three identical MS deduplication nodes with the following characteristics: 2 CPUS, 6-core, Intel, 3.06GHz, 96GB in RAM, 22 HD SAS 1TB and 512MB of cache (DL180G6)?
- And We want to have an idea of the deduplication block size (chunks)? What kind of deduplication strategy Symantec use? Fixed blocks, Variable blocks? is based in hash table?
- How can I have an idea about the metadata space? Is there a calculator to know that in advance?
