Capacity increase for DD2200

Question

We are looking at purchasing a DD2200 with the 7 drive configuration - 7.5 TB of usable storage. This will take care of our backup needs for the foreseeable future but if we need more space, can the storage be increased by adding 5 more drives to equal the 12 drive configuration? Or does one have to buy the 12 drive configuration to start with? Thanks much, Gerry

Hi there,

Yes you can buy half then upgrade but you get less overall capacity than you would buying the full shelf as there will be two RAID groups.

I just worked out the useable capacity recently:

Half: 6.84TB

Full:15.72TB

Half to full: 12.06TB

This is using the Base 2 calculation (1024)

Hope this helps.

Ed

Hi, is it possible to reach the Full capacity with an DD2200 7Disk + 5 Disk Upgrade when I configure it first time or when it was running? Destroying the filesystem would be no problem
