DD2500 upgrade options
Hi, I'm pushing Veeam backups to our DD2500 via DD Boost. But its filling up over 90% already, using 28TB out of 31TB. It already has an expansion shelf full of 2TB drives.
What are my options for expansion? It looks like you can't add another shelf to it, yet the spec sheet says it can go up to 133TB. Do I have to replace the disks with 3TB drives or can I add on another shelf?
Please advise my options.

Hi,
DD2500 has either 7x or 12x 3TB disks internal to the controller - referred as 21Tb or 36Tb (raw).
Depending on whether it was sold as 12 disks or upgraded, you get useable; ~11Tb (7 disks), 21Tb (7+5 disks) or ~25.9Tb (sold as 12 disks). Figures are approximate.
You can add up to 135Tb of external storage shelves on top of the above in the controller.
That is made of a max shelf count of 3, and so 3x 45Tb shelves (3Tb disks).
You will get around 32.7Tb per (45Tb) shelf useable.
Hope that helps. Jonathan

DD2500 can support expansion disk shelves. I believe you have one card/port and can expand to 4 ES30 (normally you would need redundant connections, but according to https://support.emc.com/docu58943_Data_Domain_ES30_Expansion_Shelf_Hardware_Guide.pdf?language=en_US&language=en_US DD2500 is exception. You can visit https://store.emc.com/us/Product-Family/DATA-DOMAIN-PRODUCTS/Data-Domain-DD2500/p/DDM-DataDomain-DD2500 and select chat option - they can check what you have and tell you exactly how much you can upgrade.
