Avamar: single node sizing

When you replace a grid with a single node, there is often concern from customers about the amount of metadata on the grid, and if a single node will have enough storage. Regardless of the size of the grid, the metadata space is limited to 3.9TB, which (depending on the amount of deduplication you're getting) amounts to somewhere in the 500-750TB of backup data range. Conveniently, an M1200 utility node has 3.9TB of useable space. So, regardless of the size of your grid, it can be replaced with a M1200 Single Node Avamar. As long as you don't store any data on the node itself. There is a procedure to lock the Avamar from receiving backup data, and it's a good idea to run the procedure as part of the migration (or new installation) of a single node Avamar.
