If memory really is a constraint, then one alternative to a 780 is a "750-stretch" kit from EMC. It brings your 750 up to the max 15mb of the architecture. Ours came with 2 X 4mb arrays, and the rest of the slots can be filled with 1mb/2mb arrays for the total of 15mb. The memory boards also come with a lifetime (yes, lifetime) warrenty, so this also translates into lots of service contract cash in your pocket. The modified backplane (they just add jumpers to your existing 8mb backplane) is also warrentied, as is the modified memory controller and we still have DEC service on everything else. As I understand it, DEC also has this upgrade kit, but at the time, only EMC offered it, and only EMC has a lifetime warrenty. Just one more thing to consider... (Isn't management fun...?)
