I have acquired a retired 7977-AC1 server from retirement at my job. The HDDs and RAM were removed. I have purchased RAM and bought (4) 4TB HDDs with the intention of turning the server into a NAS for my home. There is an 8k RAID controller and battery (which appear to be working). I have put the 4TB HDDs into the trays and installed in the server, and launched the ServerRAID Management application (CTRL+A from boot), and attempted to create an array. I am told there are no HDDs installed, yet when I goto the list disks option - they are all there, only listed at 2TB HDDs and only 1.5G/s speed. These are 6G/s NAS drives by SEAGATE.
Doing some research, it appears the 8k controller will not see drives over 2TB. So now the quandary; do I return them and get (4) 2TB HDDs, or find another controller. I would rather have these drives, and get another controller.
So my questions:
1) I have seen the ServeRAID 8s is also an option for this server - but it appears to have a 4-port cable which is looks like a SIMPLE SWAP SATA type arrangement. I would rather keep the 8 HOT SWAP bays I have. Is there another SAS/SATA ServeRAID controller which will work in this system to give me the use of these 8 bays, and see these drives?
2) Is the 1.5G/s limit at the backplane, the SAS connector of the System Board, or part of the 8k controller's limitations. Is it possible to get 3G/s or even the 6G/s capability of these HDDs and RAID 5 support?
3) I have seen mention of the ServeRAID M5015 512MB SAS/SATA 6GBPS controller in my searches for ServeRAID and 7977. Will this one work in my system? Do I need to look at replacing my backplanes? If so, with which ones?
I know what I am asking is a little weird, but this is a really nice server and seems to have lots of growth potential (like faster CPUs, etc), looking for any advice/help provided.
Much thanks in advance,
