I need some suggestion on best way to configure this old filer for performance.
It has one DS14 shelf of 36 GB drive, 1 DS14 of 18 GB drive, 1 FC9 with 9 GB zoned checksum, 1 FC9 with 18 GB zoned checksum and 1 FC9 with 36 GB zoned checksum disks. I'm using the 9 GB FC9 drives as root volume since these drives' performance seems to be really slow. This should not have negative performance impact, right?
I currently have 12 of the 36 GB drives in the DS14 configuired as 1 volume and the rest configured as another volume. I'm leaving 2 of each disk type as spare just in case due to the age of the drives. Now the users are telling me that the performance is really slow. They say that the performance is only a quarter (25%) of a volume with 14 DS14 72 GB drives on our other FAS940. I thought the 840 is about 60% of a 940? Does this look like some kind of configuration issue or is this about what it's supposed to do? Would I get better performance by combining all the drives into 1 volume? I've never dealt with zone checksum drives. How much performance do I lose?

Our parent company has a old netapp (F840) that they are lending to us for a 2-month critical project.
Unfortunately the machine is out of maintenance. It has old X219F, X221D, X225B, X233A and X234B drives. I saw on NOW that these are all pretty much EOA drives. X219F is even End of Hardware Support. Does that mean basically you can't get them from NetApp at all?
For the other drives, we are checking to see if we can get support for them. Although for 2 month, maybe we are better off just purchasing them from support? Is that something that we can readily do? What kind of turn-around can we expect? Anyone else been through this before?
