We are using Dell R730XD's with 2 x Internal SAS in Raid 1 for OS. 24
x 400GB SSD.
PERC H730P Mini is being used with non-RAID passthrough for the SSD's.
CPU and RAM specs aren't really needed to be known as you can do
whatever you want, however I would recommend minimum of 2 x quad's and
at least 48GB of RAM.
NICS are 4 x 10G (2 x 10 bonded for cluster, 2 x bonded for public).
Naturally, you have the 4 x 1G on-board too.
Performance is very good for us.
Quite the same here too, with a mix of R730xd for capacity tier (Pure
mechanical 8 Gb drives) and 2xR630 for SSD tier.
1 problem to be aware of :
-> We have "write intensive" Dell-branded SanDisk OEM (LT0400MO), and
there is a problem with stock firmware : When used with H730P in raid0
mode, it works like a charm. When put in HBA mode, as soon as you start
to write data, you have almost immediately SCSI write errors with the
disk marked faulty, an then it's a brick :/ . Firmware D413 fixed the
problem ("faulty" disks were changed)
So before doing extensive tests, if drives are of this model, make sure
you have latest firmware :)
Cheers,
Yann
