Solved: FAS2240 or FAS3210? - Page 4

Hello everybody, i'm new in the community and in January 2012 i need to change my old EMC clarrion with a brand new Netapp.My enviroment is 3 hosts with Vmware.

I ask to my dealer and i've received 2 configurations, one with the new 2240 with 28 disks 2,5" 10krpm, 4FC port and another with 3210 and 28 disks 3,5" 15krpm and 4FC port, the price

is 4.000€ in favour of 2240, but isn't a problem.

My dealer told me that the 3210 is old than 2240, but is an high level SAN than a 2240, but i've several doubt, because i've read the new 2240 have a new processors, is a 8gbs FC vs 4gbs in 3210, also the cache is bigger in 2240. Only disks seems to be better in 3210 ( 15k rpm) than 2240 (10k rpm).

In the papaer seems to be better the 2240 than 3210, but is it true?

Thanks in advance

Don't be alarmed by 10k SAS disks. They offer about 15-20% less iops per drive compares to their 3.5" 15k SAS counterparts.

In most VMware environments this isn't an issue, but YMMV.

It is also good to note that the 2240 can hold 24 disks internally (not 28).

SAS Expansion shelfs can also hold 24 disks (DS4243 (SAS/SATA/SSD) or DS2246 (only 10k RPM SAS).

If your dealer really quoted you 28 disks, then perhaps they offered an empty 2240 with 2 DS14Mk4 FC shelfs (they hold 14 disks each) ?

On a 2240 I would never use FC shelves, because then you need the FC mezzazine for shelf connectivity.

Go with SAS shelves ! Also on the 3210.

Regarding networking: dual 10Gbit in a 2240 controller is nice. But you'd need two 10Gbit switches, and two 10Gbit nics per server.
