We currently have a e2700 wich is acting as our storage for backup. We received an e2600 from a sister company. Bare with me as I am not very familiar with netapp equipment. I think the e2600 has a 3612 chassis. We would like to connect the e2600 via sas to the e2700 to expand the storage. Would sas not work for this?
Quick blurb on NetApp systems; there's 3 major types of physical systems.
AFF/FAS - Runs ONTAP OS
eSeries - Runs SANtricity
Solidfire / HCI - Runs Element OS.
As far as your 2700 and 2600 they are two different generations of the eseries controllers/arrays. You can connect and e-Eeries to a FAS platform via FlexArray. But you have eseries to eseries. I don't think there is a way to turn the 2600 in to just a shelf (maybe buy ESMs)
How is your current eseries setup? DataStores to VMware? You could just run them side by side.
The e2700 is attached to vmware via ISCSI. I would be more than happy to try that. Just to give you some information, I logged into the e2600 via santricity but didnt see any iscsi settings. Now I know that there are different firmware versions for the e2700 to set it to iscsi or fiber channel. I dont know if I am missing the settings or if it is like the e2700 and I just need to get a different firmware version. Or maybe I am just crazy.
