I've gotten a few conflicting aswers about this. We're working on an upgrade of the storage, but not the servers, and the servers are only able to run at 1Gb. We're wanting to install FAS2552. The servers are IBM BladeCenter S-series. I know the UTA2 is only 10Gb, so would I be able to attach the servers using the 1Gb Ethernet? They seem to be listed on HWU as available, but have heard from our sales rep that they can't be used for data. Any info is appreciated.
If you feel you're not receiving the correct information from the Sales rep. ask to speak with a technical sales engineer. All sales reps. have dedicated sales engineers to answer the correct technical information.
Each controller on the 2552 has 2x 1GbE copper RJ-45 ports that absolutely can be used for data. It is a great system for exacrtly this reason. Customers can start with 1GbE and can upgrade to 10GbE when thier infrastructure moves to 10GbE.
Your sales rep may be referring to the "Wrench Port" which is a dedicated management port that is not to be used for data. There is also another 1GbE copper port use for the ACP (alternate control path to the disk shelves and again is not to be used for data.
Orange/Green = UTA2
Black = e0M/SP for Dedicated Management (Wrench Port)
If we have 10GbE ports on 2552, can they autoconfigure to 1GbE if we need more then 2x1GbE iSCSI ports per controller? I need system which has 2 x Fc per controller nad 4 x 1GbE iSCSI (old 2240 config) and i total per system 4 x fc and 8 x 1GbE iSCSI? Is this possible with 2552?
