Connect FX2 with DELL EqualLogic PS4210
We are interested to aquire a FX2 with two FC630 at the moment with future possibility to add additional 2 nodes.
We want to connect FX2 with EquaLogic PS4210. At the moment we will have only one chassis of FX2 and I want to know if I can connect directly the storage to I/O Aggregators.
Looking forward for your reply.
Kind regards,
Kushtrim

I have a FX2 with 2 FC630 and a FD332 in front of me. It was planed as phys. servers but we decide to place a vsphere esxi on and run single VM on each. We have a larger 10Gb EQL/CMPL in the background.
The 2 IOMs (8 internal and 4 external Ports each) are independent and offer some options. The IOMs running FTOS9 but they "feel" a little bit different compared to our s4810.
- The IOMs have not an (option) to connect them internaly
- Port9 (the first external) can be used to stack them. If you connect a single PS4210 you have 2 Ports left. It the stack acts as normal the share a single IP and if you upgrade FW both switches may reboot on the same time. But iam not sure about that and you have the ckeck this out befor using the stack option.
- VLTI can be used. Normaly 2 cables are needed together with a 3rd one for the Heartbeat. With that youre unrring out of ports. Also if only one cable and another one for Heartbeat is used.
So..... check out the stacking option and when more LAN ports are needed but a dual port 10G PCIe card for each FC630.
We create a LAG (2 Ports) from each IOM to our pair of s4810 which used VLT.
Hint(s):
- There is a HTTP WebGUI running on port 8010 called Blade IO Manager on each IOM
- We use the nPAR feature of the Broadcom/Qlogic NICs of the FC630. So our ESXi see 8 NICs in total for "better" configration options.

Note: If you connect a EQL to a switch fabric the ISL bandwidth between those switches needs to be around 75% bandwidth of all EQL ports. This means you need something with 15Gbit/s but with only one stacking cable you only get 10Gbit/s.
With just a single PS4210 i would ignore this best practice.

Ok, over the weekend we play around with the IOM and its Port 9 which is used for VLT and unlike normal Force10 switches you can use only one cable without the use of a extra Heartbeat.
All over all iam not sure if its a good idea to directly connect a IP based storage to the 2 IOMs and a extra TOR switch sounds the better solution.
