Clariion CX3-20, SAN switch connectivity and Hyper-V clustering
Hello, i need help with or if anyone can point me in the right direction. I have a project in which we purchase another SAN swtich (Brocade 5000, 32-4gb ports fully activated), 2 Dell Poweredge R710 and 2 fully populated DAE with 15x1TB 7.2k SATAII in each enclosure. All this will be for a virtualization project. My current setup with our CX3-20 is as follows:
- Fibre ports connected in the back of the unit: SPA=0 & SPB=1 connected to one of the Qlogic5200 SANbox (there is still SPA=1/SPB=0 that are not connected)
- 2 Qlogic 5200 SANbox switches which is where all my servers, backup units and our EMC SPA/SPB are connected.
* What i like to know is:
- With our Brocade 5000 switch in place, can we connect the fibre ports that aren't connected (SPA=1 / SPB=0) to the switch, connect my servers and zone them up.
- Is there any particular way i have to configure the storage? The 2 DAE with 15x1TB 7.2k SATAII drives will be combine together and allocated to be shared under our failover clustering of the 2 Dell Poweredge servers running as Hyper-V hosts. As far as the additional unconnected fibre ports..can those be connected at the same time to the Brocade switch while the other 2 are connected to the Qlogic?
I know it may sound like a lot to ask for, but any help is appreciated.

you can connect SP ports to any switch fabric you like, as long as each fabric has SPA and SPB ports. SATA drives for virtualization projects ..hmm, don't expect a lot of i/o out of those.

Thanks for the fast response dynamox. Reason for going with 1TB 7.2k SATAII drives simply management wanted to do it cost effective. The price of the 15k were a lot higher, so we were working within a strict budget and try to stretch it as much as possible. So in regards to connecting the additional fibre ports to the Brocade fabric.. you don't see any connectivity problems with our current Qlogic 5200 connections and are the additional fibre ports for full redundancy? We will be live migrating 26 current VMs and a possible 28 Physicals. Do you know of any manuals that explain how to prepare the LUNs for virtual storage? Thanks again.

let me make sure i understand what you are trying to do. You have an existing SAN that consists of two fabrics, one Qlogic 5200 for fabric A and another Qlogic 5200 for fabric B. You have x number of ports on CX3 connected to these two fabrics as well as some servers. So now you have two new Brocade switches, you will connect the remaining CX3 ports to each Brocade switch as well as the new servers. Did i get that right ?
A couple of questions:
1) how many CX3 ports currently connected to Qlogic
2) how many HBAs on the new servers ?
3) current version of Hyper-V

For question 2, you can refer to Microsoft's official guide: Optimizing Performance on Hyper-V
