I don't want to hop more space here, but would love it if you can send me an email when you get a minute Hi Harry,

There is one potential solution. Qlogic (who I recommend for all HBA's) makes a dual homed FC HBA. http://www.qlogic.com/Products/SAN_products_fibreHBA.aspx That should allow you to dual connect your server and install another NIC board. I have used the Intel MT-1000 NIC's and they work well for me. I'm not sure how it's going to work in your particular machine, so you have to check compatibility. You can probably find a way to convert FC to Ethernet. iSCSI used to be rigged this way. I would stay away from this. Also, some new EMC SAN's have iSCSI built in. I like QLogic FC switches for small environments. They work great and are relatively inexpensive. I'm not sure what you are referring to with the Control Center. Also, make sure you buy 4GB switches and HBA's if you bought 4GB throughput on your SAN. The new EMC can connect up to 4GB if you purchased the DAE's and drives at 4GB. I noticed that RAID 6 has been added to the 3-XX series. I need to update that post. Thanks! Hi Dr.

The CX3-10C Storage-System does support RAID 6 now. BTW, maybe EMC paid attention to your call. The CX3-10C Storage-System does support RAID 6 now.

My concern was that I was in fact going to need connections from my two servers to two switches, and from there to the SPs. That's what the documentation show, but the problem is that we have two PCI-slot dual NICs in the servers and the two targets on the SPs are Fibre Channel. It seems I will need switches that accept Ethernet cabling (RJ45) from the servers and fiber optics from the SPs. The connections from the blade to the SPs are fiber optic, and Fibre Channel (copper) from the SPs to the Control Center, where you connect to the LAN with the management port. I'm new to this, and I don't even know if there is such an animal as a switch that acts as a gateway between Fibre Channel (optical) and Ethernet (RJ45). Hey, you’re fast!

I am assuming that you mean that your servers and blade will both connect to the network through a switch. The Blade will likely include some sort of (internal) switch as well. Then you will connect the blade to the storage switch using at least two connections. The two SP's will connect to the storage switch as well twice each. That means that you will have 4 connections from the SAN to the storage switch and at least two connections from the Blade and/or servers to the SAN. This means that you will have 4 paths to the SAN. Of course, all of this depends on your config and requirements. It's hard for me to determine if anything is missing with so little information, but I can give you advice for what to look for. You need networking to: Your servers Both SP's Both SAN switches You need approprate length Fiber cables. You need enough power to dual plug each SP and battery cache, switches (network and storage), servers, and blades. You need to set asside IP addresses for each SP, each switch, and probably for blade management. There's probably more, but these are some obvious ones. Let me know if you have any questions. Thanks!

I like your sense of humor. We just got an EMC system with a blade. The best I can figure by looking at it is that the NICs in my two servers are supposed to connect to an Ethernet switch, which will connect to the blade, which will connect by Fibre Channel (optical) to the Storage Processor A and B. Is it possible I am correct? I don't want something missing when the factory guy gets here. Thanks. Harry, your site looks interesting and I enjoyed reading about you. I like your sense of humor.
