Assistance with KTN-STL4 CX Series for a school

Good day to all,

I work for a school and a teacher donated two of these units:

Manufacturer: Dell EMC

P/N: KTN-STL4

15x 146GB drives

Fibre channel speed: 15K 2/4Gb

STL4 enclosure

Dims: 15"(D) x 18.525"(W) x 5.125"(H)

P/N: 100-562-126 (2)

Controller module

P/N: T58072

P/N: T57270

In our school I work with HP hardware but we welcome all donations to our school. Since our budget is low I doing some ebay research on how to make these two EMC enclosures work, so my questions are:

I see two connector per controller that looks like a CX4 connector. Are they?

Are each of those CX4 connectors 4Gbit/s each (for a total of 8Gbit per controller) or 2Gbit/s each (for a total of 4Gb per controller)?

Im planning to get a second hand 4Gbit FC switch and connect the EMC and the Servers to that switch. Instead of using fiber cables, can I use those CX4-like connectors? I will need to get the Gbics of course.

Can I get HBAs that I can use with direct attach cables?

If someone can recommend a cheap ebay fiber switch, server nics and gbics, please let me know.

My findings so far:

P/N: 100-562-126 is the link control card for DAE3P, so it should be a DAE3P disk enclosure. You can search other P/Ns by yourself on EMC PCD (Parts Compatibility Database): https://alliance.emc.com/PCDPartners/pl.asp

How many servers do you have? You don't have to buy a SAN switch if you have only one or two servers. You can connect them just like a DAS (direct-attached storage).

The part numbers of CX4 SFP should be 019-078-032 (1/2/4G) or 019-078-042 (2/4/8G). You can search their P/N directly on eBay.

BTW, only a DAE can not boot itself. You also need a CX3 or CX4 SPE (Storage Processor Enclosure).

Hi Roger, this is what it was donated to us.

http://www.dougdeals.com/p-58509-emc-ktn-stl4-4gb-fibre-channel-storage-array-san-w-15x-146gb-15k-dr...

Currently we want to connect 4 servers, potentially 6.

Thanks in advance for your help.

Ok, quite a few servers, so you still need to get a SAN switch.

So according to your knowledge, I can get those netcards and switch and calbes and I am good to go?

You also need a CX3 or CX4 SPE (Storage Processor Enclosure), with its Vault disks (the storage OS resides in the first five disks of the first DAE).

Can you show me a picture of what are you telling me? I am not familiar with EMC.

as far as pictures, this is the front of the unit.

CX3-80 and CX4-960 might be too much high-end, CX3-10 or CX4-120 should be enough for you. For the information about Vault disks and its operating system (called FLARE), you can refer to my previous posts:

Interesting, so you are saying that I have the hard disks units but i do not have the "brains" unit? and the brains unit is what you are showing me in those pictures.

Yes. you can refer to the EMC whitepaper for the details:

http://www.emc.com/collateral/hardware/white-papers/h5534-intro-clariion-cx4-series-ultraflex-tech-w...

One SPE, one DAE and on SPS (standby battery) is the minimum configuration:
