Adding a Dell MD3200 to a MD1200 to allow clustering?

Hello Everyone,

I found out last week that my Dell MD1200 DAS does not support clustering for virtual environments. While searching for other solutions, I found out that the MD3200 does support it and also that you can connect 3200's to 1200's. My question is, if I add a 3200 to the top of my 1200, will this now make the 1200 cluster-able due to the fact that the 3200 is in the mix?

Thanks for any help, Dell hasn't been ANY help.

Hi

we use couple of MD3200i as iSCSI cluster for hyper V hosts.
also MD3000 DAS for same
but never tried linking together,
I believe connecting MD1200 with MD3200 (is it iSCSI or DAS) should just provide you extra capacity for MD3200 and still let you use all functions of MD3200 as normal.

PV MD1x00 series is designed as extension module for MD3x00 series. So, yes, if you have MD3200i you can extend it with the MD1200 and use both units in a cluster.

However, if you planning for an expansion I would recommend looking at EqualLogic. EL uses much more advanced technology making the addition of a new unit a piece of cake. They can be stacked up to 16 units into a single array.

 Unfortunately, mixing MD and EL is not supported.

We recently acquired a PS4100XV to replace our MD3000i.

It'll certainly work as an extra disk enclosure on the MD3200 as already mentioned but that may be only far as hardware is concerned; I don't think Dell support data migration by moving the enclosure from a DAS environment to a SAN one. Nothing hard about adding enclosures to a MD3200 and they're certainly a lot cheaper than EqualLogic.

What host connect protocol do you want with the MD3200? You have the choice of iSCSI, fibre channel or SAS although SAS is generally limited to four HA hosts due to lack of switches for SAN fabric expansion.
