    You thoughts on a SAN.

    Hi,

    We are running out of disk space seriously quickly and are looking at implementing a SAN, that should have the capability of being used as virtualisation storage in the future.

    I currently have a 5406zl core switch and was looking at implementing it in the following way.

    HP 8-port 10GBASE-T v2 zl Module (J9546A)

    will give me 8 10GBe ports.

    And a

    https://secure.dnuk.com/systems/configure/rs3000x.php

    With 4 10GBe RJ45 Ports

    Or should I really be looking at SFP+ connections between the storage and the servers.

    Comments/suggestions please.

    Personally I'd only go for a SAN from one of the more established brands just from a long-term support perspective, others may disagree

    We use NetApp.. extraordinary service from them from a support side. Not that we really ever need it.

    Won't go far wrong with any of those or the Netapp suggested below, might cost a bit more though depending on how much educational discount you can squeeze out of them

    we are looking at the EMC symmetrix vmax se, or the clariion CX4 backed up to a celerra nas box in a different area of the site. we are expecting the projects to be costly!

    although the offerings from huawei seem to be gaining rep and popularity.

    just out of interest, what solution are you using from EMC?

    Which model NetApp do you use and how much storage have you got in your array ?

    Don't forget Dot Hill they do some very competitive product and have a licencing mode more akin to Oracle storage products.

    We use Netapp here - a basic FAS-2020 (with an expansion shelf for more disks) - it's great.

    On the cheaper side of things - I hear Thecus make some perfectly serviceable SANs for smaller environments.

    I've had bad experiences with NetApp, but them, EMC and Oracle/Sun would be the bigger names.

    We have FAS 2020's and FAS 2040's here. Total storage capacity is 65 Tb all told, spread between the filers and additional shelves on some of the heads.

    Sans are a bit overkill for me in a school.

    We run 2 x normal Raid5 storage servers which run the same data (1 is just a reserve if anything goes wrong) and it works perfectly.

    We virtualize here but I really don't see the advantages of of storing the data on a SAN. Seems like its just lining up a single point of failure.

    I can understand it if I was running 100 virtual machines in a data center or something like that but we run less than 4 on each hyper-v host so local storage is fine for that.

    we went with HDS for our SAN, theyve been great and have a local presence which is handy..

    @zag, im at about 46 VMs, just now.. the SAN has 2 controllers, 2 switches, and 2x 2x10gb into the core, and each of these are spread over 2x UPS. As well as all the raid groups in the san there are also hot spares etc. I dont see where the single point of failure comes in?
