We are in the process of making a decision on [strong class="keyhilite">SAN[/strong],  evaluating EMC, IBM and HP for their storage and site to site replication. EMC we are looking at CX4, with IBM it is DS8100, HP it is EVA4400 series solution.

Software/Hardware used:
SAN

Thanks. We'll let you know when a new response is added.

From my perspective what I would be asking is.

what are you using it for?
what application profiles are you going to apply ?
I/O profiles?
how many hosts need to access the array ever?
fabric topology applied to the SAN?
what is the life span going to be?
does it need to be able to grow?
replication you say, syn or async?
distance to replicate and method to use, WDM san extension, distance, IP gateways?
what type of technology do you want, SAS, FC, SATA, SSD?
Virtualisation technologies?
Best one, budget!

downsides?

EVA4400 limited to eight shelves and 4 host ports
EMC, Storage processors are windows XP driven and require patching from new (some times)
IBM, living on past main frame success now living in past technologies

there is no one answer as it really does dfepend on what you want to use it for, they all have upsides as well.

I would love to help but need more info

I highly recommend the EMC CX4 platform. It’s a little on the expensive side, but it is a very high quality product. My second choice would then be the IBM platform.

I’ve heard good things about Compellent. We are considering them in addition to EMC for our next SAN.

If you have limited storage administration resources, the HP EVA4400 should move to the top of your list. WIth the built in virtualization capabilities, storage administrative tasks are really simplified. If you haven’t already seen it, here’s a link to paper that describes the ease of use in terms of costs savings: http://h20195.www2.hp.com/V2/GetPDF.aspx/4AA2-4661ENW.pdf.

If I’m not too late, I have a client that is needing to find a home for a brand new IBM DS8300 they took shipment of, pre-paid for 4 years of maintenance and decided they didn’t want it. IBM won’t take it back, so they’re stuck with it and are wanting to sell it crazy cheap. May be a bit larger than you require (around 115TB) but would definitely rate very high on the cost criteria.

    With respect to the members who have already answered, I think everyone's missing the bigger picture. There are some questions that need to be answered by the OP, I think: - what level of performance from the overall SAN is required? - what level of remote replication, if any, is required? - what's the allocated budget? - what's the fabric going to be: FC, iSCSI, FCoE? - who's driving the purchase, IT or finance (or other)? Anyone can pick products off a website, or listen to a vendor with a vested interest in pushing one maker's product over another (if dealing with a third-party reseller), but that doesn't necessarily make it a perfect fit. You need to be sure to pick the product that is right for your specific needs. For example, if you have a tight turnaround for replication, yes, SnapView and MirrorView on a Clariion will work, but for consistency and speed I don't think you can beat SRDF on a DMX, but that's just my opinion. Be sure to look at the situation from all angles.
