Storage
I a currently evaluating storage products from IBM (8100) and HDS (Tagma Store) and I am interested in hearing other people's experiences with either of these products. Is one better than the other? How easy are they to manage? Any information is greatly appreciated and thank you in advance. Dave

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

I have never worked with HDS but I have always had reasonable luck with IBM. Availability of RedBooks (IBM how to docs written by people actually using the products) is very valuable.

Also once you know how to work the IBM support process you can get qualified support persons working on it very shortly…

The important part for me is how quickly I can get problems resolved. Who do you want responding to you when it really hits the fan…

    Well, my viewpoint is the opposite of rkeeters. I have not worked with the IBM storage, however I have extensive experience with the HDS Storage arrays. I find HDS Storage very reliable and the support received very responsive. As with any SAN environment, the main consideration is initial planning. Ensuring your Host OS and failover software, Switches and switch firmware level, and storage code level are all qualified. That would be the same regardless if you use HDS, IBM, EMC, or any other vendor. If you are looking at the Tagmastore, then you are looking for enterprise class storage and the ability to have active/active host multipathing. Additionally, the Tagmastore USP class allows you to perform virtualization and use the Tagmastore as a front end for external storage. i.e. if you have a netapp and you want to attach it to the tagmastore to utilize the throughput and multi-port config/etc. I could give you technical details but then I'd start sounding like a salesman. In my opinion as someone whos worked with SANs for years, the most important consideration is your support model. The storage and all the bells and whistels the sales folks will mention is great and all, but when it breaks (which they all will) or you need a code upgrade, or the ability to troubleshoot why your host os lost connectivity to storage or you cannot see luns, or you have a fabric down, then your support with your HW vendor is critical. I find that HDS support tends to be willing to help me get out of a jam even if the problem is not related to HDS storage. Anyway, I could ramble, so post back if you have any more questions or would like to know something specific. :wq!ben

    One more thing. Be sure to figure out what you have in your DC first and use a CMDB like Azazia or Onaro or something similar.. Determining host-to-switch-to-storage mappings and keeping a running inventory of what you intend to connect to your storage will save you HOURS.. and HOURS and HOURS (Getting the point yet) of troubleshooting. You need to know as much detail as possible so when you bring in your storage you can besure it is all qualified. SANS are like symphanies. If everyone plays nice things will sing. If they don't.. Well, I'm sure you've heard a violin squeek before. :wq!ben
