Well this is one of those scenarios where I think the customer needs to take responsibility. A good practice to get into is the creation of technical requirement matrices and business requirement matrices. It helps you put on paper what capabilities you need in a solution and gives the vendor a uniform method of informing you of the strengths and weaknesses of their platform. We typically tier our requirements into 3 categories that allows us to weigh the importance of features. For example, a tier 1 requirement might be that the solution support fiber channel or iscsi where a tier 2 or 3 requirement might be support for sub-lun tiering or a 64bit OS to leverage larger cache.
It may be too little too late but I'd be happy to share the template we used for our last storage purchase. - Sean On Feb 7, 2012, at 4:29 PM, Kurt Buff <kurt.b...@gmail.com> wrote: > If true, it would have been nice of them to disclose that before > purchase, methinks... > > Kurt > > On Tue, Feb 7, 2012 at 17:04, Sean Martin <seanmarti...@gmail.com> wrote: >> I believe the next versions of VNX (5700, 7500, etc) support SCSI 3 >> protocol which would not have that limitation.
