Never will you find a more wretched hive of scum and villainy... From: Paul Hutchings [mailto:paul.hutchi...@mira.co.uk] Sent: Wednesday, February 08, 2012 9:49 AM To: NT System Admin Issues Subject: RE: EMC limitations?
I can't think of too many sectors that seem to have such a mix of lies, damned lies, and statistics as the storage industry.

We're still going through a storage upgrade migration. The things that frustrated me the most were: - Each company uses metrics on their spec pages that most favorably portray their product. It takes time and effort to sort through the bull and get down to the facts. - It's difficult as heck (especially from EMC, not quite so much with NetApp) to get an evaluation unit so you can run your own benchmarks. - When you're running a mixed environment of Windows and UNIX, each company will tell you it will work but you'll always be surprised (especially when you can't get an evaluation unit). Incidentally, EMC lost a sale to us because they wouldn't provide an eval. -Paul From: Sean Martin [mailto:seanmarti...@gmail.com]<mailto:[mailto:seanmarti...@gmail.com]> Sent: Wednesday, February 08, 2012 12:30 AM To: NT System Admin Issues Subject: Re: EMC limitations? I certainly didn't mean to offend you nor do I blame you for being frustrated. It's just that companies aren't going to list their lack of functionality for all to see. What you're running into is not necessarily an issue, but rather a limitation. Now a good reseller would have done a better job of trying to identify your requirements and then used those to pitch a higher-end solution (if justified). I'm assuming Lyris won't allow attachments so I'm forwarding the template to those that expressed interest individually. - Sean On Tue, Feb 7, 2012 at 9:08 PM, Kurt Buff <kurt.b...@gmail.com<mailto:kurt.b...@gmail.com>> wrote: On Tue, Feb 7, 2012 at 18:10, Sean Martin <seanmarti...@gmail.com<mailto:seanmarti...@gmail.com>> wrote: > Well this is one of those scenarios where I think the customer needs > to take responsibility.

This is EMC for crying out loud - arguably the leader in the field, and it's a software issue. We're not talking about going with lesser hardware, which can steeply influence the costs. As well, I was given to understand that this is a relatively new line for them. They have the software in hand, and my 4 year old Lefthands don't have this limitation. I do place this 99% on them (split in some fashion between EMC and the reseller). I'll hand the 1% to my manager, who had used them before, doesn't like the Lefthands, and trusted the reseller rep he's worked with at his prior company. I was given no say in the matter - I suggested another LH unit. > It may be too little too late but I'd be happy to share the template we used > for our last storage purchase. That might actually be a nice thing - we might not technically outgrow the unit, as it can stack a huge number of disks, but I don't see us doing a whole lot more with it, given that limitation, and the other that raised my dander. > - Sean > > On Feb 7, 2012, at 4:29 PM, Kurt Buff > <kurt.b...@gmail.com<mailto: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<mailto:seanmarti...@gmail.com>> wrote: >>> I believe the next versions of VNX (5700, 7500, etc) support SCSI 3 >>> protocol which would not have that limitation.
