It's good stuff but they don't have a certification/training program for it. As such I would suggest you check out SNIA's SCSP program. They have identified a great set of resources (books) that cover all the key areas of knowledge required: http://www.snia.org/education/storage_networking_primer/

I did read the SANS & NAS book and I only recommend it as a general introduction to SANs. The book is very thin and half of the book is spent discussing backup methods and technologies. Preston, the author, is a backup guru so that shouldn't be surprising. I haven't read the dummies book, even though it got excellent reviews on Amazon. I really considered it, but the copyright date was 2003. RFC 3720 wasn't published until April 2004, so I didn't expect the dummies book to have much - if any - iSCSI information. The SANS & NAS book has only a paragraph or so on iSCSI, despite it's claims of being 'updated'. The EMC SAN my company just purchased is primarily iSCSI, so my book and training choices focused more on iSCSI. I have a few SAN books in my library, but the one I actually read while studying for my EMC certification was Storage Networking Fundamentals from Cisco Press. It was an excellent vendor-neutral overview of Storage Area Networking technologies. I read it while going through the EMC e-learning courses for the Storage Technology Foundations exam and I felt the Cisco book nicely complemented the EMC courses. So far, I have only skimmed the Storage Networking Protocol Fundamentals book from Cisco Press. I have only read about half of the iSCSI: the Universal Storage Connection, and it appears to be out of print now. Although it was published in 2002, the author sat on the IETF commitee that drafted the iSCSI standard so it is still useful as an iSCSI overview. I also have a copy of Designing Storage Area Networks by Tom Clark who has written several well-reviewed SAN books. I plan to use all of these as references while I pursue the EMC Proven Specialist : Storage Area Networks certification. As for the EMC Proven Associate certification and the Storage Technology Foundations exam, you can find my review of the exam here:http://www.techexams.net/forums/viewtopic.php?t=32420 My primary complaint about the exam is that the applicable training is only available from EMC and is expensive. My company purchased training credits with our new arrays and I applied those to EMC e-learning courses, otherwise I wouldn't have been able to achieve this certification on my own. In addition to the SNIA certification, Hitachi also offers a certification - the Hitachi Data Systems Certified Professional. Those of you selling or supporting Sun and HP rebranded Hitachi arrays might want to consider this one as well.

If you're looking to further your career, you sorta need to get vendor certs like Brocade, EMC, Cisco, NetApp, etc. That's the dilemma I'm in. I want to get into storage, but the company I work for won't get into robust storage solutions. Due to my VMware and large scale Exchange experience, storage is a very logical path of career growth for me, but it's hard for me to get into it.

Unfortunately, most of their clients are either small orgs who end up with simple storage solutions like HP MSA's or DataCore's SANMelody, or they're so large, they have their own storage team, and we just do our piece of it. I have been pushing them to get into storage, specifically NetApp because it rocks for VMware.

I have been pushing them to get into storage, specifically NetApp because it rocks for VMware. I have a friend who does storage, and while SNIA is well respected, he said vendor specific certs of the large players like EMC, NetApp, Brocade, etc. are what get you paid. Salary reviews of certs reinforce this, as Brocade certs command some of the top salaries on average of any certs you can get even outside storage.
HeroPsycho wrote: And NFS that NetApp offers over MSA's for VMware kicks serious butt, tool. Once you're scaling to 100 VM's or more per ESX server, NFS blows the barn doors off iSCSI.
HeroPsycho wrote: iSCSI and FC have a single disk queue, where as NFS doesn't, and handles the locking better. I wouldn't purchase separate storage for VMware without good reason either. The issue we're running into though is the companies we're doing VMware for don't usually have a storage solution, so they need that, too. Typically speaking, the consulting company that can bring the storage solution to the table is the one that wins the VMware work. If it's an org of any size, we basically get blown out of the water because a competitor comes in with NetApp against our puny MSA. No contest, we get destroyed. And remember, with NetApp, you don't have to pick NFS over RDM. You can do both with the NetApp (separate LUN's of course).
