As tiering becomes more and more the subject of conversation, organizations are discovering that they have a lot more stale files than they thought. A good rule of thumb, if you have only one tier of storage, is that about 2/3rds of your files are stale and should be put somewhere else.

In all this talk about active files on Primary Storage and inactive files on Tier 2, rarely do I hear the follow-on discussion that I expect given the implications of what it takes to make an active file “active”. Instead, what I hear is lots of talk about taking half or more of primary storage and moving it somewhere else. And yes, this is the initial act in any tiering implementation, but it only happens once. Assuming you implement tiering correctly, you’ll never have to do this again – which also means you’ll never get this same benefit again.
The solution to weight loss isn’t exercise or eating right. Just throw out your scale and buy bigger pants.
Let me tell you a story of a ruggedly handsome technologist and friend of mine, who recently went to his doctor for a routine checkup. Now this “friend” hears the same thing from his doctor every time he visits:
As this is being written, the Industry has aligned to put all of us in the position of needing to migrate our file data from whatever system it may be on to a new platform. If your preference is EMC, then your future is ATMOS or Isilon. If you’re in the NetApp camp, then you have Clustered OnTap (8.2 Cluster Mode), e-Series or StorageGRID. Even Microsoft has come to the table with ReFS… not to mention, SWIFT, the “cloud”, etc.
Certainly a lot to think about. As you contemplate your migration, here are a few more things to consider:
One of the challenges faced by people who work over time in any particular domain (in this case our domain file data management) is recognizing the effect of steady incremental changes. These changes become like the ticking of a clock… they get filtered out of our consciousness.
Today, most organizations treat all file data as if it were equal. It is all clustered, replicated, backed-up, archived – and more… At any given point in time, the average organization has more than 12 copies of their file data. One of our customers, by virtue of their geographies and process normally has 28. (Our current record holder.)
For years we've lived with "knowledge" that NFS is faster than CIFS... While this may still be true in general, it is not true on Microsoft systems running Windows 2012 with SMB 3.0. The new SMB 3 seamless supports multiple NICs and direct-to-memory transfers making it faster than almost all other protocols. Big Data... watch out. Microsoft is coming for you!
Today, for whatever reason, everyone seems to have their head in the cloud. EMC has Atmos (and now Isilon), NetApp has StorageGrid, HP and Dell fought over 3Par, etc. What does it all mean? How is ‘cloud’ different from ‘virtual’? Should I care? Is there any value here?
Depressingly (for me, anyway),today's generation doesn't even know what floppy drives are. In another 10 years the same will be true of 'disk' drives or 'hard' drives. This year is the beginning of the end for rotating media. You can already go to Staples and, for a reasonable price, buy an 80-gig solid state drive that is 100 times faster rotating media. Once there are no more rotating drives in desktop computers, servers will follow in a couple of years. Goodbye hard drive... you've served us well.
The bad news is that for this post I have to admit to being over 40 (maybe even over 50…).
These days I’m often fascinated to see what 30-something MBAs in high tech marketing can come up with – and how much money they get to spend once they do. The latest, of course, is Cloud Computing and Cloud Storage. What is Cloud Computing? All your data and your applications are somewhere else and you connect to them over the common carrier (read: phone company) network. We did this 40 years ago. It was called mainframe computing.
