Data Hoarding: How much is it really costing you?
I have closet in my house that I keep all kinds of computer gear. Most are things from some fun project that I was working or a technology that is past is prime. There is everything from Zip drives to coax termination to a Ultra-wide scsi interface for an external CDROM. Why do I keep these things in a box in a closet? Great question that usually comes up one a year from some family member that sticks there head in there looking for a toy, coat or looking to make a point.
But on more than one occasion I have had to go to the closet of ‘junk’ to get something that helped me in completing a project. A Cat5 cable for my son’s computer, an extra wireless mouse when my other one died. Yes I could go through it all and sort it out and come up with some nice labels for it all, but that takes time. It’s just easier to close the container lid and forget about it until I realize I need something and its easy enough to grab it.
Now this is not a hoarding issue like those you see on TV where people fill their house, garage, sheds and barns with all kinds of things. Those people who show up on TV have taking the ‘collecting’ business to another level and some call them ‘hoarders’. But if you watch shows like “American Pickers” on the History Chanel, you will notice that most of the ‘hoarders’ know what they have and where, a meta data knowledge of their antiques.
When you look at how businesses are storing their data today, most are looking to keep as much as possible in production. Data that is no longer serving a real purpose but storage admins are too gun shy to hit the delete button on it for fear of some VMWare admin calling up to see why their Windows NT 4 server is not responding. If you have tools that can move data around based on the age or last accessed then you have made a great leap into making savings. But these older ILM systems can not handle the growth of unstructured data of 2017.
Companies want to be able to create a container for the data and not have to worry if the data is on prem, off prem, on disk or tape. Set it and forget it is the basic rule of thumb. But this becomes difficult due to the nature of data as it has many different values depending on who you ask. A 2 year old invoice is not as valuable to someone in Engineering as it is to the AR person who is using it to base their next billing cycle.
One of the better ways to cut through the issue is to have a flexible platform that can move data from expensive flash down to tape and cloud with out changing the way people access the data. If the user can not tell the difference where his data is coming from and does not have to change the way he gets to it then why not look at putting the cold data on something low cost like tape and cloud tape.
This type of system can be accomplished but using the IBM Spectrum Scale platform. The file system has a global name space across all of the different types of media and can even use the cloud as a place to store data without changing the way the end user will access the data. The file movement is policy based and allows admins to not ask the user if the data is needed, it simply can move it to a lower cost as it gets older/colder. The best part is because of a new licensing scheme, customers only pay the TB license for data that is on disk and flash. Any data that sits on Tape does not contribute to the overall license cost.
For example: 500TB of data, 100 TBs that is less than 30 days old and 400 that will greater than 30 days. If stored on a Spectrum Scale file system, you only have to pay for the 100 TBs that is being stored on disk and not the 400 TB on tape. This greatly reduces the cost to store data as while not taking features away from our customers.
