Let me inaugurate my analysis through an anecdote.
Imagine on the supposition that you were the CTO or the source of IT infrastructure of a joint concern. There may have been instances while you would have approached the CEO or CFO with a view to budgetary allocation for purchasing data storage.
It is on the other hand natural that if you were asked near to the present utilisation of disk storage, having achieved your homework, you would have replied that your utilisation is surrounding 40-50 per cent and substantiated it by data.
Herein lays the catch. The CFO promptly tells you to try to optimise facts storage usage to around 75-80 by cent and then return for funds. You would bring forth returned thinking what you should cook or have done.
Now, let us try to analyse specious scenarios to demonstrate the basic reasons at the back low storage utilisation, and the likely means for improving the same.
Scenario 1:
You be the subject of multiple, heterogeneous storage systems (SAN/NAS) of contrary make, model and age. They achieve not talk to each other. Each united has a good amount of stranded space which cannot be made appliance of.
Solution:
Today there are tools and steps available to integrate and consolidate the SAN and NAS boxes and that time deploy virtualisation managed by a particular console. This will help you reallocate the integral available space and reclaim the cast away space for use.
Scenario 2:
You be in actual possession of a large number of servers running Windows, Solaris and contrary flavours of Unix. Each server has a bulky amount of DAS (Direct attached storage) what one. are not accessible by any other server. The disks are of opposed interfaces e.g. SCSI, SAS, SATA etc. cannot have ~ing consolidated together in one array or box.
