As in my first blog 'Thin Provisioning - How Symantec Can Help' we recognise the "data explosion" as fact rather
than fable and as before is set to continue for the foreseeable future.  Projected growth rates are inexact
however all are in agreement that data creation and retention is on the rise, placing further demand on an
already stretched IT storage team.

Again most customers I speak with are investigating some form of data/storage optimization. 
Often the largest spend of the IT budget is storage, and of course CSO’s and CTO being tasked with reducing this.
Solutions available vary from something as simple as  migrating data from tier 1 storage to adopting newer
technologies such as, SSD’s, Thin Provisioning, along with known technologies such as  compression, dedupe,
the list goes on….

Today’s blog will be targeting space utilization and more specifically Compression, as stated the nirvana for
most organizations is to get the best utilization from their storage at the best price point.
So what Symantec S/W are we talking about? - again, Storage Foundation.
Let’s focus on compression and how this can offer space savings.

What is compression ?
Simply put, compression is about reducing the file size of one or more files/directories.

Why compress ?
Analysts predict that 60% of storage after creation is never accessed again, clearly it makes sense to target
this data for compression.
 
What data is a target for compression ?
Typically we want to compress data, when after creation it is not read or written to frequently, e.g. :
Unstructured data, Archive Logs that grow to a limit and then stay unchanged – i.e.
Oracle archive Logs
Engineering data that are versioned and stored for long periods.

What value does Symantec's Storage Foundation compression bring ?
Users can report on the amount of storage saved by compression.
Flexible compression algorithms, to a allow for different levels of compression in accordance with specific
access requirements.
Finally reads of the compressed data do not require uncompressing, the target data can be read in memory.

Symantec’s values are that there is that we have no H/W agenda and we realise no benefit from selling more tin,
we genuinely want customers to achieve space saving benefits.
 
Simply is it worth having a further look at what Symantec has to offer ? If you want to use your storage more
effectively and get the full benefits from adopting compression, Of course, the answer is Yes !
