Test Your Storage Optimization IQ

Here’s a quick quiz to see how smart you are about primary storage optimization:

1. True or false: the only type of deduplication on the market today is block level deduplication–the type that looks at the zeros and ones on disk, and removes the duplicates.

2. Content aware deduplication is:

a) More effective than other types of optimization for primary storage;

b) The best approach to optimizing online files, such as photos, PDFs, and other already compressed files because it extracts them and reads them in their non-compressed format before optimizing them;

c) Only available from Ocarina Networks;

d) All of the above.

3. True or false: dedupe gets 20:1 data reduction results the first time it passes through your data.

4. With online data sets, block level dedupe and content aware dedupe get:

a) About the same results;

b) Different results–block level is better;

c) Radically different results–Ocarina’s content aware deduplication solution gets 5x or better results than block level dedupe.

Answers:

1. FALSE. There’s a new type of dedupe on the storage scene–content aware dedupe. This works in part by analyzing the ones and zeros in files that have been extracted out of their compressed format–a far more effective approach for the types of files that are driving storage growth, such as images, PDFs, and Windows files.

2. d-all of the above.

3. FALSE: Block level dedupe gets its results because of the repetitive nature of backups – daily backups create dupes, dedupe takes them back out. For online data sets, you won’t get those results, because it’s not a repetitive data set.  You need a different approach that can find the dedupe and compression opportunities in a single online set of files.

4. c–see the chart below for a comparison of results.

Storage Optimization – The Trend Picks Up

Several news articles in the past week are responding to reports about the continued skyrocketing growth of unstructured data, and the technologies that are coming up to meet this new set of demands under today’s economic circumstances. 
Here are a few of the articles that jumped out at us:
Processor
NetworkWorld
InternetNews
As we’ve often mentioned, a combination of solutions is called for when it comes to capacity optimization, one of which is content aware compression, such as that offered by my company Ocarina Networks. Given the state of the economy and everyone’s focus on cost savings, we have no doubt that this trend will pick up in 2009 –dealing with the costs of growing data by having it take 90% less space to actually store is a win-win all around.

What’s Hot in Storage — Spending Less

Byte & Switch has once again released its “Top 10 Storage Startups to Watch” for 2008, and it’s definitely worth a read. My company Ocarina Networks was on that same list last year, and so I can say with confidence that they got it right at least once before. 

As reflected in this year’s list, data reduction technologies continue to be hot. Makes sense in a down economy that anything that increases capacity will continue to get budget dollars. As we’re finding, dollars for stuff like Ocarina is already there in every data center’s budget – it’s just listed as disk expense. We’re not only ahead of our revenue goals for our storage optimization product launched in April, but we’re having to triple the size of our sales force to keep up with demand. 

If you have planned to buy 100 TB of disk, and can spend half as much for an optimization solution that shrinks your files that means you don’t have to buy any disk at all. A win all the way around. While Ocarina started out with wins in large web sites – where the fastest year-to-year storage growth is taking place – we’re now seeing installs in life sciences, energy, movie studios, and finance.  

The chief takeaway from what I’ve seen: some nice-to-have new technologies may be facing a tough summer with an economic downturn, but data reduction scores high on both saving money and green IT, and is likely to stay strong, or maybe even move up in priority, during a down cycle in storage spending.
