Analysis of comments: HSM Rising big Data fueled?

HSM is the hierarchical Storage management abbreviation, meaning "tiered http://www.aliyun.com/zixun/aggregation/14290.html" > Storage Management. Refers to the process of automatically migrating data between storage devices. Tiered storage management can be stored at a lower cost, delivering cost-effective storage services. But reduced access performance.

There were even vendors who said that tiered storage management was dead. The reason is that HSM lowers overall storage performance, and today's mechanical hard drives and hard disk densities can solve all of today's storage problems.

However, in recent years, with the advent of the big data age, more data needs to be stored, and countless EB data storage costs let us begin to notice the high cost of storage equipment. So does HSM usher in a comeback?

I think the answer is yes, the reason is simple, in the future, we need to find more information value, data is not value, only useful information to produce value, which gives HSM new opportunities.

Just as long ago, DNA between chromosomes was called junk DNA, but now it is known to be a completely false description, and it has a very large relationship with disease and DNA replication. Similarly our data is like this thing, although there are many, but there will be different user needs.

The data must be preserved for the descendants, because we do not know which day the data can become the value of information, whether this data is the traces of earthquakes, oil, DNA, climate and so on data, we need to be well preserved.

Today, HSM is the way to isolate raw information, to maximize the cost of our data storage, and we need to familiarize ourselves with HSM functionality for a long time because he may be a long-term technology that needs our attention.
