LinkedIn groups (well some of them) are buzzing with the posts that All Flash arrays will take hold of the entire data storage industry in next few years- making HDD and Tape solution providers almost extinct in coming days.
But is this really possible in reality? Let’s do some basic analysis on this and find out for ourselves.
In an enterprise data center, different applications have different storage requirements mostly influenced by IOPS. The apps includes, mail server and mail storage, OLTP, Databases, scientific or engineering, customer support, video creation and distribution, archiving and backups. The Input and Output access of these apps differs at many stages which also influences storage requirements.
This is where the need for multiple storage media in the storage architecture is needed to meet price and performance ratio on a perfect note. Having flash and HDD on-board leads to a hybrid storage that balances the cost vs capacity factor on a perfect note.
A hybrid storage solution has both solid state and rotational storage working in the background. In this scenario, the solid state storage is often used as a mega cache which provides accelerated IOPS from and to the array. Hard drives offer the capacity requirements to enterprise applications.
Coming to all-flash systems, it is a simple array which doesn’t contain rotational storage and is populated with SSDs. All data is stored on these expensive drives which forsake capacity for massive performance. Businesses which need IOPS, such as those in financial sector, will love to have such arrays in their data center. Data reduction technologies such as compression and deduplication can help companies combat with space issues.
However, they are two challenges which are hindering the deployment of All flash arrays in enterprise sector. The foremost is that most CIOs simply do not need the levels of performance offered by all-flash arrays. They need affordable storage in most cases and need a bit of due performance for some of their applications. While, all flash supports the performance need, it still remains much more expensive than HDDs, even when data reduction is taken into consideration.
So, what most CIOs feel is to have a solution which combines the best of what both the SSDs and HDD worlds have to offer and create an array that leverages the benefits of solid state storage for performance while continuing to be able to rely on the massive capacity benefits inherent in HDD based solutions.
This is where hybrid storage arrays prove their prominence as they offer best of the two worlds at a fraction of cost.
