All flash arrays are flooding the market like never before and companies looking to upgrade their storage environment are showing more interest in having these solutions in their data center premises. But when it comes to cost, it’s not that easy to impress the decision makers and this is where a hybrid appliance which has flash and disk populated in the chassis shows its significance.
A hybrid appliance has SSD to address performance issues and disk drives to address capacity issues. A storage controller smartly managed by software helps in channelizing the data to the appropriate media as per requirement.
In order to understand the process more deeply, first let us look at the basic taxonomy of storage tiering from primary to cold.
Primary data- This type of data is the data which is being accessed on a frequent note. So, placing this data on a flash drive, helps meet performance issues seen in environments like financial transactions.
Warm data- Warm data is the data which is not being accessed on a frequent note, but needs to be available for business objectives. This data when placed on SAS hard disks will be accessible on demand.
Cold data- The data which is not being accessed on a frequent note and is more of archival purpose is called as cold data. Though, the data is used for archival purposes, it has to be within the vicinity of the storage controller. So, placing this data on SATA discs makes complete sense.
Now to know on how tiered storage helps in saving costs and have high level accessibility, follow the article further.
Now, imagine, if you are going for an All-flash array. Agree that these arrays are apt for those environments where performance of data storage can make or break a business. But if someone is looking for storage that economically works out for their business on capacity and performance scale, then All-Flash may not be the right solution for their environment. And this is where a Hybrid storage solution which has flash and disk in it will be the right choice.
Furthermore, enterprise data storage solutions are nowadays including tiered storage as a default feature and that’s due to the fact that it helps in saving costs and solves accessibility crisis.
StoneFly,Inc. offers IP SAN, NAS and Hyper Converged storage solutions which are induced with tiered storage potential. StoneFly’s patented StoneFusion operating system smartly manages data flow between SSD, SAS and SATA hard drives. The frequently accessed data is moved onto SSD in an automated way and the warm data is channelized onto a SAS drive. Cold data is moved onto the low cost SATA hard drives.
Thus, with this arrangement performance & capacity issues will be solved by flash and disk and the solution will be available within the budget–atleast not as high as a flash array.
