Storage Tiering- What is it and what does it give me?

What is it?

Since there are many disk drives types, it is very important to optimize use of different drive types to achieve best price/performance ratio for your storage. Storage Tiering allows usage of different type of drives for different applications.

Common disk drives used in storage subsystems such as Stonefly’s IP Storage products are: SATA HDD, SAS HDD, and SSD. SATA and SAS HDDs are both mechanical disk drives with spinning platters. SSD stands for Solid State Drive and is made from non-volatile flash memory. HDDs come in different rotation speeds ranging from 5400 RPM (Rotation Per Minute) up to 15000 RPM.

 

In storage Tiering, the most reliable high- performance equipment is used to support the most critical data. Whereas, the most cost-effective resources to support older, less critical information

 

All three drive types are available with:

–      3 or 6Giga-Bit-Per-Second per port

–      Single port which is commonly called SATA interface, or SAS interface which is commonly called SAS interface.

All three drive types come in different capacities of up to 3Tera-Bytes, and these capacities keep increasing each year.

 

This many variations in drive type, capacity, interface, and speed results in large differences in price for each drive.

 

Storage companies offer wide variety of drive types to accommodate needs of different customers with different applications. Storage Tiering allows customer to have multiple drive types in their storage units, and gives them the ability to allocate certain type drives to certain applications depending on what that application needs.

What does it give me?

Answer is simple: Freedom to choose drive types depending on application, and overall reduction in data storage costs.
