Think of a Storage Controller as an embedded processor chip that can do a wide variety of functions. It is a separate “space” that controls the volume exchange, provides an interface for SSDs, HDDs and other external mediums, and pre-caches active information for better flow of data.

All storage controllers have an input and output path for communicating between the storage network and the Direct Attached Storage (DAS). Input

A processor is present that handles the I/O functionality, managing the Redundant Array of Inexpensive Disks (RAID) and the volume being sent through the controller.

It also performs the complex tasks of cloning, taking snapshots, de-duplication and thin provisioning for efficient and loss-safe data access throughout the data center lifecycle.

Storage Controllers are the main facilitators when it comes to data center performance. In short, it can be said that the overall data flow is dependent on a storage controller’s performance.
These factors effect the performance of storage controllers.- Speed:- Data Bus Capacity:- Thin Provisioning & Snapshots:- Automated Tiering:

SPEED• The top-most priority should be a high-
speed storage infrastructure to process & perform data colocation.
• The controller needs to efficiently communicate with the attached disk drives for flawless data transfer.
• The drives need to be in unison with each other for better performance.

DATA BUSPreviously, SSDs used to surpass the speed of
storage controllers therefore, they had to be scaled down.Now storage controllers are available with more capacity (up to 12Gbps).

THIN PROVISIONING & SNAPSHOTS
Thin provisioning, cloning and system snapshots every second can clog the storage space. The storage controllers pre-allocate space in the storage devices for this purpose, but if more data needs to be stored, the pre-allocated space has to let go of the system image, thus slowing performance.

AUTOMATEDTIERINGAutomated Tiering is a method by which seldom-used information is kept in slow speed drives, such as the hard drives. The controllers have to analyze access patterns and statistics of various applications in order to move data. This decreases the quality of performance.

If the server needs:• Multiple storage units, such as HDDs,
SSDs & other storage mediums.• More ports for connecting hard drives• High-speed data transfer between
the system and the drives• Better volume management• Pre-caching of active datablog.memory4less.com
