4. What are
Storage
Controllers?

5. 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.

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

8. 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.

9. 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.

Performance of
Storage
Controllers

13. 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.

15. 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.

16. DATA BUS
Previously, 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).

17. 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.

18. AUTOMATED
TIERING
Automated 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.

19. WHEN DO YOU
NEED A STORAGE
CONTROLLER?
blog.memory4less.com

20. 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 data
