A brief about Oracle Unified Storage

Oracle has made fantastic innovation in the field of unified data storage with hybrid storage pools and storage management tools.

A. Hybrid storage pools

This technology is combination of flash drives, HDD and Oracle’s ZFS.  ZFS adds to the performance. Flash drives gives advantages in terms of:

1. Performance:

As they provide thousands to lakhs of IOPS (Input/Output Operations Per Second).

2. Low power consumption:

As they do not have any moving parts, the power consumption is a mere fraction of what HDD actually consumes. Thus they use around 13 percent of power when they are in use and almost negligible when they are ideal.

3. Lowers costs:

Although HDD is cheaper than Flash drive but with a cost measured in IOPS, Flash Drive is a lot cheaper than HDD.

4. Higher reliability:

Flash drive has a life of around 1.85 million hours compared to 1.3 million hours for HDD.

B. Oracle Solaris ZFS

ZFS is one such technology that has reduced data management errors to a considerable extent. It uses following techniques to achieve this:

1. Virtual storage pools

Oracle uses single volume manager and more over uses a virtual file-system architecture to access physical drives. Thus this makes addition and removal of physical drives from the pool very efficient without causing any data loss. All of this is possible due to the virtual memory addressing scheme implemented in a physical environment.

2.  Data integrity

ZFS uses some new techniques to make sure the data on disk is kept secure. Here it uses COW (Copy On Write) technique, wherein the data is first written on the disk and then the pointers to the data are updated and write is committed. Also continuous data check is carried out to maintain data correctness and replace it with the mirrored one if some error occurs. This helps in faster replication of secured data and also is an efficient way to protect data against any major corruption.

3. Solid performance

All these features add to the performance of the storage. The intelligent resource pool manager immediately starts to address any new block added to the pool. Also data is evenly distributed all over the pool to sustain higher IOPS and increase throughput.

Benefits Of Oracle Unified Storage:

Oracle Unified Storage is the ideal choice for any organization looking to reduce its storage costs without compromising on performance. Ideal for running applications like:
A. Virtualization
B. Database servers
C. Cloud storage
D. Online gaming servers
E. Live Video streaming services
F. DR services
G. Applications that require large amount of computing capabilities

How to deploy Oracle Unified Storage:

Oracle takes extreme measures to deploy its technology without causing any downtime.  The storage comes with pre-installed software like  pre-configured storage pools, hardware, network with proper ports enabled and  ready to go NAS feature.
As data migration is one of the most critical and time consuming task, Oracle ZFS asks the users to set “shadow migration” for a drive. Once shadow migration is set, users can perform read/write operations on their respective drives and migration process is enabled in background with proper care to avoid data loss.


Finally, I have tried to include almost all the important points that should give you a brief idea about unified storage and their benefits over traditional ones. Though you will have to do some more brainstorming to get one under your roof. There is a lot of information available on the Internet with proper comparison charts to help you find the best deal for your requirements.
