Finding the right storage devices for your business or domestic needs can be problematic, whether you’re struggling to balance cost with the amount of capacity you expect to need, or unable to decide on the right data storage array. For some people, choosing between modular and monolithic storage is incredibly difficult. Each type offers its own advantages and disadvantages, and will appeal to people for various reasons. Understanding the difference between the two types can be quite a challenge, given the complexity of their design and performance, but at eProvided, we’re here to help you make sense of all things storage and data recovery – we’re going to explore the basics of modular and monolithic storage, to help you make a more informed choice.

Modular Storage

Modular storage arrays are typically based on two controllers, which are kept apart from the unit’s disks. In essence, this ensures that, if one controller experiences a failure, the second will take over from the first automatically. These are held on a shelf which runs on a separate power source to the disks. Also, they’re connected via cables (usually copper or optical). One of the key advantages of modular storage is that it’s cheaper than monolithic storage. Therefore, they can be expanded over time. You may want to start with a single controller and one housing disks. You can then add more than your needs dictate, until you reach optimum capacity.

Generally, smaller locations with low storage demands begin with low-capacity modular storage devices. This is more cost effective. Later one can expand as the budget allows and your data needs demand.

In general, modular storage is usually up to 25% cheaper than monolithic devices. These tend to offer interfaces designed for user-friendliness & easier capacity-expansion. Thus reducing the need to make calls for technical assistance.

Monolithic Storage

Unlike modular storage, monolithic is based on disks fixed into the array frame and linked to the various controllers via massive amounts of cache memory. These offer helpful redundancy features, so that any failures are immediately compensated for by another – thanks to this design, monolithic storage rarely fails.

With plenty of cache memory (shared among any linked devices), these offer greater storage capacities than modular arrays, and are typically equipped for better data-management. The more cache memory your storage device has, the faster and smoother it will run. These typically boast the better service and support of the two, and their proven disaster-recovery appeals to many businesses – you may be more willing to pay for long-term reliability (if your budget allows).

Making the Choice

Having taken a brief look at modular and monolithic storage, which is right for you and your needs? The choice, of course, is down to you – cost will certainly be a factor, and easy-expansion may be a priority, too. Depending on the size of your business or department, you may find that modular storage is the best all-round choice for its cost-effectiveness and user-friendly design; on the other hand, the additional cache memory and reliability monolithic options offer may just swing it for you. There is no right or wrong answer – just weigh up the pros and cons of each and compare these to your business needs.
