Data Storage Subsystems

We sell, install, and support a range of storage subsystems that preserve your valuable data and improve the overall performance of your mainframe systems.

We recommend IBM Shark disk subsystems for enterprise storage.  The best values are used machines that have been tested and certified for maintenance by IBM.  The features, compatibility, and quality of Shark subsystems make them a top choice for mainframe users migrating from systems with built-in storage, such as the 7060 Multiprise 3000, to more advanced processors like the z800 and z890 that require external storage.

We are happy to review your current requirements and likely expansion paths so you can get the very best and most economical Shark equipment for your particular situation.

The easiest way to get on the path to a great Shark value is by sending us a sketch of your requirements.  We've got a simple web form to help you do this right here.

Reliable Computer Sales, LLC, can help you understand the full range of storage options available to you whether you are bringing in a new subsystem or increasing the functionality and capacity of equipment you already have in place.  If you sketch out your current situation and how you want to change it, we'll do the research and get back to you with choices, technical details, prices, and any other facts you might want on hand before making a decision.
