Storage service in the clouds!

Cadatasoft

Our company provides IT services in a variety of fields. Our primary strengths are in the fields of Storage Networking (SAN) and Cloud computing (Salesforce) development. We would like a logo to a depiction of both these offerings as well as a new planned service that would provide a cloud computing solution based on data-center storage. A sci-fi angle would be good but let that not detract from a good design if you have any in mind.

Primary audience would be IT managers, IT departments, future employees, overseas clients and other service providers.
We expect most of them will be aware of the technology that we would like the logo to represent.

The company name does not need to be represented in the logo, just the service offering.
We would like a high resolution image that can be resized or you can provide a few varying sizes if that is more practical so it can be used on letter heads, business cards, brochures etc.

Please try not to make the design too complex so it it will not look like a jumbled mess in smaller sizes.

The files we will require are:
Print file format - pdf file and png file
Web file format - .jpg and layered .psd

Please DO not use any stock images or clip art in the logo - we do not want you and 99designs to be responsible for copyright infringement.
