Dell VPLEX vs. IBM DevOps Code ClearCase

This works in two fold. First it creates a copy of the data in two locations, protecting the data from a SAN or a NAS failure. Second, it provides a data point in a second location that can be used as storage for a stretched virtual cluster, giving a virtual stack a means to continue operation.

IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control

• Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
• Rational ClearCase handles parallel development of many dependent applications really well.
• The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.

• Requires high bandwidth low latency connectivity between sites.
• Cost wise it is expensive because you have to purchase with a mirror in mind.
• Configuration can be difficult.

When this was purchased there was no other product that could achieve what we were looking for, now this feature is pretty standard with storage platforms. It is a costly solution not just the hardware but the infrastructure to support it. It requires a connection between sites with at least 3 gigabytes per second and sub 5 millisecond latency and a network infrastructure capable of handling that

If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.
