Unfortunately, the user currently has to put together elaborate spreadsheets to do actual pricing comparisons. This is extremely cumbersome, yet necessary. One user we interviewed created multiple pages of spreadsheets, and in the end found that of the three SRM vendors under consideration, the one offering server-based pricing ended up being the most cost-effective in the long run. But server-based pricing is not always the best way to go: Some vendors charge by CPU and others by logical partitions. Depending on how the server environment is configured (host with multiple CPUs, blade-based, virtualized processors, etc.), the server-based model could become extremely expensive.
So what is the best answer? From a user perspective, there really isn't one. But users would certainly entertain options that simplified one-to-one comparisons and allowed them to better understand costs as the storage under management increases. Today, a number of vendors propose mixed pricing models, charging by the port for SAN infrastructure management platforms, by server or capacity for SRM (file analysis) modules, and by server for application and performance analysis modules. While users support the per-port model for the base SAN management platform, for the most part they are opposed to capacity-based pricing in principal, but realize that its simplicity may make it the best choice in the end.
While we don't expect this issue will go away this year, we do believe vendors will be proposing new pricing approaches that may ease the pain. Bundling multiple applications together with one common pricing schema would be very beneficial. We would also advocate bundling in maintenance and support, which would help users understand the true cost of implementation. The big question is, what should pricing be based on? Again, while end users are in theory opposed to capacity-based pricing, that may be the most straightforward option. However, it would be interesting if vendors proposed unique models. Sun moved to employee-based pricing for their enterprise management solutions; perhaps that model would be a straightforward alternative. Regardless, something has to change: Storage administrators have enough headaches already.
