A Living TCO Model

As promised in the previous posts we have put together a TCO analysis doc and also a spreadsheet to play with:

TCO Analysis Document (TCOAnalysis)

An overview of the elements one needs to consider when putting together a TCO model. The elements in this document were garnered with the help from the wider storage community and creative professionals. The content under those elements is our work and we hope to have avoided FUDlike comment.

TCO Spreadsheet (Disk Vs Tape TCO v2.1.1 2009 (version 1))

Open to scrutiny and allows the user to enter their own values. We have only put in one tape library that has been spec’d to grow at 50TB p.a as, surprise surprise, we have been unable to get accurate pricing on a solution like the Scalar i2000 which can scale to 4500 tape slots (just under 5PB). If anyone out there has that pricing and can plug it in please do so and report back here in the comments.

In the spreadsheet we have place holders for showing the benefit of having the data available online and available. When you start to input the manual costs of retrieving content the TCO swings further towards clustered disk.

The View From OM

Please take these docs, scrutinise them, love them, hate them, change them, share them, add products and pricing. It is one way as a community we can create a living TCO model.

Being a vendor of disk based solutions we are of course confident the numbers will stay in favour of disk. We more than happy to have a conversation around this subject and potentially walk through the documents in order to ensure you get the best out of them for your needs. Get in touch!
