Enterprise Computing: Vendor Guarantees

My previous post regarding HDS and 3Par’s savings guarantees generated a few replies and rather than respond in comment, I’ve written an additional post in case I rant on too much. First thought: vendor guarantees need to be genuine; no hiding behind obtuse configurations that help to fluff the figures, or restrictions on the type of data suitable for reduction. ...

Enterprise Computing: 3par and HDS – 50% Saving – Guaranteed?

In the past week, both 3Par and HDS have announced a 50% guarantee on reclaimed storage if customers move data from existing “fat” legacy arrays to 3Par storage or use HDS thin provisioning technologies.  The 3Par news release is here; the Hitachi news release is here. The 3Par guarantee is presented with a caveat: The above is intended to highlight ... Read More »

We all know that over time, Thin volumes transition back to Thick volumes as data is created ... Read More »

Enterprise Computing: The Wide Striping Debate

I’ve read with interest this week the posts on wide striping and the consequent expansion to thin provisioning.  Here are some of the highlights: First there’s Martin Glasborow’s post, which discusses whether wide striping and thin provisioning should be chargeable items.  I’d go a step further than Martin and suggest that thin provisioning (TP) should also be free; after all, ...
