I spent last week tying up loose ends before Tech Field Day 5 in San Jose. It’s going to be a great event, with presentations by Symantec, Drobo, Xangati, NetEx, InfoBlox, HP, and a new company making their US launch! In the mean time, I am working hard to wrap up the Small Enterprise Storage Array Buyers’ Guide for DCIG and continuing my regular work – spreading the word about state of the art IT! I’ve been researching VMware extensively, and building a home lab server, in preparation for my Storage for Virtual Servers seminar, too.

Eleven Tech Trends To Watch In 2011
Prognostication is a perilous business, but pundits are drawn to the topic in the month of December. The fact that most predictions fall on their faces demonstrates the intoxicating mix of hope, dreams, and irrationality that mark both geniuses and fools. I am neither, so I like to make predictions after the fact! But this year I’ve been asked to look to the future, so I’ll stick with the safe road and pick current trends rather than guessing what I hope will come.

Wrapping up this week, here are my shared items.
The Four Horsemen of Storage System Performance: Never Enough Cache
Perhaps the previous discussion of spindles left you exhausted, imagining a spindly-legged centipede of a storage system, trying and failing to run on stilts. The Rule of Spindles would be the end of the story were it not for the second horseman: Cache. He stands in front of the spindles, quickly dispatching requests using solid state memory rather than spinning disks. Cache also acts as a buffer, allowing writes to queue up without forcing the requesters to wait in line.
The Four Horsemen of Storage System Performance: The Rule of Spindles
Why do some data storage solutions perform better than others? Mechanical performance, RAM caching, I/O capacity, and the intelligence of the system all have a part to play. Today we examine the rule of spindles: Adding more disk spindles is generally more effective than using faster spindles.
