Triple Parity Raid
In an effort to catch up on links. Adam talks about triple parity RAID (raidz3) in an ACM queue article. When RAID systems were developed in the 1980s and 1990s, reconstruction times were measured in minutes. The trend for the past 10 years is quite clear regardless of the drive speed or its market segment:…

You’re Doing it Wrong by PHK
PHK’s You’re Doing It Wrong Think you’ve mastered the art of server performance? Think again. Would you believe me if I claimed that an algorithm that has been on the books as “optimal” for 46 years, which has been analyzed in excruciating detail by geniuses like Knuth and taught in all computer science courses in…

On Cloud Standards, Transparency and Data Mobility
I was on a panel last week talking about the role of infrastructure and “The Cloud” in online gaming (and I’m talking “fun” games, like Farmville, not online gambling). One of the questions was “What do you think about cloud interoperability and standards?”. To which I asked, “What do you mean?” “Well, what do you…

The “Cloud” is supposed to be better than the “Real”
In my weekly reading of posts around this mighty collection of tubes, pipes and cans connected by shoestrings, the thing most call The Internets™, I came across “Why we moved away from “the cloud” to a “real” server” from the fellows at Boxed Ice. They have a server metrics and monitoring service named Server Density. Their…

What I would want a “cloud” to do for me: a functional view
I was on a panel at Enterprise 2.0 yesterday about “Cloud Computing” providers and wanted to take the entire definite of “what is cloud computing?” from a different perspective. As a consumer, I fundamentally want the entire technology stack for an application to Just work Just scale Just tell me everything Just works means that…

Cloud Computing is actually Transparent Computing: there’s shouldn’t be anything cloudy about it
A little over a year ago Joyent was identified in a Forrester report as one of ten “Cloud Computing” companies to watch. The report was really the beginning of “Cloud Computing” being applied to those of us doing infrastructure and I think marks the point in time when the term really began to appear in…

Part 3, On Joyent and Accelerators as Cloud Computing “Primitives”
In the previous part of this series we ended by talking about 6 “simple” utilities that software uses on “servers”. They were 1) CPU space 2) Memory space 3) Disc space 4) Memory bus IO 5) Disc IO 6) Network IO Along with their natural minimums (zero) and maximums. Providing compute units that do these…

Part 2, On Joyent and Cloud Computing “Primitives”
In the first part of this series I made a key list of some of the underlying ideas at Joyent, that we believe that a company or even a small development team should be able to: Participate in a multi-tenant service Have your own instantiations of this service Install (and “buy”) the software to run…
