Adjust CPU power in 1 watt increments

Filed under: General — Tags: — Nate @ 2:09 pm

Saw this over at the AMD blog recently, certainly sounds pretty neat, the ability to control the power usage of your CPU on a per-watt basis, which is significantly more effective than current power limiting strategies available today.

Well, let’s say that you have a maximum power draw on your fully configured server of 300W, and you have 42 slots in your server.  The simple math says that you have 12.6Kw of power load that you need to be able to support.  Now, if your power budget only allows you to bring 12Kw to the rack, you essentially have 2 slots that need to be left open in the rack because you can only support 40 and not 42 servers. But, by utilizing a custom TDP, you could drop the max power that some servers could draw, bringing you in under the limit of 12Kw and still getting 42 servers in the rack.

No mention on whether or not the processor will turn off cores once you hit certain thresholds (say you reduce a 80W 12-core cpu to 60W of power, it may be better to run fewer cores with higher clock speeds than more cores on lower clock speeds depending on the workload).

Oracle picks up Pillar

Filed under: Storage — Tags: , — Nate @ 1:56 pm

Most people have been expecting this for a long time, and have wondered why it didn’t happen sooner, with Oracle ditching HDS as an OEM partner almost immediately after acquiring Sun.

I have read, and heard over the past year that Oracle has been for the most part destroyed in the storage market (servers doing badly as well) as a result since their Sun storage products just are not competitive. Many larger customers have been leaving to the likes of HP and IBM who could offer the “one stop shop” for servers and storage (even before HP bought 3PAR, HP had and still has their OEM’d HDS equipment).

In some informal talks with some HDS folks last year they seemed quite happy that Oracle was no longer an OEM, saying that the people over at Sun/Oracle weren’t competent enough to handle the HDS stuff (*cough* too complicated *cough*), and so HDS just went in direct with most of those customers that Oracle walked away from.

Finally someone at Oracle woke up and realized there still is, and will continue to be for some time a big market for traditional SAN systems, far bigger than the market of customers willing to risk putting their data on cheap SATA controllers on servers running ZFS with high failure rates and poor performance.

So it finally happened, Oracle is buying Pillar. At first look however it really does seem like an odd scenario, from their SEC filing

The Earn-Out therefore will only be paid to Mr. Ellison, his affiliates and, if applicable, to the other Pillar Data stockholders and option holders if the Net Revenues during Year 3 of the Earn-Out Period exceed the Net Losses, if any, during the entire Earn-Out Period.

There’s no specific mention whether or not Larry is going to pay himself back for the $500M+ in loans he has given to Pillar over the years, so I suppose not. In any case it won’t be until the end of 2014 when we might discover what value Oracle has placed on Pillar. One commenter on The Register mentions Pillar’s revenue as $29M per year, don’t know where that came from though, doing some searching myself I found references to roughly $70M in revenue, to $3B in revenue (if that was the case they would of IPO’d)

I think it’s a good deal for Pillar to, they get much better validation on their products in front of customers.

I’ve gone through quite a bit of the information on the Pillar web site and to-date I have not seen anything that would make me want to buy their product, and have yet to hear any positive words coming from the people I know in the street/industry (granted my community is limited).

But it sure as hell beats anything that Oracle has been offering their customers recently, that alone may be enough to drive a decent amount of sales.

Pillar posted some updated SPC-1 numbers recently, a significant improvement over their original numbers, though nothing ground breaking from a competitive standpoint.

In other news, two early social media giants have fallen – MySpace being acquired for $35M, and Friendster re-inventing itself as a gaming site with Facebook authentication. I’d bet the infrastructure behind Myspace is worth about $35M by itself – Newscorp really wanted out!
