Exotic Russian rock CAME FROM OUTER SPACE

It's obviously an alien data storage device. Has anyone searched for a pattern in these crystals? If we can decode the pattern, we might even find that this is a box set of an alien soap opera. I hope they haven't lost the big finale from the last episode.

Terrible Internet Performance

It's a shame that performance over the internet using the supplied application on my Mac is terrible though. It is ten times faster for me to transfer files using Skype than to let them slowly dribble over from my Pogoplug. If I want to share files with anyone else, they have to sign up for a mypogoplug account which is why I haven't bothered with that idea.

RIM BlackBerry Curve 3G 9300

WTF?

Maybe yours is a duff one?

I never have any trouble with the WiFi on my Bold 9700, so maybe you've got a duff BlackBerry? Have you tried switching it off and on again? ;-)

Isilon bellyflops into Smart Pools

Alistair Stewart
Terminator

RTFM and it all becomes clear (IMHO)

Now when you want to add a new disk type or node type, you can add it to the _existing_ cluster so long as you add a minimum of three nodes of that type. You still have a single filesystem and you can still access any file from any node. If one pool of storage fills up, provided you have not unchecked the box, the data will spill over into another pool. It's up to you where you tell the cluster to put the files and when, and it's also up to you to make sure you have enough capacity in that pool if you don't want it to spill over. It is still one cluster, not many, and it is still managed as a single cluster from a single GUI (not click 'n launch). You cannot build a new cluster and link it because that would be two clusters and you can't join two Isilon clustered filesystems together.

Even if you're not using SmartPools for tiering, you can use it to improve your data protection. In a large cluster of 80 nodes, for example, you might like to set protection to n+3 (or more) as the likelihood of another node failing whilst one is down is is higher than in a small cluster of 20 nodes. With SmartPools you can split it up into four pools of 20 nodes and set the protection level to n+2 (per pool), which would use less space for protection and give a higher level of protection.

Spellchecker strike

This paragraph seems to have suffered from an over-ambitious spellchecker:

Smart Pools have the different S-Series, X-Series and NL-Series nodes grouped or clustered together and linked by InfiniBand, Isilon's backed storage link…

Should read "Isilon's backend storage link"

It all sounds like just what the storage world has been waiting for, doesn't it.

Sony don't have a monopoly on crashing

I updated my previously reliable Tomtom Go 510 at the weekend and now it crashes regularly - three times in a single 20-mile journey. At least it carries on once it has rebooted, but it is still a pain while I wait for it to return from its latest bout of narcolepsy.

New 3D chip transistor may reach 50GHz

Chips are made of smoke and spiders

I have heard rumours that there has been a breakthrough in smoke technology, so perhaps they're packing higher density smoke into these transistors. I wonder if that will make them as volatile as Dell laptop batteries?

Mars: more evidence of a watery past

Mr Spock Explodes with Emotion

What's this, "explosive vulcanism"? Did the Vulcan empire colonize Mars and then have a war over the dwindling water resources?

Perhaps it should read, "explosive volcanism"?
