Busy day today. Jeff came in and found the server closet air conditioner went dead around 5am. So the entire closet was running pretty hot. Turns out there was another coolant leak (a problem we seem to deal with a lot). At any rate, this was fixed pretty quickly and everything cooled up to 2 degree colders than before this weekend. Problems over the weekend. The mysql replica lost its connection - a known, common problem (hopefully will be fixed once the replica is on the same switch as the master db). I discovered that and gave it a kick. Hours later the upload server needed a kick as well. Eric discovered that in the morning and got it working again. We're also fairly pegged at our network limit again, I think thanks to the workunit turnaround time being pretty low (i.e. fast). Plus I have to send extra raw data to our archive over the same link. Oh well. Expect data transfer headaches for the next qwhile. I also am planning for our last OS upgrade tomorrow on jocelyn, the master mysql database server. This means, like when we upgraded bruno, an extra long outage tomorrow. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Thanks for the heads up on the longer than normal outage. Of if the coffee machine is in the server closet it is just an attempt to see why you have all those coolant leaks. Don't pay it any attention. :) Gary |

....but it would be nice, to get those informations over the frontpage as a RSS-Feed. |

Just a naive suggestion, since I guess you already considered this: You pay for a 1Gbit/s connection, but you can use only 100Mbit/s due to local infrastructure. Why don't you set up some (at least one) WLAN connection with directed antennas between your building and a place where you can use that fast connection? This way you could use a load balancer to make it a single, but faster connection or you can transfer the raw data over the wireless link without affecting normal operation. |

Just a naive suggestion, since I guess you already considered this: I think there are two problems with that. One is it costs a pile of cash they don't have. Second I think the path length between Palo Alto and Berkley is a bit long. |

Just a naive suggestion, since I guess you already considered this: The distance can likely be dealt with, but it comes back to money. The farther you go, the more expensive the wireless devices. The earlier post said "WLAN connection" and we have to remember that the "L" is Local. |

Just a naive suggestion, since I guess you already considered this: Quite, and 30 miles over the bay isn't local. The other thing is we must remember bandwidth. If the point is to send a Giga bit bandwidth signal that will require a lot more than a wireless router! The good thing is SSL is up the side of a hill and it does look out in the direction of Palo Alto. At PAIX I'm sure some sort of antenna tower would be required to get line of sight. Nothing too outrageous but still that requires permission of the landlord, PAIX's permission, building permits maybe even a zoning hearing. Never mind the FCC licenses. As for the installation likely something on the order of a six or eight foot dish at each end so you would still have good signal while the bay is full of fog. In any case this isn't going to happen unless a telephone company donates surplus equipment from a microwave link and a crew to install it and maintain it. Gary |
