I don't believe that is correct. LSI acquired 3ware, and Avago acquired LSI.

I use RODBC and RpgSQL quite a lot to access files stored in another machine under PostgreSQL. Since I am now using files which do not fit into R's memory, I would like to take random samples. What I would like is to issue a query such as SELECT * FROM file WHERE runif > 0.9 with "runif" being a uniformly distributed random number, generated on the fly; but I cannot

Greetings. Here is sample code, with some comments. It shows how I can simulate data and estimate glm with binomial family when there is no individual level random error, but when I add random error into the linear predictor, I have a difficult time getting reasonable estimates of the model parameters or the variance component. There are no clusters here, just individual level responses, so

LSI/Avago?s web pages don?t have any downloads for the SAS2308, so I think I?m out of luck wrt MegaRAID. Bounced the node, confirmed MPT Firmware 15.10.09.00-IT. HP Driver is v 15.10.04.00. Both are the latest from HP. Unsure why, but the module itself reports version 20.100.00.00: [root at r1k1 sys] # cat module/mpt2sas/version 20.100.00.00 On 2016-05-25, 3:20 PM, "centos-bounces at

I've got a 1Tb USB disc that appears to be dying - eg it took about 10 days (!) to run 'badblocks -nsv /dev/sdc' and it only did less than 2% in that time. Read access became _really_ slow. So there's definitely something amiss and I've got it offline. There's no drama about the content as I have other backups and I'm resigned to junking the thing, but I'm curious

I've seen similar cases where a USB drive appears to fail but the SMART reports success. The most recent was a 500 GB disk which had internally a Seagate Barracuda SATA drive. It appeared to work well until I sent it a largish (7GB) tarball. As well as SMART I ran a surface check and exercise, all passed. The tar kept failing. I can't test further, the disk has been broken up for

Hi, We are running Centos 6.7 - 2.6.32-573.22.1.el6.x86_64 on a Quanta Cirrascale, up to date with patches. We have had a couple of instances in which the hard drives have become renamed after reboot (e.g. drive sda is renamed to sdc after reboot). One time this occurred when we rebooted following the installation of a 10GB NIC card, another time after we tried to install mellanox drivers
