On my C5 machine (a Dell XPS420) I have a 500Gb disk on the internal SATA controller. I also have a SiI3132 dual-port multi-device eSATA card. This is connected to an external SATA array of disks. Now occasionally I see something like this in my logs ata7.01: exception Emask 0x0 SAct 0x0 SErr 0x0 a ction 0x0 ata7.01: irq_stat 0x00060002, device error via D 2H FIS ata7.01: cmd

Hi, this says that opensolaris only requires 512MB ram: http://dlc.sun.com/osol/docs/content/IPS/sysreq.html This says 1GB ram and a 64bit processor are recommended: http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#Memory_and_Swap_Space Am I going to have problems if I run opensolaris and zfs at the minimum requirements? -- This message posted from opensolaris.org

I'm looking at buying a NORCO DS-1220 and it comes with a NORCO 4618 PCI-X card (4 port eSATA, with a port multiplier on the card or the chassis). I've been trying to pin down whether or not CentOS will see all 12 drives, and I haven't seen anything that is definitive. I see that the kernel module sata_sil24 supports the SiI3124 chip on the NORCO 4618 card, but I haven't found

Hi all, Space is starting to get a bit tight here, so I''m looking at adding a couple of TB to my home server. I''m considering external USB or FireWire attached drive enclosures. Cost is a real issue, but I also want the data to be managed by ZFS--so enclosures without a JBOD option have been disgarded (i.e., I don''t want to use any internal HW RAID controllers). One

Tired of "little problems" trying to keep 7 drives working in an old desktop computer, I'm considering an external SATA drive enclosure with a controller card based on the Sil3124. http://www.ipcdirect.net/servlet/Detail?no=152 I'm a bit concerned about long-term support, namely that the company's driver page only lists drivers through RedHat 4.

A little back story: I have a Norco DS-1220, a 12 bay SATA box, it is connected to eSATA (SiI3124) via PCI-X two drives are straight connections, then the other two ports go to 5x multipliers within the box. My needs/hopes for this was using 12 500GB drives and ZFS make a very large & simple data dump spot on my network for other servers to rsync to daily & use zfs snapshots for

Hello, I am new to open solaris and am trying to setup a ZFS based storage solution. I am looking at setting up a system with the following specs: Intel BOXDG33FBC Intel Core 2 Duo 2.66Ghz 2 or 4 GB ram For the drives I am looking at using a LSI SAS3081E-R I''ve been reading around and it sounds like LSI solutions work well in terms of compatability with solaris. Could someone help

Now the test for the Vertex 2 Pro. This was fun. For more explanation please see the thread "Crucial RealSSD C300 and cache flush?" This time I made sure the device is attached via 3GBit SATA. This is also only a short test. I''ll retest after some weeks of usage. cache enabled, 32 buffers, 64k blocks linear write, random data: 96 MB/s linear read, random data: 206 MB/s linear

Hi there! we are thinking of deploying a IPSEC VPN concentrator using multiple PCI bus version VPN1401 cards in a FreeBSD box using hifn support.. From the technical specs in Soekris website http://www.soekris.com/vpn1401.htm, each card can support 24 to 70 connections. The question is if we put 3 VPN1401 cards in a single box, does this mean the FreeBSD box can support 3 x (24 to 70) IPSEC

I''m playing around with ZFS and want to figure out the best use of my 6x 300GB SATA drives. The purpose of the drives is to store all of my data at home (video, photos, music, etc). I''m debating between: 6x 300GB disks in a single raidz2 pool --or-- 2x (3x 300GB disks in a pool) mirrored I''ve read up a lot on ZFS, but I can''t really figure out which is

So after toying around with some stuff a few months back I got bogged down and set this project aside for a while. Time to revisit. <BR><BR> Looking around there still is not a good "these cards/motherboards" work list. the HCL is hardly ever updated, and its far more geared towards business use than hobbyist/home use. So bearing all of that in mind I will need the

Dear R users, I have more of a statistical/econometric question than straight R one. I have a data set with the discrete hazard rate of small firms survival on 400 counties over a period of 9 years. This data was generated using census information from the VAT registration number of each one of these business. I would like to analyze the effect of regional factors (deprivation index, real

I cannot remember if this has already been discussed or not, and I'm a bit worried I'm throwing off an endless debate. If it's already settled, no need to discuss it further. TOPIC #1: Shouldn't R use KB, MB and GB when reporting on sizes kilobytes, megabytes and gigabytes? More specifically, format() for object_size objects (returned by object.size()) uses Kb, Mb and Gb, which

Hi, i have two servers, connected to to the lan by 10Gb with 10Gb and DAS hardware raid. Each system con read and write locally or to the 10G iscsi by more than 200 MB/s. Now I have to transfer backups form A to B and doing this with rsync always stuck at +- 48-50MB/s no matter which options, compressions, encryption etc I use. Even the plain default rsync is at that 50 Mb limit. coyp by scp

Using File.size(myfile) I can get the size of the uploaded file in _bytes_. Does anybody know of a function to convert bytes into a more human readable format? If I had a wish list for a "file_size_in_words()" function, it would do this: 10752 bytes becomes "10.5 Kilobytes". 2213814 bytes becomes "2.1 Megabytes". 238 bytes becomes "Less Than 1 Kilobyte".
