Title: Mylex RAID cards
Recently there has been some discussion pertaining to hardware RAID controllers and various people (myself included) have recommended the Mylex ExtremeRAID.
I do want to mention that if you are considering this (or other Mylex) card, keep in mind that the driver is a g
Title: FW: ExtremeRAID 1100 benchmarks
I had a 2 channel 1164 in a dual 450 PIII (256MB ram) with 4 18GB Seagate LVD 10K RPM drives in RAID 5. WIth all defaults, except 4K block size of the ext2 file system, I got about 22MB/sec reads and writes according to Bonnie. Best I remember, the 4K blo
Title: RE: Ribbon Cabling (was Re: large ide raid system)
You may be thinking of differential SCSI which uses a balanced (and twisted) pair for each data and signal line. In the old days, there was only one flavor of differential, and it was popular at least on Hewlett-Packard 800 series syste
Title: RE: Request for Advice
Watch Out!
Not many hot-swap drive enclosure vendors support ultra2 (low voltage differential). Many have limits of only a couple of LVD devices per bus, if they support it at all.
Check out Adjile Systems for a LVD drive can. Note: I have no association with A
Title: RE: DPT Linux RAID.
Carefull on this! There are two EATA drivers. It's been several months since I was trying this driver, but I believe the correct one is simply called EATA. The ones *not* to use are called eata_dma and eata_pio. I got this bit of info from the authors of the drivers
Title: RE: Hardware RAID
I concur. The Mylex seems to give excellent results under linux. I don't think the MegaRAID is hampered by a slow processor, though. This card seems to be a good performer under NT, so it may be in the linux driver. Mylex has (had? - I haven't checked for a while)a whi

I'm an idiot. After digging for ways to make outlook look at obscure mail headers like "X-loop:", I noticed what should have been obvious: Mail to the linux-raid list comes addressed to [EMAIL PROTECTED] I hate it when I make a simple problem complicat
Title: To whoever maintains this list
Would it be possible to have something like [linux-raid] prepended to the subject for mail sent from this list? That would allow people to use their mail-reader's rules to file linux-raid email into a seperate folder if desired. I do this with the other ma
Title: FW: Dream RAID System
Hardware RAID does not necessarily preclude speed. I put a Mylex extremeraid 1164 (32MB cache, 2 channels) in a dual 450MHz P3 connected to 4 18GB 10K RPM seagate wide low voltage differential SCSI disks in a raid 5 config and got about 22 MB/sec reads and writes a
Title: RE: partition size limit
I have tried the DPT SmartRaid IV card (680X0 CPU, if memory serves) and it is a DOG performance wise. Using 4 18GB Barracudas (10k RPM) in RAID5 under Linux or NT I get about 3 MB/sec writes and 8 MB/sec reads.
I have seen much better numbers from the Mylex 9
