I went to a computer store and the salesman sold me a SATA cable and told me that all SATA cables are the same. Another salesman at a different store told me a cable rated for SATA 2, which I bought, MIGHT work as well as one rate for SATA 3 but it is not guaranteed. I decided to run a speed test on my SSD drive to check the results.
I can verify from dmesg and /var/log/messages analysis that I am connected a 6.0gbps. Are my results consistent with that type of connection?
i purchased, what was labeled as a 4-port fast ethernet sbus card from ebay.
i installed it in my ultra1, and it seems to be working fine. how can i determine if the card is infact a fast ethernet card vs. the standard ethernet 4-port card? (7 Replies)
I am trying to find a command to return the "link" speed of the networks installed on AIX.
ifconfig - gives me where the link is up and the duplex setting. I need to determine for example if the ethernet connection is 10, 100, 1000 Mbs or what the current speed is based on the network media... (3 Replies)
Hello,
I have a Supermicro server with a P4SCI mother board running Debian Sarge 3.1. This is the "dmidecode" output related to RAM info:
RAM speed information is incomplete.. "Current Speed: Unknown", is there anyway/soft to get the speed of installed RAM modules? thanks!!

Hi guys
I have a bunch of x4100's x4140's etc with solaris 10 update4 running on them but I suspect that when a lot of these boxes were originally built, the jumpstart process used an update2 miniroot, now as far as i understand it, the miniroot used at jumpstart is the miniroot that stays on... (1 Reply)

Hello
I've got a server with multiple NICS. In a script I want to log the outbound interface. Is there an easy way I can do this so that the output looks something like this:

Obviously, getting the host is simple with hostname. But how... (4 Replies)
Being a novice user to linux i m little unaware of how would i check disk read write speed.
One of my mate is suggesting to create a file using dd command and check how much time it takes to create a 30 gb file .
I think this has a little sense however i would also like to take your reviews... (5 Replies)
Hello all,
I have a question about what you think the best practice is to determine what region you are running on when you have a system setup with a DEV/TEST, QA, and PROD regions running the same scripts in all.
So, when you run in DEV, you have a different directory structure, and you... (4 Replies)

- ARC-1680 PCI Express 8 Port SAS RAID Controller
- ARC-1680LP PCI Express 8 Port SAS RAID Controller
- ARC-1680i PCI Express 8 Port SAS RAID Controller
- ARC-1680x PCI Express 8 Port SAS RAID Controller
- ARC-1681 PCI-X 8 Port SAS RAID Controller
These controllers support RAID levels 0, 1, 1E, 3, 5, 6, and JBOD using either SAS or SATA II drives.
arcmsr supports management and monitoring of the controller through the bioctl(8) and envstat(8) commands.
Please note, however, that to use some features that require special privileges, such as creating/removing hot-spares, pass-through disks or
RAID volumes will require to have the password disabled in the firmware; otherwise a Permission denied error will be reported by bioctl(8).
When a RAID 1 or 1+0 volume is created, either through the bioctl(8) command or controller's firmware, the volume won't be accessible until
the initialization is done. A way to get access to the sd(4) device that corresponds to that volume without rebooting, is to issue the fol-
lowing command (once the initialization is finished):
$ scsictl scsibus0 scan any any
The arcmsr driver will also report to the kernel log buffer any error that might appear when handling firmware commands, such as used by the
bioctl(8) command.
EVENTS
The arcmsr driver is able to send events to powerd(8) if a volume or any drive connected to the volume is not online. The state-changed
event will be sent to the /etc/powerd/scripts/sensor_drive script when such condition happens.

The arcmsr driver first appeared in NetBSD 5.0.
