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!!
Regards :)... (0 Replies)
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:
host(xxx.xxx.xxx.xxx): Opening connection to ...
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)

IOPING(1) User Commands IOPING(1)NAME
ioping - simple disk I/O latency monitoring tool
SYNOPSYS
ioping [-LCDRq] [-c count] [-w deadline] [-p period] [-i interval] [-s size] [-S wsize] [-o offset] device|file|directory
ioping -h | -v
DESCRIPTION
This tool lets you monitor I/O latency in real time.
OPTIONS -c count
Stop after count requests.
-w deadline
Stop after deadline time passed.
-p period
Print raw statistics for every period requests.
-i interval
Set time between requests to interval (1s).
-s size
Request size (4k).
-S size
Working set size (1m).
-o offset
Offset in input file.
-L Use sequential operations rather than random. This also sets request size to 256k (as in -s 256k).
-C Use cached I/O.
-D Use direct I/O.
-R Disk seek rate test (same as -q -i 0 -w 3 -S 64m).
-q Suppress human-readable output.
-h Display help message and exit.
-v Display version and exit.
Argument suffixes
For options that expect time argument (-i and -w), default is seconds, unless you specify one of the following suffixes (case-insensitive):
us, usec
microseconds
ms, msec
milliseconds
s, sec seconds
m, min minutes
h, hour
hours
For options that expect "size" argument (-s, -S and -o), default is bytes, unless you specify one of the following suffixes (case-insensi-
tive):
s disk sectors (a sector is always 512).
k, kb kilobytes
p memory pages (a page is always 4K).
m, mb megabytes
g, gb gigabytes
t, tb terabytes
For options that expect "number" argument (-p and -c) you can optionally specify one of the following suffixes (case-insensitive):
k kilo (thousands, 1 000)
m mega (millions, 1 000 000)
g giga (billions, 1 000 000 000)
t tera (trillions, 1 000 000 000 000)
EXIT STATUS
Returns 0 upon success. The following error codes are defined:
1 Invalid usage (error in arguments).
2 Error during preparation stage.
3 Error during runtime.
EXAMPLES
ioping .
Show disk I/O latency using the default values and the current directory, until interrupted.
ioping -c 10 -s 1M /tmp
Measure latency on /tmp using 10 requests of 1 megabyte each.
ioping -R /dev/sda
Measure disk seek rate.
ioping -RL /dev/sda
Measure disk sequential speed.
