Glm reduced SCSI transfer rate.... how to recover?

Hi,
One of my disks gone bad, and glm driver has reduced the transfer rate to that bad disk,
and (for some unknown reasons) reduced the transfer rate to other good disks, from
40MB/s (FAST-20, wide) to 5MB/s. The SCSI box is an UltraSCSI version of MultiPack.
Now I have replaced the bad disk to a new one. However, the transfer rate is still 5MB/s.
Does anyone know how can I make them operate at full speed again?
The OS is Solaris 10 11/06. I have tried followings, but none worked.
(c2t9d0 is the attachment point to the bad disk. it now has the replaced disk.)
cfgadm -x reset_device c2::dsk/c2t9d0
cfgadm -c unconfigure c2::dsk/c2t9d0
cfgadm -c configure c2::dsk/c2t9d0
cfgadm -x reset_all c2Thanks very much in advance!

Anybody knows if the source code of scadm tool is available somewhere ? (opensolaris etc. ?)
I don't have any additional advice to offer other than asking that you to try the flash-update all over again,
one more time, as if it were the beginning again.Yes but how because the SC is not discovered anymore by Solaris :
"rmclomv: WARNING: DP_GET_SDP_VERSION failed, ret=4"
"The SC hardware could not be initialized."
Can you try to flash the mainalomfw ? Your log contained only the flash of the alombootfw !
/usr/platform/`uname -i`/sbin/scadm download alommainfw
I guess jumper JP2 allows to recover from a failed flash by selecting the un-touched half the PROM.It does not work as the SC is not responding anymore to Solaris

scadm: The SC hardware could not be initialized.

It's a pitty that obtaining OBP/ALOM updates requires a service contract. I got a V210 recently.
Unfortunately both OBP and ALOM are the intial release 4.8.2 / 1.0.I agree but it's probably also because you need support in case it fails ;-)
Thanks for your answers!

How to find the max data transfer rate(disk speed) supported by mobo?

I plan on replacing my current HDD with a new and bigger HDD.
For this I need to know the max data transfer rate(disk speed) that my mobo will support. However, dmidecode is not telling me that. Am I missing something?
Here's dmidecode:

I just checked my BIOS and my current setting is set at IDE although it also mentions that the default should be AHCI. Currently I have a dual boot of Windows 7 (need it for Tax software) and Arch
So I guess, when I get the new HDD, I will first set it to AHCI and then install the OSes on it. See if NCQ helps any, and if not I will turn it back and re-install (if I have to). I am planning to have Windows only in virtualbox in the new drive.
Anyhoo, while I was in the BIOS I found two things which I had questions about :
1) Under Onboard Devices --> Integrated NIC , my setting is currently set at "On w/PXE" and it says the default should be just "On". Would it be ok to change it back to On since its a single machine and its not booting an OS on any server. I just don't want to have to re-install anything now since I will be doing that in the new HDD.
2) How would I know whether my BIOS would support a 64 bit OS in Virtualbox? I checked some setting under Virtualization, but they weren't very clear.
I will edit this post and let you know exactly what settings were present under the Virtualization sub-section.

How can I check the data transfer rate of my FW800 port

I have an iMac 2.4 20 inch (MB323LL/A) with a Lacie external rugged hard drive (320 GB). I have attached it using my FW800 port with the cable supplied with the drive.
It seems slow to me so I was wondering if there is any way to see what the current data transfer is for a backup in progress. Of course it should be 800Mbps but is it really moving at that speed ? How can I tell what speed it is transferring at ? Can I use the same method for USB ports too ?

When you move a large file, you are more likely to see a sustained transfer rate than a small file. Small files have to be individually read/write back and forth, thus slows the actual transfer rate down. If you are moving any file up to 4 GB and probably over 1 MB you'll see more realistic transfer rates. Furthermore your hard drive access time, and RPM figures into the equation too, as well as how much RAM you have. 800Mbps works out to 100 Megabytes per second under ideal conditions.

How can I reduce the bit rate of songs in my Music Library to enable me to

At the moment i can only fit about 1300 songs on my iphone and also have used up half the space on my 120gb Classic with 7000 songs which is a lot less than what i was told would fit on. so............
How can I reduce the bit rate of songs in my Music Library to enable me to fit more songs onto my iPhone or iPod Classic.. and what is the minimum rate that i should stick to in order to retain good sound quality.

For existing tracks, see:
http://support.apple.com/kb/HT1550
For CDs you import in the future, change the Import settings in the iTunes -> General preferences.
As to what will be a good bit rate, that's going to be up to you and what quality you find acceptable, but many people find that 128 kbps AAC is the optimum balance between small file size and quality.

How to get better than 5.2MB/s transfer rate from USB 2.0 on Mac Mini

G'day,
I've got a circa 2007 Mac Mini with 1GB of RAM, running Snow Leopard. Connected to this is a USB 2.0 500GB Seagate Freeagent drive from circa 2008. As far as I know, the USB disk is free of errors.
I am trying to use dd with a block size of 1MB to transfer a 250GB file from an Ethernet mounted Time Capsule drive to the USB disk on /dev/disk1.
A dd from the Time Capsule to the /dev/null gives me a transfer rate of ~35-40MB/s. However, when the target is /dev/disk1, the transfer rate is only around 5MB/s. I checked the system profiler and disk1 is connected to the USB High Speed Bus.
Any clues on how to improve USB 2.0 transfer performance?

Fragmentation is unlikely to be an issue since I was trying to write to the raw block device with dd which is as close to a pure sequential write scenario as one is likely to encounter (e.g. no small block, random access involved)
From a Linux host, I was able to dd to a file on the disk's file system at 20MB/s.
I'll run some other tests with another disk to see whether the issue is peculiar to the disk or to the Mac's USB subsystem.

How can i improve speed of my application and reduce data transfer time ?

HT1391 how to recover itunes library after reformatting computer - has also wiped my ipod clean when I tried to transfer the music from there

Hi - I have reformatted my computer and want to know how to recover my tunes that were on itunes - I have tried to transfer the tunes from my ipod but it has wiped this clean too - any suggestions welcome!!

*If my kids dock up their iPods to charge them (the iPods still have the music on them) will the computer "sync" the iPod to the now empty library that's on the computer?*
If the iPods are set to update automatically you need to take care connecting to an empty iTunes. You can use a keyboard command to prevent an iPod auto-syncing with iTunes. While connecting the iPod to the computer on a Mac hold down the Option and Command (⌥ and ⌘ Apple) keys together. This will stop the iPod from auto-syncing with iTunes and it will appear in the source list. Wait until you are sure the iPod has mounted, and that it will not auto sync and then you can let the keys go. This may take between 20 to 30 seconds depending on your computer. You should then be able to change your settings: iTunes for Mac - Keyboard Shortcuts
Once the iPods are connected it might be a good idea to change them to manual updating at least until you have your library back in shape. The content of iTunes and the iPod are not syncronised in this mode so the two can be different, you can get details here:
Managing content manually on iPod
iPod - Syncing Music
Something else to be aware of when using an iPod in manual mode is that the "Do Not Disconnect" message will remain on the display until you physically eject the device: Safely Disconnect IPod

How to achieve the maximum file transfer rate from PXI to local host?

I will have to copy a huge amount of data (as big as 50 GB) from a PXI-8106 unit on site to a laptop. Currently it would take several hours. It is critical to max out the data transfer rate.
The standard method we've been using is just drag and drop using Windows Explorer via FTP. I tried to use FTP VIs with Filezilla Server as well but the transfer rate is only like 1.5 MB/s. Is this normal? Once I saw it was 3.0 MB/s but for some reason, that isn't happening now.
For another option, I tried to transfer data to a USB flash drive but it's even slower. As far as I know, USB 2.0 transfer rate is supposed to be around 60 MB/s but why would it be slower than 1.5 MB/s? What could be the speed limiting factor in my file transfer setup?
Any tips on improving file transfer rate would be appreciated!

Sustained 40 MB/s? That is my dream speed! The maximum speed I've ever seen here was about 25 MB/s, which is still very good, and that happened only after copying back and forth, which I explained above. Let me go through what I did with screencaps first.
These are the test tdms files to transfer in the PXI: an original file witten in the PXI and its copy file. I copied the original file from PXI to laptop and renamed it (added '_copy') and then copied it back to PXI.
FTP module is transferring the original file to the Filezilla server on laptop. Note the low speed.
FTP module is transferring the copy file to the Filezilla server on laptop. Note the higher speed.
This is the FTP sub VI I'm using. It transfers files in sub-folders (one level lower), too. The data connection is set to 'passive' on the FTP Put Multiple Files VI but it doesn't seem to make any difference. I attach the sub VI.
You tried the file transfer with a 500 MB text file. Would there be any difference if the file type was tdms? Would the RAM size matter? It is 2GB here.
And the LED is orange, which means Gigabit.
Another question: Is there any way to programmatically stop file transfer in progress? Currently, I just have to restart the PXI.
Thank you!

I resently upgraded my OS to Snow Leopard, but the information in my address book did not transfer. How can I recover the lost information?

I upgraded to Snow Loepard OS. But not all the information in the address book was transfered. How can I recover the lost information from my old address book?

No I did not make a copy of my address book.
Some information was moved over, many did not.
I do not see a pattern.
I think all the info is still on the hard drive, I just don't know how to recover it.

RAC Interconnect Transfer rate vs NIC's Bandwidth

Hi Guru,
I need some clarification for RAC interconnect terminology between "private interconnect transfer rate" and "NIC bandwidth".
We have 11gR2 RAC with multiple databases.
So we need to find out what the current resource status is.
We have two physical NICs each node. And 8G is for public and 2G is for private (interconnect).
Technically, we have 4G for Private network bandwidth.
If I look at the "Private Interconnect Transfer rate" though OEM or IPTraf (linux tool), it is showing 20 ~30 MB/Sec.
There is no any issue at all at this moment.
Please correct me if I am wrong.
The transfer rate will be fine till 500M or 1G/Sec. Because the current NIC's capacity is 4G. Does it make sense ?
I'm sure there are multiple things to consider,but I'm kind of stumped on the whole transfer rate vs bandwidth. Is there any way to calculate what a typical transfer would be....
OR How do I say our interconnect are good enough ....based on the transfer rate ?
Another question is ....
In our case, how do I set up the warning threshold and Critical threshold for "Private Interconnect Transer rate" in OEM ?
Any comments will be appreciated.
Please advise.

Interconnect performance sways more to latency than bandwidth IMO. In simplistic terms, memory is shared across the Interconnect. What is important for accessing memory? The size of the pipe? Or the speed of the pipe?
A very fast small pipe will typically perform significantly better than a large and slower pipe.
Even the size of the pipe is not that straight forward. Standard IP MTU size is 1500. You can run jumbo and super-jumbo frame MTU sizes on the Interconnect - where for example a MTU size of 65K is significantly larger than a 1500 byte MTU. Which means significantly more data can be transferred over the Interconnect at a much reduced overhead.
Personally, I would not consider Ethernet (GigE included) for the Interconnect. Infiniband is faster, more scalable, and offers an actual growth path to 128Gb/s and higher.
Oracle also uses Infiniband (QDR/40Gb) for their Exadata Database Machine product's Interconnect. Infiniband also enables one to run Oracle Interconnect over RDS instead of UDP. I've seen Oracle reports to the OFED committee saying that using RDS in comparison with UDP, reduced CPU utilisation by 50% and decreased latency by 50%.
I also do not see the logic of having a faster public network and a slower Interconnect.
IMO there are 2 very fundamental components in RAC that determines what is the speed and performance achievable with that RAC - the speed, performance and scalability of the I/O fabric layer and for the Interconnect layer.
And Exadata btw uses Infiniband for both these critical layers. Not fibre. Not GigE.

KT3 Ultra ARU Slow HD Transfer Rates

Hello,
First, please see my system information at the bottom of this message.
I have a MSI KT3 Ultra ARU motherboard and have installed a Maxtor ATA133 60GB hard drive with 2 MB cache. The hard drive is jumpered as Master and is connected all by itself on the IDE1 ribbon cable. On IDE2 I have a CDRW (Master) and a CD-ROM (Slave). My other hard drive (WD 120GB ATA100 8 MB cache) is on IDE3 and is set up in RAID 1+0 stripe.
I recently ran the Sandra file system benchmark on my hard drives with what I think are very discouraging results. My Maxtor drive on IDE1 scored 32 MB/s and my WD drive on IDE3 came in at 23 MB/s. Those are some stinky results aren’t they?
I checked my Device Manager under IDE ATA/ATAPI Controllers and it indicates that for my Primary IDE Channel the current transfer mode for device 0 is Ultra DMA Mode 6. I don’t know how to check the transfer mode on my IDE3 hard drive.
Question #1: Are my 32 MB/s and 23 MB/s results slow for my hardware?
Question #2: If these results are slow, how can I increase the transfer rates?
Please help!
Thank you!!!!

These tranfer rates seem fine for sequential read rates. The maxtor drive is at mode 6 and the WD should be at mode 5 if its ATA100.

Gigabit ethernet + TC doesn't mean gigabit transfer rates to the TC drive..

Alright.... I've spent a ton of time trying to figure this out (probably more than I should have) and I thought I'd post my findings so that either a) I'll save someone else time out there or b) someone can tell me I'm a complete moron
So I had an airport extreme. I replaced it with a Time Capsule. I have a Windows (boooo) PC connecting directly to my TC using a gigabit ethernet card (which I bought specifically connect it to the TC) so (I thought) I could enjoy gigabit transfer speeds to the internal hard drive from the wired PC. I had some fun plans of shoving my itunes directory on the TC and letting appletv sync (yes through my pc) and keeping lots of videos there, etc. Who cares - it'd be at gigabit speeds! But, in reality, things didn't quite work that way (though my itunes directory does still live on my TC...for now).
Well, I had a semi-unique situation to do some pretty massive testing because I have 2 gigabit network cards, 1 100mb network card, and a wireless-n network card and two internal hard drives - both very fast. I also tried Cat 5, Cat 5e, and a Cat 6 cable.
And here's what I (think I) figured out:
The hard drive in TC can not achieve gigabit transfer speeds. Your transfer rates will be limited by the IO to the hard drive. In fact, it can't even come close.
Using my "fastest" setup - so Cat 6, fastest internal drive, gigabit ethernet, and transferring a file exactly 1 gig in size I was able to have a sustained transfer rate of 140 megabit per second - that's 17.4 MB/s for folks not wanting to do the math (that's reading FROM the TC. Writing TO the TC dropped the speed down to 106 megabit/second or 13.35 MB/s). Going to a 5e cable knocked that down to 130 megabit a second. Putting in a Cat 5 cable knocked me down to 110 megabit a second. Switching between my two gigabit network cards did nothing. Switching my cards between two computers did nothing.
Now, just changing the above setup to use my 100Mb network card resulted in these results: 67 megabit read (8.4MB/s) and 65 megabit write (8MB/s)...
And using wireless N, I got about 10MB/s up and down.
And just as a final test, connecting my two computers together using the 2 gigabit network cards through the TC, I was able to achieve standard gigabit speeds.
SO what does this all mean?
I think the IO to the hard drive in the TC can only read at about 140 megabit/s and write at about 110 megabit/s. I'm not sure if it's the HD itself or how it's connecting to the TC - but that's why I'm not aware of anyone getting faster transfer rates to the drive in the TC (maybe you guys are?). The gigabit ports themselves are fine - and if you're doing anything from one gigabit port to another gigabit port you'll be fine.
So stop beating yourself up trying to find some elusive XP specific issue with gigabit transfer rates (though vista had a problem - shocker), or that you must have a defective gigabit card (which is why I have two cards now instead of one :)), or that your cable must be bad ("maybe my cat 5e isn't good enough?")... it's just this drive ... or how the drive is connecting to the network - can't handle the gigabit speeds.
Unless someone else out there has another explanation? Do these speeds mesh with what you're seeing in "optimal" situations? Or maybe there's just a throttle switch for goobers like me using Windows instead of MacOS!

Hi,
the interfaces available today which connect your drives integrated electronics to your computer can handle that speeds. but the drive itself is limited by the mechanical things going on in there
You can get such transfer speeds if the data you request is in the cache of the drives internal electronics for example. Some drives have 8 MB of cache memory. So if you request to read or write less than 8 mb and (in the read case) you are lucky enough to have those few megabytes cached then you may get that performance

Determining Data transfer rate through modem in java

Hi,
I want to write an application in java which will communicate with
connected modem of the system and it will detect the data transfer rate.
I want to know how much data is transferring(upload/download)through modem and in a specific time how much data is transferred.
I will give some max upload/downloading limit for a specific time and if data transfer exceeds that limit,it will show message.
e.g if i fix max upload/download data transfer limit by the modem is say 10GB/20GB for a specific time span say for 15 days.Then my program automatically will start when the Modem will be connected and keep a log of data transfer(upload/download)and if data transfer goes beyond limit then it will show message.Also i would be able to see how much data is transferred for any specific day.
I want to know this type of application is possible in java.If yes then
which API's i need to use.
If this type of program is available in some site in other language then also i will be helpful.Pl give the links.

Hi,
i want to do it in java only to explore the power of
java.I agree with Abuse, Java is not designed for such applications. I'm not even sure if you can solve your problems with Java.

How to recover photos after restoring iPod touch?

Yesterday, there was an update for the iOS 6, I believe. When I pressed the update button, a message popped up saying that there was a problem with my iPod touch 4G and that I need to restore it. I had absolutely no idea why that message would pop up in the first place because my iPod was working just fine. But I couldn't update my iPod to the newest version if I didn't do what iTunes says... so I was about to restore my iPod, but then I was worried that all of my photos would disappear. So I decided to update my iOS later so that I could transfer all my files on to my computer. I then unplugged my iPod, and tried to turn it on but the home screen wouldn't pop - no matter what I did, all the screen showed was an itunes icon on top with a USB plug-in cord at the bottom. So I had no choice but to restore my iPod. The thing is, once I restored my iPod and all, my photos were all gone and I did not use iCloud as a back-up since a few months ago. All of my recent photos are now gone and I have no idea how to recover them. I've tried programs that aim to recover deleted photos, but they didn't work.
Is there a way to recover photos after restoring the iPod Touch?

Hello,
It is very important to backup your device to the computer before updating or restoring.
You can restore your device to a previous backup, all the photos that were there when you made the backup should return with it, but I'm afraid that any photos taken or saved after the last backup are unrecoverable.
I hope this helps.

Is it possible to achieve 10 MHz output transfer rate on 6534 device?

I want to achieve 10 MHz output transfer rate on 6534 device. I need to contunuously generate non-repeating data. But when I execute the CVI sample program DOdoubleBufPatternGen653x, I cannot exceed the 1 MHz transfer rate (iPgTB = -3, iReqInt = 20), I get a -10843 error. Parameter oldDataStop is set to 1. Each halfbuffer contains 100000 points, buffer - 200000. My system is Pentium IV 2GHz, 512 MB RAM. What should I change to achieve 10 MHz transfer rate? Is it possible in this mode?

Greetings Alexey,
It should be possible, but it may take some extra thought and effort on your part due to the limitations and/or use case of your system. I would first recommend that you see the NI Tutorial "Maximizing the Performance of the NI 6534 Digital I/O Device" available online at . Based upon the error you are getting, it sound like you are not getting sufficient PCI bus bandwidth. Are you perhaps reading this data from disk (that would roughly double the PCI bus bandwidth required, or halve the transfer rate that you can expect to achieve) or using other PCI devices that are contending for bandwidth (potentially video cards, sound cards, network cards, dr
ive controllers...)? Some of these PCI devices need substantial bandwidth, others will grab the bus periodically for small transfers (sound cards, seemingly unused network cards forwarding broadcast packets...), and these could potentially interfere with your ability to stream data continuously at high rates. You might try disabling unused devices in your device manager. If you continue to have difficulties, please forward us more details about your system, what it is doing, and how your program works (are you streaming data from disk, network, or are you generating it on the fly).
Sincerely,
