PE1800 and PV110T LTO3 - ultra-lente performance

Hello world

I use the linux tar to back up data to a tape, LTO3 PowerVault 100t (several files about 5 GB each, every day a total of nearly 160 GB).
The problem is that the tape is slaughter starts every 5-6 seconds, I think that's what you call "Shiners", and the data rate is subject (please, no kidding!) only 2 MB/sec!

The source of data is a RAID 5 with 4 statement SCSI drives:
# hdparm-t/dev/sdb
/ dev/sdb:
Calendar of the disc in the buffer reads: 306 MB in 3.57 seconds = 85,61 MB / sec

The server is a PowerEdge 1800, dual Intel Xeon 3.0 GHz, 2 GB RAM

Operating system
Name: Linux
Version: Kernel 2.6.18 - 53.1.13.el5 (i686)

SLOT5-slot
Adapter: PERC 4/DC
Type: PCI X
Data Bus width: 64 Bits
Speed: [not obtained, see the documentation for the card]
Slot length: Long
Supply voltage: 3.3 v

BIOS information
Manufacturer: Dell Inc..
Version: A07
Release date: 29/09/2006

Someone at - it had the same problem? I've seen on this forum that others have this problem but they where using different controllers SCSI (Adaptec) and their operating system is Windows Server 2003.

Thank you all!

  • Qosmio X 300 and X 500-slow game performance

    Hello guys.

    I just got a new X 500 - 11 c less then a week ago. I've tried on wow and some of the new games like Bad Company 2 the two Online (on internet fiberPro 50/50). I must say that I'm really really disappointed. Both the X 500 and X 300 get so hot that I run both of the game at so low FPS I'm beginning to wonder if games really work.

    I have to say that both the X 300 and X 500 I tested with parameters "stright out of the box. But both have the same problem, they get hot, FPS drops and I pursuit get tired of running see ppl FPS jump from one end of my monitor to another because of the low FPS. Wow an SPF of 8-12 in a 5-25man raid.

    I have I have both tried to reinstall Windows 7 with system recovery and in both cases, it's the same thing, the com works fine until I have try and play a game. The surface under the monitor get so cabin that I can't hold my hand to her, and they all have two running so low FPS what it is no joy to play on them at all. I mean I can understand with some of the new games they can execute heavy but WoW is a game 5 year strand, the old system of gfx 32bits, I perform better on my old xxxx-mobile it is 5 years old and got a 256 in GfX card.

    Now, I tried to change the main HDD on a disc SSD of Pentecost and reinstall Windows 7 page home Toshiba + since the Toshiba training center to drive all the. That helped a little but not the STCUM.

    So I wonder, am I just out of luck I do something wrong or have I received 2 Toshiba laptops that have some bad material?

    I want to say that I have got this new because on the Toshibas home page, it says:
    x high-performance computer laptop, with all the latest features
    x multi-core processors allow you to do more at once
    x-recommended for extreme and multimedia games

    I hope that this extreme game of Pentecost they do not mean Tetris ore bubblebuble.

    My friend has a X 500 and it works fine.

    Your room is well ventilated?
    How long have you had the X 500? Maybe there is accumulation of dust in the radiator.
    Also make sure that the ventilation openings are not obstructed.

  • IOmegaEZ Media and backup center low transfer Performance files

    HI, I have a 1 TB storage media and Center IOmegaEZ backup.

    The operating system NAS device connected via the ethernet port to home LAN via a router device domestic classic.

  • vSphere and HP EVA 4400 storage performance

    Hi all

    Maybe someone can help me.

    Today I have a virtual infrastructure composed of two servers blades (2 cpus) and EVA 4400 storage with an enclosure full (12x400GB - 10krpm). Servers and storage are connected by fibre channel (4 GB connection).

    I was guided by the society that places the first architecture to store each VM in a single LUN in EVA. This means that my Active Directory VM with 30 GB of vdisk is stored in a 40 GB logic unit number. They said it was better for the performance of the virtual machine, because it will be "only" to the LUN. It's okay? Do I have to keep doing this or it is better to store as much VM as possible with a vdisk with max 256 GB (more small block)?

    I'm asking this because I'm planning and infrastructure upgrade: add another Blade Server, upgrade the 64 GB memory on each host and add another enclouser EVA storage (+ 12x400GB - 10krprm).

    Today, I have a considerable of I/O use because I run 5 noon productive SAP environments with Oracle database, a database of Oracle 11 g and several applications and infrastructure servers. With the upgrade, I might add, for storage, the following VM: swap (~ 600 mailboxes), SQL server, IIS, 2 x Oracle 11 g, print server, Nagios,...

    Please let me know your thoughts about the size of the LUNS to the virtual machines and the impacts on performance.

    Best regards

    Christian

    Hmmm... Another 'know everything' without actual knowledge consultants.

    If your multiple LUNS share the same physical disks - it absolutely doesn't matter in terms of performance if you VMs are placed on LUNS dedicated or shared. But you lose the flexibility with dedicated LUN.

    It's okay? Do I have to keep doing this or it is better to store as much VM as possible with a vdisk with max 256 GB (more small block)?

    Shared LUNS and several virtual machines on it will work absolutely perfect and you will be able to manage the space much more easily, especially with thin disks.

    In this case think of separate VMs with load I/O high and low load and place them on separate disk groups, so they definitely do not affect each other performance.

    Does anyone have this card and router are currently working? I bought them both, brand new in the box and it should be pretty much plug-and-play, but it's as if the router does not even recognize the card. I pulled the card, put in a laptop and the card works fine. The router works fine in itself, but it does not recognize the card either. Any ideas? Thanks in advance!

    I found the solution, so I wanted to let everyone know in case someone else runs into this. All I had to do was install the latest firmware for the router, and after that it was pretty much Plug and play. It works fine now. Thanks for the input so! B

  • Laptop HP OMEN - 15-J9K19UA: Omen Ops Central and performance HP monitor

    HP Performance Advisor is part of the Suite of the Ops Central HP OMEN; Since the last update (Performace Advisor. 1.8.7826.0), it is no longer present in the suite. Is there a procedure/process to add later in the Ops Central?

    Hi D5GR

    Thanks for the reply.

    Analyzer Performance HP automatically updated on execution and do not seem to have a setting to disable the upgrade.

    For this reason, restoration is not an option, it would just upgrade on the first run.

    Also, I don't see the problem here as being the performance Analyzer, but subsequently OMEN Ops Central. The configuration file now points to the wrong directory for the advisor.exe. Why the config is not editable by the end user? Or the continuation of the Ops Central needs a config file to reflect the new location.

    Center Ops Suite config

    LNK0018 = c: Program Files (x 86) \Hewlett-Packard\HP Performance Advisor\Advisor.exe

  • Satellite P200 - 1 K 9 and performance issue

    I hope IM this ad in the right area...

    Hello

    I have a Satellite P200 - 1 K 9 with the following specifications:

    Intel Core 2 Duo T7700 @ 2.40 GHz CPU
    3 GB RAM
    32 bit
    Note Windows experience 4.8

    ATI Mobility Radeon HD 2600 map graphic and one
    HD sound card...

    My problem is that since I bought my laptop about 7-8 months ago slowed down the performance. Of course, since then I had filled my hard drive (partition) with the media and understand that this is at the expense of the performance of the system. However, since this grateful I released a lot of disk space. I have 40 GB free on my C: and 90 GB free on my D:. Total, shared capacity is 250 GB (125/125).

    Basically, while being largely ignorant of the technical questions, laptops and technology altogether, the way I noticed the inability of systems to "return" to its original factory running (which, I might add, I was very impressed by) is when it comes to games. Football Manager 2009, for example running very slowly. I had a peek in the Task Manager, because I play the game in a window, and the CPU usage works 100%, although I'm sure the culmination of the individual tasks and Applications is not equivalent to that (maybe there is a program hidden Hogging my CPU speed?). Call of Duty 4, which took place on medium-high graphics settings when the laptop was new, now struggles on the lower graph and the sound settings, without that there is a problem with internet connectivity. In addition, (for reference, I m not not the game breath) Battlefield 2, which is about 3-4 years of age very slowly also works. He ran too extremely fast, on the highest graphics settings when the laptop was brand new.

    Basically, what I want to do, is to return the system to its original performance. It is always too slow when two hard drives were full of games and media. Now, despite the withdrawal of many of them, the system works like a sloth.

    Means I ve done to solve performance problems are: disk defrag, disk clean up, error checking, virus scan (with Kaspersky), scanning of spyware (with PC tools Spyware Doctor), deleted the old files with CCleaner and erased files not deleted with a program called eraser... As well as the release of about 50% of the disk space.

    Add to that, I ve noticed performance was much more when I first turn on the laptop and the sides of it n t had the chance to become hot. I understand what is normal, and he did before when the laptop was new and was operating at optimum performance, but perhaps I have an overheating problem? I'll let you know what is the temperature, but I put just t know.

    I hesitate to return the system to its factory settings and if necessary I'll take to a computer store, if there is something they can do. But in the meantime I d like to listen to any advice on general issues that I face, and possible solutions to my problem.

    Thank you very much.

    The problem with Windows is that it becomes slower and slower that you operate.

    When the devices and programs are installed, they increase the size of the registry, activate the Services, add resident DLLS and drivers, slow down the file system by adding thousands of files. As well, the operating system can get damaged after some time due to the loss of power and software poorly written.
    Even if you use CCleaner and other utilities and uninstall several programs, it is never as fast as a fresh installation of windows. Uninstalling programs rarely remove the program completely 100%.

    The antivirus can have a huge effect on performance, that's why the system runs great when the image of the plant is installed (which has usually no anti-virus).

    So basically if you want the system making a lot once again, you must back up your data and perform the recovery. I myself do it once a year to restore performance.

Maybe you are looking for
