• Usable disk HDS sizing question

  Hi guys,.

  I had a sales guys tell me:

  Rates based on 30% R10 / 80% R5-9.

  of course, you can not 30/80 so I assume he meant 30/70, which seems to the average

  I have trouble understanding how the usable figure below is happened?

  24 (23 usable) disc

  ARE OPS / s 93 794

• Satellite T130-hard disk/disk-Start Up question

  Hello

  I have a T130 2 years old that I use every day for work and have known no problem at all with him until a few days ago, when I noticed that it was taking longer than usual, to power.

  I checked all of my updates were up-to-date they are as far as I am aware of the Tempro and Windows. I did an AVG scan and nothing came out of the ordinary there and I'm still more than a third of the space on my hard drive.

  Everything was going well for a few days then yesterday when I tried to turn on the laptop wouldn't turn on at all--after several tries, on what he finally came and I kept it in sleep/stand by mode until I find what is happening. I ran the Diagnostic PC tool and everything is coming as a PASS except for the hard disk which appears in case of FAILURE. My USB pen is not registered when I try to use it. That said when I checked the PC Health Monitor, it says that my HARD drive was working and that my hard drive was 'good '.

  I assume from the above that there can only be one disk hard question - what is my next step? This kind of thing is easy to repair? Am I covered for what is a matter of product and less than five years, since I bought the laptop?

  Thanks for any help.

  Hello

  If the HARD drive is not present in the BIOS, you will need to replace the HARD drive with a new one.
  Do you know how to access the BIOS?
  Switch on and press the F2 key. Now, you should check the first page of the BIOS. Usually the CD/DVD drive and the HARD drive must be included with all the details.
  If the BIOS could not recognize the HARD drive, this means that the HARD drive is faulty.

  To my knowledge, you could use a simple 2.5 HDD.
  Here is a beautiful statement containing a few photos and film how to replace HDD on T130 series.

• Memory and disk HARD upgrade question - Satellite 5200 801

  Hi all

  I really need your help to upgrade my toshiba Satellite 5200 801 (model: PS520E-31P1D-EN), basically it's the version specification factory (technical instructions on the link below)
  http://www.cwrose.de/Toshiba/S5200.html

  What I want is to get faster internal memory, you can buy for this model (currently I have two default 256 mb DDR 266 MHz CL2.5 memory sticks). Will probably do a gig of memory (I could have more, but it depends on the price).
  As well, I want to spend the HD to 160 gig (about), as well as get a faster hard drive then the current 60gig 4200 RPM Hitachi HD (as soon as possible for the specifications of my laptop).

  Anyone know what would be the best option?

  Someone said that it would cost all under 100 (that would be cool), but I don't know anything about the compatibility of different companies etc.
  Can anyone recommend what equipment... .and where * I hope that ebay or studs :)
  I need to go to get this sorted out

  PS:
  FYI, I mostly use the laptop for graphic design, video, and the interwebz.

  Thanks for any help you can give!

  Hello

  You can upgrade the Satellite 5200 801 memory and HARD drive.
  S for laptop computer memory can be improved up to 1 GB of RAM. So you can use 2 x 512 MB PC2100 DDR - RAM modules.

  Check this link 5200-801 Satellite:
  http://www.orcalogic.co.UK/ASP/ProdType.asp?ProdType=6116&ft=m&St=3

  In my opinion, you can use the modules of memory from different manufacturers, but the module must support these specifications: 200-Pin PC2100 (266 MHz) DDR SODIMM
  I suppose you could also use a 400 Mhz because the laptop supports a 400 Mhz FSB too.

  I think that an upgrade of the IDE 160 GB HARD disk is not possible. To my knowledge, the BIOS can support such massive size of the HARD drive. But this is only my personal opinion. If I was you I would try a smaller HDD like 100 GB or 120 GB.

• Re: Satellite P200 - 1 K 8: used twice recovery - disk HARD size question

  Hello

  I was wondering if you could help with a little advice, I had to get my laptop p200 yesterday, it went well, but I noticed there was a 14 GB used in my hard drive, I know that vista is pretty big so I thought nothing of it, but due to an error of installation of some software, I had to get back again , this time I seem to be almost 24 GB used when there is no vista just the files on my computer. (I uninstalled all the software Toshiba because I don't use it either) any body have any ideas what it could be I know not on the score of 1.5 GB for the recovery, but I'm stuck as to where ive lost 10 GB

  Any ideas or help would be very appreciated

  Concerning

  Richard.

  Oh I forgot to add I can't with partition magic and I've added the files I have 7 GB now in program files and an installation of vista 14FR adds up not to anywhere near 36 GB, which is what is used on my hard drive

  On my laptop, setting it up like this:

  200 GB HARD DRIVE

  1.5 GB for Vista EISA (used to fix Vista) recovery partition
  6 GB for the recovery Partition Toshiba (used when you restore the HARD drive to its factory State)
  190 GB for Vista (its really about 178GB GB vs BillionByte of conversion and the Table of Allocation of files)

• Running out of disk space HARD - Question on the Windows folder size

  Hello! I am troubleshooting my HARD drive space. I have a 'C' HDD 16 GB with nearly 0 MB space left (fluctuates probably due to created restore points).

  In any case, I discovered that my Windows folder contains about 7.7 GB of files. (I have Win XP Home Ed, 2002, SP3 installed - with MANY updates that have been installed over the years) 7.7 GB seems a lot.  Random check on the web (not sure how reliable replica is) I see less than 2 GB is what should be there.

  I don't think that there are many 'other' stuff in there, certainly nothing that I placed there. is there a way to check / clean this folder?

  Please do not suggest to re - install Windows as the solution, since at that time, I will buy another computer first.  then put in shape this one. It is clocked at 2.66 GHz Intel Pentium, so not ready to junk food she still.

  Thanks for your suggestions. Best regards, Frank V

  Your list of the most fragmented files that partially reveals the magnitude of your problem. Note that the list does not display very large files that have less than 797 fragments. There are also many small and medium-sizes of the files fragmented with less than 797 fragments. A notable omission in your list, this is the System Volume Information folder. I can't believe that it is not fragmented, she must be on this part of the list is not displayed.

  To defragment by using with Windows XP Disk Defragmenter, you need a bit less 15%. Defraggler is my favorite Defragmenter, but I doubt that it will succeed on your C partition. With Defraggler you can defragment single files, except some files, including those related to safety programs. You must try to reach 20% of free disk space.

  Your swap file is severely fragmented and illustrated perfectly why the possibility of using the "let Windows manage" is not the best solution if you want the better system performance. Minimum setting fixed maximum = pagefile avoids what you see on your system. Unfortunately with a populated partition, it is very difficult if not impossible to resolve completely without having to reinstall the operating system. However, trying to mitigate the impact of what you see, it's something to watch much later in the restoration, the functioning of your computer.

  My previous to Outlook Express references were specifically directed against this program. Outlook is a totally different program and solutions for Outlook Express do not apply to Outlook.

  You cannot compact Outlook pst files and archives, except those who created versions of Outlook prior to Outlook 2003. You can empty deleted item folder and you must first check that it is empty. I would then back up your Outlook Archives on an external drive or flash before attempting to move the locations of archive. Once you have moved the archive folders successfully I would then move messages from your current folders to the archive folders. If you archive the current materials first of all you have more to lose if the process of change the default location of the folder goes awry. Then, you can archive your current messages and change the default location of the current file. You can move messages current return from archives as a last step if you feel the need to do so.

  I copied a few instructions from an external source on how to change the default locations. I hope you find these useful.

  To change the location of database of Microsoft Outlook, the OUTLOOK file. PST is to be moved. In Windows XP, you can find this file in the folder C:\Documents and Settings\loginname\Local Settings\Application application\Microsoft\Outlook\ and in Windows Vista, you can find it in the C:\Users\loginname\AppData\Local\Microsoft\Outlook\ folder. After Outlook is closed, the OUTLOOK folder. PST can be moved easily using Windows Explorer by cutting (CTRL-X) and paste (CTRL-V) in the personal folder on the partition data (for example D:\loginname\Outlook). Now, the file is deleted from the original location, Outlook will present an error message because the database can not found. Accept the error message, navigate to the new location of the OUTLOOK. PST file and restart Outlook.

  ATTENTION: If automatic archiving is enabled, the ARCHIVE file. PST must be moved as well! This file can be moved to the same location as OUTLOOK. PST, following the same procedure.

• Consolidation of Virtual Machine disk is necessary question

  Today, I have one of my virtual downwards because the error message that says that "there is no more space for disk virtual xxxxx - 000018.vmdk.» you might be able to continue this session by freeing up disk space on the relevant volume by clicking on try again"

  I want to know why this happened if I make my virtual with 1.5 to and my server is new... so for the most part the server have 300 GB in use... I also had 750 GB available for an another virtual and that the question, why this virtual grow too much and too quickly?

  Also when this happened how can I do to solve this problem, how disk space if I did a single data store with al the available space.

  The suggestions will be welcome.

  Thanks for you comments.

  Concerning

  JP

  In the files you posted, it appears that 000002 and 000007 files are not in use by the virtual machine, but the others are. What I recommend you do is to open the Snapshot Manager, create a new snapshot and then run "Delete All". This should clean all the snapshots except for the two mentioned above. If this is the case, shut down the virtual computer and move the two snapshots listed in a subfolder (to be able to restore them in case I'm wrong), then power on the virtual machine again. If there is no error, you can delete the moved files.

  Unfortunately I can't see any rule, snapshots are used and that have been created just for adding hot backup not, so you should always have to understand this from scratch. At least for the moment until Acronis comes up with a fix, you need to delete snapshots manually on a daily basis since the Snapshot Manager (create a new cliché-> Delete All) to avoid any trouble with too many active snapshot on the virtual computer.

  You have another virtual computer that has NOT "changed block Tracking" on, to see if the problem is related to the CBT!

• Virtual disk / cliché Consolidation Questions

  Hi all

  Guidelines in the Article of the basis of knowledge 1007849 (link), I have a few questions about the Consolidation of VMDK/Snapshot.

  First of all, there is no. SNAPSHOTS (or SS files) in the Snapshot Manager or browser (However, I believe that it is because I am committed never completely the prior of snapshots).

  As can be seen in the picture, I have 3 flat files:

  File1.VMDK (10 GB)

  FILE1_1.VMDK (35 GB)

  FILE1_2.VMDK (60 GB)

  Run the commands (and in the browser), I show that I have 4 files with extensions: vm_x - 00000 x hard-x (where x = 1 or 2) with three original flat files.

  As can be seen in the picture, they are:

  File1 - 000001.vmdk (1.4 GB)

  FILE1_1 - 000001.vmdk (7 GB)

  FILE1_2 - 000001.vmdk (28 GB)

  FILE1_2 - 000002.vmdk (132 MB)

  The commands show the files in use are: file1 - 000001.vmdk, FILE1_1 - 000001.vmdk, FILE1_2 - 000002.vmdk

  My goal is now to consolidate these four files of x - 00000 x hard with the original flat files (I'm running out of space on my LUN and badly need to reclaim the space used by deltas).

  The rest of the Article, I can do that by cloning the LAST delta file (vm_x-x - 00000 x hard) to a temporary logical unit number and the result will be a FLAT file with all the changes of delta AND the original structure. I can then do this for every disc of delta and the result would be 3 dish VMDK, thick well consolidated with changes in delta and the original content to the size of my original housing.

  Am I wrong? Or am I missing something?

  Any advice/help/advice/suggestions on VMDK/Snapshot Consolidation would be greatly appreciated!

  Tony

  Tony in the morning,

  I agree / 3GB is severed a small fine.

  The two should get the same result, but I guess the question should be asked and answered is: are you able to shut down the VM? If the answer is Yes, then or the other option is fine, but I'd probably go with the vmkfstools-i option first. If the requirement is to leave the machine on then I would use the VMware Converter to achieve given the free space you have.

  I just had another idea. If you use vCenter, then you can also clone the virtual machine. It would be almost identical using the vmkfstools-i option. Make a clone should be faster to copy them what VMware Converter like all across the disks rather than go on the network. There are the assumptions in this howerver statement generally it should be true. The only problem with it in this way is the hull of the virtual machine will need another name, while the vmkfstools option you can just do handed up new discs of the same shell. Depends on how comfortable you are with the console.

  .

  Let us know how you go.

  Kind regards

• Oracle RAC 11 g 2 on Windows - disk storage Newbie question

  Hi all
  
  I read in the network installation guide in order to understand how to set up a RAC solution. I am new to Oracle for many of these concepts, I am trying to understand, but what I read a typical installation would be to have my cluster software installed on a particular type of shared storage of OCFS or ASM. These types of storage can sit on top of a redundant option such as RAID or logical volumes on disks or some sort of mirroring (same THING).
  
  I know what I said is probably a rough attempt to understand it, but what I would like is if anyone has diagrams that lay this out for me using my understanding it would be great.
  
  I'm a bit at a stage where I think about creating a RAC on some VMWare installation and want to know how best to configure the drives initials and to add to a RAID or burn on partitions.
  
  Hope I made sense.
  
  Thank you

  You can find several scenarios on this pages:

  You can use 2 different articles - one for windows OS setting, second for DB.

• Acceptable DELL PS4100xv and SAN HQ disk performance

  Hello

  I have a Dell PS4100xv with 12 x 600 GB 15K SAS drives configured in RAID 6.

  3 three R420 servers are connected via 2 x Power Connect 6224 (bunk).

  I'm under ESXi 5.1 U1 with a mixture of SQL virtual computers, file servers, and Proxy servers.

  What are the acceptable values for a healthy EQL in terms of latency, disk queue, Ops ARE / s and etc?

  Just recently, I transferred a virtual machine to the PS4100XV. The virtual machine has a very slow behavior when using the EQL Dell. This is SQL Server. You have a lot of users complaining about the sluggish behavior.

  I need to determine if I have a problem on my PS4100xv in terms of performance before you start to troubleshoot the VMs and ESXi hosts.

  These are values measured HQ SAN during the last eight hours.

  If I got this right that my own analysis

  • The disk queue is ok, since its constantly @ 0. EQL can handle the load and nothing is pending.

  • IOPS / s is ok, because the base on the RAID my table evaluator should support 1500 IOPs. Current reading is 742 IOPS / s only.

  • To write latency is ok because he is 13 Ms and does not even approach 20 ms.

  • Latency of reading, I have a problem? It fits above 20 Ms flat around 25 ms to 40 ms.      But not more than is not 40 ms.
  • For the size of the IO rate & IO, I don't know if that's a good indicator. What are the acceptable values?

  Disk queue depth:	zero (0), the graph shows his dish to zero.
  Average READ IOPS:	625
  Average WRITE IOPS / s:	117
  Total average IOPS / s	742
  Latency average reading	30 ms (ms 20 to 40 ms)
  Average latency of writing	13 ms (straight line @ 13 ms)
  Weighted average	28 ms
  E/s average rate readings	26.41 MB/sec
  Writing of average IO	2.26 Mbps
  Total	28.67 MB/s
  Average size of READ i/o	43,30 KB
  Average size of i/o WRITE	19.91 KB
  Weighted average	39.62 KB

  There is no retransmission of packets and the network usage is only 3%.

  Would really appreciate the input and recommendations.

  What are the acceptable values for a healthy EQL in terms of latency and IOPS / s, queue disk, etc.?

  Thank you

  Paul

  I strongly suggest you open a record of support on any show of related issues.  However, with ESXi especially when I see low i/o + latency, the first thing I usually find is that DelayedACK is enabled.  Sometimes, large receive the unloading (LRO) can do that as well.   Another common problem is not optimize MPIO.  And not not not using Round Robin with 3 IOs by path from the default value of 1000 IOs.  Or if you have a company or business license + installation Dell EQL MEM.   Sharing also several VMDK with one card virtual SCSI inside each virtual machine is another cause of latency.   Each virtual machine can have up to four 4 virtual SCSI adapters.  With a single adapter, single VMDK (disc) can be active at a given time.  If an operation of e/s on the "C:" drive will block your SQL disks.

  This link is a PDF that will show you how to fix common incorrect configurations with ESXi + EQL.

  en.Community.Dell.com/.../20434601.aspx

  HOWEVER.  If you find delayed ACK is enabled the process described here probably won't be enough to solve the current connections.   With the mode node maint.  Remove the address of discovery EQL, remove the "Static discovery" entries EQL volumes.   Restart the node.   Add discovery addresses but NOT yet rescan.  Make sure that login_timeout is 60 years old, DelayedACK is disabled.   Then make the new analysis.

  Kind regards

• Unable to restore the system, possible hard disk problems

  I started to have a white screen on startup and could not go beyond the apple logo. I ran the recommended repairs but could not manage to detect the operating system if the recovery console could see everything fine. The console suggested a repair disk I ran, but it seems to fail and goes to a blank gray screen.

  I pulled the drive and back up the contents of my PC and noticed them were three partitions showing in this regard. There was no problem of backup files as well so it seems that the drive is ok. After plugging it back in I tried internet recovery option and it only detects the HD recovery. I tried to erase disk02 but it does not work as well. I also use the restore option, but this also fails. I'm more used to the windows system restore and I'm not sure just what I might be missing.

  I have attached the photos on what I see, so hopefully that will help.

  http://imgur.com/a/nsyx8

  Enter the Recovery > disk utility. Select 1 TB HD Apple ST *, and then click Delete. Then click the Partition tab use arrow on the "Current" bar and select 1 Partition. Below you see a + sign or Options and will make this is the Table of Partition GUID. You will be he title Macintosh HD and Mac OS extended (journaled) and then click on apply. Now, you'll see Macintosh HD instead of the disk 0 sec 2. Select Macintosh HD, and then click Delete. Now, you erase Macintosh HD. It should be GUID Partition Table Mac OS extended (journaled). You should be able to put it in to your Mac you install El Capitan. Hope this helps you.

• Average read get-stat - virtualdisk.read.average stat?

  Hi all

  I want to use the metric virtualdisk.read.average to calculate the average read speeds per virtual disk to a virtual computer in the last 24 hours (using the 5 min interval)

  [1]

  I want to calculate the average in * every * instance and then add these individual averages until you get the desired amount.

  For example (using real-time output just for example only, I want 24 hours actually):

  MetricId unit Insta timestamp value
  NCE
  --------                ---------                          ----- ----     -----
  VirtualDisk.Read.Ave... 13/05/2011 19:39 6 Kbps scsi0:0

  VirtualDisk.Read.Ave... 13/05/2011 19:38 431 Kbps scsi0:0
  VirtualDisk.Read.Ave... 13/05/2011 19:39 10 Kbps scsi0:1
  VirtualDisk.Read.Ave... 13/05/2011 19:38:40 Kbps 0 scsi0:1

  VirtualDisk.Read.Ave... 13/05/2011 19:38 0 Kbps scsi0:1

  Average (6 + 11 + 39 + 431) = 121.75

  average (10 + 0 + 5 + 0) = 3.75

  Total liked: 121.75 + 3.75 = 125,5

  What is the best way to achieve this? (Unfortunately there is no global instance as with the network and cpu.usagemhz parameters)

  [2]

  For the calculation of the IOPS / s, if you use the metric datastore.*, OR as the virtualdisk.*, is the following statement, 100% good:

  (a) virtualDisk.number [Read |] Write] Averaged.Average will calculate the OPS are / s generated by the virtual machine

  (b) disk.number [Read |] Write] .summation will calculate the OPS are / s that hit this particular data store (useful to see how busy is a data store - but will not provide any info on a single virtual machine (unless by chance, there is only a virtual computer on this data store special))

  [3]

  How to use virtualDisk.number [Read |] Write] calculate the IOPS / s for a given virtual machine?  Depending on the issue [1], to each VMDK, PAHO are / s on average individually and then add the averages for overall IOPS generated by this virtual machine in the last 24 hours?

  [1] use the Group-Object and Measure-Object cmdlets for this.

  For example

  $vm = Get-VM MyVM $report = @()
  $stats = Get-Stat -Entity $vm -Stat virtualdisk.read.average -Start (Get-Date).AddHours(-12)
  $stats | Group-Object -Property Instance | %{
      $row = "" | Select Instance,Average
      $row.Instance = $_.Group[0].Instance
      $row.Average = ($stats | Measure-Object -Property Value -Average).Average
      $report += $row}
  $report $total = ($report | Measure-Object -Property Average -Sum).Sum
  Write-Host $vm.Name $total
  

  This will calculate the averages per virtual disk and add the averages together

  [2] see my post get PAHO are / s maximum .

  (a) Yes, provided that you add the OPS are / s for each virtual disk total

  (b) No, if you run the Get-Stat for an entity that is a virtual machine, you will get the statistics for this specific VM disk.

  The metric is available for HostSystem and VirtualMachine. See the column of the entity in the drive settings page.

  [3] Yes

• Satellite A50 - recovery disk is not working

  Hello

  I'm trying to do a clean install on my laptop, but the recovery disk is not working.
  The files transferred to the laptop, but once done, I get an error message that says: "the system is not fully installed. Please run Setup again."

  Does anyone have suggestions as to how to fix it?

  It took me four days to get to this point and make me very frustrated.

  Thanks heaps

  Hello

  What is the installation using another CD; That is to say the Microsoft Windows XP disk?
  Have you tried that?

  In my opinion, this would help to pinpoint the problem
  The error message can be linked to different issues; I mean the HARD drive or a single partition problem could also be possible.

  Try to format the drive HARD whole again. Delete all partitions from the HARD drive and check if you can proceed with the installation.

  But if you will not be able to install the OS by using the recovery disk and other disks then a question must relate to a part of the material. (possibly HDD)

• Re: Recovery disk is not recognized

  Good evening.

  I have difficulties to re - install my Win7 on a Satellite L555 laptop.
  Last week I cought a virus "system check", which could be removed by anti virus software and a trojan remover. But to make sure that the infection is without any residue I would format the HARD drive and reinstall Win7.

  Having an original Toshiba-restore disc I hoped for an easy installation, but or modify the BIOS settings (despite the changed settings that it started normally via HARD drive instead of recovery disc), or a Windows database recovery proved to be fruitful. In the latter case, I was told no valid Windows installation disc would have been considered - despite the recovery disc and it try again several times. Drive and disc are fine, I coul access it through Windows.

  What can I do now? Why Windows do not have the original recovery disk?

  Additional information: I got the HARD drive changed a few weeks ago, the newcomer in the mail and I could easily install Win7 on it - this very recovery CD which is now referred to as "invalid"...

  Kind regards

  > Why Windows do not have the original recovery disk?
  This question confuses me in the history. Why Windows should accept recovery disk?

  Start your laptop and press F12 repeatedly. You will enter the boot menu. Place the recovery disc into the optical disc drive. In the menu choose the CD/DVD drive and press ENTER.

  What happens when you do this?
