• RAID and ESXI 6

  I have an R410 with a Perc S300, 500 GB HD 7.2 K Sata HDs w / 16 GB of RAM - I'm looking to install ESXI 6 and failed due to unsupported S300.  Can you provide recommendations on a Perc replacement that will work with and run 6 ESXI.  Also recommended Perc supports SAS and SATA if we decided to upgrade the drives.

  I saw Perc 6 / i and HD200 but do not know who would be a good replacement for the S300.

  Thank you

  The H700 is really the only controller you should consider. On PERC 6 would be nice, but it is 1) a 3Gbps controller and 2) is limited to the physical drives of 2 TB. The H700 has none of these restrictions.

• Openfiler as NAS for ESXi shows the performance difference between software RAID6 and RAID10.

  I had some performance issues with a new ESXi server with virtual machines hosted on a table of 6 software RAID (12 units of optical fiber). Here's what it looked like:

  12 multi-plate (RAID 6) -fiber channel- Openfiler.

  ---

  NFS - VMWare ESXi

  Since I had a spare CF array I decided to fix to the Openfiler box and try to RAID 10 in software. Different performances has been staggering. I did a lot of steps, but I test the startup time of a computer virtual stored on each table of FreeBSD.

  RAID 6 59 seconds

  RAID 10 45 seconds

  Now waiting for MBR of FreeBSD for 5 seconds and the boot loader expects 10, so there were at least 15 seconds of downtime in each case. The strange thing is that accessing directly the matrix RAID 6 via FTP provided good performance. I was able to saturate a 100Mbit link and the Openfiler Server showed almost no load. But with the VM on the RAID 6 array, the load on the Openfiler area would jump to 4 +. I hope it helps someone.

• Need help with the disks 'unreadable' configuring software raid after the death of the startup disk and system restored.

  I'm looking for some advice on how to restore a windows xp installation software raid 5 that was running on my XP system. I had a problem when the startup disk has failed, but I was able to backup the system before it can. I replaced the drive and restored the system and everything came, but I was not smart to do this and accidently left the readers connected when restoring raid. I don't know if windows has done something when I tried to install XP on the new drive, or maybe something else has happened when I restored the system from the backup, but my raid drives can not be used. There was a moment in the restaurant business I saw a message on the MBR, but I thought that was just for the drive being restored. I didn't have a single player who held any information on the other disks in the system, but I'm not 100% sure on that.

  When the system boots the windows logo screen takes 10-20 minutes before you get on the desktop. Windows Disk Manager takes 20-30 minutes to fill the list of drives and status on the disks three raid is 'dynamic' and 'unreadable' is not reassuring. I suspect it's a problem MBR or partition table that must be corrected before trying to reactive the raid, but this is just speculation.

  The raid drives are on a promise ide/scsi disk and make it appear to start correctly with names and sizes. After that I get nothing. I do not have another scsi controller (or), but I thought I'd try active @ partition recovery to see if she can find information on the disks.

  I hope someone has some experience with recovery like this, because this is a first for me. I thought I was pretty sure running a raid-5, but wouldn't you know, the tech gods have found a way to crush my plans...

  Thanks in advance for any help!

• RAID 1 hardware and ESXi - host not to see the virtual volume

  Please bear with me as I try to explain this issue in detail.

  I have an ESXi server.  He has a number of virtual machines and works.  This server has a LSI RAID controller and had a single hard drive connected to this controller.  I'm allergic to non redundant drives, so I added a second drive and, from BIOS boot from the RAID controller (before initialization of the server itself), I created the mirror and had the controller 'rebuild' the second disc, copy of an image of the first record on.  The controller did and displays a virtual (in BIOS) volume in a RAID 1 volume consisting of two physical disks.

  At this point, I expect from any server OS to see the single volume.  However, ESXi, at startup, see both drives hard physical (apparently without taking into account the supposed configuration of the controller, which is strange for me), and because they contain all the two identical copies of the ESXi installation, it purple-screens to complain about two identical UUID.  When I work around this error with the start command line option 'overrideDuplicateImageDetection', ESXi starts on one of the two disks.  vSphere shows the two disks and physical disks, mounted in the system.

  I'm relatively certain that the RAID card maintains the mirror.  The second disc is not part of a data store.  I would prefer ESXi see the mirror as the only logical volume so-called offer the RAID card, but I'll settle for ESXi, ignoring the second unit of disk in total.

  Any ideas?

  Thanks in advance for your help,

  Hello

  Some RAID controllers operating in RAID or RAID configuration. If no RAID is created, it will work like the generic SCSI cards and when a RAID is created then it will become an appropriate raid controllers. When you installed the ESXi map was probably operating in non RAID and later converted to a RAID controller mode. Please check the drivers loaded in the kernel of ESXi and if necessary, please include the RAID controller module and re build the boot image.

  Is it possible to give me the model number of the LSI RAID you use and the output of the inscription of the kernel module. I think that these dual-mode controllers were possible on older models of server, not sure that they are always available. I used to see this kind of problems with Linux in ancient times.

• RAIDs of ESXi

  So I'm at a bit of a delema. I want a high availability system (err, around)...

  Currently we have a machine, I can get a second, but we cannot drop 2 k $ on vCenter to give living vmachine transfers when they die (true high availability).

  What I wanted to do was run a RAID, I'm uncertain on material RAIDs being as if material goes wrong, I need to go hunt down a similar card or the data on the disks are useless. Software RAID is great, but is available at the level of the VM, which means that if the OS drive dies, ESXi will start is no longer. And I can only handle the RAIDs started when equipment fires upward.

  I was going to set up our virtual servers with virtual RAIDS on 2 discs so they could get the extra security of the speed and the data, but is not this backup of almost just as good as the virtual machine every night (less lose a few hours of work), this in fact also a bet of 50% that it is either the OS of the 2nd drive disk in the RAID.

  Anyway, being as I'm new, what are my options to maintain a profitable facility for a small office with backup simple and fast restoration after a catastrophic failure time?

  Going to be an older Poweredge 1435SC with the installation of 120 GB (main) and the 1 TB drive (storage). I have the additional external backup storage.

  Not having not not 100% uptime is fine, but I'm wishing to reduce downtime and complexity as much as possible when the operating system drive fails and if RAIDing at the virtual machine level isn't worth the time. Should I keep just readers VM backups that are important? (we've got some that are volitle, and I have no 1.1 TB of backup storage, so I need to choose what to keep and what to chuck) and keep them all a single hard drive on the level of the BONE, and when things die I just reinstall ESXi and restore the virtual machines?

  Only VMWare has some backup software that I can connect to ESXi and basically their migration to a backup disk every night?

  Should I throw them to the tops of my arms and say "It will be fine!" and run with a hardware RAID? Am I too worried about hardware failure? Hardware RAIDs become more standard in how they are setup so that I can transfer to another machine easily?

  I would have to turn off the machine to swap anyway, readers being what they do not have hot swappable bays. > >

  Yes, you are being far too dramatic on the material.  Hardware RAID is your BEST high hand option.  Disk fails, using RAID 5 you can have 1 disk fails, and data are preserved, no interruption of service.  RAID 6, you can do it with 2 discs.  Fundamental difference is the performance, but I've not seen much of a difference, if any, performance.  so if you are paranoid to go with RAID 6.

  SE RAID won't save your VM, it will only mean that you can continue to operate in the event of hardware failure, your VM is still subject to corruption, the user misconfigration and deletion of data within the VM OS, this RAID is only part of the picture.

  If you are unable to remove $2K on VC, then you will not be able to buy backup either.  All backup solutions cost something and depending on how many you have, it could cost a lot.  Now you can use esXpress if you weren't on ESXi... esXpress does not work on ESXi, but it runs on the console version.

  So, I say make a case for VC and make someone responsible for purchase VC, you need.  You see already the advantage... then fight for it.  It's less $ 150.00 per month (if you do this for the 2010 budget)... but the return on investment is HUGE in less time.  So for you VC will save you problems hardware and the management of the virtual computer.  Of course that vmotion is assuming that you have the Central SAN solution.

• Satellite U940 PSU6VA - recover after removing the software RAID

  * My specifications: *.
  * Model: * Toshiba Ultrabook (Satellite PSU6VA - 00S 002 U940)
  * Operating system: * Windows 8.1 x 64 (upgrade of Windows 8 x 64)
  * Storage: * 500 GB + SSD 30 GB HARD drive

  This particular model of Toshiba comes with two hard drives (a HARD drive and SSD) and uses the SSD for caching purposes. I think to disable this caching so that I can use the SSD for other purposes.

  However, according to the observations of MannerhagenVPO in [this thread | http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=79976]:
  -This caching is implemented with a software RAID
  -To access the SSD, you must remove the RAID software
  -Once deleted, software RAID can be restored by an authorized Service Professional. Even the Toshiba recovery media will not be able to restore it.

  I'm not really worried about permanently losing the caching features. What concerns me is this: the Toshiba recovery media will always be able to restore Windows 8 (but without caching)? Or the recovery media Toshiba will become completely useless if software RAID is deleted?

  As far as I know the RAID features will be removed if replace you / remove or change the SSD or HARD disk drive.

  In any case, using recovery media created by Toshiba Recovery media creator software you should be able to reinstall the Toshiba preinstalled system

• DiskPart / software RAID - disaster recovery

  Hi guys,.

  I have a VMware VM running Windows 2012 R2 DataCenter Edition. I tried to clone a DR test for one of my clients. I was able to start the virtual machine in Recovery Mode and use diskpart to assign the appropriate drive letters, etc. (it is a software RAID 1 mirror) after importation of disks (they appear as foreign at first) and the output.

  I have tried a number of tools - however, when system - bottom line - restarts looks disks back to being at reboot - what makes the system unable to boot properly.

  Any ideas on how I can get the data from partition table that I put in diskpart persist beyond a reboot?

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• Software RAID for Server 2008

  I have a PC that I want to load Server 2008, with two sets of HDD of 250 GB in RAID 1. My motherboard doesn't support RAID 1, can I find a software RAID that will work with Server 2008?

  What I found which seems to have worked. I installed the two 250 GB HARD drive. Then the loading of Windows Server 2008 R2 SP1, when he asked which will lead to load on, I chose the disk 0. After completing the installation of Windows, I went to disk management. I saw a disk 0 by a system reserved 100 MB, a C: drive with 232,79 GB type base and a GB 1, unallocated, 232,88.

  I have converted the disk 0 to dynamic. Right-click Disk 0, select Convert to dynamic disk.

  Then I have a right on the C: drive and selected click Add Mirror, selected disk 1, ok/next, then it C: mirrored on both drives. He left 100MB on disk 1 unallocated.

• What type of Raid and disk offline

  Hello world

  Thanks for reading this.

  I have a Dell Poweredge T6300 with a Perc H730.

  It has 8 drives 1 TB 7.2 k.

  It has a C drive and a D drive.

  Looking at the Server Manager / file C and D Storage Services seem to be Raids but I'm not sure what kind.  One of the disks in the set of 4 seems to be flashing orange offline.

  Server seems to work very well.

  Seems that I can't find a way to check the type of Raid without stopping and running Perc H730 map (CTRL + R) software.

  Is this true?
  I think I can hot swap according to the Type of Raid, and I believe that the hardware supports that.

  I was wondering if I think in the right direction.

  Thanks in advance.

  Hi DLOJ333,

  Did you mean you have a T630 instead of T6300 model?

  You can install Open Manage Server Administrator, who will monitor your condition storage and server real-time hardware. Just make sure that you check to install Storage Administrator. This may require a reboot of the server for the registry and the service is running.

  Additionally, make sure that you are running Windows Server.

• Software Raid key for 2 hard drives

  -Does anyone know if a key of software raid is required for a raid HDD 2 1 or 0, in an on-board raid controller?

  Yes you have reason, what I meant is that by default the (onboard) raid software can supports raid 0,1 and 10, but you must meet the requirements of the hard drive.  For the c220 Server m3 you have not needed a key for raid 0 or raid 1, but you must make sure you are using SATA drives, if you use SAS disks, then you need the key.

  In this link, you will see the driver you need (according to your hardware/software/firmware). We just started to include a file .iso from the driver that tells you what version you will find in the file itself. Unfortunately, before the latest driver .iso we had only so you'll have to download them and whether the version you need is included there.
