• Software RAID and ESXi

  I was intending to set up a CentOS 7 seveal VMs server and a file server. I was planning on setting up with BtrFs in software RAID 10. However, my company is looking get ESXi and wants me to get some experience with it so I'm considering now to configure the server with ESXi and all my virtual machines running on that. What I was wondering is how I can use software RAID to save what will be my main VM, install a CentOS. Will be setting up software RAID using BtrFS on the virtual machine is useless? If the drive containing the ESXi installation failed, I completely lose it?

  Could I do something like install ESXi on a server on two SSDs running RAID 1, then install at least one of my virtual machines to use RAID 10 on hard drives or not because all this abstract?

  Welcome to the community,

  ESXi does not support software RAID, but only "real" hardware RAID. With hardware RAID, you can set different logical volumes on different disc types, create warehouses of VMFS data on them and then decide on a per-VM basis where to store the virtual disks. You can even have several virtual disks per virtual machine and store each on a different data store.

  You said install ESXi on SSD. Once started, ESXi runs in memory and can even be stored/started from an SD card or a USB device. There is no need to spend money for the SSD only install ESXi.

• 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.

• storage and esxi 4.1 configuration

  I'm new to esxi 4.1 and have done research on configurations. The will of VMs, I'm looking at hosting a Server 2008 SBS (Exchange), 2 Windows 2008 servers. We are looking at a Dell Poweredge T710 with 16 GB of RAM, dual Xeon E5645 procs and 6 1 TB 7.2 k drives in a raid 10 configuration.

  The SBS and one of the 2008 servers are just for Exchange and some local databases. Server 2008 remaining is for a scanning solution and will most of the storage.

  What I read in the forums, I have some questions:

  1. 1 TB disks will be good enough (much?) performance wise or should we invest more in the faster discs?

  2. If I create the virtual machine and want to share storage should I create another virtual machine and install openfiler to manage the remaining disk space? Or could I use a raw connection of a store of data to one of the servers 2008 and share him?

  3.I also realize that esxi has a limit of 2 TB data store. Does that mean I can create 2 partitions during the RAID and have 1 to 1 and the other 2 to?

  You can thin available to a player. Add a large thin drive and it will increase in size when you add files. You can also keep addig additional 100 GB disks or you can easily develop a reader if necessary.

  I would just like to add disk space that you need. Use Windows to share flies, rather than adding complexity to your environment.

• Adding a new drive of 1 TB Adaptec2610SA and esxi 3.5.0

  Hello

  It's really confusing to me.

  I have a system that works for 2 years now.

  I have 2 drives raided and work in my esx 3.5.0 on my HP Proliant ML115 G5 server. I has been working perfectly without any problems.

  I wanted to add a few more storage so I boughty myself a whole new drive 1 TB and set everything off and put it in.

  Went up in the utility RAID at startup and makes sure that I could see, but not a not joining the existing raid array as I just wanted to use as 1 additional storage room.

  Anyway to cut a long story short, - punt in esxi, has launched the customer infrastructure and went to the storage adapter expecting to see here. NO.

  Therefore a new analysis and NOTHING.

  Put and old 40 GB drive to and bingo she appeared right. (this player may have been formatted, but that's the only difference I could think off the power)

  The new Terabyte disk in and nothing new.

  Any ideas.

  Y at - it sort of command line hardcore scan I can do to force his apperarance.

  Thank you.

  Did you create a new table with the single disk. The controller do not know, but I think that you must have a table before being transmitted.

• RAID of ESXi 4

  I recently bought a Tyan very 2927-E motherboard and have discovered that the RAID on Board (Nvidia MCP55) is not supported as a RAID for ESXi 4.0 solution. What is a good solution for a map of RAID controller to host two to four 300 GB HARD drive at a reasonable price?

• 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.

• R610 Perc 6 / i Can I have matrix Raid and independent labels?

  My R610 with a Perc 6 / I can take 6 physical disks.  I want to create a raid 1 with the first two discs, then install 3 drive more that BONES can see and use in a storage space.  However, I can't figure out how.

  I have my setting up a raid and windows installed and I have the other 3 drives inserted, but Windows does not see them.  Maybe that's not possible, but I wanted to ask if anyone else had any ideas on how to make this work.

  Thank you.

  PERC 6 is not compatible no RAID, so if you want to use these disks separately, you must configure each as a single drive RAID 0.

• Break the RAID and the displacement of the OS to a new hard drive

  Hello

  I have a MSI GT683r laptop that is configured with two 500 GB Hdd that are configured in RAID 0. I wanted to disable Raid so I could separate my windows OS of my alternative OS on two different hard drives. Im a student, so I have lots of important programs and documents on my PC right now and I was wondering how can I mirror/clone/transfer my exisitng OS (as part of the RAID 0 stripe) and move it to a single hard drive. There are some caveats to this and how to go to that topic.
  Thank you very much in advance

  RAID 0 distributes all your files on both drives. Break the RAID and you have data or programs, not even a bootable OS. So you have to backup your data before breaking the RAID.

  To preserve your current operating system and transfer it to one of your readers courses will require using a 3rd hard drive to clone the current operating system from before the breakup of the RAID, so that it can then be cloned to one of the original disks.

  It will not be possible if you store more data on RAID 0, that can be accommodated on a single disc. With your drives, if your current RAID 0 (maximum 1 to) has more than 500 GB stored, this cannot settle on one of your hard drives of 500 GB.

• Update for vsphere client and ESXi host, now getting errors

  Did a upgrade for my client vsphere, VMware-viclient-all - 6.0.0 - 3016447.exe file name

  Now I cannot view comments consoles, cannot add new guest OS (option is grayed out), and I get an error when the Client program starts (see first image)

  

  Here is the error when I try to view the console to the guest operating system. Can I use Remote Desktop connection to connect to the guest operating system (R2 for Windows Server 2012)

  

  Here is the version information

  

  Also improved the host system of the ESXi server to update to U1 using the VMware-VMvisor-Installer - 6.0.0.update01 - 3029758.x86_64.iso

  VMWare Tools never seems to complete the installation for the guest operating system.

  What can I do now?

  Client runs on a desktop computer Windows 7 Pro with 24 GB of RAM.

  ESXi is a server Dell Poweredge T110-2 with 32 GB of RAM

  I ran into the same issue and Re: VMware-viclient-all - 6.0.0 - 3016447.exe broke Console hosts 6.0 ESXi and ESXi 5.5 fixed it for me.

• Store of data sharing between 4 ESX and ESXi 5

  Hello

  I have a vSphere environment 4.1 with a vCenter and a cluster of 3 ESX 4.1 access to the content of data through fiberchanel (type scneario) warehouses.

  And now I need to install a new ESXi 5.x (cannot be a different version) in a separate environment, outside of the current vCenter, BUT to access the warehouses of data even as the cluster of vSphere 4 current.

  Anyone know if there should be no problem sharing between 4 ESX and ESXi 5 access to the same data storage?

  Thanks in advance

  As long as the FC zoning is configured properly, avoid all the problems.   ESXi 5 will be able to see the data created by ESX4 VMFS3 stores, it will not be able to create the same size of virtual machine he can on a 5 VMFS datastore.

• vMotion between hosts 4 ESXi and ESXi 5

  I have a group of ESXi 4.x hosts connected to a vCenter Server 4.1.  I have an another 5.1 vCenter Server Management 5.1 hosts.  I want to move my hosts ESXi 4.1 in my 5.1 vCenter Server and upgrade to 5.1.

  Since vCenter 5.1 can manage ESXi 4.x and 5.1 hosts in the same cluster (KB VMware: upgrading vCenter Server 5.1 recommended)

  Could I add my 4.x hosts to vCenter 5.1 and put them in maintenance mode one by one and then upgrade?  I'd be able to vmotion the VMs between my 4.x and ESXi hosts 5.1?

  The goal is to reduce or hopefully elimate downtime for virtual machines.

  Thank you!

  You can get the upgrade with no interruption of service, if you can:

  (a) connect the storage 4.1 hosts FC 5.1 guests, so it is shared by all hosts

  or

  (b) your license allows you to storage vMotion the VMS to storage of 5.1 hosts

  The normal steps would be:

  -Disconnect the 4.1 hosts the vCenter 4.1

  -Connect the 5.1 vCenter

  -connect storage 4.1 for the 5.1 hosts or Storage vMotion the VMs on

  -vMotion the VMs to 5.1 hosts

  -upgrade the 4.1 hosts

• AW17 R2, support Raid and Tweeking OC.

  Hi guys

  So, I had my R2 17 for about 1 month now, and I really miss support raid. because according to me, it's kind of waste that I have 4 x Crucial MX200 500 GB SSDs 2280 m2, in the laptop and I can't use them in raid.

  None of you don't know if it will come a bios update on this? and the option in the bios for OCing?

  A little *, dell has removed the option RAID and many other useful tips for this line Echo. When other computers laptops Alienware came with open bios.

  Thanks in advance

  Norway.

  Hello

  Unfortunately. We have not received any news on an update of the Bios that make this possible. Maybe it's an option that we will be able to add in the future for the Bios, but as of now nothing has been confirmed.
