• SAN - RAID set

  Hello

  I am a newbie to vSphere 5 & am in the process of setting up a test lab. I use 2 x ESXi5 (HP 380 G5) hosts & an iSCSI SAN (380 G5).  I'm not sure of the best configuration for the entire SAN RAID. I would appreciate some recommendations on the best way to configure this small SAN lab.

  Should I create 1x1.4TB than defined R5 or a 2 x 700 GB RAID 5?  A configuration is better than the other?

  He is create 2 LUNs, one per raid array & a VMFS per LUN. I may be running on the 5-7 VM per LUN, none of the VM being I/O intensive. The hosts does not also start from SAN.

  SAN Configuration (HP 380 G5)

  2 x DUAL core CPU Xenon

  16 GB OF RAM

  1 X P400 controller

  2 x 72 GB - RAID 1 (OS - ESXi5 + Open spinning)

  6 x 300 10 k SAS = 1.4 TB in RAID 5

  Concerning

  Bob

  I create a unique set of RAID5 with all 6 discs (or 5 drives + spare), and use the ACU (Array Configuration Utility) to create at least two logical volumes on this RAID set. Although it is not necessary to create multiple volumes from a technical point of view, this configuration will allow you to 'play' with features like the migration/storage vMotion in the lab environment. BTW. you will have a much better performance of disk with BBWC (512 MB or more) for the RAID controller.

• Installed build 5.1.0a vcenter number has not changed

  ISO, I improved 5.1.0 to 5.1.0a Vcenter.  Simple installation wouldn't work so I installed all the separately from the components.  Upgrade went to and I rebooted.  Now, when I check the build number in Vsphere client it says still 5.1.0 build 880146.

  So I try to install it again, but now I get that remove\uninstall options.  The build number is the problem?  Anyone can check their version number after installing 5.1.0a?  It should be 880471.

  We did an upgrade on place of 5.1.0 to 5.1.0.a. The build number does not change when you click on "Help-> About" (we also 5.1.0 880146) but if you look in install logs and you will see that the versions of the files have changed even if the build number property does not have the versions of files.

  Example of C:\ProgramData\VMware\VMware VirtualCenter\Logs\vim-vcs-install.log

  ---------------------
  5.1.0 installation:
  Company: VMware, Inc..
  Product name: VMware vCenter Server
  Product version: 5.1.0. 32743
  5.1.0a install:

  Company: VMware, Inc..

  Product name: VMware vCenter Server

  Product version: 5.1.0. 33762

  Example of C:\Users\myuser\AppData\Local\Temp\vim-vcs-msi.log

  --------------------------

  MSI (c) (18:18) [19:26:56:171]: product: VMware vCenter Server - Configuration completed successfully.

  MSI (c) (18:18) [19:26:56:171]: Windows Installer reconfigured the product.

  Product name: VMware vCenter Server. Product version: 5.1.0. 33762.

  Product language: 1033. Manufacturer: VMware, Inc. successful status or reconfiguration error: 0.

  The real vcenter vpxd.exe change 5.1.0.32743 to 5.1.0.33762, see picture attached.

  So it seems that it has been upgraded successfully, but they just don't update the build number of vCenter property. Other indicators of success, it's that if you surf to the VirtualCenter new and download the vSphere client, it will install the files for a new client with the 860230 build number.

• ASM vs San raid which to adopt

  Hello
  
  We have a system using ASM and San drive. San has a hardware raid, while the DSO has also do the same thing. Because according to my understand its function. Strip and any mirror. Do you think we have several raids in the system and we should disable hardware raid. Also I thing hardware raid is raid 4. Please correct me if I'm wrong
  
  concerning
  Nick

  RAID 1 + 0 or 0 + 1 is an implementation of striping and mirroring.
  RAID 5 is an implementation of aggregation by band with parity (where the parity strip is scattered between the discs, with RAID 4 parity stripes are on specific disks)
  See: http://www.baarf.com

  Please, mind, than the baarf Web site focuses on the decrease in performance (writing) of the use of RAID levels with parity. Even with the SAN, it is still quite true. (it is inherent on the way to parity is implemented)

  ASM normal redundancy is essentially a mirror application. The implementation of normal redundancy ASM subtly different way works mirrored RAID.

  This means having RAID 1 + 0 / 1 + 0 on SAN level is a way of mirroring, and having normal redundancy ASM is another way to have copies mirror blocks, which would mean that having RAID mirroring on the normal SAN and level of redundancy at the ASM level means you have 4 copies on the same storage box.

  So I would say that there is little benefit to have normal redundancy ASM on top a stripeset mirrored.

  As an adviser what to do: most ASM implementations use external redundancy, which means the redundancy of the San is used. I think it makes sense.
  With the help of normal redundancy makes sense when you use local drives (non-RAID), or when having multiple SAN.

• What is the maximum number of data warehouses in a system of Vcenter?

  What is the maximum number of data warehouses in a system of Vcenter?

  I had a look at highs of configuration in http://www.VMware.com/PDF/vSphere4/R40/vsp_40_config_max.PDF , he lists100 in the section of SMI-S

  SMI-S section list max number of ESX host as 100, although it is 300 in the maximum of vcenter server. Should I look for in the section of SMI-S?

  Only if you plan to use SMI - if she does not go with the maximum rates for vCenter - and you are correct to look at the number of hosts since it is the ESX hosts that communicate to the SAN not vCenter-

• vDS and vCenter Server on SAN

  I have a very specific question about it as possible.

  I have 3 guests with no local VMFS (ESXi installed on a Flash cards) and all data warehouses are on the SAN.

  VCenter Server is a virtual machine residing on the SAN.

  SAN access is configured with iSCSI connected through a vDS.

  What would happen if there is a power failure?

  Say that I turn on the SAN first, then try to power on the hosts, the hosts would have access to the San while vCenter Server is still off powerd (and because it's aVM)?

  Thanks for your understanding!

  On VMware ESXi ESX, the vDS configuration is saved on /etc/vmware/dvsdata.db. The file .dvsdata of data warehouses are used by HA and stores some information as the State of the port and its stats.

• vCenter 5.1 U1 strange build number - 1364037

  I've just updated by vCenter 5.1 5.1 Update 1, following the recommended procedures.

  The strange thing is that the build number is now watch, it is not what is expected and also does not appear on the list of the numbers of official version here VMware KB: correlation vCenter Server and ESX ESXi host build numbers to update level

  My build vCenter number indicates the version 5.1.0 build 1364037

  Any ideas?

  It is the build number for the latest version of patch for 5.1U1... It is therefore correct. Maybe the KB should be updated.

• Snapshots created with the EqualLogic VSS provider are not displayed in SAN HQ

  Hello

  Poster for the first time. We have just implemented an EqualLogic SAN, PS6100X network, and we're having performance issues between our DPM backup server, one of our hosts Hyper-V and VM images stored on the San. I will try to provide as much information as I can

  Environment:

  Dedicated iSCSI using Dell Force10 switches network

  hyper-V (Windows Server 2008 R2) 3 hosts
  -2 hosts has a NETWORK 4 port GB dedicated adapter connected to the iSCSI network; 1 host has connected to the network iSCSI NETWORK 2 GB dedicated ports card
  -Each Hyper-V host computer has a dedicated on the EQ SAN, RAID-50 volume that stores the Hyper-V virtual machines
  -EQ VSS provider installed on all hosts Hyper - V 3 and works correctly

  Using DPM 2010 for backup

  Problem: on Hyper-V hosts 1 and 2, any/all backup activities are very slow. On the Hyper-V host 3rd, however, activities related to backup all are incredibly fast! We compared the NIC configurations, HIT / settings ME and ASM, but we cannot understand why it is so slow on hosts 1 & 2.

  In addition, whenever DPM 2010 tells the EQ VSS provider to create a snapshot, we see the snapshot being created in the EQ Team Manager, but he does not appear in the list of iSCSI connections. According to the documentation SAN HQ, instant and volumes should appear here.

  We also disabled TcpAckFrequency for all 3 hyper-v hosts. It helped a little, but there is still a HUGE difference with regard to backups of the DPM.

  We're pretty sure that there is something misconfigured on the hosts Hyper - V 1 & 2, given that the host Hyper-V 3 has no performance issues.

  How can I get snapshots to appear in the list of iSCSI SAN HQ connections?

  Version information:
  SAN AC = 2.2.0.5924
  Storage Array Firmware = 5.2.4

  There are two different issues in this post for the SANHQ doesn't show only not iSCSI connections.

  Now SANHQ displays the correct total connection number but doesn't provide details of connections individual iSCSI for snapshots, which it should. So in the meantime use Workgroup Manager that shows the details for each snapshot (I know that's not the best answer, it's a short term solution).

  The fact the SANHQ shows details of instant connection does not mean that they aren't here and I can't imagine anything to do with the question of the DPM.

  The real difficulty, look for upcoming beta SANHQ and subscription for this on the EQL support site. You can do it now.

• Migration of data to assist based SAN store

  Hey guys,.

  We have two esx servers. ESX1 and ESX2.

  ESX1 is autonomous, while ESX2 is with a SAN (connected to the HBA fibre channel)

  I am now loading on ESX1 vcenter, once this is done, I want to move the VM ESX1 the ESX2 server machine, BUT this time it should reside in the SAN logical unit number.

  I know that I can't move without interruption because they have not San already, so I'll have to cold migrate virtual machine to esx2 esx1 but is it the same as usage of vconverter? Also if I migrate can I ask vcenter to load the machine in the logical unit number of the san and not on the esx2 data store?

  Please help, I really need to get the VMs on the San and not having to build them from scratch once again.

  Thank you

  RJ

  We will all live a virtual life...

  OK

  The fact that you are directly connected to the San, and you can see the LUN in the section maps storage equates not once he is able to do something with this LUN.

  You must go to the STORAGE (should not be confused with storage adapters) and add it to your server AGAIN.

  When asked if the physical storage disk/LUN or connected to the network, you select disk physics/LUN. You will be presented a list of LUN storage adapters can see (including this LUN you're talking 200 GB)... Select it by clicking on it. Then, you will be asked to select the size of the block... I would recommend selecting 1 Mb. Then, you will be asked to give it a name (something like Datastore1_From_SAN works well) and then the server create a VMFS partition on it. Virtual machines LIVE in a VMFS partition - without one on this SAN LUNS, you will not be able to migrate your VM to it

  It will then appear in the tab for data warehouses (according to my pic) on the summary page of your server and appears in the page of DATA storages as well

  Hope this helps

• Go Local to SAN storage

  I just finished the configuration and the connection of our new Dell's IScsi SAN (Equallogic) to one of our guest VMS (ESX 3.5) and created a SAN logical unit number to contain virtual machines.  I have also attached the LUNS to the host of the virtual computer so that on the host computer, I now have local storage (where the virtual machines currently reside) and the joint LUN.

  What is the best way to move the virtual machines in local storage to the LUN?  No offense, but I don't want to make a bunch of Linux commands at the level of the command prompt.

  Thanks for any help.

  Hello

  If the virtual machine is running, and you have vCenter, use SVMotion.

  If the virtual machine is turned off, and you have vCenter use Migrate.

  If the virtual machine is turned off and that you do NOT have vCenter using VMware Converter.

• Help: update/fixes Essentials, no SAN no host Update Util

  As very probably know VMware in their infinite wisdom have discontinued support and development of Host Update Utility in v4.1.  I currently manage an Essentials environment with DAS only (without SAN), and VCenter installed as a virtual machine on a host.  In the past, I have always used the Util to update host patch and update of my hosts.  Instead of this change, it seems that the only options are manually fixes using vihostupdate or install or use Update Manager.  The latter is useless for us since we do not have a HOLY and cannot update the host who would be Manager update as a virtual machine (no both VMotion etc).  In the past, I would just run host Util update, do check it out for the latest patches of VMware, and then run the patch install - he took care to locate the patches and apply them in the correct order.  What is the best game plan now that this util is gone?  Where can you easily check the patch repository, download the correct patches and apply them in the correct order?  Maybe I missed something, but would appreciate anyone entry on the correction of strategies in this scenario.

  Yes, you can apply all the patches together and atlast you can go to restart ESXi

• Help Setup RAID SATA for ESXi 4.1

  Hello

  It is the first time that you try to use vmware.  Any help is greatly appreciate!

  I just built a server around the Intel s5500hcvr mother. I have 6 SATA HDD I want to set up in a RAID. The integrated RAID controller seems to be very limited and does not seem to be supported by ESXi 4.1 (when I run ESXi 4.1 installation and it asks for a location for installation, all my discs are individually listed instead of virtual drives that I created with the RAID controller)

  My questions:

  (1) what is the suggested configuration of HDD (RAID levels / number of berries) for ESXi 4.1?  Can I create 1 RAID 10 array and set everything up to that?  or take one of my disks and install esxi 4.1 on it and then create a RAID with the rest of my discs and use it to store data?

  (2) anyone can provide links to some SATA RAID controllers that are known to work with ESXi 4.1 (and is the supposed to recognize virtual readers created by the RAID controller setup ESXi 4.1)

  Your motherboard has a RAID controller software which, as you have discovered, is completely not taken in charge by ESX/ESXi... You will need to get a RAID controller that is on the HCL for SAS and SATA hard drives (not one with battery backup write cache) so you can use any type of RAID configuration.

  My preference for Internal RAID configurations (on the host) are two drives mirrored for ESX/ESXi to reside (preferably being SAS 10 k or 15 k RPM, 73 GB or 146 GB in size) and then another table for the data store. You'll want to keep the data slot store table 2 TB-512 b size in order to present to ESX/ESXi as a LUN. Or you will need to get a RAID card this split of the support to the top of the table in the smaller of the virtual drives that can be presented for ESX/ESXi and LUNS.

  Search for controllers using the LSI MegaRAID chip as a good first lap. Some Adaptec cards should work, but I've seen people post questions on those recent (more recent than in the past). MANY manufacturers rebrand/efficiency the LSI MegaRAID Controllers server, such as the Dell PERC 6 series cards.

  For the use of 4 disks SATA, RAID 10 (on a BBWC, fully supported, controller) will give you the best performance. It will compare with SAS drives however. IF you do not plan on any virtual machine running with anything beyond light IOPS / s then you should be ok (or with very light loads)... If this is going to be a production server, then get the SAS drives all around.

• Best Senario distributed virtual machine between SAN LUNS and replication fail over Senario

  What the best best Senario for the installation of virtual machines on Big LUN or each VM on LUNS dedicated:

  We planninig to implement 70 virtual machines on Esx 3.5 servers with replication LUN usisng CA of HP 7.

  using 4 Big 800 GB data store on SAN RAID 5 Lun (each LUN will be contains 16 VMS)? or each VM will be deployed in separate small LUN 50 GB data store on SAN, RAID 5 and that this effect on the failure during the procedure on the DR Site if we choose BIG LUNs, also if this virtual machine includes 3 disks (store them on each disk on the different data store or the same data store)

  Thank you

  Remember that the virtual machine is a set of files and these files directly in your data store.  If you have a large store of data with multiple virtual machines, you must replicate the full data on the alternative site store in order to get to that data.  You can't really use greater SAN replication for just the simple vm in a data store.  SAN replication is not really aware of what is stored on it, she replied just blocks he knows.  You can copy the vm files individually as well, but it's more than a copy and not replication.  Otherwise, if you are concerned about vs some other vm, then using a small LUN would work better for you, or warehouses of data at multiple levels allows you to replicate the vm that are important to you and put the rest in a larger data store.

  FCIP/FC/IP doesn't really matter.  Until a table can talk to each other, you're fine.  Our secondary site is hundreds of miles away, and replicate us very well during the period of INQUIRY, from one table to the other.

  Yes, without SRM, you will need to manually register a virtual machine at the time, or write a script to work through all the.

  You might consider updating the controller firmware (after are updated BIOS, ESM and the controller driver), which controls the State of the battery.  Otherwise, the battery that you accessed should be good... it is not really other "types" of batteries that will work.

• Dell PowerEdge 2950 P2V problem

  Physical server:

  Dell PowerEdge 2950

  Windows 2003 R2 Standard x 86 operating system

  Sheet music:

  Dell - hidden partition

  C: BONE

  D: Data1

  E: Data2

  G: data4

  vSphere ESXi 4.1 (under license)

  ISCSI SAN

  vCenter Server

  I tried on cold hidden server with boot CD, but received the error "unable to determine the operating system invited."  Looks like that I don't have the driver for the Dell raid controller in the boot CD.

  I decided to go with the hot P2V using the plug-in for VirtualCenter.  I stop the SQL server service and disabled the firewall disabled the anti-virus tools.  Only two partitions (C and G) on the physical server must be in the new virtual machine.  So, I've selected partitions C and G and has increased the size of the drive at a time.  I made sure not to install the vmware tools and unchecked the option reconfigures.   The P2V conversion was successful.   But when I went to start the virtual machine, it starts with the 'VMWARE' logo and restarts immediately.  Restart the virtual computer so fast I can't even in the BIOS unless I hit the key several times.   I did the clonning with the hidden partition, but with the same problem.   There are no BSOD or any indication that the virtual machine cannot find the vdisks.   Called in vmware support.  They used webex for an hour, but could not fix.  Asked me to send in the logbundle.

  I HERE it if someone tell me what I am doing wrong?

  Thank you

  Another option is to install the Standalone Converter 3.0.3 on the PowerEdge, stop all services and performing the conversion.
