• a few questions about ESXi and SAN CF with HP P2000 G3

  Hello everyone!

  I am new to ESXi and SAN, then I need help for her.

  I have Encolosure C7000 system with 4 blades BL460c already installed ESXi 5.1U1 (HP custome ISO image). Everything works fine now, but I do not understand something:

  -What is the management network which I use vSphare Client to connect to? It is a private network to manage ESXi servers what difference with VMnetwork used by Virtual Machines? Because I've set up an IP address for this connection manually, but it is of course separate with IP addresses, I used on Virtual Machines.

  -If my system has problem, so I have to reinstall ESXi, license keys can be used again? Already, I have 8 license key for 4 blades (2 CPUs per server), but they have not yet used. Because I am new to ESXi, cause I had to reinstall ESXi several times to understand.

  -When I install successful ESXi, I don't know how to start working with SAN. What should I configure P2000 before it be plugged into the SAN switch? Or I can plug it then config later? Because I don't see it on the ESXi server. And on the OS I installed on the Guest Virtual Machines, I see nothing new in Device Manager. I thought that this guest operating system will detect the mezzanine card. But I see only mezzanine card that connect to the P2000 by SAN switch in ESXi (see image here http://img203.imageshack.us/img203/684/dsc04088k.jpg ). To my knowledge, I think that ESXi server have to detect the P2000 as hardware device. Can someone teach me step by step install and configure a San on ESXi? Or show me a tutorial because I searched but only iSCSI results.

Because I've set up an IP address for this connection manually, but it is of course separate with IP addresses, I used on Virtual Machines.

  Yes, it's a separate network used only for traffic management between ESXi hosts and vCenter - it is also the network used to connect to the environment - that's different, then the network used by your virtual machines

  -If my system has problem, so I have to reinstall ESXi, license keys can be used again? Already, I have 8 license key for 4 blades (2 CPUs per server), but they have not yet used. Because I am new to ESXi, cause I had to reinstall ESXi several times to understand.

  Yes the license keys can be reused, and if you use vCenter licenses will be managed by vCenter

  Yes, you will be able to configure the San later - by default, the virtual machine will not see the SAn, as it is virtualized by your ESXi host - all the VM will see is a virtual SCSi disk - this doc's guide to vmware for storage - http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-511-storage-guide.pdf - you can visit the website of HP they might have documentation on configuring P2000 for vSphere -.

• P2V with SAN = > VM + VMDK

  I have a question:

  I want to P2V a physical server with data on SAN for stand-alone with VMDK on ESXi virtual machine.

  How can I do this?

  I think, I can:

  1. a hot P2V physical server with SAN = > copy entire disc VMware P2V tool
  2. Start a virtual machine with VMDK

  You will be able to use VMware Standalone Converter - it read the SAN as a classic drive and create a corresponding VMDK.

• Trunking VLAN directly from ESXi in SAN servers

  Hi all

  I think that I made a mistake in choosing to go down this path, see the details of the deployment:

  the installation of the failover network limited bandwidth to a single link (failover) instead of 2 Gbps, which can improve performance.  as the solution of trunking VLAN, however out of despair and the stress very load high,.

  I was thinking of redesigning the network all over again from scratch, using the trunking VLAN directly from Server ESXi in SAN to use 2 x 1 GB Ethernet

  cable to enhance the delivery of data to the VM without the use of any

  switch between SAN and servers.

  What is a possible solution using 2 x ESXi and iSCSI MD3000i SAN?

  Kind regards

  AWT

  Since the SAN has only had 2 NIC by controller,
  + so I guess I can provide only 2 Gbps maximum for the ESXi server +.
  + each using trunking VLAN and leave the rest unused switch ports used by the other server. +

  MD3000i does not aggregate links (like Equallogic, for example), but works with MPIO.

  MPIO ESX is NOT able to aggregate links, but he is able to use the different path for different LUN.

  So the solution is simple build at least 2 LUNS, and working with different path (the path is normally automatically selected by ESX)

• Permissions to connect to esxi with perl sdk

  I tried the user scripts perl for surveillance. I have 1 Server ESXi 5.1 I can connect to directly and the script has no problem connecting.

  I have another 3 esxi servers which are connected to a server for vsphere.

  On the same server, I can connect directly to the server esxi with vsphere client no problem.

  On the vsphere server, I can only connect to the server for vsphere, I can't connect directly to the esxi hosts. (http, https, ssh, etc...)

  I think it's the issue that I have with the sdk for perl. I have a SSO connection that I can user to connect to the server for vsphere, but these permissions will not get access to the esxi host.

  Anyone have any ideas on how to solve this problem?

  Thank you

  I'm really not sure about the writing of scripts and other things, but if you need to create local users in ESXi host, you must connect to the host directly and then go to the tab of local users and groups and create users.

  

• Virtualize a physical machine with SAN-attached storage

  Hello

  We are looking to virtualize a physical machine in W2k3 with SAN attached storage.  Ideally we would like storage as RDM due to migration, is possible without destroying all the data that is held on this subject?

  TIA

  David

  Just use converter for local disks.

  Then map your SAN disk to your ESX (masking of storage).

  Rescan ESX to see the new LUN (under the storage card).

  Finally add the virtual machine to the RDM disk (use virtual mode to use instant VMware).

• Migrating from 5.0.0 free ESXi / ESX 4.1.0 a local database to bought ESXi 4.1.0 with SAN

  We currently have four host servers.  Two host servers are the free version of VMware ESXi 5.0.0 and ESX 4.1.0.  I have two hosts in a cluster, obviously with the version under license and running VMWare VCenter ESXi 4.1.0 running.

  All of these guests have all (vmdk files etc.) data stored locally on the host servers.  I'll be migrating to a new SAN and buy under license of VMware.

  I need to move the virtual hosts free version VMware servers (5.0.0 ESXi / ESX 4.1.0) to the cluster host ESXi 4.1.0 under license.  I can export the folder containing all the files and import it on the cluster license.  Once records are there, how can I activate the servers of records and pull up?

  I have to get off these hosts old existing virtual servers on the new servers which we you place your order.

  In this case I the new environment configuration and then for example use VMware Converter to migrate (V2V, with the virtual machine is turned off) the virtual machine of the former hosts in the vCenter Server environment allowing you to select the target storage.

• SMB ESXi with iSCSI SAN

  I'm looking for make a SMB deployment for the clients of mine. The new features offered by 4.1 for SMB as VMotion and HA are now in their budget. I've seen DELl offering some broadcom with TOE and ISCSI unloading cards. I know that 4.1 now supports TOE cards, but these broadcom cards actually iSCSI HBAs or just TOE cards Motors iSCSI? VSphere 4.1 will support this card? Its much cheaper than buying full host bus adapters blown for a small business.

  I'd go with the R710 mainly because of the experience with the model and how strong they are. You will save all the money using the R610, so you could spec on a solid R710 for the host. In addition, the R710 has four GB of NETWORK map (with the option of TOE on the four) and four open expansion for multiple network interface cards and other slot. With the R610, you will have only two expansion slots. So if you want to add more cards later (more than two), you must either delete that you installed to make room, or do the purchase.

  I would always use the SAS drives on board to install ESX/ESXi on. You will save money by not getting NOT the HBA you can use to boot from SAN with the same (or similar) performance level. It also helps to isolate the questions when you're starting from local disks... I would go with a pair of 10 k / 15 k RPM SAS drives (2.5 "or 3.5", your choice there) on the RAID controller (using RAID 1 on them) support. Confirm with either your VAR or rep Dell to make sure that the controller is 100% compatible with VMware (or you check the HCL). They list the 146 GB drives in the Configurator (normal site of SMB) fairly cheap price.

  I'd also go with processors Xeon E5620 (get a pair inside the host) so you'll have plenty of CPU power. Get as much RAM as you can, using not more than 12 sticks (multiple of six).

  In fact, I have configured a R610 and R710 a using the SMB website... The R710 has the 146 GB (10 k RPM) drives the R610 has 73 GB 15 k RPM drives. The R610 comes out to almost $300 more than the R710. We're talking same memory (24 GB), TOE enabled on the built-in NETWORK interface, no additional NIC at build time (they would get another provider, getting Intel NIC, NOT of Broadcom), redundant power supplies, kits of rapid-rail (without the wire management arm), two-processor Xeon E5620, iDRAC 6 Enterprise (so you can do it all remotely, no need to use any KVM don't setup once configured the iDRAC 6). Both versions include the 5 x 10 hardware only (NBD onsite) support. I also put the hard drives RAID 1, so you have redundancy here.

  Seen readers on board, for ESX/ESXi is on will also configure the host much easier and will not require something special on the side storage. Otherwise, you need to configure up to the MD3000i to present the solitary start-up LUN to a host for ESXi. Everyone that I spoke with who implements guests, always with local disks. Especially if you are looking to save the ~ 1 k $ the HBA adds to the build (not to mention the extra complexity to things). I was talking with some people in charge of a large IBM virtual data center not long there. They were forced to boot from SAN on their hosts fear. They were forced to do so by higher ranking people within the company. It was decided that because it sounded good on paper, it would be good in practice. Initial tests have shown how much pain he would be, and they were not happy about the extra work required so that it can happen. Until VMware clearly indicates that booting from THE SAN is recommended to local disk (properly configured on either) I will continue to use local drives for ESX/ESXi reside opon. Even in this case, we have a significant performance win by going to the boot of model SAN. Maybe when 10 GB is on the environment as a whole, it will make sense. As it is, you get new SAS disks that are 6 GB, everything in-house, and you still beat the trunk of the SAN performance model. In addition, you don't need to worry about someone making something accidentily to the LUN you are booting from...

• Free EsxI - use with SAN

  Hello

  As a system administrator, we will began to plan the installation of our new servers and two new solutions Equallogic SAN. We bought two enterprise license of VMWare infrastructure (which was recommended through our hardware vendor).

  In our meetings, I have discussions with my Chief, why we do not use the free version of EsxI, because the business version is expensive. My hardware vendor has reported that us can' use the free version to store vmdk on the SAN files.

  I searched for information, but I couldn't find anything. Can anyone help me give some information why we should use the free edition instead of the Enterprise edition? Next to vmmotion, high availability, etc.

  THX

  The free version works perfectly with an Equallogic SAN.  What you get with the Enterprise version is the ability to use VMotion and HA and Virtual Center. Moreover, VMotion and HA require Virtual Center, so if your vendor sold you only licenses the company without a license of Virtual Center (also expensive), you're really at the point where there is virtually no difference between the Enterprise and the free version.

• Single node ESXi with large local storage

  I have a HP DL180 G6 loaded with 2 160 GB drives, in the opposite direction. I'm also 6 2 TB disks in a RAID5 configuration including a spare drive (approximately 7.4 to useful).

  What is the best way to take full advantage of the direct storage of this machine?  SAN/NAS isn't in the budget.

  Currently, I have install ESXi sitting on the 160 GB mirrored drives and thought I'd get to use all of the 7.4 to other readers as a local data store, but only the instalation disk ESXi shows upward, the other readers that have been configured to RAID5 but do not appear in vsphere.

  Thank you.

  What RAID controller do you use? E200/P400? There BBWC/FBWC?

  To be able to use the full 7.4 to with ESXi 4.1 you must divide the RAID in several logical volumes, smaller than the maximum supported size 2 TB less than 512 bytes. To do this, boot from the CD/DVD of SmartStart and run the ACU (Array Configuration Utility). Once completed, start the new ESXi and use the "Add storage" Wizard to create VMFS storage of data on the logical volumes. Depending on the maximum size of virtual disk that you plan to use, you should consider to choose the appropriate block size while creating VMFS data warehouses.

• How to create a database with SAN storage?

  We are creating a new database, but what we need to do is to configure the oradata, admin and data files directories in SAN disk. In the same system, we have created two database in d drive so we can't change the oracle home

  1 create a LUN on the SAN

  2. mounting LUN on your Windows system

  3. the format of the LUN with diskpart.

  4. at the moment, you can move your database to san lun. This can be done in different ways. For example:

  stop immediately;

  bootable media;

  #move # your files from A to B physically db #.

  ALTER DATABASE FILE RENAME ' C:\oracle\oradata\theDatabase\

  'to' Q:\myDatabases\theDatabase';#rename all files moved

  ALTER database open;

  ALTER database backup controlfile to "/... /... /... /';"

  ALTER database backup controlfile to trace.

  # a full backup (if log mode archive) warm/RMAN or stop again and take a cold backup if no archive log mode.

• config of memory in esxi with a hyper-v virtual machine on.

  First of all, Thanks for the help.
  
  I set up a Home Lab with ESXi 5.1.
  J’ai several Linux machines. J’ai a virtual machine Windows Server 2012 Hyper -v.
  I would like to know what the optimal parameters in order to maximize the 32 GB of RAM to the virtual machine Windows. ()when I use this machine do not use any other ESXi virtual machine)
  J’ai not clear that if administered dynamically memory for this VM in ESXi when you manage Hyper v, dynamic Management of memory will be use all the RAM.
  
  Thank you for everything, I hope that I have explained.

  How much memory is your ESXi has? If you have not set up a special configuration for the virtual Windows machine, the ESXi Server uses the common techniques of overcommitment with the virtual machine. If you have more than 32 GB of RAM on your box of ESXi, you'll never overcommited (assuming that your other virtual machines are turned off). So the ESXi will give access to the physical to your Windows virtual machine memory as long as she asks for.

  You can also ensure the physical to the virtual machine by using reservations memory, if you want to.

• End end NIC Teaming on ESXi with redhat linux guest operating system

  I'm running into a situation of lack of bandwidth for my backup server running inside the virtual machine environment. To increase bandwidth coming from a number of backup clients on my backup inside ESXi 5 server. I would like to collage x NIC 2 inside my redhat Server installation and train the grouping of NETWORK cards using Hash my ESXi host IP.

  What is the feasible way to provide a 2G from end to end connection to the outside world for my redhat backup media server? or there is an inverse?

  I don't think you need to add a second NETWORK card to the Redhat VM, which acts as a backup server as a single for the virtual computer NETWORK adapter can accommodate more load than 1 G.

  I have a couple of Redhat with a single NIC servers. VMXNET the following example shows this ethtool sees for the NETWORK adapter on one of these Redhat servers.

  [sfuller@rhel7 ~] $ sudo ethtool eth0
  Settings for eth0:
  Supported ports: [TP]
  Supported link modes: 1000baseT/Full
  Supports auto-negotiation: no
  Advertised link modes: unreleased
  Announced the autonegotiation: No.
  Speed: 1000 Mb/s
  Duplex: full
  Port: Twisted pair
  PHYAD: 0
  Transceiver: internal
  Auto-negotiation: off
  Link detected: Yes

  When I run a transfer TCP (using thrulay) from one server to another, you can see that it is 2.6Gbps average on the transfer of 10 seconds.

  [sfuller@rhel7 ~] $ thrulay-t10 rhel6

  (0) # 10,000 0.000 2687,479 0,280 0,566 202.781

  So this shows that we can get more than the throughput of 1 Gbps on a single "GE NIC" on a Redhat VM.

  You will need to do is, as you mentioned, change load balancing on the host than the Redhat VM ESX runs using the road based on the hash of the IP. This will allow the Redhat VM to use more than a single teddy bear on the ESX host. You also need to several customers, including LSB of their XOR IP addresses differently, but you said you have several clients and so unless you're really unlucky with the IP addresses to clients have you should be good there.

  I hope this helps and good luck.
