• Numbers: How lock the table without blocking the ability to edit what is inside?

  everything in the title

  Thank you

  Hi Berendirih,

  Is not possible. The lock table prevents changes to the table and its contents.

  Whenever possible, you should separate entry and calculations on their own tables. Lock tables calculation in order to protect the formulas. Leave unlocked data input tables to allow data entry.

• iSCSI SAN Connectivity

  I'm kinda new to this Yes, you can be sweet.

  We are migrating some of our less critical servers to VSphere. Because the servers are at camp, we'll install eSXI on our server and use hosted camp via iSCSI SAN. The camp provided us with a block of IP addresses that we can use for SAN connectivity.
  SAN connectivity is on it's own dedicated NIC (1 for testing purposes) and physical switch.
  Management network
  192.168.72/24
  SAN IP blocked
  172.26.11.0/26
  172.26.11.1 - GW
  The target IPs
  172.31.3.105
  172.31.3.109
  I created a virtual switch for iSCSI and tied a physical NETWORK adapter to it. I then added the iSCSI adapter software, responsible for the target in the dynamic, linked discovery the NIC to the iSCSI Software card.
  I then added a road 172.31.3.0/24 to go to 172.26.11.1.
  When I scan for the storage of the new, I just blank. If I go back into the adapter software, targets are now listed on the static discovery tab. The camp is saying that their HDS does not all applications.
  So I built a virtual Windows machine and loaded on this host (using an Openfiler iSCSI on the management network) and installed the Microsoft iSCSI initiator. By using this software, I am able to connect to the SAN CoLo network from inside the virtual machine.
  What Miss me? Why can I not connect to the network the host SAN? Any help will be much appreciated.

• ESXi 3.5 4 problem to upgrade by adding the VMFS partition existing on iSCSI SAN

  Hi all

  I've got 2 x Dell PowerEdge 2950 III linked directly with Dell MD3000i iSCSI-SAN and today I had once hard to improve my production ESXi 3.5 u 4 ESXi 4.0,.

  First is that the upgrade is failed miserably after following this thread: url = http://communities.vmware.com/thread/211413;jsessionid=47217F9BCCA2DF1325DBE7A266D48A8D?tstart=0VMware communities: error on upgrade the host: this host is not compatible with this upgrade. [url]

  with the following error message: ERROR: unsupported boot disk

  The layout of boot device on the host computer does not support the upgrade.

  That's why I did a clean reinstall of ESXi 4 on top of ESXi 3.5 u 4 and lost all unique settings on my ESXi host. I am now stuck in SAN iSCSI partition mapping after following the guide from: http://support.dell.com/support/edocs/software/eslvmwre/AdditionalDocs/cnfigrtnguide/storage_guide.pdf [/ URL]

  See the following attachment.

  I wonder how people make their upgrade in ESXi 4.0 in the production system running ESXi 3.5 u 4 filled with hundreds of VM? The reason why I use 2 x ESXi server connected to unique SAN server, is that I can just start the virtual machine on the SAN from the other ESXi - & gt; that's fine and tested, but then when I rebuild the failed server, I need to delete all the data inside the shared partition that contains my VMs.

  So in conclusion after one of the ESXi server failed, mapping of iSCSI would eventually destroy all data in the partition?

  CMIIW, any idea and suggestion would be gladly appreciated

  Kind regards

  The configuration-> tab cards storage, you should be able to recrawl and find existing VMFS volumes.  You shouldn't need to add storage.

• question put on the vSphere iSCSI SAN infrastructure network

  Hi all

  We are a small company with a small virtualized environment (3 ESX servers) and are about to buy an AX-5 SAN EMC (model Ethernet not CF) to implement some of the features of high availability of vSphere. My question is related to the networking of the SAN: we switch dual Cisco 2960 G Gigabit and dual Cisco ASA 5510 firewalls in a redundant configuration.

  I understand that the best practice is to implement iSCSI traffic on a separate from all other traffic LAN switch. However, I do not have the knowledge and experience to determine the real difference than a separate switch would really vs the plan to create a separate VLAN on the switches Cisco dedicated to iSCSI traffic only. I would ensure that the iSCSI traffic has been on a VLAN dedicated Physics (not just a logic) with any other VLAN logical (subinterfaces) on the same VLAN). It is difficult for me to understand how a port gigabit on a VLAN isolated on kit Cisco will perform much poorer than on a dedicated Cisco switch somehow. But then again, I don't know what I don't know...

  The thoughts and the input would be appreciated here: I'm (very) hard not to drop another $6 + in another pair of Cisco switches, at least that this decision will significantly compromised performance iSCSI SAN.

  Enjoy your time,

  Rob

  You have 2 SP each with 2 iSCSI, for example:

  SPA: 10.0.101.1 101 VLANS and VLAN 102 10.0.102.1

  SPB: 10.0.101.2 101 VLANS and VLAN 102 10.0.102.2

  On your ESX to create 2 vSwithes, each with a port vmkernel on an iSCSI network and each with a single physical NIC.

• Cannot migrate VM on iSCSI SAN. Failure at the helm of the 10%. Peut vmping to all addresses

  Hello everyone

  Impossible to migrate virtual machines on iSCSI SAN. Failure at the helm of the 10%. Peut vmping to all addresses

  I recently installed a new configuration of the VM and I feel the above. My configuration is:

  2 HP DL380 with 1CPU 16 GB of ram and 500 GB shared space on iSCSI SAN.

  Installation of the network as follows:

  each host has the 6 network ports that is load balanced and fault tolrated in 3 VMSwitches. VMSwitch0 goes to 2 ports to shared resources on a 4510th cisco. On this switch, I use VLAN tagging to different servers that perform different functions. It works fine.ie. VLAN 5 is for the management vlan 31 is for secure vlan servers 37 is forinternal Web servers.

  VMSwitch1 is a vmkwenelport for the connection of iSCSI SAN. It is set on vlan 200 on the switch, so does tagging vlan put it. We have separated our san network ourusual networks.

  vmswitch2 is used for backup purposes and is used in a similar manner as vmswitch0. the ports of trunkied and backup services is vlan tag to go to the correct servers.

  I am able to ping betwneen the VLANS allowed. I can also vmkping to all the ip addresses of the two hosts san.

  What I can't do is to migrate direct customers between the hosts. He is still unable to 10% with the following error:

  Migrate the computer virtual iws3xx - pop1.mns.tlg.private a general error has occurred: the VMotion failed because the ESX hosts were not able to connect to the network for VMotion.  Please check your physical network configuration and settings network VMotion.

  No iSCSI traffic will work only if vmKernal and vmConsole are on the same vswitch. Maybe on the same vLAN according to how your VLAN.

• Should two switches for the installation of iSCSI SAN - be stacked

  I mean by "stacked" should they be hung by backplane?  Reference Dell passes, btw.

  Just two hosts connected to an iSCSI SAN.

  If the goal is to be completely redundant, your server is able to cable a physical NIC directly on each switch and your San can connect to both switches, there is no reason for the connections between these switches. Stacking of the switches can provide options for a large number of cases, but I don't think it will be here.

• How to get iSCSI SAN connected to ESX when the SAN is on a different subnet?

  Hi all

  I have two machines ESX which are directly connected to a San that are on a different subnet other network cards.  Other network cards are 10.x.x.x and the SAN is on 172.16.x.x, however whenever I try to add the iSCSI storage, the system will never find the LUN.  I put the vmkernel 172.16.x.x but it does not always find them.  I know that the LUNS are configured correctly if its ESX just having problems with the other subnet.

  You need to activate the Service Console to see the iSCSI SAN, too. This is because you use the initiator software. For example, you can add a second SC in the vSwitch that your VMKernel Port is connected and align on the same subnet.

• Planning the migration from DAS to iscsi SAN

  Hello

  We have a physical server running 6 VM ESX 3.5 (1 win SBS 2003 and linux 5) local SAS disks

  It's a 2xquad core clocked at 2.66 GHz dell

  now, let's add a second physical server (dell 2xquad core at 2.5 Ghz) and an ISCSI SAN: we would like to install ESXi on the second server and move all VMs on iscsi storage, so if the first server goes down in a few minutes we can manually set up the other to run all virtual machines (we are a small company and at present cannot afford the company/vmotion license).

  I ask for advice because we would virtualize an old physical terminal so win2003 Server (with 10-15 users, mainly working with MS office applications) using the second new physical server.

  This is the first time that we install a SAN (it's a dell MD300i with 10 disks 146 GB SAS, 5-disc SATA 1 TB for backup and snapshots) and we want to get the best performance out of it. Read the other posts, I understand that the discs are very important in a server virtualization terminal server and having good performance out of it.

  So, with this type of SAN and our workload, we should define a unique group of 5disk RAID with 9 discs and 1 hot spare, with a large ramdisk on it to create one or more data VMFS stores?

  or is it better to create 2 disk groups:

  -1 with two RAID1 disks for terminal server VM

  -1 with seven discs RAID5 for all other VM

  with a global hot spare disk?

  other general suggestions for migration, we will do?

  Thanks in advance

  Guido

  Yes, it's what I would do.

• Impossible to mount simultaneously multiple targets since a single iSCSI SAN iSCSI

  Hi guys,.

  I recently deployed FreeNAS 8.0.3 as a practice laboratory iSCSI SAN on one of my HP Proliant microservers.  The first target is a measure of physical disk since it was noted that the drive is faster than file extensions.  I have install the Initiator Software for dynamic and found discovery.  I built on that vCenter.  It was pretty slow going to see that it is also on a 100 MB network.  I decided to buy a gigabit switch and a 240 GB SSD.  I added the SSD as another target.  However, I can't get two data warehouses at the same time.  Am I missing something?  The two are listed under iSCSI Software Initiator...

  Connected targets: 2

  Features: 1

  Paths: 2

  When I'm actually in the paths, I see two targets, but only one can be Active (e/s) and the other is active.  To switch between data warehouses, I had to disable the currently active (e/s) an and the reactivate to failover to the other.  I wish that both target mounted at the same time.  How can I do this?  Thanks for any help.

  Mark

  My apologies in advance if I'm wrong understand something in the description of the problem, but it seems that you have only 1 "" meaning a block at the level of the device (iscsi) LUNS presented through two separate iscsi (two separate cobinations iqn/IP) targets. You can't have a VMFS in LUN data store so I am bit confused with your statement "I can't climb the two warehouses of data at the same time"...

• Several iSCSI SAN on different VLANS

  I have a little trouble to get this configured.

  In our environment, we have 4 guests and 2 EqualLogic iSCSI San. Each host has 3 NICs dedicated to iSCSI traffic, and they have been implemented to use the plugin for Multipathing of Dell with 3 VMKernel iSCSI ports, each bound to a NETWORK adapter physical and then linked to the iSCSI software adapter.

  We want to add a new SAN QNAP out some VMs test & dev environment of low cost data warehouses. The QNAP San not supporting Jumbo frames, we want to move them to their own VIRTUAL local area network.

  Can someone tell me how I can get this set up? I need of course a new VMKernel port running on the VLAN again, but after that I'm stuck.

  Thank you

  First: the initiator will be gracefully demote by using standard images.

  Second, there is nothing that prevents you from using the same trade for the qnap. If it does not manage the same way MPIO, you may need to add more exchanges and vmknics. If you place moderate to heavy load on the qnap it would interfere with the ability of the EMM to balance the load properly but allows to measure.

  We have a group EQL and a Celerra making MPIO in different ways. With Celerra you add several portals (ip addresses) network on different subnets so ideally you set up your trade in this way. For us, this meant adding a second portgroup and vmknic on each vmnic, resulting in a whole bunch of paths to the Celerra said. If our use of Celerra was far from being weak to non-existent I probably don't have it.

• fiber verses iSCSI San

  I'm looking for hardware recommendations on iSCSI fibre of verses for my vSphere infrastructure. We rotated VMware 3.5 for the past 3 years at the top of a HP MSA1000 SAN with Fibre connections for HP Proliant DL380 G5 ESX servers. We have between 20 to 30 customers of Windows 2003, all servers test and development, as well as two in the face of public web sites. We are looking to move to vSphere 4.1 and upgrade the hardware as well. I contacted HP and initially, they suggested the P4000 San, formerly Left Handed Technologies, but since it is I asked for a capable fiber of iSCSI option and they suggested the P2000. It turns out that the P2000 with all components (switches, controllers, disks, and support) will cost US $85 000. It's out of our price range. How iSCSI stack upward to the fiber? I heard comparable in performance. In addition, everyone uses the HP P4000 SAN and if so what is your experience. I hope to return in less than $ 30,000 for the SAN and devices.

  I am very fond of the P4000 series, after it is deployed and relied on them for a while.

  Based on the description in the logon message, I believe a P4300 would be much and should suit your budget.

  I warn you however, the P4000 series is flexible enough and there are many configurations and deployment options. Be sure to take your time and plan accordingly.

  That said, they have proven to be very efficient and reliable. I have always been impressed by the ability to unplug it (Yes, pull the power cables) unit in the table and not miss a beat. Then, when unity is restored, have all the data on the fly resynced. (Which implies a redundant configuration)

• HP SAS HBAS with IBM Storage and SAS SAN vs iSCSI SAN

  Hello, I am working on a project, and I have to add a SAN solution to my client infaestructure. My client already has a HP Server and we wanted to add another server, but an IBM one. I thought I'd add storage IBM (DS3200) that has two SAS interfaces. The problem is that the Distributor IBM says who does not know if the HP Server will be able to communicate with the SAS IBM storage. So, one possibility was to put on the server HP HP SAS HBA Controller. The second option is to put a SAS HBA Controller IBM. I think that the SAS is a standard, it doesn't matter what brand I use of HBA. Should not it works anyway?

  There is another option which adds instead of SAS one iSCSI storage. The problem is that I do not know the performance than the iSCSI storage. I want to put inside it's VM with Exchange Server (50 mailboxes), an ERP (for 50 users) with it's SQL Server, a computer file virtual, a virtual machine server with Active Directory.

  So, the questions are:

  1 - does anyone have experience with iSCSI storage to see if its performance if goog enough (I intend to use a dedicated to the iSCSI network gigabit switch)?

  2 does anyone know if I use different brands of servers (in this example an IBM and HP) with a SAS storage IBM? Who be it already done? The HP SAS HBA are compatible with the IBM iSCSI storage? IBM SAS HBA are compatible with HP servers?

  3. in the case of being able to do what I say to question 2, that do you suggest? Put a HP SAS HBA within the HP Server or upgrade an IBM SAS HBA inside HP Server?

  Of course the option I want to use is the addition of SAS IBM storage instead of using an iSCSI one, but I'm not sure of their compatibility between HP and IBM storage servers.

  Thanks in advance.

  In this case, the reason why I wouldn't use SAS is that your application requires this level of performance and the cost as not justified. You can configure iSCSI and direct savings in most important features such as snapshot, replication and dedup. If you were available to this solution with the DS3200 spend you 10K and that none of these features. Performance is very good, but you will find that the system is not yet warmed up with this load. The SAS Protocol can support high IO, but is not what provisions IO, is the number of disks and the RAID mode that defines your ability to e/s. I put 40 K terraced small IOPS / s on a single caching of 1 GB iSCSI target, so he can make the e/s. flow is not as high , but do you really need it. In the future you can profitable move to 10Gbe if you find insufficient bandwidth, which would be faster than the SAS 3 GB limit that is uneconomic to upgrade 3 + times.

• Beginners Overview: ESX to an iSCSI SAN servers

  Hello

  I hope I have the right section of the forum to do this, basically

  I'm trying to understand how VMWARE ESX server (3.5 if it is one)

  the difference) would connect to a SAN and what benefits it would be

  provide.

  Apologies if it's really basic, I'm new to both without and VMWare

  ESX so I'll try to understand all the concepts, I tried reading

  the articles, but they are a little dry for me.

  As I understand it, installing it would be something like

  this:

  Physics:

  ESX Server & gt; initiating hardware iSCSI (does not support

  (software?) & gt; cable network & gt; Turn on SAN & gt; Drive auto.

  Logic:

  Something like the creation of a LUN on the SAN itself (via the SAN web page) then use

  customer of VI to point to for a data store? Or is there some control of ESX?

  It would make sense that images of OS VMWare store customers

  on local disks to the ESX Server, so they start from all drives, in which case the SAN is down, then

  have the discs on the virtual machines stored on the SAN? Or will keep you

  everything about the SAN outside the ESX itself, which could at least

  remain separated from the SAN?

  Any help is appreciated.

  The main reason to use SAN storage is to provide shared storage so that you can take take advantage of features order higher than VMware provides as vmotion - the ability to move a running virtual machine form an ESX Server to another with no downtime for users of the virtual machine - DRS based on vmotion allows ensuring that the vms system receive the memory and cpu resources , HA that allows the virtual machine restart on another ESX Server.

  The physical scenario you describe needs to be corrected ESX and ESXi, they built insoftware intiators so you don't have a hardware initiator need - but if you choose to use a material to ensure that it is in the HCL - http://www.vmware.com/resources/compatibility/search.php

  This document will give you information on the how and why of using SAN storage - http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_iscsi_san_cfg.pdf
