• the storage SAN boot configuration

  I replaces my VMware host and have a question about best practices to configure local storage. Currently I have three Dell servers with embedded vmware 4.1. My new host has 4 300 GB SAS 15 k drives. I am currently begin directly to an EMC SAN using iSCSI. My plan is to continue to start directly on a new EMC e 3300 SAN using iSCSI. What is the best way to use local storage?

  1 create a Raid 5, but only use it for the installation of vmware?

  2. create a smaller Raid for VMware, then another for the space to use the?

  3 another option all together?

  Thanks in advance for your help,

  Don

  If you install your ESXi on that RAID group, the difference will be available in a local data store.

• request help to validate the SAN/network configuration

  Hello, I am a new Member of the Forum, but I have worked with ESX for awhile and I do as much reading/study that I can.

  I'll put up a new SAN HP MSA 2012i and 2 guests VMware Enterprise to use the San.

  SAN block size is 64, and I know configure vmdk in VC/VIC, which should make the VMs' offset 64 and therefore correctly align the VMs. 99% Windows Server VM.

  Our SAN has 2 controllers and disks configured as 1 vdisk that will be divided into multiple LUNS.

  management by controller 1 port

  2 ports for iSCSI on each controller.

  All are assigned static IP to the bosom of our subnet 172.16.0.xxx so they can all talk to the HP Procurve 2824 switch and therefore the hosts to be may eventually connect to the iSCSI LUN.

  My questions:

  1 should I configure VLAN on the switch of the management controller ports Ethernet iSCSI SAN?

  2 within the ESX, for his vSwitches, for the Service Console and vKernel, I use different subnets? (for example 172.16.1.xxx for the Service Console and 172.16.2.xxxx to vKernel, etc..) ??

  Or I have to put the vSwitches in the same subnet 172.16.0.xxx?

  3. I know that I create the LUN in the MSA web console and then I point Virtual Center and hosts see LUNS. Can someone refer me to anything that can explain this in more detail?

  Thank you!!

  As they say fast, good and cheap, pick two. It's just a fact of the business. We often work with the material we have and do the best we can.

  Go with 3 VLAN

  1 for the management of virtual machines and any other non-virtuelle 172.16.0.0/24. Use 2 of your network adapters ESX hosts so that it has resume function.

  2 storage VLAN 1 172.16.1.0/24 1 Teddy

  3 storage VLAN 2 172.16.2.0/24 1 Teddy

  This configuration enables redundancy for storage and networks VM/SC, with the hardware you already have.

  You can still develop the latter if you get the funds.

• SAN storage configuration recommendations

  We have a HP SAN with two fiber switches and a Bay of storage MSA2012FC with 12 146 GB drives.  I am trying to decide how to configure storage for our VI3 environment and seeks recommendations.

  At this point, I am considering two-Bay RAID 10 (6-146GB disks each) with 1 (220 GB) or 2 (440 GB) LUNS defined by the RAID array.  The virtual machines are configured in an HA configuration so I think it would be better to have two tables separated raid against one.  This way I can separate the pairs HA between the RAID arrays.  If I create a single RAID 10 array, then if more then one disk fails in this table we could lose everything.  In the future, we will add another MSA2000 pregnant then we will have another 12 146 GB drives.  At this point, we can expand each Bay RAID 10 to 12 146 GB drives to give us more storage space and performance.

  This sounds like a good plan?  Any advice would be appreciated.

  Hello

  RAID 5 is recommended because the table can stay together if 1 disk breaks down. With spare disks, this is a good configuration. RAID 10, a disk fails and you are switched. If this also works...

  I like Raid 5 and I have set up my disk space based on execution of 10-12 VMs per LUN. Who is the the average number per LUN. It's all about redundancy.

• Virtual loan SAN - recommended Configurations vs HCL

  I'm on version 1.1 of the document, it shows a R280 Dell that is not on the HCL VSAN and it includes SuperMicro which is not on the HCL.  It doesn't have the Dell R720, the R720xd and the T620 appearing in the HCL.  How to solve these two?

  Correct,

  Duncan - Thanks for the reply.   I was concerned by some servers which have been listed in one place, not both.

  Wade spoke last week and he strives to address this problem in a reasonable amount of time, it is indeed not ideal.

• Creating hidden snapshots?

  Hello

  My eq is PS6210E model 70-0425. A cluster of hyper-v (4 guests) connects via iSCSI.

  The SAN, I configured 4 instant and for replacement if necessary.

  However, I see a lot more snapshots for each volume this empty space volume... and I see that are requested by the hyper-v via the VSS hardware provider hosts. So, I opened the Auto Snapshot Manager on each host, but there is NO timetable. I also took a quick glance in the Task Scheduler... but no jobs are configured.

  Where can I look to find this snapshot planning 'ghost '?

  Thank you.

  Hello

  An application calls the Volume Shadow Service. (VSS).  Are you running the DPM?   VEEAM?  ASM allows you to create a snapshot, he put a comment in the description of the snapshot, are there comments on these snapshots 'ghost '?

  Kind regards

• Could not open a file to VMDK using SAN transport using Netbackup 7.1 "you don't have access rights to this file.

  Hello

  I'm trying to backup VMware clients using Netbackup for VMWare 7.1 using the type of transfer to san, and the forum NBU told me that my vm-admin user has no right of access to the VMDK file. However, I checked and I can download the backup host VMDK files and take and remove snapshots as vm-admin user.

  The servers are configured as follows:

  vc01 is a Win2008R2 vSphere 5.1 Server

  ENC1-bl09 by enc1-bl12 are blades running ESXi 5.1

  VM-bak01 is a Win2008R2 NBU media server 7.1 server and is defined in NBU as backup VMWare host

  Data warehouses that contain the VMDK files for the guests are all about EMC and HDS storage accessible via the San by the NBU Media Server and ESXi servers (although mapped through different areas)

  ESXi servers have access to local data and NFS storage warehouses too, but none of these warehouses are used by clients.

  I could save a few guests we via NDB, but they finish in time because the network is not fast enough. Estimated time of 8 days for nightly backup!

  So I have to use a SAN to back up the guests, but he keeps fails with the error below...

• Starting VMware SAN

  I understand the notion of BFS, but how do you get the image on the San to start with? Can anyone tell me the best resource for SAN boot configuration.

  Harold,

  SAN boot is very easy. Ensure first that you have UCS connected to a fabric of fibre with support NPIV is enabled. Next, configure a policy of startup boot-from-SAN (you WWPN SAN targets) within the UCSM. Then apply this policy to a Service profile who need to boot from SAN. Once this is done, retrieve the WWPN of the Service profile in question and have the SAN area admin you a big enough for your installation of NOS LUN. Once all this is done, connect your ISO AMENDMENTS to a KVM session and start service profile. If everything is correct, the AMENDMENTS will see the LUN target like a local disk and you can begin the installation.

  I hope this helps.

• Adding a user role for SAN switches

  I'll try to find the correct location in 3.3 ACS to add the following: roles = "network-admin". We have our SAN with Ganymede switches +. When one user other than admin connections, you get the role of "network operator". The Cisco MDS 9000 Family Troubleshooting Guide, version 3.x doc explains the role if you are using IOS/PIX Radius. Thank you.

  Hi Ed,

  Here is the link,

  http://www.Cisco.com/en/us/docs/storage/san_switches/MDS9000/SW/rel_2_x/San-OS/Configuration/Guide/cradtac.html

  If you are looking for:

  GANYMEDE + custom attributes can be set on a control access (ACS) server for various

  Services (for example, shell). The Cisco MDS 9000 family switches require custom GANYMEDE +.

  attribute of the shell of service to use for the definition of the roles.

  Cisco ACS GANYMEDE +.

  Shell: roles = "network-admin".

  Shell: roles * "network-admin".

  Cisco-av-pair * shell: roles = "network-admin".

  Cisco-av-pair * shell: roles * "network-admin".

  Cisco-av-pair = shell: roles * "network-admin".

  On GBA, if you go to: the Interface configuration, GANYMEDE + (Cisco IOS), check nex to: "display a window for each selected service in which you can enter custom GANYMEDE + attributes.

  Then, go to the configuration of groups and define the role information according to the above attributes.

  Hope that helps

  Kind regards

• Brocade SAN Content Pack Setup

  I imported the content pack Brocade SAN into our insight of 1.5 log device. The SAN admin configure the redirection of syslog server network to advise to the switches through the IP address and port 514.

  After more than 24 hours, no data appears preview newspaper under the Brocade SAN dashboards.

  Is there another step, I'm missing? The documentation is sparse on this product.

  I thought about restarting the insight journal unit, but a warning appears on the hosts not being able to continue logging after loss of connection with the device, so I wanted to do only if absolutely necessary.

  Thank you

  Would you believe said SAN admin typed in the wrong IP address of the insight journal device? problem solved. human error.

• SRM with two HP Lefthand P4500 Iscsi SAN

  I'm in the middle of SRM with two HP Lefthand P4500 and I have a few questions. I will award points to the answers.  I need to build the site of the DR at the main location because the MPLS between HQ and the Dominican Republic will not be ready for a month or two.  (1) can I build on Esxi hosts, DR SAN and configure SRM on the HQ site or should I wait for the SPLM is connected between the two sites? (2) the customer plans to use an MPLS of 10 Mbps between sites; is it a big enough to tip of VLAN stretched between sites? (3) what is the best far from approaching my situation?  Finally there is someone out there who has installed SRM between two HP LH the's 4500 that can give some advice?

  I have SRM with P4500 LH installation.
  It is quite simple and a good start would be books Mike Lavericks SRM, because they have step by step guides to configure the NHL P4500 with MRS.

  I use VLAN stretched if you can get it, because it will save a lot of hassle in the recovery of your infrastructure.

  If you have any questions you can DM me.

• Performance data store local vs fiber SAN disk IO

  I'm looking for a table of comparison of performance or other documents that will give me the change in the performance of the disk i/o for virtual machines that are hosted on local data warehouses vs fiber attached LUN.

  Does anyone know where I might be able to find this information?

  (HA, DRS and VMotion are not at stake here).

  Thank you.

  You won't find that.  There is NO way to give a comparison that you are comparing apples and screwdrivers, they are not the same family.

  SAN's storage shared, managed by a central unit full time on a fiber infrastructure.  But it depends on your switches fiber, HBA, your configuration, the disks in the SAN, the manufacturer of SAN, speed of the disks, the number of disks... It goes on and on.

  Each SAN / fiber / Configuration is very different.

  Local storage depends on the RAID configuration, manufacturer, your RAID card, disks... once again more info that can be included.  The line at the bottom is Local disk can be more responsive at times, but since you are limited to the number of disk (6 or 8) are limited to the performance, but the flow is the key.

  You will get a FLOW much more fiber than the local disk.  More load, less stress (since he is not relying on the local system to provide the resources AND the host operating system).

  SAS is better than SATA for the case of all VM on both systems.  so keep that in mind.  It is also very important to comparative analysis.  IOmeter will help you determine what is best for you.

• What are the requirements for the mode of transport san

  Hello

  I have a proxy physics vcb 1.5 (windows 2003 x 64), and I always use the command vcbmounter with san - m option.

  On the vcb proxy, I compile and run vixDiskSample on a disk to a virtual machine that is on the san lun, and I'm surprised that 'san' is not in the modes of transport listed.

  I don't have that:

  vixDiskSample-host vccenter-username username-password pass - vm "vmPath = / data center/vm/vm1 '-info ' [Storage1] vm1/vm1.vmdk.

  & gt;  Transport taken modes supported by vixDiskLib: file:nbdssl:nbd

  I installed this version: VMware-vix-disklib - 1.1.0 - 163495.i386.exe

  The virtual machine is power off.

  The SAN / HotAdd configuration you have for VCB should work without modification. Can send you the paper through a private message?
