• Problem with Direct-attached storage

  Hello

  I have a Dell PE 2900 with a MD1000 attached by the PERC 6/E.  I'm currently adding the MD1000 storage which is RAID 6.  In the vSphere Client, it indicates the ability of the device as 4.72 TB.  However, when I walk through the add storage Wizard, he told me that only 739,99 GB is available?  This table is new and it has just been initialized.  There is no data, or the partitions on this subject.

  Does anyone have any idea why it won't let me use all storage?

  Thanks in advance.

  Hello

  Actually, 2TBs - 512 bytes. That 512 bytes is very important to consider.

• Options for sharing local storage

  I work with a test environment and familiarize myself with some of the more advanced options of VMWare.

  Currently, in our lab, I have a server that has a ton of direct-attached storage. We have a San were included in the budget by the end of this year, but in the meantime, I would like to use this server as a substitute of SAN.

  I'm looking for the cleaner way to do this under ESXi 5, preferably without spending any extra money. We have licenses for the VSA, but it seems that I can't use VSA without several servers in a cluster - which I did not. Is there a way to take advantage of VSA without creating a cluster VSA?

  Is there a way do this within VMWare infrastructure that does not involve using something like FreeNAS or a similar solution, which will eventually create giant VMDK files that I have to deal with? I mean, I could lift a virtual server with a huge VMDK attached and ask one of the software solutions to give me iSCSI targets, but it seems hardly elegant. I might just install FreeNAS on bare metal server, but then I lose the use of the VMS host server.

  Forgive me if this is basic - I did some research first. I am looking for a way to use the data store (s) on this machine for other servers who lack storage space.

  Edit - not sure I understand the question / Setup... If the server that has a ton of local storage is already running ESXi?

  "I'm looking for a way to use the data store (s) on this machine for other servers that don't have storage space" "

  With the exception of the magic and mirrors behind VSA, ESXi does not have the ability to share a local data store. This data store must live somewhere else and be introduced to several machines in the way of an NFS share, target iSCSI or FC LUNS.

  I was in that same boat a year ago--a company hired me on for a large project of VMware without realizing that the shared storage is the key to an installation of VMware. They ordered servers with cargoes of physical local storage. Oops. Finally convinced a SAN is the only way (this is also before the release of v5, therefore not VSA). We have since removed all disks, and have most of them redeployed elsewhere (a dedup backup on a physical computer).

• HP585 direct attached mirroring of the issue table

  Hi, am new to the forum so forgive me if I am committed any misstep

  We have two servers HP DL585 (amd opteron) with Direct-attached storage bays (attached via a scsi cable), we want to create an environment from virtual machines using ESX 3.5 (this is whats available us - packed) we have also all vmware tools put at our disposal, but no other budget to spend on of NAS\SAN

  Is there a way to create a mirror between the two machines (and tables so to speak) for failover is possible if we're going down or something similar - I think that HP storageworks storage mirroring for this, but nothing to VMware build to do the job?

  We will install the version of ESX on the disks (mirrored) hard local and the slices VM on the array (raid 5)

  You can check with HP. It may be possible to use the MSA70 in any of these two DL585. You may need a few extra bits of a license, but?

• MSA 2040 Direct attached iSCSI

  We implement a VSphere environment 5.5-3 hosts directly connected to an MSA 2040 with iSCSI.  Attached host to the MSA a question directly or have us use switches?  Our equipment provider said

  "in order for the volumes of VMWare to have access through shared storage needs through a switch. You can run questions where if they are directly attached, then the VMDK on the single host may not be seen or accessible on other hosts (high availability or Vmotion). »

  Also

  "Support from direct attach to the msa via iSCSI is dependent on the BONE."  Some OS support other don't. MSA does not directly connect to Vmware via iSCSI. "

  I talked to HP directly and they claim to direct connection via iSCSI is supported with the MSA 2040 and VMware.

  Is anyone running this configuration that can put my mind at ease?

  Thank you.

  Hello

  Yes, you can use a directly attached MSA 2040.

  I use this configuration yourself by using DAC 10 GB cables, also sold this solution to customers.

  Please note that each host must have 2 connections to the San (if the SAN has two controllers). Each host must have a connection to each controller on the SAN.

  4 directly attached hosts is supported (the controllers have 4 ports on each one).

  Please note that several subnets must be used and configured to allow a correct path discovery. A BIG note to stress also is DO NOT USE the PORT iSCSI MAPPING!

  Be sure to activate the Robin. Please note that you will see an active path perform I/O by the data store (since only one controller has a volume), but in case of rupture of the cable, or controller failure, there are switched to the other controller.

  I use this setup for a few years and I love it!

• Storage on iSCSI - mounted directly from the VMware virtual disks

  I am setting up a HUB/CASE/box Server mailbox of all-in-one for fewer than 500 users on a Windows 2008 R2 virtual machine and am about to configure the storage I need. The two words that I can't wait to hear more from Microsoft PSS is "not recommended" or "not supported." I have a Dell Equalogic PS6000 and have the ability to 'direct attached' compared to the VMware virtual disks for storage of mailbox databases. We run vSphere with vMotion, etc..

  Using virtual disks bad practice? Advantages or disadvantages I should know about? Adding a layer of complexity that might come back to bite me?

  I have a very similar setup and am currently using directly attached iSCSI volumes EqualLogic berries for my Exchange 2007 mailbox stores.  I also have the role of running UNIFIED messaging that works in fact remarkably well even if everything is running on a virtual machine.

  It was in large part because the EqualLogic recommendations had to use directly attached volumes so that taking snapshots multi-application/replication tools worked correctly.  If the Exchange mailboxes are held on a VMFS volume, then Tools EqualLogic will not be able to get to them.

  Microsoft have been OK on this configuration, and I actually had them made up our VM, one or two times when we iron out some problems of UNIFIED messaging (although I hide icon "VMWare Tools"!).

  The best thing to do would be to create volumes you think you'll need and attach them directly to the virtual machine using the Microsoft iSCSI initiator, and then run the Exchange tool (I forgot his name) to test the storage for speed and capacity.

  See you soon.

• Connect FI two directly attach FCoE storage and SAN switches

  Nobody tells me if I can connect FI two directly attach FCoE and SAN storage switches also, as you can see in the diagram of connected network?

  If so, should I FC Switch function Mode? Any concerns should I consider?

  Or the best solution would be appreciated. Thanks in advance.

  The UCS will be in Switch Mode FC, which means that it has a default area.  We cannot make a Zone merge with Brocade because we have no control to set up specific items such as domain and other articles CF IDS that need to be changed when you connect a Cisco FC switch to a Brocade.

  Usually in this situation with a 5 k or a MDS you might be placed in mode of interoperability, which changes the default settings and we will talk to them together - in this case, you can't change these settings, so the only supported configuration is CF Cisco at Cisco.

  See you soon,.

• VMware and EMC 5300 Direct attached

  VMWare 5.0 using EMCVNX5300 direct attached SAN.

  I want to install Windows 2008 Virtual Macines that will host the video surveillance system.  Archiving requirements video call flat for up to 10 TB of storage from the video files.

  My question is how best to configure the LUNS on SAN VMFS or RDM?  With VMFS, I would have to introduce several 2 TB LUN and through the Windows Disk Manager to extend the volume.  If I use RDM am still limited to 2 TB virtual disk file?

  I want to keep the simplified system, but I have to take into account the needs of e/s for video archiving for up to 150 HD cameras.

  Welceom to the community = with vsphere 5, you can submit more than 2 TB LUN actually up to 64 TB - so I would use RDMs with 10 TB raw LUNS to the virtual machines - note, you will still need a VMFS data store to house the VMDK file pointer that will redirect the r/w on raw LUNS

• iSCSI as shared media storage?

  I was wondering if anyone had here a few thoughts about the use of iSCSI as shared media storage.

  I would use it via ethernet to my ready nas pro with two Gbit connections is associated with a single IP address.

  I know the obvious limitations in bandwidth by ethernet and the risk of data corruption when sharing, but I only use the same media on one PC at a time, so I guess that's not much more of a problem.

  Further recommendations on the idea of shared storage would be muc appreciated also.

  Thank you. :)

  Ulf

  iSCSI is ideal for this workflow. There are faster options now that are affordable compared to the Gbit and iSCSI units which have expansion slots supporting 10 Gbit Ethernet. Cards Intel 10 Gbps Ethernet are $380 for a single port cards and the Thecus 8 and the 16bay units take over some of the Intel 10 GB cards. NETGEAR has 10 Gbit Ethernet switches for $900. If this isn't an option now then 2port NAS/SAN unit will be fine. Don't expect much more then 75 to 100 Mbps even with load balancing. 10 Gbps also reduce access latency. Gbit will be a delay if try to change directly from shared storage.

• Configuration of MXL port for PS-M4110 storage array

  Dear all,

  I have to configure my Force10 MXL GbE 10/40 for PS-M4110 storage array. I have two PS-M4110 connected to ports 0/13 and 0/15. I have configured the following way.

  FTOS (conf) # don't activate any dcb

  FTOS (conf) # enable iscsi

   

  Configuring the ports 0/13 and 0/15 (ditto)

  OTF (conf-if-you-0/15) con #sho

  FlowControl rx tx off
  spanning tree bpmh edge-port
  spanning tree rstp edge port
  spanning tree portfast 0
  spanning tree pvst edge-port
  Profile-compellent iSCSI

  I just need to know if these settings are correct. And what I have to configure iscsi target (3 260 860) ip address of the port-(A.B.C.D) as well? If Yes, then what IP should be given here? Group-IPaddress?

  I used this guide as a reference.

  And it seems that you have everything in place. The guide recommends not to use iscsi optimization for large san deployments. You can browse the guide too, just to double check.

• Set up new network iSCSI for VCenter

  Originally when we configure our environment VSphere, that we could not have our network engineers set up a separate subnet for iSCSI traffic.  Now, I have this ability and plan configuration.  I will be using our maintenance window to make this change instead of driving through the sectoral approach.

  My questions are about what communication is necessary between the two subnets, if necessary.  I will bind to the vmk ESXi iSCSI on the new subnet and they are the separate vSwitches but I'm not clear if the two networks require that any communication on the VCenter server.  The management network and LAN traffic will remain where it is in my plan will and so one of the network adapters on each host ESXi. Our network engineers want the two subnets to be completely separated, because this new iSCSI subnet will speak also to our recovery for SAN replication site, which brings me to another question. in order to use the software EqualLogic Auto - SnapShot Manager\VMWare Edition, she wants to be able to talk to the iSCSI network and the VCenter.  Anyone here used this feature without SRM?  I'm not planning to allow the SRM software currently in production, only half of my servers are VMs where all are as in DR and slightly different configs, so until I can duplicate both slots and fully use SRM I'll wait.

  I am also having a different subnet created only for devices management and applications such as updates of HQ of EqualLogic SAN, head of group and the servers, devices, etc.  It would be a more ideal situation to move the VCenter for?

  FYI, VSphere 4.1, ESXi 4.1, EquaLogic PS6000

  Also, I use FT and VMotion on different VLAN internal to the production of LAN and those will not change.

  Any idea or clarification is appreciated, I would like some feedback before .

  Welcome to the community - there is no need for vCenter communicate to your iSCSI subnet - all communication is handled by the ESX/ESXi hosts if ther EqualLogic can't answer to and his need to connect to vCenter.

• 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).

• Satellite M100 - driver for the mass storage controller

  Help, please. I don't get the hat of message I have no driver for my mass storage controller. I downloaded and re-downloaded the drivers of Toshiba. Microsoft found nothing.
  It seems to be bus PCI 5, device 6, function 2.

  Can anyone help (in terms laymans terms please). It drives me crazy.

  Thank you

  Hi Tellgio,

  What Toshiba drivers you have reinstalled exactly? I'm pretty sure that you don't have installed all the drivers because you always have a yellow exclamation point in Device Manager
  In addition, it would be interesting to know what operating system is installed

  I also had a yellow exclamation on mass storage controller and in my case it was a missing card reader driver. If you need to install this driver on Toshiba official site:
