• Cisco UCS Direct Attached ISCSI Storage access upstream to storage array

  I'm doing my first installation of UCS with a chassis 5108) and (4) B200 M3 blade and (2) 6248 fabric interconnects. The plan is to connect our EMC VNX directly on the fabric of interconnections as the chassis will be the only system for access to the SAN, after migration from our current system. The fabric interconnects will be transmitted to (2) 4500-X switches configured in a vs.

  In my research of best practices and general deployment guidelines I noticed the need to create (2) separate iscsi VLANS for fabric and a fabric in B. I'm guessing that this requirement is the lack of STP as YEW is configured in EHM, but I was not able to find an exact answer. Any idea would be appreciated.

  My main question and my concern is that if I create a second VLAN ISCSI on our X 4500 and then create both of these VIRTUAL on FI networks A & B I'll be able to connect the SAN to the UCS as well as our former VMware cluster (we are migrating our system HP Compute and storage UCS 5.5 environment) in order to facilitate the vMotions of storage?

  If I understand your question: can a host attached to 4500 (connected to the UCS FI), access LUNS on the VNX, which is directly connected to the UCS fabric interconnect through lanes (EHM FI) material? YES! I would accept this for a migration, but not forever, because it means that traffic on the fabric of interconnection.

• subnet VMkernel iSCSI for direct-attached storage

  Hello

  I have two hosts esxi 6.0 that I connect to a shared via iSCSI storage. I followed this document technical http://www.vmware.com/files/pdf/techpaper/vmware-multipathing-configuration-software-iSCSI-port-binding.pdf#sthash.7bztDoAS.dpf to configure interfaces iSCSI on the esxi with binding ports host. No problem.

  I use HP MSA 2040 with a dual controller and I'll connect two hosts directly on the shared storage. As for the hardware, according to the documents on best practices, it is recommended to follow a vertical subneting for ports of controllers. However, I have not found no requirement for iSCSI ports in vmware, all of the examples I found configure each vmkernel port in a different subnet, as I did:

  vSwitch0

  iSCSI1 - vmk2 - 192.168.1.11 (unused vmk3)

  iSCSI2 - vmk3 - 192.168.2.11 (unused vmk2)

  So, my question is vmkernel ports are in different subnets? or could they be in the same subnet with no difference performance wise?

  Any help would be appreciated.

  Thank you!

  in your case, because you are trying to achieve Multipathing to iSCSI Software initiator, the vmkernel ports should be in the same subnet.

• Migrate MD1000 from direct attach to a MD3000i

  I currently have a MD1000 direct attached to a PowerEdge 2950 with a PERC 5/E. I wonder if the MD1000 can me moved to a MD3000i and keep the existing virtual drive and data intact?

  
  

• 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

• 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?

• Home environment, direct attached eSATA or iSCSI/NFS 1 single?

  Greetings...

  Today, I am running ESXi 3.5u4 on my server at home, plans to move to ESXi 4.0 in a few months.  Right now, I'm flying without a net - no disk redundancy.  The server is not the space of the slot to add a good RAID card (it's a Shuttle XPC), I'm looking to go with an external RAID device.  I am considering a device that got both eSATA and 1GbE onboard (QNAP TS - 439 Pro).  If I go with it as a NAS, I'll plug 1 port of the NAS directly to a port 1GbE dedicated on the server, run frames, etc., leaving the 2nd port on the NAS connected to the management network.

  I run 5 VMs full-time, no not particular disc, i/o intensive, other than the file server that my wife and I use, and it's only a little time.  If I SIN instead of direct connection, I see a noticeable loss of performance?  If this isn't the case, should I be looking at iSCSI or NFS?

  So that I do not see a big performance hit, I'd rather go NAS, so he would give me a little extra flexibility to connect to other systems for the time machine backups, etc.  I'm leaning towards NFS, since iSCSI, if I remember involves stuffing a SCSI inside TCP frame, no. generals, creating news?

  The differences in performance between NFS and iSCSI would be minimal on a smaller device. Extended frames may also be minimum value, but your tests that prove. NFS is much simpler to install and use. Is there a lot of contention for disk access then you will start having performance problems. There is not a lot of processor or controller in these devices and no drive of caching (secure disk cache).

• How to clean and do a fresh install with attached iscsi LUN?

  I intend to migrate both esx 4.1 with esxi5.1 hosts before you wipe and do a clean install.  Each host is connected to two iscis without, with 4 LUNS of each SAN attached to each host.  Each lun
  spread over 3 degrees is. I plan on vmotion (not storage vmotion) guests from one host to another to make the upgrade.  I'm stuck on the determination of what will happen to the iSCSI LUNS after I
  upgrade to esxi5.1 guests.  It seems that I should just be able to reattach, but I'm not sure.  Can I just attach the LUNS to the new installation 5.1 hosts and see all the
  VMDK intact, or is there something that I am on?

  And should the migrated to another host virtual machine continues to run on the iscsi san, while I upgrade of the host, they were released since then?  It seems that storage must be removed from the process as the LUNS
  should not remain attached to the host after it is cleared and the iqn name no longer exists.

  
  Am that I on the right track here?  What Miss me?

  jackjack2, understand you this? I went ahead and moved to esxi 5.0 U2 of ESX 3.5 u5. Had to perform clean install and I have an iSCSI SAN. That's what I did:

  1 a taken a screenshot from all my ESX host configurations. Go to configuration-> software adapter-> click on the iSCSI--> properties--> iqn copy map and alias-> click the dynamic discovery tab and note any IP address. You may need these IPs with the discovery of data warehouses later.

  2. after having documented the configs, put the host in maintenance mode.

  3. after maintenance, remove the host from the vcenter server. Connect directly to the host and close.

  4. remove all the network cables. Cable marking help before you detach the cables.

  5. clean install esxi 5.0.

  6. after installation, before rebooting, set the network cables.

  7. configure and test the management network. If your network management test fails, see if you have anything that is entered in the id vlan. Chances are that your port is not shared resources in the physical switch. In this case, remove the id vlan (during the configuration management network) work.

  8 bring the vcenter server host.

  9 configure the network, dns, time, etc.

  10 Add a software iSCSI adapter. This card will have a new iqn. Either you provide this iqn to your SAN administrator so that it can update side SAN, or you can use the old iqn name.

  11. in my case, I made a copy of the new iqn and then deleted. Entered the old iqn name obtained in step 1. Additionally, entered the alias (since one was present before). After that, a new analysis and update still does not fill in data warehouses. So, I went to the properties of the iSCSI adapter and then discovered added tab dynamic addresses IP that did not exist before (otherwise, you will need to enter the virtual IP address of the cluster that you data store (s) belong to). Once the IP addresses have been added to the dynamic discovery tab, he asked if I wanted to rescan the HBAs. I said yes and viola! my data stores have been populated.

  12 Add the host to the cluster.

  Note that you can add iSCSI adapter when you affiliate you the host to the cluster. However, in this case HA will not be happy because no heartbeat of data storages will be detected. In addition, when data warehouses are discovered it may appear initially as not mounted. Don't panic. After a minute or two it will be mounted.

  I hope this helps!

• Fully connecting directly attached data warehouses in a cluster of ESXi?

  I have deployed two identical 5.1 ESXi hosts (servers Dell PowerEdge r720xd) each to 5,46 with storage to direct connection. They are both currently enrolled in our vCenter Server 5.1 and participate in a HA cluster. Their respective databases are also members of a group of data store.

  Each host is connected to its own data store, but not the other host data store. This effectively disables most of the HA/DTS features, and connection status of host for each data store is marked with a warning for missing connections. We have desire of VM migration and load balancing between the two hosts and the warehouses of data to be as homogeneous and transparent as possible.

  My question is simple: what is the most practical and effective way to establish the necessary connections to reach a State fully connected to hosts and data warehouses?

  Hello

  in this case you need something like a virtual appliance that uses your local storage to make it a shared storage. Your hosts can then access the storage via iSCSI/NFS. At the end of the day, you will have the space of a single node left (CT ~ 5.46), because the device (s) will reflect your data for more security against failure of the host.

  The easiest way would probably be the vSphere Storage Appliance

  But there are also other solutions as a virtual of DataCore and HP StoreVirtual VSA facility.

• 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.

• 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.

• LUN cannot be added without formatting

  Hello

  Details:

  2 x ESXi 4.1 HOST (HP DL380G7)

  1 x HP MSA2012fc

  The MSA are directly attached to a FC HBA on each server.

  I have two LUNS on the MSA (1 TB = LUN_0, LUN_1 = 1.6 to)

  The two HOSTS of ESXi 4.1, I have access to these two LUNS.

  My problem:

  I have updated the first HOST to ESXi 5.0.

  After the installation, I have two data store in the Configuration. Local data store and the LUN_0 data store.

  I jumped on the storage card and made a new analysis. On the FC HBA, I could see three courses:

  1 attachment

  2 LUN_0

  3 LUN_1

  I jumped to the storage and also press Rescan. Nothing happens.

  I press Add storage. ESXi 5.0 shows me my LUN_1 and I click Next.

  Now seems to me that I have to reformat the LUN. I can choose something else.

  I can't do this! On my LUN_1 are my productive VM.

  Does anyone have a solution for me?

  Beste wishes

  Martin

  Your solution could be as simple as the LUNS need to be mounted on the other hosts.

  In one or more of the hosts do not show the LUN and type of PuTTY

  esxcfg-volume - l, lists usable LUNS that are NOT mounted, if no LUN is displayed it means that all your LUNS were mounted.

  If you see LUNS listed in the above command, type this to mount each one LUN at a time

  esxcfg-volume - m "vmfs_label_name", the name of lable must be the friendly name you gave the LUN when initially formatted.

  I had this same problem with one of my ESXi hosts and this took care of it without formatting.

  It may be useful
