• 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.

• question of vMotion iSCSI and jumbo frames

  Hello

  I have a cluster ESXi 4.1 using vCenter and a SAN MD3200i.  I'll do an upgrade to optimize the installation, which includes the installation of four NIC ports in hosts that will be used for iSCSI.  I struggle to enable frames or not, but if I do, I just want to do for the iSCSI, at least for now.  Currently, the maps iSCSI network on the hosts and the MD3200 iSCSI connections are connected to two switches separated, although I have seven other switches in the building connected to the PC, printers, etc.  What I only turn frames on two switches that iSCSI is connected, or do I have to enable frames on all my switches?  There is a Dell 2724 and eight 6224Ps of Dell.  ISCSI is connected to the 2724 and one from the 6224Ps.

  The two switches that are connected to the iSCSI ports are not dedicated iSCSI switches; they have other devices on them, but I can only enable the frames extended globally on the switch.  Would there be any problem allowing the frames extended on the switches, otherwise all connected devices are configured for them?

  Another question about vMotion: I will create four ports on each host for iSCSI vmkernel.  Currently, there is also a port configuration vmkernel for traffic management and vMotion.  Is it possible to set up each of the four iSCSI for vMotion vmkernel channels, or should I leave it configured on the port of vmkernel management?

  Thank you!

  Sure. If you're going to enable Jumbo frames, you need to have dedicated switches for that, or a switch that may have different units MTU on their ports.

• Questions about iSCSI and subnets

  IM planning on a deployment of 8 ESX servers connected to an array of iSCSI on double dedicated switches.

  1. 2 cards on each ESX host network is dedicated to iSCSI and VMware dependent ontraffic.
  2. SAN iSCSI target consists of two controllers with 2 uplinks of iscsi on each controller (4 total)
  3. The manufacturer of SAN is suggesting setting up of their SAN ports in separate subnets for higher throughput
  • For the sake of simplicity lets say assign 10.10.100.1 24 ports SAN 1 & 3 and 10.10.200.1 24-port SAN 2 & 4
  • On the side of ESX, a single iSCSI VMKernel address will be 10.10.100.2 and the other will be 10.10.200.2.

  My questions:

  1. do I have to enable trunking VLAN on the side of the switch so that the initiator 10.10.100.2 ESX failover to the port of SAN 10.10.200.1 and vice versa, because they are not in the same subnet and therefore not in the same VLAN?
  2. If this is the case, will trunking VLAN also solve the problem if we were to buy an identical iSCSI SAN on the road and 2 subnets more setup for controllers, but still only have two cards on the ESX Server.
  3. I would assign the 2nd ESX Server in this config with the same IP addresses as the first, or I re them with differnet IPs (but obviously still in the same subnet as the storage arrays), for example ESX 1 is 10.10.100.2 and ESX 2 would be 10.10.100.3

  Any other associated iSCSI I get with VMware, simply not able to think through this particular obsticle and I don't have the equipment to test it yet. Doesn't help that it's late in my part of the world and my brain power is depleting fast!

  Thank you!

  I mean really isolated network. No routing between them.

  Is the software of multiple paths that can pass a path to another, and if you need one network to another.

  Note that the PowerVault will have an interface of a mosquito net and to one another for each processor.

• sVMotion between iscsi and fc?

  I would like to know if sVMotion worked between iscsi and fc storage.  Just by looking at the possibility of moving from FC to iscsi on the road and wanted to check, it is that we give a host at the same time we can use svmotion to get the virtual machine out of a store on a datastore iscsi and FC database.

  Ideally the VM perform during this process. Any witch hunt, it's if it was running?

  Storage VMotion does not care SAN type, I carried out all types of migration between FC, iSCSI and NFS myself.

  So don't worry about it. But beware this SVMotion create large extra i/o load, so run when it will not affect the services running.

• How to compare premises, iSCSI and storage NFS for VMware ESXi 5 with IO Analyzer?

  Hello

  I have 2 hosts ESXi 5.0 with a few virtual machines running. I would compare the IO throughput for my local storage, iSCSI and NFS vmware storage store. Can someone point me to the right direction? I read the documents and tutorials, but I'm not sure how to compare tests from these 3 options.

  I have a need to compare the following storage options.

  Local disk on the ESX host

  iSCSI on QNAP NAS device

  iSCSI on EMC e 3100

  NFS on QNAP NAS device

  NFS on EMC e 3100

  IOmeter seems to be good tool based on reading, but still not clear where to make changes to pass tests of storage to another.

  Thanks in advance,

  Sam

  If you use IO monitor, then you must simply vmotion the VMS to the data store for the device you want to test, and then run the test (and Records results).  Can vmotion for the following data store and repeat.

• iSCSI and Fibre Channel on the Dell PowerVault MD3000 SAN shaerd with 2 physical servers

  Hi all

  I'm doing new virtualization technologies work in my office for assistance:

  2 x Dell PowerEDGE 2950 III each installed with iSCSI next accessing the SAN controller

  1 x Dell PowerVault MD3000 (10 x 300 GB 15 k rpm SAS)

  The

  VMWare ESXi is installed in an internal USB to load 4 x virtual machines which is

  under SOLARIS (using project, houses, SAMBA file server and)

  Source code repository and compile the source code of the project Build

  Server too.)

  5 x Windows Server 2003 which perform as Apache Tomcat application server.

  And

  I wonder if it has performance benefits in the application of the

  Shared SAN for these two physical server via iSCSI in contrast with

  Fiber Channel.

  I am aware that CF is faster and more expensive, but in this case, I won t run a VM with DB server on it.

  must

  I enter the path to have iSCSI or stick with the given FC

  the SAN runs on 15 k rpm SAS used by 2 ESXi server.

  Please let us know of a reflection regarding this configuration.

  Thank you

  Usually, you take NIC 1 gb connections available on your host and configure them as such.

  2 network cards go to the San, most of the time that it is actually two networks with different subnets.

  1 network card next LAN

  1 network card for the management

  We only use three network cards currently on our guests, 2 for San and the other for management and lan. We use two switches dedicated to dedicated networks dual iSCSI san. This allows to easily add additional hosts in the future.

  You get to decide a bit, but the double san network is pretty much a given. You can do all this of course with the VLANs as well. We use the switches unmanaged yet in our Organization.

  PS: Passing path recommended is to have completely isolated storage of the LAN network / network of the user.

• Connections Fibre and SCSI SAN/DAS directly to VM (RDM)

  We currently have an implementation of the 3 very generic host to ESX 4 where all virtual machines using vmdk disk or drives mapped to the external storage.  We are looking in the update to ESXi 4.1 and potentially you virtualize two of our primary file servers, however these boxes connect to several storage units SCSI and fibre volumes.   These volumes are 4 TB and more.  For example, a server connects to 2 x 4 TB volumes by fiber (spent) and 2x2TB via SCSI DAS.  Server B connects to the volume of 1 x 4TB through fiber and 1 x 4TB volume via SCSI DAS

  I'm trying to get a handle on storage that connect directly to the VM, but not to find a resource that speaks directly (at least that I am able to decern in speed reading).   My understanding is that RDM or NPIV fibre are possible methods.   NPIV seems to be out of reach, as the switch must be a mode NPIV which excludes standard SAN usage (i.e. I must have a dedicated switch just for NPIV.)  In addition, Brocade switches seem to only are NPIV supported if they are entirely stored (i.e. the E300 must have 24 active ports... it's expensive to say the least).

  RDM seems to require a total appropriation of the connector.  that is, I have one HBA per hectolitre VM.  On a host ESX I virtualize the server A and B, then have 1 VMFS volume via a fiber connection, I have 4 single port / 2 dual port HBA and 3 channels for SCSI.

  Basically, I think I know there is no way to use a single HBA or card SCSI to connect multiple external storage to various VM direct is just not possible (i.e. as NAT is network, NPIV is the closet in fiber and nothing available for SCSI).

  iSCSI is a solution, but I have currently no iSCSI storage nor the funds to migrate the current storage in such an environment.  Have also some concerns about the performance of iSCSI... but I think it's especially of ignorance of technology than of reality.  I looked at a few fibers to iSCSI (e.g. sandbox 6140) routers, but these seem very inefficient the costs as well.

  I have all options here, or is physical remaning with these solutions server my best option for now?

  With RDM, you could have the present LUNS for the HBA WWD from this phase you can add it only to the VM particual. So, it's like multiple LUNS, one of THEM and a lot of VM. so he would feed your needs.

• Important update 3.5 to 4 and new SAN

  Hi all!

  I am planning a major upgrade and would like to your comments...

  Current situation:

  4 - ESX 3.5 servers (HP DL380 G5)

  1 physics VC 2.5

  1 HP MSA Fibre Channel SAN

  You need to upgrade to:

  6 - vSphere servers (2 new HP DL380 G6, 4 HP DL380 G5 power)

  1 - Vrtualized Virtual Center (DB should also be moved to a new server of DB)

  1 - HP SAN Lefthand iSCSI

  Decommissioning:

  Former physical VC

  SAN Fiber Channel HP

  Im looking forward to this upgrade and I'm just curious on your thoughts of the process to do so.

  I see so many different ways to do this IDK what way to go with him. The new G6 servers will not have the attachments to the current SAN MSA so I want to be able to vmotion just more I'll also have to do a storage vmotion. With our 4 current servers we can take one down for maint. without impact on performance so that could add a way to make things too.

  Thank you!

  You need to keep your current online VMware license server until the updates are complete. Once it is done, and all hosts are on ESX 4 u1 and pulled into the new vCenter configuration 4 u1, you will be able to retire from this server. I'd keep around (offline) just for awhile to CYA.

  Once you have the first host with v4 u1 on it and attached to the fibre and iSCSI LUN, you can create the new vCenter Server VM and VM DB and start the process of vMotion. It's probably a good idea to put the two hosts (new) in the configuration immediately so that you can use those to run the virtual machine because they are vMotioned/migrated and updated day/updated to run on the new configuration.

  I would also use profiles on host computers to facilitate reproduce it exactly the same configuration on each of them. If there isn't an urgent need with only a handful of servers, it's something to keep in mind. It will make changing settings the same on all hosts later much easier if you are familiar with the process.

  For licenses on new hosts, you will have one for the vcenter Server, and another that covers the hosts. Here, no more license server you just enter the key and apply it to the hosts.

  I feel that once you get in it, it will be less confusing/bad you may think it will be.

  If you are more comfortable getting confirmation of the process before you start, reaching out to VMware (your sales representative is a good start) or a VMware partner in your area (one of the big boys, as a partner if possible). We used one at my last job, and I was able to bounce things off of them. Of course, it helped them already, and some paid on time left in the thread that we could use. Or suite at one of the moments where they were spot on.

• Network configuration for ISCSI and VMotion

  Hello

  I have an ESX host configured with the iSCSI storage and am currently working on the best way to affect my NIC I a four VMK vSwitch and two nic

  I also have an additional switch for VMotion.

  vmnic6 and vmnic7 are both on the San.

  After adding the new VMkernel and activation of vmotion, I was wondering why this has not shown as an additional path to the storage (I want to know if this is another question). Then I ran "esxcli swiscsi nic list d vmhba33" and of course, only the first four VMK was listed.

  Why the new VMKernel is not automatically linked to vmhba33?

  It would be a bad idea?

  See you soon

  Just to play devil's advocate, why shouldn't be VMotion and SAN traffic on the same link though?

  the iSCSI traffic MUST have a low latency and no mistake.

  VMotion can create advanced that could generate problems in iSCSI traffic.

  No idea why it does not automatically bind well?

  Can you vmkping each IPs Eql?

  You have to add each interface vmkernel of initiator iSCSI, with a command like this?

  esxcli swiscsi nic add - n vmk0 d vmhba34

• iSCSI and cable

  Hi all

  I have 3 physical server each with esxi4 and storage shared (win2008-storage box) with 4 gib nic

  I think to connect to each server with a crossover cable for storage and the use of iSCSI Protocol to map drives.

  I read somewhere that crossover is not supported and it slows down the performance.

  Does anyone have more information or experience about it please?

  Thanks in advance

  Hi Cariparo,

  Of course, you can do, see following diagram is what I use now.

  a direct connection to the SAN in the ESXi servers with nothing in the Middle, it can eliminate the single point of failure caused by the switch and also to provide redundancy.

  each color in the iSCSI network is another IP subnet by itself. the ESXi in the production network, I put two cable connected to two different ports and then add the bears in same vSwitch for failover

  hope this helps,

  all comemnts and input would be greatly appreciated.

  Kind regards

• iSCSI and LAN traffic even vSwitch?

  Hello

  It is a question for laboratory and not the production. I have a server with two network adapters.

  Is it possible to use these network adapters with two vswitch for LAN and iSCSI. Will it work?

  I know that it is not recommended.

  Thank you

  Edy

  You could also put them on a single switch with the consolidation of NETWORK cards. For iSCSi, you can have active NIC1 and NIC two mode standby. For data traffic, you can have active NIC2 and NIC1 mode standby.

• Cannot add to the inventory if virtual machine running on the other guests - iSCSI and VMFS5

  5.5 ESXi hosts free standalone version

  iSCSI mounts with multiple paths - relatively new unit with more modern hardware

  CHAP not used

  I'm running a few hosts in order to climb the same iSCSI data stores. The iSCSI LUN is visible and editable by all hosts. If Host1 is to map the iSCSI LUN (VMFS5) and a VM is powered, Host2 can add that VM to the inventory. It's possible with NFS iSCSI for a reason any. This is for a specific reason? Only when I turned off the virtual computer can I add it to both hosts. Other that just lock files are placed in the directory, I missed something related to the lock?

  From now on, adding new esxi hosts does not allow me to add existing virtual machine, less than the voltage first. Once again, NFS does, iSCSI, this isn't. Any ideas?

  It is not specific to ISCSI but rather to the use of VMFS. NFS has no awareness VM VMFS is and why it is not possible to do that with iSCSI / VMFS. There is a lock on the disk for each virtual machine of (race), and that's why the second host is not able to add this host to its inventory. With vSphere HA, this lock is released when a failover should occur.
