• question of iSCSI san

  Hello everyone,

  I just created my first with software e open iscsi san solution.

  My situation: on the local disk, I put my VM

  I created 4 iscsi data warehouses

  1 will be used to back up my VM and can be reached for Vsphere

  The other 3 serve as a backup for my 3 VMS solution. I am connected to them through the Iscsi initiator in the virtual machine, format them, and now they appear as an additional drive in the virtual machine. I can see them in Vsphere but is no longer in data warehouses, but in devices (because they are formatted as NTFS)

  Now the question:

  Is it possible to see what data is on data warehouses that are formatted to ntfs When you are not connected to the virtual computer?

  When a virtual machine should crash, backupped data should always be saved to disk iscsi, but where can I get it?

  Thanks in advance, onkt

  NTFS is only accessible via windows server only. You can mount the iSCSI drive backup on another virtual computer.

• solution for ESX iSCSI SAN

  Hello.

  We are looking into getting a SAN iSCSI for ESX.

  On readers, y at - there a big difference between sata and sas and sas 10K vs 15K?

  How iSCSI performance are compared to the SAN fiber?

  Can you guys recommend an iSCSI solution right?

  Excerpt from Dell PS4000 and it seems to be a good product.

  (On players, is there a big difference between sata and sas and sas 10K vs 15K?)

  Yes, 15 k SAS are faster and a bit more expensive, but worth it!

  (How iSCSI performance are compared to the fiber SAN?)

  ISCSI SAN is not as fast as the fiber, but compared to the local drive is a big improvement for your applications, users, etc.

  (You guys can recommend a good iSCSI solution?)

  Personally, I think Dell equallogic are great! PS600XV is what I put in place.

• 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.

  Kind regards

• iSCSI SAN, blocking the ability to attach a RDM to two VM?

  Hello

  We have an iSCSI SAN and I wanted to test with clusters on this stuff, but I can't get a RDM attached to more than one virtual computer at a time.

  I know that MSCS is not taken in charge by iSCSI, but is not supported or is it not possible to join a ROW over a virtual computer at a time?

  Thank you!

  Kenneth

  The solution should work... so with RDM, but also with an initiator of software inside each node of the virtual computer.

  If you use RDM, you must configure the SCSI controller in physical mode.

  On the second node does not add a new drive... but easy to use existing RDM disk (or disable ROW filtering of the customer).

• Promise VTrak M310i iSCSI SAN

  RE: Promise VTrak M310i iSCSI SAN

  This unit is located in the 3.5 but a solution to budget.  Someone there had positive results with this SAN and ESX3.5i?

  The M310i has 2 x 1 Gigabit NIC.  We expect 30 VM on the device hosting and their running on the network of private storage.  Two gigabit NIC will provide enough flow to run the number of virtual machines?  Connection to Dell 2900 series 3.

  M310i product page

  Thank you in advance...

  It is really difficult to give a definitive answer one way or another how this will work.  The real answer is that it depends on what are these virtual machines.  If you use just 30 virtual machines that run background services, do a lot of disk i/o, etc., then you're probably fine.  If you use more than a couple of servers to database or by e-mail on these boxes and consider storing discs on which these virtual machines on this device, 2 GigE interfaces may be too limited for this environment.

• Looking for a SAN solution

  We have a small infrastructure we use for software development purposes. We have 4 ESX servers, all currently running ESX 3.5 u3 and about 30 mV. We store the virtual machines on the local storage of ESX. We want to move to a centralized storage for virtual machines and that we want to use VMotion and HA. Is there a low-cost SAN solution for a facility like ours?

  A Dell MD3000i would be a good choice for a 4 ESX server environment, very cheap compared to blown full SAN solutions (even the stuff Equalogic Dell is at least 5 times the cost). We use them for small customer installs (internally, we use Dell |) (EMC Clariion CX3 and 4, but they would be an exaggeration). Make sure you budget for a couple of decent network for iSCSI switches to (we use Cisco those but those are probably fine if you want to buy everything from a seller to relieve the problems of Dell support)

• OPENFILER w / ISCSI?  Any decline in performance compared to a commercial ISCSI SAN?

  Experiment with VMWare ESXi and want to put in place a San to store all Virtual Machines and storage.  Are there performance problems if you use OPENFILER compared to a commercial ISCSI SAN?   HCL hardware supported - Asisde speed problems are there?  I intend to use the hardware failover and load balancing, but need a San to achieve this.  On a budget, so I was wondering if all this aside, will be an OPENFILER solution be slower than a commercial SAN ISCSI...

  Well, maybe...

  I agree with this, if you use the other stuff on the same machine as Openfiler, but if you have dedicated a machine serving via Openfiler iSCSI volumes, then you should get pretty good performance - perhaps even comparable to "material" iSCSI implementations  I have a PE2800 with a single processor and 4 GB of RAM which is my Openfiler iSCSI SAN/NAS head.  The performance is very good - is perhaps not as good as some of the commercial solutions, but works very well.

  In addition, many commercial solutions are focused on software, hardware not in function.  The short week, SOHO are "firmware" based, but iSCSI is still usually done in software - many times by a demon of Linux on the box.  Of course, it's the only thing he does, but simply because it's a software does not mean that it will hurt.

  I use Openfiler in a production environment - no problem.  You can also purchase support for Openfiler, which makes it even more viable production.  Do not hit, just because it is a software, just because it's open source, or just because it's Linux.  There are a lot of people out there using Microsoft Windows Storage Server in production - why not Openfiler?

• virtual san solutions (VSA): what is the current state of the field?

  As of many SMEs, we feel the pressure from DAS and get on some sort of SAN.  We are planning an implementation of iSCSI SAN, which will probably (at least partially) kind of VSA to take advantage of our DAS ability in the new iSCSI environment.

  What are the main actors in the field of the VSA?  My Google search has turned up:

  the storage facility for vsphere (not crazy about the use of low disk space)

  FalconStor

  StarWind vsa

  Device HP LeftHand VSAN

  In addition, we consider OpenFiler/FreeNas...but it is not clear to me if he can really operate in VSAN mode (e.g. RAID between hosts, etc.)

  Are there others that we should consider?

  Works all stand as a clear leader for a reason any (price/functionality/usability/reliability)?

  Performance there data?

  Thank you.

  I just wanted to add a small clarification around the vSphere Storage Appliance. Yes, it start with a requirement of RAID10 on each host, but this was relaxed in early 2012, while it supports now also two configurations of RAID5 RAID6 & - http://blogs.vmware.com/vsphere/2012/01/raid10-requirement-for-vsphere-storage-appliance-vsa-relaxed.html

  The point here is we do not want a failure of the single PIN to bring down a node in the cluster.

  Just in case this is the reason why you expected the vSphere Storage Appliance.

• 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"...

• ESXi 4.1 or ESXi 5.0 with iSCSI SAN

  Hello

  I'm trying to establishing an environment that is / will be an iSCSI SAN backend entirely.  I know of a lot of reading that the best practice is to config the ESXi host with:

  VMKernel > vmnic > physical network adapter > switch ports > port on SAN (config 1:1 - no grouping of vmnic)

  Environment:

  ESXi 4.1 & 5.0

  Force10 switches

  EqualLogic iSCSI SAN (PS4000 & 6000)

  Here's my real question (playing the Devil's advocate):

  Why I shouldn't team 3-4 vnmics on a vswitch with multiple vmkernel ports?

  Given my environment.  Can someone point me to a technical document that explains what will / could happen if I set up the environment ESXi in this way?

  Thank you

  So, basically, we want the SAN to take full responsibility for the failover instead of the network and/or the SAN for who should resolve the failure (which could lead to the time of restitutio in integrum longer session).   I understand that correctly?

  Yes, that's right, we want to stack storage for vSphere manage with path selection and tipping - and by connecting each vmknic directly to the physical vmnic map we sort of "simulate" how to CF cards and also ignores the network failover mechanisms. As you probably know you also need to "bind" the iSCSI Software to the two vmnic (GUI now in 5.0, esxcli in 4.x)

• is it possible to have 2 iscsi san?

  Hi all

  is it possible to have 2 iscsi san?

  Thanks for any comments, you can add...

  Hello.

  Yes, but it is better to keep them separate connections on separate switches/VMkernel as well.

  Good luck!

• ProLiant BL460c G7 iSCSI SAN boot

  Hello
  I'm looking to start a single ProLiant BL460c G7 of our HDS iSCSI SAN and then install ESXi 5. The blade has no local storage. The SAN is already in use by the cluster of our production.  In the iSCSI SAN config guide it States to set up storage so your host has access LUNS. How can you do this if your host is not installed? How can I configure the LUN to only be accesed by my hosts IQN name when I don't have an IQN name yet? What I must first install ESXi? I'm obviously missing something any help would be great!

  This is true, for this, but as your correctly point out if the OS is not installed how do you have a software iSCSI initiator - boot from an iSCSI SAN is supported only if you have an initiator of independent hardware installed in your ESXi host.

• 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.

• iSCSI SAN storage

  Hello

  I am trying to build a practice for VCP certification test lab.  I use Workstation 7.1.4 and ESXi installed on the same host.  Can anyone recommend a good 'free' iSCSI SAN storage virtual appliance?  I went through the market, but wanted to get a recommendation from experts.

  Thank you

  Kim

  There are various products that you can use. E.g. Openfiler, Starwind, open-e or VSA from HP. For the last HP offers especially for VMware Player/workstation demo version.
