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.

  • What is the field replace it for?

    Generally, the value overrides what not.  they were once as necessary to manage the chapter plays, but not because there isn't "chapter playlists." And if you don't know what you're doing, they can get you into trouble.

    A substitution changes the end action that would occur without the substitution. For example, if a timeline has an end action to go to the 2 timeline and the button that calls if a substitution in the 'main menu', using this button to call the timeline will result in the timline ending and in the main menu.

    The "chronology of the hand" is a property only for the drive, and the default seems to be so he could be on the first timeline added to the project.

  • Hi, after updating to Firefox v 10.0 I can no longer open Web sites by entering the address in the address bar. The site looks ok because it works in the Solution Explorer, what's the problem?

    I get the adresse_web in the toolbar, but Firefox does nothing, it just locks. It only opens Web sites when I choose one of the Favorites.

    This problem may be caused by an extension (possibly AVG Safe Search) which does not work properly.

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

  • Cannot create .vswp file to Virtual SAN: CPP to DOM returned Out of Memory

    Hey all,.

    In my virtual home existing SAN lab, I meet an interesting problem. When I try to turn some of my virtual machines now use the VSAN, vCenter present with the following error, even if the data store is online and running virtual machine workload. Restart the server vCenter (not on the virtual SAN) has no impact on the problem. I have also noticed I can't reconfigure the virtual machines as well and cannot vMotion; the operation times out. It's all the same problem.

    My next step was going to try to restart the hosts, but I wanted to see if anyone else experienced this or if there was a method to establish the first case before nuking the question, since, if it were production would take us actually a failure. All virtual machines running on the vsanDatastore are fine and all the capabilities of storage and tickboxes are green in the web client. I wonder if there may be a memory leak or something else. Uptime for these hosts is 55 days, running on the beta update VSAN. Thank you all!

    I restarted all hosts today and they all started right up. Will do the upgrade code of GA and see if the problem repeats. Thank you all!

  • The field naming convention?

    What is the rule when it comes to naming of fields?

    I've been name as follows: "TFLastName' TF for text field, then what is the field.

    Is it really necessary for me to start the field in this way?

    No, it isn't, but it is advisable that when you read code you can tell what type of object is simply by looking at the name.

  • Remove the virtual SAN HP P4000 VSA

    Hello

    We have 2 Dell poweredge 2950 host running vpshere 4.0 and we have virtualized internal storage of these Dell using P4000 VSA happening as a virtual machine on each host. Our virual servers use this storage.

    Recently, we introduced NetApp FAS2020 on our network and we move all the virtual servers for the netapp.

    My question is "what is the best way to remove theP4000 VSA Vsphere? (I don't want leave no trace). We don't have support with HP and could not find much information on the web.

    These are just virtual machines that use the local VMFS storage on servers, so to get rid of them first to power them off.  Then right-click on them and choose "Delete from Disk.  This will permanently delete.

  • What is the best solution for this idea...

    I have a task I'm trying to test and understand what would be the best solution for this, any recommendations would be appreciated.

    Devices at your fingertips:

    -2 ESXi hosts

    -1 iSCSI SAN OpenFiler (new just installed the app)

    2 ESXi hosts run a small amount of virtual machines that are all in the same domain.  I want to have a file server (or a repository somewhere) that houses a folder with easily accessible software (OS, Office, etc.) on the field.

    According to me, that if I made a virtual machine with a large hard drive and share the software, this would not be the best way because it would be dependent on the OS.  Someone has talked about doing a separte VMDK for it and then install it on the operating system on the virtual machine. This way I could always remove the and mount it somewhere else.

    It seems a bit weird to me that the software within this "shared folder" will also be sitting on the data store (if I create a virtual machine and need to use the OS/etc).  Not that doubles the space for the same software (in the comments, then the data store)?

    What is the best approach to make this action which can be accessed at the prompt (mostly windows) in the field?

    What is the best way to stay away the software doubles in action and on the data store?

    Please forgive me if I put interpereted your question.

    The problem you seem to face is that you must mount the ISOs of VMS software and physical systems that are on the field.

    (please, correct me if I'm wrong on this)

    If this is the case, then the best way to do would be to create sharing NFS on the openfiler, if you use openfiler to main databases also then he would be better for sharing this was separated to prevent the other help to be able to tamper with the VMDK and VMX files for your virtual machines.

    This could then be mounted in ESX to access the ISOs. While being easy to install on Linux and Windows machines to access the ISOs.

    If you have questions about NFS mounting in windows, so, this link may help

    http://sagehacks.WordPress.com/2009/01/21/HOWTO-mount-NFS-shares-under-Windows-7

    If you are needing to access the VMs software and it is mainly the downloading ISOs then th ISO directly to the data store is possible.

    This allows you to use ESX to mount the ISO on the virtual machine.

    On the point that the software will use double disk space when you install the software on a machine virtual car will be on the network share and the VMDK virtual machines in the data store. That's right, and that's by design.

    Each virtual machine under ESXI is 'independent' (http://www.vmware.com/virtualization/virtual-machine.html)

    This means that each virtual computer must have its own copy of the application.

    This perspective reflection of each virtual machine as a separate system of 'physical '. They interact with each other as if they were physical systems.

    Each VMDK resembles a physical hard disk. Being accessible (in most configurations) 1 VM at a time.

    So if you had a set of physical systems connected to a domain and I wanted to install an application on each one, then each would have its own local copy of the application. It's the same thing with virtual machines.

    However

    If you configure a set of physical machines so that you run the software from a network share. It is possible to do the same thing using virtual machines using the exactly the same configuration. However, the chiefs more associated to this are important in both cases.

This means that I am looking to update, but I am limited by the motherboard, because it doesn't support USB 3.0 PCI Express 3.0 and SATA III. Change the motherboard to a new one that supports these features would be the simple solution to this problem, but I heard stories of people unable to get fans, active on the evacuation and fire works after breaking out in a new motherboard. I also heard stories from people who have been able to get everything running smoothly after connection of the Control Commission, in a certain way.

  • What is a VPN solution that is more stable than IPSEC VPN? What is the latest version of VPN client recommended for Windows 7 & 8 users?

    Hello

    I would like to ask a few details & concerns on our existing VPN configuration.

    1. What is the Cisco VPN client recommended for users of Windows 7 and 8? Is there an official documentation for this Cisco? We currently use customer VPN Ciso 5.0.7.

    2. we are running IPSEC VPN with only 1 gateway & only local authentication (No ACS) for our client. Recently, we have some concerns that they are the VPN connection is down. Whereas if I'm the one connected to the VPN, my connection is stable. Is there any point that we must consider up in the network. Is there a better configuration or solution that we could recommend to the customer as SSL VPN?

    3. If you want to use SSL VPN anyconnect secure mobility & we want to implement redundancy on the FW, how will the license work?

    Thank you!

    An AnyConnect-based VPN is the replacement recommended for remote IPsec VPN access. (source)

    AnyConnect can use SSL or IPsec (IKEv2) for transport.

    For an ASA redundant firewalls (running 8.3 (1) or later) any permit required AnyConnect are shared between them. that is, you just buy licenses for a member of the HA pair. (source)

  • What is the advantage to affect multiple virtual machines in a data store?

    Hello

    Quite a question stupid and basic, but I can't answer . What is the advantage of having multiple virtual machines in a store of VMFS data instead of having each VM in another VMFS data store? (eg. 3 VMs in 1 data store or 3 data warehouses and each virtual machine in one of them). I can only think about the ease of management for storage administrator because it creates only a single large LUN.

    Thank you

    By allowing multiple virtual machines in a data store, you can run more than 256 virtual machines in a DRS cluster.

    As a host has a limit of 256 scsi identification numbers, which means that it accesses no more than 255 LUNS shared. 1 scsi ID is used for local storage.

    In a DRS cluster as each host must be mapped to the same data warehouses to ensure that virtual machines can be moved on the cluster and run on any of the hosts.

    Now in my life as an architect VMware PSO I saw that a lot of virtual machines that require a single data store. The main reason to isolate a virtual machine on a data store must provide sufficient i/o performance. This can be achieved with other solutions than to isolate a virtual machine on a data store. Having a properly architected storage subsystem is crucial, vSphere can get out of a very large number of the IOPS / s. With technologies such as SIOC and DRS for storage, you can check that the virtual machines receive IO performance according to the needs.
