Maximum number of hosts mapped to a single LUN ESX

I have a TB 1.9 LUN presented to an IBM SVC to several groups of ESX/ESXi include versions 3.5 (ESX), 4.1 (ESXi) and 5.0 (ESXi).  I read 3.5 has a host LUN '' recommended '' limit 32.

I'm looking for more details on this issue.  This applies only the number of 3.5 hosts who can see the data store or all combined ESX hosts.  And why is it recommended to vs a strict limit?  We are trying to implement a logic unit number mapped to ESX host clusters as possible in order to support a mass migration to a new environment.

I'm pretty new to VMWare world so please excuse me if I'm not clear on what I ask, or do not include any other relevant information.

I don't think it's a contradiction at all.

It is said that a given host can have up to 256 LUNS.  A volume given (VMFS) are accessible by up to 64 hosts.

They are 2 completely different scenarios.

  • What is the maximum number of hosts supported by vDS

    Guys,

    I called vmware for max and min document and found only one 64 hosts of vDS supports, and only 16 vds is allow in a vcenter but not satisfied with these figures. Can someone let me know the supported maximum numbers associated with it. Thank you very much.

    Best regards, AB

  • Maximum number of virtual disk for a virtual machine in vSphere 4.1

    I read the maximum record rate and see that the maximum number of virtual disk is 16 for FT.

    I have the same document I seem not to be able to see the number max of virtual disk that can be taken in charge for a virtual machine.

    The number will be the same as the number of LUNS per host which is 256?  I know the max is for the host, but that be will come the number of Director to the total number of virtual disk that can be supported in the virtual machine?

    In fact, in a logic unit number, we can have more than one data store that can be mapped to a virtual disk.

    I'm confused.

    Thank you and have a nice week,

    Anthony.

    If I am not mistaken, you can attach up to 60 virtual disks to a virtual machine. 15 for each of the 4 virtual SCSI controllers.

  • What is the maximum number of carrots that I can attribute to a RHEL guest?

    What is the maximum number of carrots that I can attribute to a RHEL guest? We have a data center by telling us that they can not affect more than 4 cores in the guest OS, even if the guest OS is reliever of suposto the entire physical host (IE, it's the only host on the ESX node).

    We have 16 cores on the physical machine, and they tell us, that we can not have more than 4 in total in a single instance of comments.

    4vCPU per guest is max

  • maximum number of entries in "characteristics of writing."

    What is the maximum number of channels in the "write data"? It seems that it is only 16 entries. I have more than 16 parameters in my application. What do you suggest me? I would like to have all of the data collected in a single file.

    The Multiplex module allows to combine several strings into one. In general, use the parameter "by block. The output will be a single thread with all multiplex channels in the block. You can have a maximum of 16:1 multiplexed. Use several Multiplex modules. They do not have to be symmetrical, but do not keep track of how many channels is multiplexed on a single thread.

    In the writing module, click the box to the format Options file (ASCII or DASYLab) - at the bottom of the dialog box, you configure so that it matches how you multiplexes - by block or by value (for example). And then, on the right, set the number of channels is multiplexed in each of the input channels.

    Do this way said DASYLab disabling multiplex the data in the file. You will lose the channel names. You can configure the names of channel for multiplexed channels using the chains. At the bottom of the dialog box, you can assign a global chain for each channel. Tedious, but it can be done.

  • Maximum number of imported Ldap users

    Hello, do someone knows if there is a maximum number of ldap users that I can import for users of the NSA 3600?

    If you talk to auth method change LDAP-Local user and have your username using their powers LDAP to authenticate the SonicWALL, so it's 300 users.  If you configure SINGLE sign-on, then you can have 500 con-current authenticated users.

    This information is based on equity 6.1 installed firmware. If you have installed 6.2 these numbers are slightly larger.

  • Signature custom for the maximum number of connections

    Hi, is there a signature to check the maximum number of connection to a host attacker to open a port to the victim? or should I make a costom for this signature?

    Hello

    You certainly can do it on the IP addresses, follow these steps in making a signature Atomic-ip looking for a tcp packet with only the SYN flag set on port 443 to the destination. You would then add a number of events for the number of connections you need. According to the site however this will flood the channel alarm with alerts, because traffic going out etc it will trigger. Of course, this can also be problematic with NAT.

    I don't know one of the guys ASA on these forums could give an answer better than me with regard to the configuration of the SAA.

    I understand they'RE a dynamic IP filtering or something that can be used to do this, although I've never configured myself.

    Thank you

  • Cisco 881 - maximum number of VPN tunnels allowed?

    Hello

    I know it sounds simple and easy question, but I can't find the answer anywhere - so here it is: -.

    I need to know the maximum number of vpn tunnels that can manage a Cisco 881.

    (In the context, we have a group of users who work from home and office, so their laptops have the cisco vpn client, I need to know how much of these vpn connections the 881 can manage both before, he died a death)

    Host-, I read somewhere a line that State maximum number of users is 20 but believe it was referring to a VOIP service.

    Thanks in advance.

    The 881 supports 20-tunnel IPSec:

  • Is there a maximum number of MeV?

    Is there a maximum number of MeV, you can have in a database?

    I had + 400 TEUS of databases and performance issues experienced with DML that would normally fine on a single schema database.

    I am wanting to know if I can scale up to + 12,000 TEUS.

    It could be a database of 11 GR 2 or possibly 12 c.

    There is no limit on the number of policies MEV in a database. This number does not necessarily mean the system performance, which depends on how many active cursors access VPD protected tables, are the complexity of these predicates VPD and are of course the complexity of queries. You have that many people want to examine the AWR report and capture the SQL and its related VPD predicate for the top SQLs.

  • What is the maximum number of photos I can stack them in a group?

    On Windows 10, second gen Core i7 with 24 GB of RAM using Lightroom 6.1.1.   Trying to stack a little more than 1000 pictures.  Lightroom not responding initially, then seems to have completed the task, then according to the use of Task Manager ~ 16% (4 hyper threaded cores) CPU, 2, 3 GB of RAM not used, no hard disk activity.  This last for hours if I let is sit (watch a movie).  Out of Lightroom, it disappears and continues to consume CPU until I have killed him.  Go back to the top of Lightroom and no tails do occur.  Tried this several times.  Tested with an own catalog as well.

    There is no issue about a maximum number of pictures that can be stacked in a single stack.

  • Maximum number of virtual machines by free ESXi hypervisor?

    Community of VMware,

    I just installed the free 5.5 ESXi hypervisor and I wonder if the same virtual machine limits apply to the stand-alone scenario as vCenter? Can I run actually 512 VMs? What, if any, is the maximum number of virtual machines, I can run on a free version of ESXi?

    From 5.5 ESXi limits most have been removed, but only a limit of 8 vCPU per VM remains. So if I'm wrong, the VM 512 mentioned for each host (see http://www.vmware.com/pdf/vsphere5/r55/vsphere-55-configuration-maximums.pdf) affect the free hypervisor.

  • Reached the maximum number of pluggable databases

    Hello

    I seem to have a problem creating a pluggable database.  I'm getting ORA-65010: maximum number of pluggable databases created.  What seems strange to me, is that I have only a plug-in database in the container.  This doesn't seem to be a common theoretical problem? maximum number is 252.? I've seen a few different numbers while rummaging through the internet.  I can't seem to find documentation about this limit or why that would trigger my max at 1.  I wonder if this can a hardware limitation, but after going through the error logs and love it, I can't find any problems with the initial installation.

    A little info, installation was complete installation + CBD + PDB.  Class Server, standard installation and I can connect both the container and the snap-in internal database and connection to the outside.  Most of the time I think its configured correctly.  I have a feeling that I missed something along the way, but I'm struggling to find an explanation for this.  The documentation is fine as a response, just needing a point in the right direction.

    Thank you.

    Hello

    For Enterprise edition of Oracle database, the limit is 252 connectable to databases. If you are using an Oracle database Standard edition, you can create a single snap-in database.
