High latency LDAP with ESXi 6

• vCenter and PSC HA 6 with high latency

  Hi guys,.

  We have about 10 locations with each a few hosts.

  3 those who are major hubs located in the regions of the North A., Europe and Asia.

  Currently, almost all sites have their own vCenter (5.x - 6).

  I would like to consolidate the vCenters but I read that the PSC is very sensitive in terms of latency.

  I guess that 100ms is the maximum, as well as for long-distance vMotion!

  Between our 3 centres, we have around 200-250 ms latency.

  Latency within a region is about 20-90ms.

  So now I'm not sure if it will work:

  Each hub would have 1 vCenter (or maybe 2 with cluster failover and Ext. SQL DB) manage all of their clusters within the region.

  Each hub would have 2 PSC devices, all in the same SSO domain and site.

  I was hoping to get the good reviews here on how you Landa who.

  Thanks in advance!

  You are there with your latency 100 ms between ssp max. BTW, max latency for long distance vMotion 150ms RTT. These are difficult technical limits, but are we comfortable support based on our own tests. Things would work technically with higher latencies? No doubt. But don't put yourself in a risky position which can prevent you from getting support if there is a problem.

  That said, that many large customers are now consolidated down to an area of SSO by region. It would be great if we could get down to a global domain SSO, but today in vSphere 6.0, we recommend that you really do not go more than 100ms. The longer latency between PSC, more the risk of conflicting changes in the SSO domain. In addition, with a view to performance of the user interface, if you manage multiple vCenters via the improved linked Mode, it will get slower and slower this latency increases.

  We certainly perceive your feedback from customers, and we would like to help our clients for their SSO domains the architect as they see fit. But today, we have guidelines, that we need to work within. I hope this helps!

• Extremely high latency during the migration of the local data store to data store shared.

  Hi guys I hope you help me. Sorry for my English btw, I'm not native.

  Let's start!

  I have:

  1 vCenter
  1 host
  1 Distributed Switch (with a pg for managing network/IPstorage the esxi)
  1 standard switch (empty)
  1 FreeNAS to provide iSCSI LUNS
  1 Microsoft to provide iSCSI LUNS

  When I try to migrate virtual machines between the warehouses of shared data or data shared at local store, all right. The problem has become when I try to migrate virtual machines from the local to the shared data store. All data stores down (all paths down) and back up and I get this error:

  "Error caused by the /vmfs/volumes/volumenID/VMDirectory/Disk.vmdk file.

  
  When I try to migrate virtual machines from the local to the FreeNAS iSCSI data store it fails immediately.
  When I do the same local Microsoft iSCSI datastore that it takes a time loooooong to migrate the virtual computer, give it to me even all the paths downwards and uplinks down error but not lacking in migration.

  I'll give you some screenshots to see the errors.

  Thank you very much!

  EDIT: I have extremely high latency notice when I try to migrate from the premises of warehouses of shared data. average 2000ms with peaks of 50,000 (see my response below for more information)

  Finally, I found the solution! The problem is that I have been using E1000E vmnic instead of vmxnet3. I have configured an adapter vmxnet3 and boom! 20 ms in all migration!

  Thank you to all for help, especially Nick_Andreev !

• HP 15 laptop: atheros wifi causes extremely high latency peaks

  Windows 10 has been the only OS I have used, so I can't speak for others... I noticed that (initially copying files via wifi lan has shown) using wifi really totrures my laptop... it's worse than if the CPU is 100% responsible...  I've updated either, but nothing helps... Tried 2 win10 distributions, but still have the problem:

  Wired LAN:

  

  WiFi LAN:

  

  Even when I am simply navigate using wifi I think it's a torture for the laptop... (and bluetooth it also causes)

  PS (the 2nd screenshot is taken when im close enough to the wifi router) if I get still the wifi router the situation is getting worse (the laptop is fully charged (100% red spikes) without reason...) The same phenomenon occurs with different routers

  (Even though the mouse pointer and the sound almost stop, offset)

• X 220 dpc high latency

  Hey,.

  I m very disappointed at my new X 220.

  I ve got dpc very high latency when I m using the built-in 82579LM adapter.

  Sound is stuttering in surfing, playing music.

  With the Wireless 6205, so good!

  What I tried:

  -New Windows install (Lenovo installation clean tutorial)

  -Most recent Intel driver for the network card

  -New Lenovo driver for the network card

  -The powermanager max performance value

  All drivers, BIOS, utilities (such as powermanager etc.) and windows are updated.

  Any suggestions?

  
  

• VCenter Server (standard) useful with ESXi is free?

  Trying to decide what, if anything, to actually buy VMware.  The free ESXi product license is... enough.  I would really like to central management, backup or read/write capabilities with rcli (piracy without installation - I think I said that correctly).

  My question is this.  There is a VERY big jump in $$$ of the products beforehand essentials range or better (I think that the Standard line is unnecessary).  I currently have 5 VMware servers (2 under Server Linux 2.0 on server newish hardware, each, 2 ESXi 4 server about 4 VM running on old jobs as each House a unique VM (due to higher disk IO) and ESXi 3.5 server running on 32-bit with 1 VM hardware).

  In any case - with a mixture of mission critical production VM and VM little criticism that don't necessary not to live on a San and puff SAN bandwidth, I'm not sure I want to limit myself to 3 physical machines.  It would be probably enough for the next 5 to 10 years, but it would affect my SAN strategies and I have to buy at least 1 or 2 new costly servers.

  So I thought that maybe just get the vCenter Server for centralized management would work.  I always have 2 or 3 more enjoyable new servers ESXi 4 on the San with mission critical servers, while continuing to have 2-3 of older machines with individual local readers VM (I like to keep virtual for purposes of disaster recovery for) running.

  I can't find any information on knowledge if it would work, and it would offer benefits etc..

  You cannot add free ESXi to vCenter. Adding a host requires the inside the host vCenter Agent license.

  Sorry about that.

• Problem of memory with esxi 4

  I have a brand new hp dl380 G6 with 2 xeon x 5560 server and 48 GB of ram ddr, it is used in combination with a fiber of msa 2212 hp san chanel.

  The host runs 36 windows virtual xp with each 1vcpu and 512 MB memory.

  given that we have upgraded to esxi 4 almost al my virtual machines are showing the alarm that the memory usage of comments is raw, some off them show same not the warning, but the symbol of the alarm.

  In the virtual machine overview comments mem % varies between 90% and 68%.

  The host mem is also high, always 537 MB.

  The same takes place of issue with the version of virtual machine 4 and 7, vmwaretools is upgraded to version latsest, even with a new installation of a host appaers problem.

  On the same host, we tested with esxi 3.5, we have not had any warning to all mem % comments has been between 2 and 18%

  the host here for most memory less than 100 MB

  Is that a question or there at - it something wrong with my setup?

  Has anyone seen this problem too?

• Advice of external storage for use with ESXi 3.5 (free)

  I'm under ESXi 3.5 (free) on a server with internal storage.  I would buy external storage and switch my VM to it.  The virtual machines that I have running on the server are not used very often, so I don't want to put a lot in it.  Can anyone recommend an external SAN/NAS storage device that would work with ESXi 3.5 (free)?  I'm looking for maybe 500 GB - 1 TB connected to the network via Ethernet.

  Less than the price of Iomega devices (the ~ $300 model) are sold to a group of work so not really high performance. If you find that this performance was not acceptable, you'd have no way to improve the system.

  I would like to use your existing NAS NFS features. If this does not work out, you can always go for something with more umph.

  If it is a lab test the Iomega should be fine. If it has an environment that can grow in size requirements and performance over time, you might want to try to build a more powerful Openfiler SAN/NAS.

  First try your existing infrastructure.

• Alignment of disc with ESXi

  Hello

  One of my colleagues spoke to strengthen certain storage performance by aligning vmfs with the underlying storage and higher vm disks. However, he sent me it describes some fdisking in the service console. It already looks like a hard thing to do, but my question is, how can align the disk with ESXi. There is no real service console and using the Tech mode is not really supported. Does anyone have experience with disc alignment in ESXi? Is it really necessary or will it help?

  TIA

  Timothy

  From ESX 3.0 drives are already alligened. So the ESX 3i

  disks (VMFS volumes) are already lined up. Make sure that your VM disk are

  aligned and you should be fine.

  Doc for sale listed by Troy should help you determine how to align the drive of the guest operating system. My advice would bring just the data disk not the OS.

• PowerEdge Raid700 in RD540 with ESXi Thinkserver

  Hello

  I'll put up a hypverisor 5.5 ESXi update 2 on a lenovo RD540. There is a RAID700 controller.

  I use 3 HARD drive in a RAID6 configured with the tool of the bios (Mega RAID LSI)

  The server works fine, but I don't see the healthy of the RAID on the ESXi.

  I don't see the virtual disk, not the adapter of storage or physical disks. If one lose a disc ESXi does not know, I hear only the PIF from the server.

  How can I solve this problem?

  If I use the "Lenovo easy start' to install ESXi RAID adapter will be with ESXi?

  Thank you in advance.

• Could not detect my DPS and hdd with Esxi 6.0

  Hello forum,.

  I bought a relatively new desktop for my studies of cisco computer. I am completely new to exsi and took notes on the net to install esxi.

  In "Select a disk to install or upgrade", I am unable to see the two hard drives.

  I have,

  CPU Intel I7 - 4790K, motherboard Asus Z97 - has

  240GB Kingston SSD

  Toshiba 1 TB HARD drive

  I tried to format the two hard drive using windows 7 and tried to install Esxi 6, but the two remains undetected.

  I tried 5.5 as well but the result is the same.

  Help, please.

  Thank you.

  ESXi is built for server hardware, he may simply not support your disk controller. Since it is a lab environment, you can check if VMware experience before: how to make your unsupported work SATA AHCI Controller with ESXi 5.5 and 6.0 helps build a custom installation image that runs on your hardware.

• LDAP with ssl

  Hello Experts,

  I just tried to set up a LDAP authentication with the built-in feature of the apex.

  Because I wasn't able to make it work, I tried to set up my own LDAP authentication scheme with the following code:

  create or replace package body "PKG_AUTH" is
  function FUNCTION_LDAP_1( P_PASSWORD IN VARCHAR2, P_USERNAME IN VARCHAR2 ) return BOOLEAN
  
  as
       p_dn varchar2(128) := 'cn=' || p_username || ',ou=XX,ou=YY,ou=ZZ,o=data';
       p_ldap_host varchar2(128) := 'ServerHostName';
       p_ldap_port number := <PORT>;
       l_retval pls_integer;
       l_retval2 pls_integer;
       l_session dbms_ldap.session;
  begin
    l_retval := -1;
       dbms_ldap.use_exception := TRUE;
       begin
           l_session := dbms_ldap.init( p_ldap_host, p_ldap_port );                -- Seems to work fine if i comment the next two lines. So I think the I'm able to contact the LDAP server.   
           l_retval := dbms_ldap.simple_bind_s( l_session, p_dn, p_password );    -- if I execut this line, I get the error: "ORA-31202: DBMS_LDAP: LDAP-Client-/Server-Fehler: Can't contact LDAP server"
           l_retval2 := dbms_ldap.unbind_s( l_session );
           return true;
           exception when others then
                 l_retval2 := dbms_ldap.unbind_s( l_session );
                 APEX_DEBUG_MESSAGE.ENABLE_DEBUG_MESSAGES(p_level => 3);
                 APEX_DEBUG_MESSAGE.LOG_MESSAGE(
                     p_message => 'l_retval: ' || l_retval || dbms_utility.format_error_stack|| ' <|> ' || dbms_utility.format_error_backtrace,
                     p_level => 1 );
           return false;
      end;
      exception when others then
      return false;
  end FUNCTION_LDAP_1;
  
  end "PKG_AUTH";
  
  
  
  

  I get an error ' LDAP-Client/Server-Fehler: failed to contact the LDAP server.

  To me, it seems that the problem is in the line (please look at the comment in the code above too)

  l_retval := dbms_ldap.simple_bind_s( l_session, p_dn, p_password );
  
  
  
  

  Additional information:

  • We have defined a All-Open-Rule to our ACL.
  • On the front end, I get a Message "Invalid Credientials" (or something similar)
  • Request Express 4.2.3.00.08
  • I can connect to the LDAP with the code in the following thrad: Ping in PL SQL function
    That's a reason more to my guess that I don't have a problem "cannot contact the LDAP server."

  • I'm confused (due to this error)

  • I think that we have not implemented a portfolio for our LDAP server. Do I really need?
    On APEX_LDAP , they say, you need just a portfolio if you use "SSL with one-way authentication" (APEX_LDAP. AUTHENTICATE = > parameter:p_use_ssl)
    But now the problem seems to have originated elsewhere. I I'm wrong?

  Appreciate any help!

  Ok. Use build you - in ldap auth. schme?

  No. I still cannot do its job. I can connect using the following code:

  declare
     l_ldapHost VARCHAR2(100) := 'your.ad.domain';
     l_ldapPort NUMBER := 636; -- set your SSL port
     walletPassword VARCHAR2(30) := 'wallet_password';
  
     l_retval      pls_integer;
     l_session     dbms_ldap.session;
  
  begin
        l_retval                := -1;
  
        dbms_ldap.use_exception := TRUE;
  
        l_session := dbms_ldap.init(l_ldapHost, l_ldapPort);
  
        l_retval := dbms_ldap.open_ssl (l_session, 'file:/etc/oracle/wallets', walletPassword, 2);
  
        l_retval := DBMS_LDAP.simple_bind_s(l_session, :p_username, :p_password);
  
        dbms_output.put_line(l_retval);
  DBMS_LDAP.UNBIND_S(l_session);
  end;
  

  You can use custom authentication.

  But you must install the portfolio and add your domain root certificate to trusted certificates. And don't forget to change l_ldapHost, l_ldapPort, walletPassword, p_username, p_password to your values.

  But why offer apex to a system of authorisation: built-in ldap where you can use ssl, and on the other hand they do not offer an opportunity to set a path to a portfolio of oracle?

  Do we not have to install the portfolio to a special directory? (If we want to use the built-in schema auth). ?

  See the documentation for APEX 2.4 managing settings for Instance to see how to install portfolio pending of the APEX.

• Having problems with ESXi/vSphere Client Network

  First of all, I apologize if it's thread is in the wrong section.

  I recently installed ESXi v6.0.0 in VMware Workstation 12.0 trying to familiarize myself with ESXi as I recently graduated and I forgot most of what I learned from the class I took.

  Then, ESXi installed smoothly and was very painless.

  Then, I tried to create a virtual machine. It's when things are messy. I can't understand why, but I don't get any network connectivity after obtaining a DHCP address to all within the virtual machine, in addition to being able to ping the host ESXi itself.

  First of all, networking is like so:

  10.10.10.1 router/gateway

  10.10.10.254 DHCP, DNS, server, VMware Workstation files 12

  10.10.10.250 ESXi host

  10.10.10.244 ESXi reviews - Windows 7

  Googles DNS 8.8.8.8

  VMware workstation 12:

  AMD FX-8350

  ESXi host

  Images: 2015-10-04_21-13 - 57.png, 2015-10-04_21-14 - 34.png

  The vSwitch has the following properties:

  Image: 2015-10-04_21-19 - 38.png

  
  

  And the following then occurs on the ESXi prompt:

  Images:,2015-10-04_21-01 - 58.png, 2015-10-04_21-03 - 32.png

  
  

  I can't really understand what the problem is, or what is happening. Yes, I could set up an internal network of the virtual machine with a firewall and what not, but I was hoping that there would already network connectivity while I wouldn't do. Also, is it possible to make attachments online?

  
  

  Thanks for all their help

• Can I use 6 Converter Standalone with ESXi 5.5?

  Hello

  We are running ESXi 5.5 and wishes to conduct P2V.

  Just would like to ask you if we can use "Standalone Converter 6" or we should use "Standalone converter 5.x?

  Thank you

  Yes. Converter 6.0 is backward compatible with ESXi 5.0, 5.1 and 5.5.
