• Best Senario distributed virtual machine between SAN LUNS and replication fail over Senario

  What the best best Senario for the installation of virtual machines on Big LUN or each VM on LUNS dedicated:

  We planninig to implement 70 virtual machines on Esx 3.5 servers with replication LUN usisng CA of HP 7.

  using 4 Big 800 GB data store on SAN RAID 5 Lun (each LUN will be contains 16 VMS)? or each VM will be deployed in separate small LUN 50 GB data store on SAN, RAID 5 and that this effect on the failure during the procedure on the DR Site if we choose BIG LUNs, also if this virtual machine includes 3 disks (store them on each disk on the different data store or the same data store)

  Thank you

  Remember that the virtual machine is a set of files and these files directly in your data store.  If you have a large store of data with multiple virtual machines, you must replicate the full data on the alternative site store in order to get to that data.  You can't really use greater SAN replication for just the simple vm in a data store.  SAN replication is not really aware of what is stored on it, she replied just blocks he knows.  You can copy the vm files individually as well, but it's more than a copy and not replication.  Otherwise, if you are concerned about vs some other vm, then using a small LUN would work better for you, or warehouses of data at multiple levels allows you to replicate the vm that are important to you and put the rest in a larger data store.

  FCIP/FC/IP doesn't really matter.  Until a table can talk to each other, you're fine.  Our secondary site is hundreds of miles away, and replicate us very well during the period of INQUIRY, from one table to the other.

  Yes, without SRM, you will need to manually register a virtual machine at the time, or write a script to work through all the.

• 3rd party such as san replication solution: strategy

  Dear Experts,

  Can you please share some of your ideas.

  Oracle DataGuard comes free with Oracle Enterprise Edition (EE). The only reason why a company could NOT use Oracle DataGuard is because they are not on the ERA and the cost of upgrading to EE just to use DataGuard does not justify the price.

  With 3rd party such as san replication solution. (for example hp3par)

  It is obvious that the all-flash backup can be quick.

  What should be the strategy to have DR site get a few seconds, if the primary site failed for some reason any

  1. daily incremental backup with RMAN. And archive backup runs for every 1 minutes

  2. so that the DR site facing up and running within 60 seconds, it still requires too much time to restore the database on remote site and have archive APPLIED setpoint

  What could be the solution with san replication? RTO = 60 seconds

  Thanks ivw

  Hello

  Great topic, I'll try to summarize all this in a post.

  I have worked with HP EVA for a few years and I must say that I have used many of the features of replication - HP EVA Business Copy (local replication) and HP EVA continues access (remote replication) as well - for the oracle database and other applications as well. Most storage systems use copy-on-write to create two points in time of the LUN (snapshot) image or clone LUN using cow again.

  Of course, like other people, said earlier the replication SAN is block based, in the same way with Dataguard, you have synchronous and asynchronous replication. When your data is written to the data files it usually goes in storage cache and then is pushed down the disc as soon as it will be more efficient, at the same point, replication is pushing data to the Dominican Republic. The same way with Dataguard if you use synchronous replication that you won't get you "speedy return" until the blocks of primary storage has been written for DR storage system.

  I never had problems with replication to be honest. I used a lot of copy of databases of production using local replication. For example if you want to quickly test a patch on the production system, you can create a snapshot that will only increase with the amount of changes you have made. The only concern is nowadays though we use ASM so if your diskgroup names are the same in DEV that the PROD does not work the approach that I mention.

  Regarding remote replication - because you do not have Dataguard more every time you failover to the Dominican Republic to your database will pass by instance recovery!

  Regardless of the type of replication is not the speed but the latency of the network - SAN or Dataguard, you will always have a penalty of a long replication distance. The biggest typical WAN latency factor is the speed of light, via fiber optic cable, which is about 124 miles per millisecond. Based on that you can calculate what would be the round-trip latency time.

  Indeed for many people SE installation choose DBvisit Standby to manage their databases on hold. I did the installation of the couple and it is really simple and works out of the box. However, your RPO depends on how often you switch your redologs and how many times you ship them to the backup site. You must configure dbvisit to spend with each log file (all the 5,10,15 minutes) OR configure archive_lag_target to configure OR use both at the same time. Also, you can store a copy of the archivelogs on a separate location just in case, for example, an NFS share.

  And finally my five cents on RAC on Clusters of extended - be careful with this one. Each of the nodes in the extended database cluster need access to both storage (primary and DR) systems. You must also third location to store a voting quorum disk, usually an NFS share. It is also very important to note that the latency between the nodes is of crucial importance due to global cache activity.

• SAN replication for fault tolerance

  Hello world

  I hope that someone could point me in the right direction - it seems that I do not have enough review in the subject and the deadlines are too tight for me to explore different scenarios in depth...

  We have two data centers a few miles of each other connected by 100 Mbps link. Each datacenter will have 5 blades BL490 with ESX Standard accommodation about 50 VMs. ABC message a HP eva4400 SAN with SAN replication implemented. VC will be the first data center and the two data center are networked.

  SAN replication is block-level, so it seems that I can not just replicate changes, but all entries will have to be replicated. This should not be a problem because the link can support about 1.8 TB a jouret of data can be buffered.

  I am not however a vision how recovery would work in this case. We don't need instant recovery, I would say that 4 hours of recovery time is accepted if SRM fancy Automatic as DR scenario would not easily be accepted financial reasons, but your comments are welcome.

  Current idea is the following: replicate LUNS of primary site to the secondary. When disaster strikes, personal COMPUTER turns on the ESX host on the remote side and connects replicated LUNS, and then registered VMs and change my IP address.

  I understand that this seems horribly manual process and I'm pretty sure I missed some obvious pitfalls here.

  Could someone let me know which direction should I go? An article on the subject?

  This is a new installation and we prefer to put in place the basic recovery process and resize it later. I just need to have a good direction to allow this scalability.

  I thank very you much in advance!

  I think you have a good understanding of how it should work it is something I would like to implement, but use Veeam as support for replication. Here's what I would do for the IP addresses of the virtual machine. I like to keep the same IP addresses because I know that not every simple VM uses DNS for all of its applications, databases, etc. So unless you are POSITIVE you covered all the basics of your DNS, I'll try to use the same IP addresses. You just work on the part of this routing before start you your virtual machines. So make sure that when switch you or test your virtual machine failover, you make sure that if you have a virtual machine with the IP 10.10.10.10 with two Datacenters A & B, the routing would ensure that all your customers cannot talk to the datacenter B until you do this active way. In this way, you can test your failover

  SAN storage replication, can it be used in my scenario?

  I have no option to implement oracle Data Guard as its very expensive.

  --> If you want to use the data that it is free of CHARGE, additional license is not required for normal data guard

  --> additional license is only for the ADG

  Is that what someone achieved something similar with SAN storage replication?

  I have oracle SE.

  It is obvious that the all-flash backup can be quick.

  --> Here, I understand that if oraclle EA is going to be expensive

• SAN replication vs VMware SRM on?

  Hello

  I wonder when should we choose as VMware SRM on the owner SAN replication method?

  for the moment, I see a plan of the DR site that would be well if my production environment data can be reproduced by the SAN in the DR site.

  Thank you

  SRM is nice, because it gives you a a (wonderful) DR failover button

  Of course, the disadvantage is the cost and the fact that once you have switched, you will need to reconfigure to backspace.

  SAN is generally cheaper (because the assumption is that you should replication stoarge for SRM anyway), but requires scripts on measurement or manually export and import of virtual machines to operate. It's also a bit harder to work around the question if your VLAN don't is not strained between sites and if the INVESTIGATION period.

  If you're used to the script thouhg, it shouldn't be a problem, so your decision simply come sdown to ease of use, cost and skills,

  Personally, I scripted before and would take the same approach again (even if the SRM is a very good tool) - but I think it is different for a lot (more) like not everyone a) the script, b) trusts their scripts.

  Finally, if you pay someone to adapt, it will be easier to understand what is happening with MRS with a bunch of custom scripts and SRM allows 'dummy runs', which scripts cannot do.

  Good luck and post with your final word please.

• Satellite A300D and ExpressCard Remote control

  Hello guys,.

  I own a Satellite A300D-135, y at - it an available for this model remote control? I'm looking for a remote control that fits in ExpressCard location as some HP models have.
  I looked at several Dutch hardware well known, but I can't find a remote that fits the ExpressCard location.
  I give many presentations and therefore use my laptop a lot. I would like to have a remote control that fits in ExpressCard location because that saves space and a remote control of such a size is easy to "hide" in your hand.

  Kind regards
  Hunterseaker

  As much as I know Toshiba doesn t offers remote control for this model of laptop. The question is whether a third party product is available on the market.
  To be honest I have no interest in something like that, but I just want to recommend you to visit the web page of Logitech. They have so many products for PCs and laptops. Maybe they have a solution for the remote control that you can use with your laptop.

  If you can find some interesting product please post the link.

  Good luck!

• WMC and RF remote, "do not detect the IR receiver.

  I'm setting up WMC and spin on the common problem of "cannot locate the IR receiver". I decided to go for a RF remote that I don't have a direct line of sight between the components. It is a remote control designed for WMC. I have everything plugged in and works. The remote is to talk to everything, including the set - top box. But WMC will not recognize the RF Receiver to replace the IR.

  I took a glance at the manual to
  http://www.gyration.com/index.php/us/support/downloads.html
   
  It seems that you have to "bind" the receiver to yourPC and buttons
  along the top to determine how it operates in (IR for decoders, RF for)
  PC, etc.) and that there may be software, you must install - I can't tell if
  the software is just to control other things.
   
  You must install the driver software for the computer first, then plug it
  USB cable for the receiver. If you have an onboard eHome receiver, you can
  to disable it in Device Manager.

  My SVRHDT1000 is connected to a Bravia 32EX650 and I have problems with the remote control RMT-J259. I have read and tried various suggestions without success so will try to buy a new remote control. Problem is that the remote number does not appear to be updated; any advice on places where but a real replacement?

  Hi DoreiL,

  Thanks for posting your concern. Model SVRHDT1000 number you provided seems to be not not an American model, and we are not able to verify the specifications. It would be preferable for you to contact the nearest offices/Sony Sony representative of your place of residence offices in the Asia-Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific.

• blue screen nvlddmkm.sys for nVidia GeForce 9500 M on studio dell XPS 1340. recently upgradeed to windows 7, fine for a while but now cela and has many problems: BSOD, freezing, CPU utilization more... I DO __HOW FIX IT?

  Hi, well bad get right to it. I have a dell studio XPS 1340 and have recently upgraded to Windows 7 last week. everything was fine until last Monday. When I switched high performance mode for my battery, my nVidia card also goes to Boost Performance. but this time, I got a blue screen with this:

  nvlddmkm.sys

  PAGE_FAULT_IN_NONPAGED_AREA

  Since then I tried to update the video driver from the dell site and even the nVidiasite. one of them gives me a blue screen as soon as I get to the windows login screen. and the other divides my GeForce 9500 M into its two parts > GF 9400 MG + GF 9200 AMS. When this happens, I can't use the nvidia Control Panel and I can't go to boost performance. I have uninstalled and installed these drivers in safe mode too, but no luck. I system restored before the weekend, when everything was fine, but still the same problem. so now, I have the driver 8.15.11.8633 version

  other side effects I've noticed is that Skype does not work either. When I first upgraded to win 7, Skype has worked well. but now, when I run a video or normal call, my computer completely freezes. In addition, the games I play seem to decrease in performance. I used to be able to play very good Burnout Paradise, but now there is a significant drop in fps. also, the computer seems to use more cpu and heats more quickly. The battery life has decreased too. and when I use windows media center to connect with my xbox360, my phone freezes when I try to access a video.

  I tried the diagnostics start and the only problem was:

  Error code: 0F00:133 media suitible C Msg:No drive is present

  and today, I used the windows debugger and it came with it. im sure this is good information, but I don't know how interperate it. Please help and thanks in advance!

  Hi anchit02,

  Thanks for posting.

  The page fault has a high probability to be RAM or hard drive related.

  You can test the computer memory using the memory diagnostic tool.

  You can start the memory Diag tool by clicking the ORB start and type 'Memory diagnostic tool' in the search box, clicking on the entry that is displayed.

• Oracle Database Disaster Recovery SAN replication consistency

  Hi all

  just a quick question after a long search and not yet knowing the answer.

  What technology or configuration do I need make the eve of Oracle DB compatible on asynchronous SAN replication between cities?

  The version is Oracle Standard Edition 11 g, then the enterprise like DataGuard and GoldenGate features aren't possible?

  Entire database replication Oracle Streams don't work?

  Hello

  You can do it yourself (as everyone else used to do many years ago), to a product like dbvisit which is popular in this space (never used, but I heard good things about this). Streams can do it, but I think he uses triggers rather than redo log mining so he can have more impact on the source system.

  SAN replication is possible but probably very expensive and you should be sure it correctly handles oracle blocks - the seller must be able to tell if it is certified or not.

  See you soon,.

• vSphere replication and RDM

  Hello

  I have a site that I put in place which has Windows 2012 R2 invited with RDM in physical compatibility mode.  When I go through the wizard of replication vSphere for these servers I can configure replication for the comments and as expected I can not set up for the RDM (which is fine, I have those covered by the SRA) but on the last stage it errors with the following:

  Configure a virtual machine for replication

  VRM Server runtime error. Please check the

  Physical RDM mode is not supported by vSphere replication and there is a known issue, you cannot configure replication for VM with RDM physical mode even if you exclude this record of replication.

  Check the release notes: VMware vSphere replication 5.5.1 Release Notes

  Cannot configure a virtual machine with disc RDM in physical mode even if the disk is excluded from replication.

  If you configure a replication of a virtual machine with the physical mode, the following error message may appear:

  VRM Server generic error. Check the documentation for any troubleshooting information. The detailed exception is: HMS can not set disk UUID for disks of VM : MoRef: type = VirtualMachine, value = , serverGuid = null'.
  

  Workaround: No.

The only problem I could see because of problems would be the appearance of the player. There Spanish lables, but they show only on a computer with the operating system in Spanish. If you want the student to view the two Englishmen and a version in Spanish on the same computer, you may have two versions of the language.xml file where you have one that has the help of English labels in the 'fr' section and the other where it has Spanish labels in the section 'fr '. You would then share those files in and out of the folder located at, C:\Users\ {UserName} \AppData\Local\Adobe\Adobe Presenter\Themes, you must publish a presentation in English or Spanish.
