• SAN FISICA E Single point of Failure

  Ciao Tutti,.

  Prima di implementare UN progetto per UN nuovo client, I wanted sapere cortesemente some info riguardo alle SAN BROTHER (DELL, HP, Netapp ecc.):

  The SAN BROTHER hanno dei point single failure? MI spiego... oltre ad avere a controller, doppie nic, alimentatore ecc doppio doppio. esiste a componente called che e singolo backplane? e if as rompere questo SAN e offline?

  Pole enjoied all all di una DELL PowerVault MD3420 con tutto ridondato. my he dubbio era is esiste a componente nelle SAN BROTHER (come the scheda madre x I have server/host) che non Può essere ridondato...
  

  The Altra soluzione era quella di passare una virtual SAN... ad sapete consigliarci a sistema di SAN VIRTUALE apartment VIRTUAL SAN di vmware? e magari darci some info su Dove find advantage?

  Grazie a tutti by attenzione.

  The maggior parte degli storage company entered o middle level hanno nello o chassis backplane he loro single point of failure.

  ORA by primo of quinto if it io no ho ricordi di aver may heard parlare di sostituzione by guasti ecc.

  Mentre by her seconda della backplain Può anche understand parlo. The bkn di guasto pero worth bassa che viene e no may almost considerata.

  Questo perched if di is a componente del tutto passivo. E' una scheda elettrica di interconnesione tra i controller I have brain gli alimentatori ecc.

  Questo tipo di construction appartiene a quali prodotti HP MSA, NetApp 2500, IBM's DS, solo e DELL EMC VNX by some citarne.

  A che non condivide backplai e ad esempio una sistema he StoreVirtual di HP. In questo prodotto ogni controller e composto da Server x 86 con i suoi brain.

  SE cerchi invece soluzioni tipo SAN virtuali, you can always see it sopracitato StoreVirtual oppure I prodotti di StorMagic, StarWind, Datacore solo ecc by some citarne.

  Personally a meno che he tuo sistema sia company highly critical non mi if tanti pensieri e punterei ad uno degli storage classics di cui ti ho scritto sopra.

  SE invece affidarti ad una soluzione perched software non proprio valuti you want the VSAN di VMware?

• How best configuration connect display server and composer to limit the single point of failure?

  Hi all

  
  Just had a few quick questions:

  1.) how everyone is to limit the Connectoin Server view to a single point of failure.  All the reading I did looks that everyone puts in place two servers connectoin and doing DNS round robbin on it or put two servers behind a load balancer connection

  (2.) what happens if the mode to connect to the server disconnects while users are connected and actively using desktop computers?

  3.) how to protect View Composer of single point of failure.  It seems that most people are installing this on there vCenter server and everything by leaving it with VMware HA.

  (4.) what happens if View Composer breaks down and you have Active Desktop sessions used by users who are linked clones

  (5.) what is the login used for replication partner server view?  This is a new feature in display 6 that creats a form any cluster to the login server?

  
  Let me know,

  
  Thank you

  1. Yes. Need a load balancer. Something better than a round robin DNS since those who go ping (response from the host)-based and not necessarily whether the service is in place (port 80/443 replying with 404)

  2. the user disconnects. When the reconnection that they continue where they left off.

  3. just about everything. Also ensure that regular backups are performed by the login server. Don't forget that if you need to restore, to restore a backup SQL composer both AD LDS.

  4 should be fine. The only problem is during commissioning, a linked clone or create a delete. Then could be a problem. Updating should be ok

  5. a replication partner? Do you mean the replica server? It's just an identifier during the installation as to whether, during the installation of the connection to the server, create you a new instance of the view or expand an existing one. He ends by as a peer to other servers to connect in the same instance (POD).

• Single point of failure/Cluster/high availability on Essbase 11.1.2

  Hello

  The project I am currently working has only one Version of Unix 11.1.2 Essbase server that's threat as a single Point of failure. Management thinking to upgrade the Essbase to superior verion 11.1.2.1 to achieve clustering & high availability and to overcome the situation of single Point of failure by having just a server unique essbase.

  My concerns here are;

  Note: Essbase in this project is used to generate reports only, write back data is not allowed.

  (1) not supported of the Essbase Version 11.1.2 Cluster / HA / failover to the other node?

  (2) if it is Yes, can you please share the link to the documentation for this version 11.1.2.

  There are other components of Hyperion as HFM, FDM used the same version in this project. If the failover is not supported in the version of Essbase 11.1.2 we need upgrade other components as well as the Essbase or just Essbase upgrade upgrade to version 11.1.2.x is sufficient.

  Please share your valuable thoughts on that.

  Thanking in advance for your ideas.

  Kind regards

  UB.

  
  

  Found the reason why Essbase Cluster does not work when implemented with failover / high availability when Essbase Analytics link (EAL) used in the project. Due to these facts, we have stopped application Essbase Cluster and the Essbase in my project remains SPOF (Single Point of Failure).

  Not sure if Oracle Corp. comes with EAL product improvements that can take over for Essbase Failover.

  "

  1. Essbase Analytics link (EAL release 11.1.1.4) does not support high availability facilities. This means that EAL cannot connect to a cluster of Essbase, always happens only connections to a server regular Essbase through the Regional service console. Although we can define availability high for Essbase, EAL will use a single Essbase server. If it breaks down another Essbase server is used, we must manually redefine the EAL bridges on the new Essbase server and re-create the database Essbase. It is not considered high availability in this case.
  2. There is no technical mechanism to link point to a Cluster Essbase-Essbase analytics. EAL is supported only to connect to a single named Essbase Server.
  3. Transparent partitions can support when configured Essbase as component availability high when EAL is used. EAL bridges in the active project uses Transparent partition.

  "

  Please feel free to correct me if this interpretation is wrong.

  Thank you

• Single point of failure?

  We were the ThinApp assessment as an alternative to the standard deployment for our (physical desktops) organization tools. I really like the features provided by thinreg.exe, applink and updated by-side.  My main concern is at this time of the potential impact of having all applications that run on a network share, both in terms of performance and downtime.

  Since thinreg is not cache a copy of the application on the client computer, I thought using the MSI feature... but it seems then you lose many of the benefits of deployment and update capabilities of ThinApp.

  How others have dealt with these issues?

  Thank you

  We recommend using DFS since that will offer HA for your file sharing... You have reason on a single file server will be a single point of failure.

  With the help of MSI, it didn't really hinder you to use the features of ThinApp. MSI is only add logic to get the package copied on the hard disk of the client. You can still use AppLink, AppSync and all the other features (updated in place might not make much sense but works)...

• Single-point PXI 8106 timed performance material

  Hello

  I'm potentially interested in buying a PXI-8106 module for my application of servo motor control. I would like to know that single-point timed material loop rate performance of this command when used with DAQmx, before buy you. Does anyone have statistics of performance for this controller to the benchmarks of NOR (http://www.ni.com/white-paper/5423/en/)? Ideally, I'd be able to get execution rate of loop for T1 to T4 tests, for 1 and four lanes. I can't find this info online.

  I am currently borrow a PXI-8108 for my setup and I can reach nearly twice my goal of 2 kHz loop rates. I also know the performance of the 8108RT to the above reference, so if I had the same numbers for the 8106 I should be able to judge how the 8106 happen for my application.

  Thank you

  Jason

  Hello

  We do not have these data posted, but looking at the specifications for these two cards, I imagine that you would see no more than a 20% drop in performance between the two.  Probably less.

• vCenter 5.5 installation failure.

  Hello guys,.

  It's a new Windows 2008 R2 server installed from scratch with all updates.  vCenter Single Sign-On, Web Client and inventory Service is installed with no problem, but when installing vCenter Server, it gives and error with the following message:

  The wizard was interrupted before that vmware vcenter could be completely installed. Check the log of the vim-vci-msi files.  I've also attached the log file, to which it refers.  I already tried KB article 2013922 http://goo.gl/tTjBMQ but no change. I don't see anything obvious that could cause the installation to fail.  Thanks for your help.

  

  I could install the vCenter indented the server in the domain, and then log in as local administrator account. Everything went smoothly after that. I don't know why it won't let me install when you use the domain administrator account.

  Thanks for your help.

• VCenter Server 5.1 installation fails on registration with vCenter Single Sign On

  Hi all

  Server 2008R2.

  The two level 5. 01b and new facility gives the same error message.

  vCenter installed Single Sign On OK

  vCenter Inventory Service installed OK

  VCenter Server installation is interrupted when the installation dialog box says:

  Recording with vCenter Single Sign On

  The error message is:

  Error 29113. Incorrect entry - a command line argument is not, a file is not found or file specifications doesen't contain the required information, or clocks on the two systems are not synchronized. Check vm_ssoreg.log in the temporary folder of the system for more details.

  Closed log file.

  Know someone at - it a solution for this?

  I had the same problem with the certificate has expired. VMware has made a new kb article:

  http://KB.VMware.com/kb/2035413

  This vcsso file is only there if you do not click ok on the error window. but you do it anyway. Look under the VirtualCenter\SSL of C:\ProgramData\VMware\VMware and see if the rui certificate has expired. mine did and after I removed all the files in there and restart the installation, everything went well, and the new certificate is valid 10 years ;-)

  hope it does not help anyone.

• pl/sql block, reading the reading of data from the table to a single point in time

  I'm trying to figure out if several cursors in a PL/SQL block are executed inside a single Point in time, and so don't see no updates of paintings by other processes or procedures running at the same time.
  
  The reason why I ask is I have a block of code as an initial extraction of data, with some Sanity Check before the code runs. However, if another procedure might modify the data between the two, then the mental health check is not valid. So I am essentially trying to know if there is consistency read in a PL/SQL, preventing updates to other processes to be seen.
  
  Anyone who has an idea?

• When I clik on a link to view another Web page or another document, a blank page appears (a single "point of png'). How can I solve this issue?

  The links are located on the emails I receive from authorized sources. When I click on the links to read the additional documents (another document) or display a picture, I get a blank page with a single point in the middle of the page. The tab header says it's an image (1 x 1 pixel) PNG. Any suggestions to fix this?

  Often, links to email in bulk are routed via a follow-up rather than service directly to its final destination. If you look at the address bar on the image page, it seems like one of these intermediaries rather than the page you expect to load? If you click on the address bar and press ENTER to retry the address, which does nothing?

  It is possible that the security software or security add-on kills a redirect from this intermediate page to the final destination. For example, I think the anti-banner Kaspersky functionality could do that.

• How to generate a single Point (On-Demand) edge counting with relaxing break

• Filtration of single-point data

  Hello, I'm trying to filter the data of voltage point unique task, but there is an error of frequency... I have set at 120 Hz sampling frequency and I want bandpass filter for example of 30 to 40 Hz...

  

  So, where is problem? I tried to use a timed loop or "align and re - sample" sampling frequency, but this filter still does not work...

  

  You know, how to use this filter with single point task? When I do my own filter FIR with the same settings, the results are not same, this is the reason why I want to use this filter.

  If I use DAQ Assistant, there is no errors, but I can't use for other reasons (1) I can't use single point and all daq assistant, daq assistant 2) can't do pressure)

  

  These images add nothing to the discussion. If you buy a single point at a time, you have NO frequency and cannot use the normal filter function. Do what I said or use multi-sample reading or single reading point and build the table before making a filter. Best is to use the acquisition of data with several samples.

• detect single-point XNET CAN timeout

  Hello

  I've implemented a CAN communication via Signal XNET single-point settings.

  I need to detect a time on the CAN line if a bus-elect is no longer active. I found this possibility for the parameters of FRAME CAN, but not single-point signal.

  How can I implement this timeout notification?

  Thank you very much

  Magnus

  Hello Magnus,

  first that I want to recommend the "single-point input Signal Mode" in the XNET help (first link in the XNET (single-point Signal) reading .vi) article for a better understanding of the feature.

  If you wish to set up an audit of the time-out period, you can use the function "XNET .vi (XY Signal) read", so that you get a delivery timestamp. When query you that you can build a lag.

  Best regards

• Finished samples timed material vs single-point: different speed?

  Hi all

  Although I had several questions about this request before that separately have been resolved, there is one last thing that remains difficult.

  Shortly:

  My application acquires data from 2 analog and synchronous inputs on 2 channels of analog output.

  There is a trigger stop set on a PFI-pipe with a single switch. To make of this

  I had to switch from single-point over acquition timed work material.

  This set works very well when I read not less then a 100 samples once with a sampling of 1000 Hz. frequency (when I go below a sample of 100 to read--> E-200279)

  Ideally, I would like to read about 10 samples with a sampling frequency of 1000 Hz.

  However, using single-point timed equipment acquisition I can easily do that without a problem. Even just reading

  a single sample once with a sampling frequency of 1000 Hz does not have a problem. But impossible to use the block of relaxation of reference as a signal to stop with this setting!

  Question:

  For me, there are two solutions, but so far I could not work on one of them:

  (1) build a stop trigger in an single point of timed material acquisition

  (2) change something in the acquisition of finished so that I can read faster.

  Any suggestions, what causes the difference between the two speeds to be able to read the data and a way to solve it?

  Thank you

  Mark

  Mark,

  I mocked how I think I would like to address the issue and tied it to the top.  The general idea is that we use HWTSP for our analog I/o and counter looking edges on our signal "stop".  Each iteration of the loop, we check if we saw the stop signal.  If we have, then we write zero for the output channels and stop the loop.  If this isn't the case, write us the data of your comments, we have calculated.  I've added some comments on the block diagram that I hope are useful.  I have currently no any material of series E share, so it may not work properly out of the box, but I thought it would point you in the right direction.

  I offer this precaution:

  Windows is not a real-time operating system.  Therefore, it may take the liberty to give as much CPU time to other processes or applications as he likes.  As a result, it is likely that you will not miss a few samples (IE, your loop will not go faster hardware issues are examples of clock).  I configured DAQmx must return a warning you when this happens.

  Hope that helps,

  Dan
