Is the addition of an effect of measure performance?

I have a DELL lab using RAID 6 Server. After you have configured the RAID on the controller, when I go to add storage on the server ESXi5 I see 1. 8 t (7) lun. It would be better for me to combine the LUNS in a T 5.4 and 7.2 T LUN using extensions. Is there a downside? Readers will be be housing databases tests so performance is not critical.

Thank you

There are benefits to the use of extensions like either. the queues by the data store and so on.

However, there is also a complexity of management and a risk in terms of availability that the metadata is stored on the first logic unit number and if you lose the first logic unit number you lose the entire data store.

to vSphere5, I see the extensions use case to be very little and prefer the only measure of storage of data...

There is also a good bed here:

  • the addition of two unequal dimensions 2D arrays

    Hello everyone,

    Once more, I have a very basic question. I try to add two tables with different line size 2D. the function "create array" creates a 3D Board. I use the array function to reshape to convert 3D table a table 2D. It works fine if I have two table of the same size, but if the size of the row of the first table 2D is less than the second, it is added an additional line of zeros between the two. I can understand why she is doing this, but I don't know how I could avoid it. is there another effective way if the addition of tables without creating a 3D table?

    The example I've been working on is attached.

    Thank you!

  • Asks the plugin noise reduction effect-made clip jerky and slow down after application?

    I apply an effect - the neat video Plugin to reduce noise. for some reason when I apply the effect, playback of the clip is really slow and jerky. Why is this?

    Hi Dragonsfire,

    I'm looking at the rendering time and it's extremely slow, like the clip is 30 secs long 2mins but render time estimate is like 3 hours! My laptop is not the fastest, but it is not no more ancient. Any suggestions on the reduction to make time-no understood them with a much more powerful computer!

    You have met one of the intensive more rendered effects on the stage of post-production. Sorry if you think that something goes wrong. Likely, that's fine, except that it takes very long time to process images with that plugin.

    Here are some tips on the neat video forum:

    The real rendering for your clip speed should be around approximately 2 images per second. This value seems normal for a HD (1920 x 1080) image size and material to the average (you don't mention your hardware specifications). You can speed up a bit by disabling some of these filter options:

    • disable the very low freq, high quality options
    • some of the fixed noise reduction in some or all channels amounts (luminance / chrominance or Y/Cr/Cb) and/or ranges of frequency at 0%
    • reduction of the time filter RADIUS
    • disable the option of adaptive filtering

    These measures allow the filter a little faster, but at the expense of the quality of filtration reduced. Noise reduction is usually a compromise between quality and processing speed. When you need good quality, it makes sense to give some time to the process with the top of the settings page. When that is not necessary, you can use a less accurate and more rapid filtration.

  • No problem with the addition of a Kingston SSDNow V300 240 GB SDD to a D7-1245dx?

    A knowledge of any problems with the addition of a Kingston SSDNow V300 240 GB SDD to a D7-1245dx? Its size is 7mm width 69,85 mm x depth 100mm height but not sure of the size of the computer laptop berries/caddy supports

    Decide whether to use the laptop for a little longer so to upgrade the system to a Kingston 240 GB SDD drive and move the current drive to the secondary location (already got 2nd coming of caddy). It lets me do a bit more space on the laptop in addition to increasing performance.  Figure between an SSD and get up to 8 GB ram it should last a little longer.

    You will have a shopping cart for the SSD, but it looks like you have an and get a second wagon. Dv7-1000 series does not use a cable or connector. the hard disk plug right into SATA ports on the motherboard. 7mm drive has the connectors SATA and the mounting holes exactly in the same place as a 9.5 mm drive. All is just shorter so the reader rides low in the caddy. As a swimming pool with 20% water let out. 7mm SSD works perfectly. Windows 7 or 8/8.1 are preferred; Vista is not configured to treat SSDS as well or easily.

  • The upgrade and the addition of material

    Hello

    This is my situation, I'm in music production, and I need to upgrade my PC to fit my needs. I'm looking to upgrade memory and RAM as well as the addition of firewire ports. The firewire port is very important because I need to connect an audio interface I. I know that I can get all these components, it is clear the fact that I don't know what is compatible and it would be better for me.

    I know I should be able to get the 16 GB of RAM, which would be much more than the 6 GB it holds. I only NEED 1 firewire port, but having 2 would be nice.

    I don't have a lot of money to update everything, so I'm trying to get what I need, and then I can save the rest.

    HP-Pavilion p6716f

    Windows 7 Home Premium

    64-bit operating system

    I have not upgraded the PC anyway, it is still stock.

    Thanks in advance for your help.

    You are welcome.  Thank you for the additional information.

    When upgrading memory, you must always match the memory that is already installed.  Otherwise, the new memory may not be compatible.  The motherboard of your computer is the Architecture Dual-Channel.  Therefore, it is better to install matched sets.  This is the memory that is recommended by Crucial.  They make very good memory.  In fact, HP uses their memory in a large number of their computers.

    This is a Firewire card that should work for you.  It has 3 external ports; (400 Mbps)-a 1394 and 1394b (800 Mbps).  If you decide not to buy this card, it is a good example of what you need.  You can watch other on Newegg to see what else is available.

  • Adding items to the tree in an effective way

    Hello

    I am trying to add items in the tree.

    The problem I am facing is, I have to update the tree constantly and add elments.

    To add first items bit it takes less time, but as the tree grows the accumlated gets.

    Demo Vi is attached for reference.

    Any HELP WILL BE GREATFUL. (vi ATTACHED IS in 2009 version)

    First of all, 1% for calibration of time Windows is 'no difference '.

    But indeed, the update of the front panel is not the factor limiting here: this is the number of children-entries that create problems. So with zero children (as I did in my first test), to postpone the updates done grant you a huge performance increase as is the one and only overhead.

    In your case (100 children), defer updates is disabled the relevance as the method 'Add items' takes awhile.

    I agree that the performance impact is huge, maybe too big, to increase the number of children. But on the other hand, you must understand that you are dealing with arrays of cluster... is in fact a big effort for the memory manager to allocate enough memory, copy of things around and (internally) the deallocation of memory. It's the more data, the most important, this will create. Therefore, it will get slower the more data that you add. But certainly, the measure is surprisingly high.

    But nothing you can change.

    To the last comment: why do you need a tree that changes many times during execution while maintaining several 100ths of elements in any combination of parent/child?

    Hi abgolf3,

    The question may be how the new hard drive has been formatted.  Take a look at the way in which the reader is implemented by clicking Start > Control Panel > Administrative Tools > double-click on computer management > double-click storage.  Is all the space on the disk are responsible?  If so, take a look at these two documents for your problem:

    Mark a partition as active

    Format a hard drive or partition to NTFS format
