change the speed of the San on the hardware

I'm looking to change the speed of the San two paths (out of 4) in my HP C7000 enclosure. The speed will change from 4 GB to 8 GB. What effect will this have on the host/LUN. We use round robin path selection.

This will cause a short on some paths interruption, if they use the 4 GB railways?

Yes, you can always disable the relevant paths in the VI client prior to the interview. Even if no downtime is expected worth it, providing you to other available paths.

  • Upgrade the hardware of Dell XPS (L521x) how to perform a clean reinstall of Windows 10 Pro

    Hello

    I searched on the internet with the question that I have before doing the upgrade and the re-installation of windows. But the messages and solutions are all scattered. I really want to clear this for me once and for all if possible.

    First of all, the material that I bought for this upgrade:

    1 Samsung 850 EVO mSATA SSD 120 GB (to replace the one 32 GB (factory default)

    2 western Digital Black 750Go Performance Mobile HDD (7200 RPM, 2.5 inches)

    3 Intel (r) Dual Band Wireless - AC 7260 (802.11ac, 2 x 2 Wi - Fi, Bluetooth)

    4. crucial Ballistix Sport SODIMM 16 GB (2x8GB) PC3-14900 CL10 at 1.35v 204 pin memory

    BTW, my Dell XPS 15 L521x has an intel core i7-3632QM and an nVIDIA GeForce GT 640 M. It also comes with 32 mSATA SSD as cache for the WDC 1 TB HARD drive.

    My goal:

    1 install/reinstall Windows 10 mSATA SSD 120 GB and free 500 MB give or take for system reserved partition.

    2. use the remaining space in the C: drive.

    3. use WD Black 2.5 inch 750 GB HHD for cold storage

    4. Remove and reinstall the wireless card Intel Dual Band for a better Wi - Fi compatiability for most routers dual band out there. (Factory default, well, is not great to say the least)

    5. Remove and then install the crucial RAM (compatiable with L521x) is to upgrade memory of my laptop (maybe a little future-proof;) (D).

    Before you start the upgrade, I know I have to do the following steps:

    1. update my BIOS/UEFI. (I did it)

    2 clear accelerated Intel Rapid Start Technology (IRST) GUI (my laptop keeps inviting that "your system does not have any intel repaid with start technology").

    3. change Intel Smart response Technology (ISRT) to AHCI in BIOS

    4 back up my files

    5. my 10 Pro Activation of emergency Windows (how exactly? The Win10 Pro is upgraded to Windows Pro 8.1 with OEM Dell)

    Now my question is what I do or what I've been missing so that what I will meet errors or problems if possible.

    Also, I have heard or seen something on the OEM of Windows version. If I change the hardware, disk files or recovering backup activation does not recognize my device. Is this true? If necessary, I can buy a new version of Win10 Pro retail. But, what I really need to do, and does it perform a not-so-complicated work around?

    Thank you very much

    Dean

    If you keep your motherboard you have no problem taking the other components such as SSDS.

    Your system is already a Pro 10 Windows device.

    Installing clean with 10 Windows installation media Pro TH2 your OEM Pro 8.1 Windows key will be automatically entered to the UEFI BIOS and Windows 10 Pro TH2 automatically reactivates when your systems online.

  • Change the HBA speed with the management console

    2 questions;

    Can we change the HBA, AUTO up to 8 GB speed via the management console, or only in the BIOS? and if yes, what is the command?

    It is preferable to set the SAN, Brocade and ESX HBAS to 8 GB instead of AUTO?

    Thank you

    AUTO will negotiate to the maximum speed that your system is capable of, so if it's 8Gb, he chooses to 8 GB.

    Help, please

    regards James...

    Hello

    Unfortunately, this is not possible on the laptop.

    I o year owner of 3 different computers; two laptops and a desktop PC. The BIOS on the desktop is different and allows to change and increase the CPU. But the laptops BIOS does not allow to do something similar.

    Why? Because the CPU overclocking would increase the internal temperature and make portable is not stable and perhaps that it would infringe the motherboards and CPU!
    The notebooks run with maximum efficiency. If you compare the notebooks modules with cooling Office cooling modules you will see the difference!

    Please don t waste your time and don t find any possibility to overclock the CPU and the FSB

    > I mean with power of change in BIOS, I don't have the option advanced on my BIOS so I can't change that... Any ideas?

    You cannot change fan speed yourself, because there is no option in the Bios. I also tried to change with utilities like a fan speed control utility. But I couldn't stand it. Perhaps, someday they will out of the Bios with support for fan speed control. :)

  • Cannot change the speed of the WiFi with WN3000 Extende range

    Hi all

    I try to change the speed of the WiFi after successfully connecting to the WiFi network original and extending it with the WN3000. But the drop-down list is blocked. When I connect to the network original WiFi directly speed is up to 300 Mbps, which is why I thought I could also change in the range extender.

    Any idea?

    Thank you!

    Daniel

    Hello danaldo

    Then, this is why he is not allowing the 300 SBM because your main router is out which and the Extender that will reduce by half for all the devices connected to the Extender but not if they are on the network from the router. Here is a good article explaining this.

    Hello

    I have a laptop of m6 - 1158ca HP Envy (Intel i7 3632QM @2. 2 GHz) running Windows 8 Pro 64 bit with 8 GB of RAM. Supposed to be 1600 MHz RAM speed, but I don't see that 800 MHz through a third-party tool (CPU - Z).

    Are there settings in the BIOS I have change to change this?

    Thank you
    Véronique

    N ° there is no option in BIOS OEM that allow you to change the speed of add-on memory or speed of the bus.

    It is an option that is present in passionate desktop motherboards.

    Computer Systemboards laptop OEM and microcomputers have less optional parameters.

  • Change the bios on my hp pavilion dv5-2135dx of 1333mz to 1866mz on the speed of RAM.

    I have a hp pavilion dv5-2135dx laptop and I would like to go into the bios and change the speed of the RAM ddr3 1333mz to 1866mz.  I bought two chips hiperx plug-and-play of the kingston ddr3 4gig and they are set up to accept the upgrade to speed the1866mz.  I need to know if it is possible to do this procedure and if this is the case, what is the procedure to make this change.

    I have a hp dv5-2135dx and I would also change the computer's bios to speed my RAM in 1033, because it is the actual number of the speed of memory ram bios shows that memory 4gig-2 chips can be improved is 1866.  HP, why don't you update the bios to accept the speed of the ram of 1866, if memory chips can be accelerated.  I don't think the upgrade is so difficult to create by upgrading the bios of your Indian coders geniuses.

  • Change the setting for the acquisition of IMAQ1394 speed by program

    Hello

    I use a pilot LabWindows/CVI and legacy NOR-IMAQ IEEE1394.

    I want to put the acquisition of speed setting in my program.

    MAX can do (there is a drop down menu to change the speed of 100 MB / 200 MB / 400 MB.)

    How can I apply this in my program? The problem is that I can't find the attribute to modify.

    For example, for the brightness, the attribute IMG1394_ATTR_BRIGHTNESS is?

    But for speed?

    If I take a look at niimaq1394.h I see a data type of enumeration, but nothing else on the speed.

    Any help would be appreciated! Thank you.

    Kind regards
