Strip UCS RAID 5 size 128 KB - why?

Why the recommendation to use a size of 128 KB on RAID 5 Strip bays on rack of servers? By UCS documentation there doesn't seem to be an increase in performance by up to 256 KB. The recommendation is here:

http://www.Cisco.com/c/en/us/TD/docs/voice_ip_comm/CUCM/virtual/CUCM_BK _...

Thanks in advance.

There are performance issues observed in servers that have been mistakenly delivered with different band than the default 128 KB size

  • C260 UCS Raid configuration

    I have a question more specific. I have a UCS C260 filled with 1 TB drives. I have two controllers. In the service/config guide, it is not very clear on how to configure the berries. When you go to automatic configuration on the WEBBIOS configuration screen and use the new configuration, it shows only 8 disks and you must select a contorller.

    What second card selected, it shows only 8 disks as well and they are 0-7 identical to the first drrives card. I suspect that this is normal. I guess my question is what someone did this and how did... You set the first card and readers as bootable and I gguess it is the table that install you VMWARE on.

    Usually in the 210 c feet I create two tables. I use 200 GB for Vmware to isolate him on his iwn palette, then the rest of what I build. This is my first 260C that is why confusion... I also see the 260C can come in three configurations different one who has a unique card, one with two cards and I forget the third.

    -This isn't logical.    And any help or advice would be great.

    Thank you

    Mike,

    This might help

    http://www.Cisco.com/en/us/docs/unified_computing/UCS/c/HW/C260/install/RAID.html#wpxref36524 go to table C1

    The C260 has two different styles, berries, 2 independent 8 disk bays or 2 drive bays of 8 discs at front with an expander control. If you have the Expander version, a Raid Controller will have access to all 16 drives.

    Looks like you have independent drives with a controller berries separate Raid will each drive Bay giving that individual access to each 8 HARD disk drive Bay.

    During POST, you see two instances of the WebBIOS of LSI utility that correspond to two Raid controllers installed. Each instance of the utility will allow you to configure each separate drive Bay

  • RAID block size and Lightroom

    I setup Raid 1 (mirrored) on two drives of 1 TB and in the choice of block size, this issue was raised. What size of block is best when using raid drives for Lightroom catalogs and dng, jpg and tiff files associated with each catlg? Currently, I selected 128 k because 90 percent of the cases are from 1 to 20 mb in size with a 6-9 mb avg. There are a few files to 20 k - 500 k.   Any suggestions or ideas? I'm on the right track for the use of space and a good performance? I do not seek for its remarkable performance space is use is my main concern.
    Steve

    Size of allocation RAID will affect the use of the space.  Use of the space is determined by the size of allocation unit file system.  For a file system that is for the most part, image, size files important allocation (64 +) is a good thing.

    Distribution RAID size must be at least the file system allocation unit size.  128K is a reasonable size for images for the performance.

    Keep it defragmented.

    I'm working on my homepage with the last muse 2015.1.0.2309

    Fast 2 questions please:

    1. when I started my drawing with the global "Hi-DPI" setting and would now go back to "standard" why muse record 2 different size jpg image, even if I've cancelled "Hi-DPI" setting?

    2. when I export my finished site in a folder on my imac, why muse implements a PNG to a jpg image, I fall into the layout of muse?


    Thank you, peter

    At your breakpoints of the site? If so, the images are optimized and exported breakpointwise.

    If you use effects, which introduce transparency, Muse needs to convert a jpg in PNG because JPG doesn't support transparency.

  • RAID 0 - size of the pagefile - MIPS - Overclocking - HD video Production

    01/06/10

    Hi HP.

    Last month I bought a refurbished

    HP Pavilion Elite m9650f
    Product # NJO62AAR #ABA
    S/N [text removed for privacy]

    Intel Core i7 920 Quad Core 2.66 GHz CPU
    Pegatron, IPMTB-TK, Truckee (HP) - UL8E, MB
    6 GB (2 GB x 3 sticks), RAM PC3-8500, DDR3,
    750GB, SATA 3 G, 7 200 RPM x 2, RAID 0, HD
    NVIDIA GeForce 9800 GT, 1.5 GHz, 512 MB GDDR3

    After a rocky start, with many BSOD and updates of the
    HP website and replace a bad stick of RAM, the HP is now stable.

    I tested this HP with Vista x 64 and Win 7 x 64 separately
    and fine tuned for high performance and he analyzed several
    time at PCPitstop.com with 'OverDrive '.

    This HP will be used for HD video Production and computer animation.

    Here are some questions that I wonder about:

    I tried separately from Windows Vista x 64 and Windows 7 x 64.

    It seems that I get an increase of about 4,000 MIPS (CPU) with Vista on Win 7.

    Is this a significant difference or not?

    Does anyone know how a difference of about 4,000 MIPS
    will or will not affect motion graphics and
    HD video production applications?

    For HD video production, it is best not to let the divided page file
    in 2 or more fragments or is it more important to have too large
    a page as your RAM file will allow?

    BIOS of HP does not access the Overclocking.
    Have ideas on how to work around this problem?
    [Pegatron, card mother IPMTB-TK, Truckee (HP) - UL8E]

    Can you tell me step by step how to configure RAID 0?

    I have two Association Seagate 750 GB, SATA 3 G, hard disks 7 200 RPM.

    They are physically installed and I have too much Intel Matrix Storage Manager.

    I tried, but I'm not sure that everything came together properly

    and I want to do it again or see a second time to be sure.

    Could you please tell me step by step how to set up a RAID 0 on this HP
    and then what I should see when I look at 'Computer' (the desktop icon)
    and the total GB of storage should I find, I see still two hard drives
    and then in Control Panel / administrative tools/computer management/storage how
    Disk management should review, etc.

    You have any other suggestions to improve this
    HP for HD video Production and computer animation?

    Thank you for your time.

    Hi Big Dave,

    Thank you for responding and for having responded to my ad in the hardware section too.

    Until recently, I never knew RAID any so I backed up my hard drive

    to try the fastest mode of 0, just for the experience and I can say that 113 MB per second is quite impressive.

    In addition, I was not sure of the steps so I winged it is best that I could.  Now, I want to assure you of the steps.

    Thanks for the link to install VISTA RAID that's just what I was looking for.

    I know RAID 0 is too risky and I am ready to return to RAID 1.

    In the two discs hard Seagate firmware is up to date.

    Thanks for the links compare NIVIDIA and ATI video cards

    and links to replace the power supply and the video card.

    Yes the GTX 260 seems very interesting, and I'll keep it in mind when finances permit.

  • WLC can result only is not supported 128 bit WEP on 1120-1200-1240 AP; s WHY not?

    When I activate the wep 128 bit on the WLC I get the message

    "Size of the 128-bit WEP key is not supported on the AP 1130,1200 models and 1240"

    Why these models (the models I use!) do not support 128-bit wep? is it possible to make them support. ?? they are supported in STANDALONE mode?

    Beware with wep and key length:

    a. 40-bit key + 24 bit iv = 64-bit Wep

    b 104 bits key + 24 bit iv in the Group 128-bit Wep

    c. 128-bit 24-bit iv plus 156 bit Wep

    Aironet, you can select option a and b and it's a little confusing because they say 40 and 128 in options where 40 reference the key and 128 references in total. Believe me count hexadecimal numbers and you will see where cisco said 128 he would to be 108.

    ex:

    VLAN 20 3 size 128 bit 7 741F07447BA1D4382450CB68F37A key transmit encryption keys

    http://www.CSE.WUSTL.edu/~Jain/cse574-06/FTP/wireless_security/Fig14.gif"/ >"

    Airespace, you can select option a and b and it's a less confusing because they say 40 and 104 in the options if 40 and 108 refers to the key.

  • Insertion/thanks to the RAID controller plug in PCIe card in a UCS C220 M3, rather than embeded RAID controller?

    Hello!!

    We have a UCS C220 M3 server with a 1 TB SAS hard drive and a controller RAID embeded, like this:

    1

    UCS-HDD1TI2F212

    1 TB SAS 7.2 K rpm 3.5 inch HDD/hot plug/disc horse sleigh

    1

    UCSC-RAID-ROM15

    Embedded SW RAID 0, 1, 10, 5, 4 SAS/SATA ports

    If I add this controller RAID PCI card to my UCS server:

    UCS-RAID-9266CV =

    MegaRAID 9266CV-8i w/TFM + Super CAP

    US $ 1,686.00

    Going to work with her, ignoring the old RAID embeded it configured?

    The question is that VMWARE is not supported controllers shipped my RAID, so I want to add an external RAID PCI controller to support VMWARE.

    I don't know if it will work.

    Thank you!!

    Rodrigo,

    The embeded controller is built and not removable, it is integrated into each C220/C240. The units are designed to operate with PCIe controllers and mezzanine table when it is properly configured.

    Once you install the controller of the SIPC, you will need to do the following:

    (1) move the conectors mini SAS to the motherboard in the LSI PCIe controller

    (2) make sure that the slot PCIe what optionrom is enabled in the BIOS. (newer systems have their OptionROM disabled in the uninhabited slots (from the factory). If you do not see the OptionROM for the POST, then go back into the BIOS and enable the slot PCIe OptionROM

    (3) while you are in the BIOS, you can thus turn off Patsburg UCS regulatory table (the table embeded). It is of no use at this stage that you removed the cables up to the HARD drive Bay. It is also misleading if left active, you will see the configuration of arrays of LSI utility appear twice during POST. Time for the embeded and once again for the PCIe LSI controller.

  • Understand the examples of the FIDL: why 4xI16 samples are packed in 1xU128 and not 1xU64?

    Hello

    I was studying examples pre-built in point 1.3 of the FIDL and was intrigued by the details of an implementation. Engine acquisition - Facade.lvlib: Packer.vi takes 4 x I16 samples and packs them into a value of U128. Don't lose that 50% of the bits? Why did he Pack data into a U64 instead?

    In which case it is important, I'm mainly interested in engine CQI on 5734 SMU - 7962R.lvproj. (Packer.vi looks like a generic VI is shared between different projects however)

    Hello!

    I'll take a look at the white paper, Three Steps to effectively using the NI FlexRIO DRAM. To sum up, different configurations of DRAM have "Access different size," which is the number of bits per memory address. If access size = 128 bit and you try to write 64-bit memory address, the other 64 - bit are assigned an arbitrary value by the controller memory in a less-than-ideal way.

    To maximize the flow through the DRAM interface, it is recommended that you write a number of bits correspond to the size of the access. For modules SMU-796 x FPGA, the size of the access is 128 - bit, so it is logical that we are packing 4xI16 values in 1xU128!

    Let me know if you have any questions.

  • How to activate RAID 0 on my W700

    Madam/Sir,

    Would you be so kind and explain briefly the procedure to recreate the image on my W700 with an AHCI enabled (non-RAID) 2 disks in an active RAID (2 stripped drives - RAID 0).

    I already have a picture of rescue & recovery of my disk (disk 0) main system on a drive connected to my W700 dock eSATA external. I also have a CD bootable rescue & recovery.

    My doubt is about the creation of the RAID 0 volume 1 and if the rescue CD & recovery will be able to apply the saved image on my RAID 0 volume (100% of the space of 2 discs)?

    Please notify.

    ionelg, welcome to the forum,

    Are your hard drives of identical sizes? If this isn't the case, you may forget to build a RAID configuration.

    You need to create recovery discs as well, just to be on the good side of you. Go to start > programs > ThinkVantage > create recovery media. (It's a belt and Suspenders question - to be on the safe side).

    During the startup process, will give you the opportunity to press CTRL + I; This will allow you to set up your RAID as you would like, at the same time, it will make your current config as useless and all files will be lost - to return to them first.

    After you set the drives to the RAID configuration, you need that you can then use your discs to install the system. From my experience, it seems it won't boot from the disc or any other media get there in the first place, but it does eventually.

    Hope this helps

  • Conversion HP Envy H8 - 1413C of disk in RAID (preloaded Windows 8)

    Here are the steps I took to convert my brand new HP Envy H8 - 1413C
    a same drive "C:" to a matrix RAID-1 ("mirrored").

    There are some 'extra' parts you will need:

    * a "spare" SATA, at least 120 GB, which does no file important to this topic.
    * at least 5 writable DVD - R or DVD + R blank discs.
    * two cables SATA.
    * marking pen to write on the 5 writable discs.
    * a 16GB (or more) USB memory-stick, or writable CD - R discs.
    * two screwdriver - flat head, a Phillips (cross) head.
    * a new SATA disk drive, the same size and manufacturer and speed (7200 RPM)
    and speed of transfer of data SATA as the Seagate 2000 GB-disk drive factory installed.
    * a small pair of scissors.
    * a few screws (you will need to hold the new disks in its place).

    1. on your current computer, go to: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=cp-110846-1
    Download the file "sp58558.exe", which is 12,92 MB in size.
    2. save this file on the memory stick, or burn it to CD - R disc.
    3. remove the HP Envy H8 - 1413C from the package delivery system.
    4. only connect the keyboard and mouse, display and power cord.
    Do not connect to the Internet and don't connect to a PictBridge compatible printer.
    5. connect the screen and turn it on.
    6 turn on the computer and immediately and repeatedly F10, until the computer enters the installation program.
    7. in SETTING mode, press the right arrow key and press the arrow key once down.
    8 change the mode from AHCI RAID disks (which includes AHCI).
    You can use the "Advanced" options to set the delay to 5 seconds.
    9 economy-and-exit installation mode.
    10. leave the Windows 8 start and finish setting up Windows.
    Don't worry about issues during Setup.
    This installation of Windows 8 is only "temporary."
    11. Once Windows 8 is running, press F1 for, type 'help '.
    12 get in 'Help' for more about 'create a system recovery disc '.
    13 run the program suggested to create system recovery disks.
    You will use these 5 writable DVD discs.
    14 label 5 discs. Do * NOT * lose them!
    15. shut down the computer.
    16 unplug the AC power and remove the side panel of the computer case.

    21. remove the cage.
    22. use the screws to mount the "spare wheel" SATA drive in the cage.
    23. carefully use scissors to cut the cable tie in plastic-the wind, to release another outlet 'power' of SATA.
    24. connect a spare SATA cable on the disks 'in relief '. Leave the other end free.
    24 start to set in place disks cage in the motherboard.

    41 see the SATA ports on the motherboard - the 2 closest ports to the TOP of the computer
    are the (faster) 6 GB/s ports, while the other ports are (slower) 3 GB/s ports.
    42. If the DVD drive SATA cable is connected to one of the two ports, 6 GB,
    compress the end (to unlock the end of the shooting) and move the end

    43. connect the cables 'pair' of disks SATA 6 GB/s ports.
    44. connect two Sockets "" SATA to the 'pair' of discs.
    45 lower the cage into his house and screw it up.
    46 put the "spare" drive (which now has the 'temporary' copy of Windows 8).
    and drag it into the empty location of 5.25 inch "under"the player. "
    47 connect the power and data on this drive,
    and connect the other end of the data cable to one of the SATA ports on the motherboard.

    76 open the windows 'Control Panel'.
    77 open the "Windows Security Center" app - install Norton disabled.
    78 select "Windows Defender" (before Windows 8, this software was named "Microsoft Security essential" free anti-virus).
    So, instead of paying $$$ after the end of the period of 'test' of Norton, you have FREE antivirus software.
    79 connect your printer (Windows can connect to the Internet to download device drivers).
    80 run Windows Update to get the latest updates and Windows Defender, your printer for Windows 8 itself.

    So, you have installed Windows 8 * THREE * times.  Fun, huh?

    No thanks to HP, to make the RAID Configuration utility a Windows application only.
    rather than make accessible mode of BIOS CONFIGURATION.

    Thanks to HP for not identify 2 SATA ports on the motherboard are only two ports "fast."

    No thanks to HP for this 'sp58558.exe' file _not_ put it back in the software.
    unless the motherboard went from "AHCI" mode in "RAID" mode
    This is probably why the 'preloaded' version of Windows 8 does not include this software,
    force the user to download/install separately.

    Questions?

    Hi again,

    It's weird because all of the Intel RAID drivers I used install in AHCI mode and I use 11.6.0.1030.  I then run the MS MrFixIt fix and that I start.  However, I have not tried with the W8.

  • RAID on C220

    Hello

    I have a C220 server with raid UCS-RAID-9266CV of the card into the PCIe slot.

    I need to remove this card in order to use for an extra NIC PCIe slot.

    Can I use the embedded MegaRAID controller to set up RAID 1 on integrated SAS drive?

    It seems to me that the migration is not possible...:

    -I don't understand why; have I not a... software solution?

    -If I can, what should I do about the BIOS, wiring...?

    Thx a lot

    Nicolas.

    Nicolas,

    If you ordered the server with RAID controller then he came with built-in RAID key to be installed on the system board.  You'll need to order the following parts and install on the edge of the system in order to use the integrated RAID controller.  It is important to note that ONLY windows and Linux are supported.  To order the part as a spare just add an = sign at the end of the PID (e.g. UCSC-RAID-ROM55 =).  It is a key that plugs directly into the card system that allows the on-board controller.

    The cables connected to your 9266 can be re-used and connected to the SAS connectors on the system board. Once you have the part and recabled, you need to activate the controller embedded in the BIOS.

    What should be the size of parity when running 2 x Samsung 850 SSD Pro connected to a H710P in a R720xd PE in a matrix RAID 1?

    RAID 1 is not a type of parity and you do not set a size of parity. I think you're talking about the size of the stripe.

    The size of the band does not have a big difference on a RAID 1. The size of distribution is most important when you spread data on multiple disks. The size of the stripe can have an impact on the performance of the table by spreading the data on the disks or by limiting access to the data to a single drive. By changing the band size, you can do your berries of access time or improve sequential access times. Smaller block sizes are generally better for sequential reads/writes as they spread usually given on several drives, and larger sizes of band segment are generally better for fast access times because the data, you have access to are usually on a single disc.

    In short, unless you are going to hire a consultant to analyze your use of data to recommend settings then I would leave it on by default. Change the size of the default distribution segment only would probably be useful in an environment of database with use of compatible file size and a RAID level across several drives.

    Thank you

  • Can verify us the scope of management for LM tablespace sizes?

    Hi all;

    Sizes of extensions that are managed locally can be determined automatically by the system.

    Otherwise, all extensions can have the same size in a locally managed tablespace.

    I created a test locally managed tablespace.

    How can I check the sizes of scope management for tablespace in oracle 10 g test?

    Most likely your tablespace is created as AUTOALLOCATE LMT. You can consult:

    SQL > set long 50000

    SQL > select dbms_metadata.get_ddl ('TABLESPACE', '') of double;

    If you see the keyword 'autoallocate' you know why extensions are allocated with different sizes as AUTOALLOCATE specifies scope sizes are generated in the system.

    If you want to create scopes with the same dimensions, you must specify UNIFORM.

    Example:

    SQL > CREATE TABLESPACE TS3 DATAFILE ' / oradata/ts3_01.dbf ' SIZE 50 M MEASURE LOCAL of MANAGEMENT UNIFORM SIZE 128 K;

    SQL > select tablespace_name, extent_management, segment_space_management, initial_extent, next_extent from dba_tablespaces where nom_tablespace = 'YOUR_EXAMPLE ';

    NOM_TABLESPACE EXTENT_MAN INITIAL_EXTENT NEXT_EXTENT SEGMENT

    ------------------------------ ---------- ------ -------------- -----------
