Suggestion of DR Plan

Hi all

We have a small site, where 84 VM running on the HP case Server Blade BL 460c Gen 8.

The configurations are:-

4 host ESXi 4.1.0 build 800380.

Cluster:-Single

Storage - HP SAN.


There is a blackout in DC and UPS failure. DEU failure sudden, ESXi host and storage were down. After the restoration of power, the whole army ESXi 4 increased but the devices were not started in a sequential order, which caused the chassis environment plan (FC switch) failure and the VM could not see the storage. Little VM criticized causing interruptions of factory service and we tried to restore the virtual machine to the database local from the Avamar backup, but unfortunately backup avamar (VM) was also running on the same cluster.


Now, we must plan DR so that in the future, we can prevent this kind of failure. The research of DR plan advisor.  Thanks in advance.


Thank you

Hello

Few things to note here before planning to DR.

Looking for Site resilience in the Wan?

Looking for a Dr. in the same data center?

Looking for a DR LAN/MAN networking?

Once decided above, you must define RPO/RTO for recovery during the disaster. The amount of data should be the maximum loss and the way which much time it should take up to talk about the site.

Once decided RPO/RTO, go looking for what type of data recovery? Backup of Ribbon through or asynchronous replication?

Once all responses in hand, here are some options you can plan of DR.

Plan #1

SRM (Site Recovery Manager) - since you have small infrastructure, it will be inexpensive. However as the best practices, you can go with this if the cost is not forced.

Short plan: -.

-Install the VC in two different sites.

-Install the SRM on both sites.

-Ask storage team to provide LUNS replicated to use for this VM.

-Configure SRM protected and recovery Site. See the SRM guide for more depth.

Plan #2

Use 2 sites and restore the backup to a tape in the event of a disaster.

Plan n ° 3

Use LUNS replicated for virtual machines.

Use 2 sites in different places.

Make visible those LUNS to the other site and register VM to this site, in the event of disaster.

Kind regards

  • How to make a wireless upgrade on Satellite P10 804 card

    I have a satellite P10 804 and it has a 802. 11B wireless card built (only part no PA3171U-1MPC). It's too slow to stream multimedia from my office. My router has capacity G + and I would like to update my wireless card to be somewhere near the same speed. The upgragdeable of cards is integrated (easily)? If so, is the PA3374U-1MPC card compatible? and how can I change?
    Thank you
    Shaun

    Hello

    Yes, surely. You can improve it, but you should not use original toshiba parts. You can enter a Wi - Fi card with the standard of g on ebay for example and install it yourself. the wireless LAN card must be placed on the bottom of your machine behind a cover that is fixed with a screw.

    I suggest, if you plan to buy a new one, take an atheros card because they are affordable, they are stable cards and chipsets quality is very good (send/receive/you connecting to a network) If you can´t do something wrong with an atheros chipset.

  • Can I download originals to iCloud for mac before move library of photos on external hard drive

    I moved my library of photos from my laptop on a thunderbolt 2 TB external drive. I opened pictures (option click) and chose this place to open. Then I opened the photos and click preferences on use this as library of photos of systems. I checked iCloud and he said that I had referenced files that could not be downloaded and consolidate them. I do not know which files are "referenced". These would be photos of the former library of iPhotos that was imported in the Photos. I have more than 20,000 pictures on iCloud. Will they all finally downloaded to my new library of pictures on the external hard drive? Or I have to download the originals on my mac before moving the library of photos on the external drive. I maybe need all start over and do it - except that I don't have enough space on my drive SSD from Mac to keep them all.

    Any suggestions? My plan was to have my photos on iCloud, the originals on disk external hard and then the mac and HD on my time capsule. Access iCloud on my iPad photos air and iPhones, iPad pro.

    When I look at the size of the library of photos in my pictures folder, it is about 12 GB - there is also an iPhotos library in the images folder which is 63 GB. I think I have to combine these files but don't know how to do this. If I also moves the iPhotos library to the new external hard drive which will be done automatically. Obviously I have not deleted the folders in the library on my Mac until it works.

    They must synchronize the external disk if it's where you said Photos your library is (that you have).

    Try to create a new smart album to see what is not downloaded.

    Good day to all.

    My model of signal generator (E4432B) is a GSS - D series. I had downloaded the driver concerned and I was exploring the examples given. However whenever I run the .vi program, there will be an error message invites me as shown in the picture as an attachment.

    I had read through the forum messages from various sources and suggestions of first plan was to install the driver VISA. I did, but the same error still appears. Where can I ask what are the things I can always fail?

    In addition, if it's something to do with MAX, may I know the procedure step by step on how to do it as I am new to it.

    It's the attached program: "Agilent ESG series Signal FM Config '.

    Kind regards.

    Thank you for your help,

    Hello

    I don't plan on specific issues.  You will need to reuse the existing heatsink.

    Review a couple of uTube videos of Intel i7-2600 installation so that you get the feel of what you need to do.

    I suggest that you plan to install latest BIOS update for your PC and your PC stable before you proceed with the replacement of the processor.  It could not hurt to run diagnostics to make sure that your PC hardware is stable.

    If you experience problems after installing, then try to clear the CMOS memory.

  • Calendar in XP Defragmenter

    I don't know there is a way to automatically schedule disk defragmentation in Windows XP, SP3.  I tried to use Task Scheduler, but not able to find the "program" to assign to the defragmentation.  There must be documentation on this somewhere?

    Mike,

    Go to control panel > administrative tools > Computer Management (Shortcut). Storage > Disk Defragmenter.

    However, I am not suggesting that you plan to automativically run. Your C: drive player needs 15% free space to run. I tried to run this week and I don't have enough space treatment. Instead, I'm trying to delete files on my C: drive recovery because I keep all documents on an external drive.

  • WRT54GL: Fast cable internet connection; very slow wireless

    I have been chasing a problem for months and I am at the end of my mind.

    I started with a cable modem Motorola SB5101 and Buffalo bison wrt-hp-g54.  For years, we had a (intermittent) desperately slow wireless connectivity.  Recently I started to run through Speakeasy.NET speed tests to try to find a motive.

    Wire speed is consistently running 15-16 Mbit/s, compatible with the speed promised our cable package.

    Wireless speeds were a different matter.  From multiple computers, they would sometimes as soon as the wire speed; then all of a sudden (from all wireless computers) the speed would fall to 0.5 Mbit/s or less, then the speed measured on our single wired computer remained at 15 Mbps.

    Restart the router would mitigate the problem for a while, and then the wireless would fall up to 0.5 Mbps.

    Wire speed would remain stable at the nominal 15 Mbit/s.

    Well, looked like a bad router.  I replaced it with a WRT54GL hardware version 1.1.  I've updated the firmware to the last - v4.30.16.

    I selected a channel (2) wireless network what inSSIDer 3 watch is not used by any neighboring router (i.e., no interference).  I have that checked regularly and am sure that interference is not the problem.  The router is configured for the wireless G only; WPA - AES.

    The same problem occurs with the new Linksys router.

    In desperation I replaced the old modem SB5101 with a new SB6141 cable, not believing there could be everything possible that could help but, this what the devil - we will eliminate it as a factor as possible and go to DOCSIS 2.0 to DOCSIS 3.0.

    The problem persists.

    Thus, new router, cable modem brand new, constant wire-speed, without strong signals wireless, channel interference all around. but the problem persists. There has been no improvement on the old hardware I used.

    All computers, but a (XP Pro) is running Windows 7 Pro.

    The problem is not predictable, except that the speed degradation will happen sooner or later - and this is not progressive.  Suddenly, he fell like a stone and sticks to 0.4 to 0.5 Mbits/sec.  Reboot the router (usually) will fix it for a while, and sometimes it will clear up on its own, given enough time.

    I ran inSSIDer several times while this is happening, but he sees no other no signal on the channel I use--in fact, none on adjacent channels either.

    I checked from wireless to the router table and there is no other than our device, so it does not appear that the network has been hacked.

    Does anyone have an idea what might be going on or suggest an action plan?

    The only thing I can think is that there is something between the router and the computers wireless in the House which is eating up 95% of the bandwidth wireless - a sort of voting out of control.  But what?  I'm completely stuck.

    Follow-up.  I changed the channel 1 wireless; After doing some research I realized that sharing a channel (as long as your signal is at least 20 dB louder) causes fewer conflicts overlapping channels.  I have not changed anything else.  I'm tempted to allow the break-up of the frame but implementation of that seems to be somewhat specific to the supplier so I'll let it be.  In any event the wireless speed now as fast as the wire speed.

    The result is that since the re - install the Linksys firmware and do a hard reset that I saw not a single instance of the speed problem.  So I still don't know exactly what caused in the first place, but I'm glad that the problem has disappeared, so I'll just let things be.

    Thank you!

  • Moniter turns black when you are working on computer

    I have an Acer Extensa 5420 running Vista Home Premium 32 bit and the screen will turn black in itself.  It of like when you press Fn + F6 to turn off the moniter.  However, I don't have to restart the computer to recover the moniter on, I can press Fn + F6 and move the mouse and it turns on.  I updated the driver, which is an ATI Radeon Xpress 1250 and which does not seem to solve the problem.  I ran a diagnostics of memory who reported no errors.  I contacted Acer and they suggested updating the driver that I've had and they said to do a factory restore.  I did not restore the factory, but because I really hate to do that if there is a simple solution to my problem.  I realize there are similar to this positions, but none like well my problem that I could find.  If anyone has any suggestions or responses they would be greatly appreciated.

    Hi Imzadi75,
     
    1. doesn't this problem occurs when you work with a particular program or application?
    2. Since when are you facing this problem?
    3. any recent change in software/hardware on your computer?
    4. doesn't this problem occurs when the monitor is inactive for a long time?
         
    Method 1:
    First of all I suggest you to turn off the graphics card on your computer and check if the problem persists, the problem does not happen, you need to contact your display adapter manufacuturer for the updated drivers or replace the unit.
    You must be logged on as administrator to perform these steps.
       
    a. open the Device Manager by clicking the Start button, click on the Control Panel, clicking system and Maintenance, and then clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    b. in the Device Manager, find the device and then right click on the device name.
    c. Select disables the device.
           
    Method 2:
     
    That the monitor lights up when the mouse moves, I suggest delete all plans power on your computer and check if the problem is resolved.
     
    Reference:
     
     
    See also:
     
     
    Method 2:
     
    If this does not work, create a new user account and check. If it works in a new user account, then probably your user account have been damaged and would need a fix.
     
     
    Now search for the question.
     
    Follow the link provided below to fix the damaged user profile.

    http://Windows.Microsoft.com/en-us/Windows-Vista/fix-a-corrupted-user-profile
     
    Method 3:
     
    I suggest you go the notch of hardware acceleration to none (the Basic acceleration setting) and check if the problem is resolved, follow the steps below:
     
    a. Click Start, type display settings in the search box and then click on display settings in the list programs.
    b. click on the settings tab and then click Advanced.
    c. click the Troubleshooting tab and move the notch of the slider hardware acceleration to none (the Basic acceleration setting).
    d. click OK and then click Close.
    e. If you are prompted to restart the computer, click Yes.

  • How will I know my administrator password?

    Hello, my husband needs to install some software manufacturer, Sat - Nav and it asks the administrator password.  I do not remember what it is and have tried all the other more obvious.  How can I retrieve or reset my Admin password please?

    When you have loaded Windows for the first time you have been prompted for the name of an account and a password. This account was created as an administrator account. This is the account that you now use.

    I also suggest that you plan ahead a little by creating, testing and documenting an alternative admin account, even though you have a spare House key. This will save you a lot of trouble. Relying on your memory is clearly insufficient.

  • Print issues with old photos scanned .jpeg prints too large & can't print in black & white

    I have a bunch of old photos & scanned articles of a scanner flat of maybe 10 years ago or not.   These are all .jpeg files.

    First of all, when I print on the Windows Live Photo Gallery, they are all print in color, no matter if I change my printer settings or if I go in settings in Windows Live Photo Gallery and deselect color.

    Secondly, not printing in black & white, they all print out extra large and therefore do not fit on an 8 1/2 x 11 pages.  All this elements analysed in years were roughly between 3 "x 5" until maybe 8 'x 10'. "  The fact is that they don't print as I would like.

    One last question, is that I have a newspaper article large .pdf format.  I printed it weeks and had no point of color above.  But I printed this on paper 11 "x 17".pdf file.  She printed on the entire page, but it was stopped at the bottom of each printed page, and I don't understand why.  Which certainly confused me.  Any suggestions?  My plan was to save the pages together to view the log what it was.  It's pages of the newspaper of 1886.

    Thank you

  • Can I subscribe to two simple applications in creative cloud rather than getting the entire suite?

    I have a subscription for first, already, but really just need an extra subscription for Photoshop. I can subscribe to two apps? I'm thinking that might save me $10 a month, rather than getting the CC range.

    Yes, you can.

    I suggest with the Plan of photography for $10 / month. You do not have to use Lightroom.

    Then it will be $30 / month (first + photography Plan) instead of 50 $par month for all applications.
