Suggestions for [cheap and temporary] mirrored SAN for vSphere

vmware vsan is an option but you'd need a 3rd host.

I am researching potential upgrades to a system currently used for corporate events/roadshows, which need to be very resilient, but relatively cheap as only used for a few weeks/months at a time.
Existing system uses dual ESX hosts in a HA cluster, using a shared SAN. Almost everything is duplicated and redundant - both hosts and SAN have dual power supplies, coming from different power circuits. Each host has multiple NICs connected to different management and iSCSI switches on the different power circuits. SAN has multiple volumes on different disk arrays on different iSCSI channels. Whole lot is backed by UPS.The one single point of failure, is the SAN. We have single physical box due to cost. I can't be sure if it's multiple controller (haven't checked). If the SAN hardware catastrophically fails, we're game over.We've thought of...

  • Cheap and temporary screen fix.

    Found this article on Digg for those who don't have the money to shell out for a broken screen. It's time consuming and should be considered a temp fix but may get you by.

  • Suggestions for Cable Modem and Wireless Router

    Hey everyone!
    I have the new iMac and would like to have a faster wireless router. Currently using an old D-Link Wireless G router and would like something like the Time Capsule (as it has Airport Extreme in it) or Netgear Rangemax Dual Band Wirless-N Gigabit Router. My problem is, my Internet is through my cable company, so it comes into the house as a cable connection. It appears that these two combos would still require the use of a cable modem.
    Any suggestions to keep the equipment down to one piece? If not, any suggestions for a cable modem so I can return this old one to the cable company?
    What would be the best/quickest wireless router?
    Thanks for your help!

    Go to your ISP's web site and do a search from your ISP for compatible cable modems. Then buy the capable modem your ISP says that is comp[atible. On the new cable modem find the Serial number & MAC address, make then call your ISP tech help desk and tell them the new modem you got and he/she will ask you that information. When the ISP tech says they can see/ping that new cable modem then it will work. Then connect a new cheaper Airport Extreme and any external USB2 hard drive to connect to that new Airport Extreme. I say this because Apple put out and Update a little while ago that will allow an external connected to an Extreme as a Time Machine disk.
    PS: Remember the old trick of checking you Ethernet cables. I can't count how times I have seen professionals install all new high speed switches, routers, etc. and wonder why no speed is seen. Then after numerous trouble shooting they discover they used the old 10 Base T cables and just changing the cable solved their problem.
    Just make sure you do this one at a time starting with getting the ISP compatible cable modems list to know what cable modem you can buy (to save that monthly ISP rental fee). Then you can get the going as long as so speak with your ISP tech to give them that new cable modem Serial number and MAC address so they can register it with their servers.
    This will be to easy as long as you do things in step.

  • HT1338 My Mac book Pro is running very slow and the rainbow ball is appearing all the time. Any suggestions for clean up??

    My Mac book Pro is running very slow and the rainbow ball is appearing all the time. Any suggestions for clean up?? I have the OS X Lion system.

    As well as what a brody asked :
    - do you need more RAM? (run Activity Monitor and see how much free RAM - green - is available)
    - do you Restart fairly regularly, e.g. at least once a week, to clear out any swap or temporary files?
    - do  you need to do maintenance, e.g. clearing out caches and unused logs, etc?

  • Suggestions for creating LOGOS and GRAPHICS??

    I create logos as kind of a "hobby". I usually use PAGES to create as most are manipulations of fonts, shapes and importing images, etc.
    I realize I am limited by PAGES in terms of producing high quality images for reproduction.
    Does anyone have a suggestion for the next best program to use? I don't have the patience or time to learn COREL DRAW - I'm hoping there is something in between PAGES and programs similar to COREL!
    SUGGESTIONS are really, really appreciated!
    Thank you.

    I do monograms in Photoshop Elements which is really a program for photo manipulation but is a great program for graphic design. I went with Elements since it is a lot cheaper than the full version of Photoshop and has everything I need.

  • I cannot send an email from my iPad 2? No problem receiving, why does this happen? Have tried the suggestions for setting up email and after doing the sync mail through iTunes receiving worked great but still cannot send? Any help would be great

    I cannot send an email from my iPad 2? No problem receiving, why does this happen? Have tried the suggestions for setting up email and after doing the sync mail through iTunes receiving worked great but still cannot send? Any help would be great!

    The fact that you can receive means you have a valid e mail address, and have established the connection to the incoming server, so all of that works.  Since the send does not work, that means your outgoing server is rejecting whatever settings you used formthe outgoing set up.  Try them again. 
    Google your particular isp, and ipad and many times you will find the exact settings needed for your isp.  Or tell us here, and soneone else may be on the same isp.  Some mail services need you to change a port, or have a unique name for the outgoing server.  
    Kep trying.

  • Is there an EASY way to submit podcasts to the itunes store? i've tried creating podcasts in garageband, then somewhere after wordpress  itunes  doesn't recognize the feed. my process has been (i am open to suggestions for other free and EASY services/me

    is there an EASY way to submit podcasts to the itunes store? i've tried creating podcasts in garageband, then somewhere after wordpress  itunes  doesn't recognize the feed.
    my process has been (i am open to suggestions for other free and EASY services/methods):
    garageband : create & edit audio. add 1400x1400 image.
    share to itunes.
    drag file to desktop.
    upload .m4a file to google drive.
    create a link post in wordpress using "podcast" tag & create "podcast" category.
    click on "entries rss" in wordpress, which takes me to the rss subscribe page (which is basically just my wordpress address with "/feed" at the end.
    i copy this url.
    go to itunes store > then "submit a podcast"
    itunes gives me the error message "we had difficulty downloading episodes from your feed."
    when i try to subscribe to my podcast in itunes, it does, but gives me no episodes available.
    i went back into wordpress and changed settings/ reading settings to : "full text" from "summary"
    still the same error message.
    i added a feedburner step after wordpress but got the same errors. i don't think i should have to add feedburner.
    wordpress seems to be encapsulating the rss, what am i doing wrong?
    this so much easier when you could go directly from garage band to iweb to mobileme; i miss those apple days (also idisk).

    if anyone has a super EASY process, i would LOVE to know what it is. EASY, meaning no html and also free. there are many free online storage systems available, many of which i currently use. the above process was just me trying to figure it out, if you have an easier method, please share. thank you so much!

  • Does anyone have a suggestion for an alternative to iCal that will interface with the Cloud? I find iCal to be poorly designed and not very efficient.

    Does anyone have a suggestion for an alternative to iCal that will interface with the Cloud so it works on the iPhone and the Macbook? I find iCal to be poorly designed and not very efficient. I waste a lot of time entering information because you can't go to a specific day and enter information, nor can you navigate between months and add information on a specific date by clicking on the date. You can't easily scroll month-to-month and once you do by scrolling through nine months to get to where you want to be, you cannot enter information by clicking on a specific day in the month and entering information. I just called Apple and they verified that this is the way it works. You cannot go to a date and enter information, you keep getting thrown back to today and then you have to go into the calendar and change it manually on the screen. It is just not efficient.

    APC, CyberPower are reliable.
    Look for 1500VA. As example:

    Hi Thomas,
    I have had similar considerations and finally chose QNAP 439 Pro II over the many other ones out there (LinkSys, NetGear, Bufallo, etc.). Without going into technical details, the main reason for my choice were easy-of-use, functionalities and scalability:
    http://www.qnap.com/prodetail_feature.asp?pid=148
    It's not the cheapest solution out there, but works great with the Mac, even acts as storage solution for TimeMachine (with latest firm ware). And implementing client access is easy.
    Hope this helps.
    Kind regards,
    Mark

  • My granddaughter put the Start Up Disk in the drive inadvertently and now the drive will not eject it or start up using the HD.  I have tried all of the suggestions for opening it that appear in the manual.  Help?

    My granddaughter put the Start Up Disk in the drive inadvertently and now the drive will not eject it or start up using the HD.  I have tried all of the suggestions for opening it that appear in the manual.  Help?  It is her computer, a iMac G3 or G4 with superdrive, the one with the ball shaped base.   Thank you.

    It's a tray loading drive, there should be a little hole next to it, just large enough for a paper clip.  Stick the end of the paper clip in it and the tray should open.

    What other videos and books are there? that you suggest. for step by step .
    Jeannette

    The various Lynda.com video tutorials are very good, but you have to pay for a description.  The Photoshop User TV podcasts are excellent; there are hundreds of them, and they are free.  They are also what the iPad was invented for.
    The 'You suck at Photoshop' videos on YouTube are both very funny and very instructive. 
    The Scott Kelby books are very good for folk starting out.  The Martin Evening, and the Martin Evening/Jeff Schewe books are as good as they get from a photography point of view.  The Steve Caplin books are the best Photoshop books once you get into it, but Scott Kelby and Matt Kloskowski do some great medium to advanced books.  Matt's Compositing Secrets is excellent, and was Amazon's best Photoshop book for a while.

  • Suggestions for new iMac, hard drive and Thunderbolt vs FW800 vs USB3?

    Ordering a new iMac 27" and leaning toward fusion drive,  and wondering if anyone has any suggestion or experiance with this drive? Any suggestions for drives would be welcome.
    I am going to have to decide what to do as far as storage and I assume USB3 will be the best choice - been using FW800 and lots of new things coming.
    Thanks for any input and suggestions.
    Don

    anybody have any comments on the use of Thunderbolt vs USB3? I am using FW800 not and will be changing my 2 external drives. I have to keep FW800 on them so I am able to daisey-chain them. My use is normal and wondering if I should stay with USB3 & FW800 for external or make the TM drive a Thunderbolt. Those seem to be priced higher just wanted some suggestions, recommendations.
    Thanks,
    Don

  • What is proper way to report suggestions for app features And bugs to Apple

    What is the proper way to report suggestions for app features to Apple? Or, do they even want suggestions?
    And, how about reporting app bugs? Should I just assume the bug is already known, or is there a way for (quickly) reporting them?

    I'm not sure about bugs in non-Apple apps, but bugs in Apple apps can be reported via this form:
