High Availability and mac mini

Hi All,
Currently running Mac OS X Server on a mac mini, I'm looking for some ways to make that mac mini "server" a high availability system for my office.
The first thing i will change is to install the operating system on a external firewire 2 disks RAID 1 hard drive : http://www.lacie.com/us/products/product.htm?pid=10967
Then I'm thinking how to make sure the rest of the mac mini will be running all the time as well.
That's why I'm wondering if it's possible to make everything double : 2 minis with 1 RAID hard drive each.
Each complete set would be linked to create somewhat of fail-over system : If one set woes the other one can take over with exactly the same data.
A bit like what it's been done here :
http://homepage.mac.com/pauljlucas/personal/macmini/cluster.html but with OS X Server instead of Linux.

Would this be useful?

  • I need help to take decision to choose between iMac Late 13 and Mac Mini Late 12

    Hey guys,
    I have currently got iMac 27 3.2 GHz mid 2010 and since I am a photographer it unfortunately dosn't meet my requirments at all! It has recently become too slow and that is why I have taken my decision to purchase a new desktop to improve!
    I was intensely awaiting new Mac Mini Late 2013 at Apple 22 Oct event yet no new Mac Mini came up for upcoming year! Now I am very skeptical to choose between to options; iMac Late 2013 and Mac Mini Late 2012! Since having high performance is really essential for me, I am going to tune up my device with 2 Samsung 840 PRO SSD and 16GB RAM to take advantage of the best possible performance.
    Since I can easily utilise my iMac 2010 27" as display for Mac Mini, please instruct me which on I should buy or I have to be more patient for next Mac Mini!
    Thanks in advance!

    I am not sure how you are planning to "easily utilise my iMac 2010 27" as display for Mac Mini" I am concerned that might not work out nearly as well as you might think. I have seen that attempted by others and the results were pretty clunky and could easily wipe out any anticipated speed gains. Be sure and talk to someone who uses an iMac as a display for another computer before you spend any money.
    That said, if I were in your shoes I would either go with a current top end iMac or a maxed out, top end Mac mini and a 27" Thunderbolt monitor. You will end up spending about the same either way. You can save a few hundred dollars buying factory refurbished machines from the online Apple Store or Smalldog.com but you take your choice of what is available and don't expect it to be there tomorrow.

  • Using Time Capsule and Mac Mini to replace a PC.

    I have 4 macs of various vintage in the house and 1 PC. I use the rather robust PC as the server for my itunes library. I'm fully uploaded to iCloud. I'd like to replace this final PC with a Mac Mini but none have a harddrive large enough to accomodate my iTunes library. (about 785G of music and video) Can I use a Time Machine as the storage device for my iTunes library? Can I connect the Time Machine and Mac Mini via Thunderbolt for fast data access? Also, if I can use the Time Machine for storage of the iTunes library, should I consider the iCloud to be my "Back Up" or should I get an additional Time Machine for back up? Also, I use and AirPort Extreme as my wireless router with 2 AirPort Expresses to expand my wifi network. Can I simply add Time Machine to my existing network or will I need to replace the AirPort Extreme with the Time Capsule?

    Don't use Time Capsule for media storage.. it is not suitable and although pressed into service it is a pain. (Time Machine is software backup on the computer and is completely unrelated to the TC).
    The problem with using Time Capsule to Time Capsule, is simple.. it doesn't have any software to do it.. The TC is a backup device.. not a NAS. Do not try and use it as a NAS.
    You can add a TC to the network without doing much.. just bridge the TC and it will work fine plugged into the AEBS.. but again it is expensive waste. You are buying a router with enclosed hard disk drive and turning off the router.. so all you have is a hard disk which is networked.
    If you get a mini use firewire external drive.. you can get 2 or 3 TB fairly cheaply and plug it in. Then back up to a TC if you really want, but any NAS with Time Machine extensions will do the job. Or a hard drive in another Mac made available to the network.

  • Flash (is it for me?), Wacom Cintiq 22HD, and Mac Mini

    I have Flash as part of the CS6 Master Suite, which I purchased primarily for InDesign, Photoshop and Premiere, but as yet I haven't opened Flash. I'm hoping someone here can save me time by advising me whether Flash is suitable for my purposes. I'm not a professional, just a keen amateur, but I do want to use quality software and equipment to do the finest job I can.
    Answers to a previous post in the Illustrator forum (Re: Animation – is Illustrator what I should be using?) suggested that I try Flash.
    Background
    I'll be using Premiere for converting my audio-visuals to HD format. Back in the 1980s I was right into three-screen slide shows. As part of the transforming, I'll be introducing a small number of video clips (hence my need for Premiere) and also short animation sequences, probably 10 seconds at most. The animation will be done by an artist friend who is keen to extend his talents into computer art. If I buy the computer (some sort of Mac), a Cintiq, load the appropriate software, and then loan it all to Steve and show him how to use it, he'll happily spend as much time as required for the animation. We're bartering: he gets to use a computer and tablet for as long as he wants, I get animation.
    A typical animation might involve Steve drawing outlines at appropriate intervals, over a background, then having the software generate the in-betweens. Watercolour-style shading (i.e. not fill-type, monotone colour) would be added, probably manually for each frame, unless the tweening can competently handle watercolour-style shading. For some of Steve's doodlings on his iPad (simplified versions of what we're aiming for), check out http://www.mediafire.com/download/sj731c17co55g5w/Steve's_iPad_Work.zip
    We're both new to this and recently spent an afternoon together looking at videos on Flash and the Cintiq. The combination looks like it will work for us, but I have a few questions which I'm hoping some of the experts on this forum can answer. A simple yes or no may save me hours of reading documentation only to find out that something won't work as I want. I'll also include some questions about the Cintiq and Mac Mini in case someone who uses them with Flash can provide answers. I live in a place where I have no access to these devices before I buy. I have to buy 'cold'. Thus my wariness.
    Please note: I'm not an artist and Steve isn't computer literate. So some of these questions might appear pretty dumb to an experienced user of Flash/Cintiq.
    Ques 1
    Is Synfig Studio (as suggested at the end of my Illustrator thread) something I should consider? Or is Flash a better bet?
    Ques 2
    Does Flash have vector tools that mimic a watercolour paintbrush like in Photoshop? Or is that not possible as a vector, and such effects have to be done outside Flash and then imported as background (or other method)?
    Ques 3
    When a Flash animation is finished, how is it exported, for example, to Premier? Do you export as h.264?
    Ques 4
    It is not clear to Steve and I after viewing three Cintiq videos, how the Cintiq interfaces to Flash. Does the Cintiq know about Flash, and appropriates certain drawing tools automatically? Or do you have to tell Flash (or the Cintiq) that this button on the Cintiq now operates this tool in Flash?
    Ques 5
    Do Flash and Cintiq work well together – and easily?
    Ques 6
    Do I need a monitor to be able to use Flash with the Cintiq? Or would a Mac Mini be a suitable computer – with the Cintiq acting as monitor? Steve won't ever be using this setup as a computer. He'll be treating the Cintiq as a canvas on which to draw and paint.
    Thanks in advance for any replies.

    Hi Guy,
    I thought I was the only one around who was old enough to have worked on wide screen multi-image slide shows!
    Flash may be the right product for you and Steve. I use Flash with an Intuos 4 tablet and it works fine. What you want to do is to search the Flash forums for references to Cintiq. There may be some problems that interfere with your intended use, or it may work exactly as you want. The important element for working with any Wacom product is to be sure that you are using the latest drivers for the Wacom product.
    If you choose to use a mac mini, get a new one, one that can use a lot of memory, you'll need it.
    You can export Flash files to video in most any file type and compression is installed on the computer. So, if you're going to use a Mac, install Quicktime Pro and you should have everything that you need.
    I have never heard of or used Synfig Studio, so I can't comment on that.
    Flash's paint tools are different from Photoshop and more similar to Illustrator's. You will have all of the flexibility of the Cintiq to control painting effects, it will take some practice, but you should be able to get the effect that you're describing.
    Hope this helps with your decision.

  • How to connect a 23" Cinema display and mac mini to an AV Receiver?

    I am trying to get my 23" Cinema display and Mac Mini to a Yamaha RX-2700 AV Receiver. I am on first name terms with the guy in Maplins because I tried to get an Xbox 360 working with this display before and gave up in the end.  The AV receiver has upscaling capability so I thought I'd try again.  I tried connecting a HDMI - DVI adapter to the HDMI Out on the receiver and a HMDI to DVI cable from the Mac Mini to the HDMI in with a optical cable for the sound.  The sound works fine but I get no display - the LED on the monitor flashes three times with a blank screen so it can't read the signal.  Another option suggested was to use a VGA Converter connected to a VGA - HDMI cable but I would like to find out if that would work before going down that route?
    I am looking for some advice about whether this type of configuation is possible with the 23" ACD and if so what do I need to buy to make it work?  I love the quality of my ACD to avoid having to replace it with a TV to get my multi media life in order.
    Many thanks

  • Why is my Internet connection hanging on both MacBook and Mac mini, but not PCs, Xbox, or iOS devices?

    I have a MacBook pro and Mac mini both running the latest version of lion.  I've had this issue with my MacBook for sometime now, but just dealt with it and figured it was isolated, but now I am finding its not.
    Essentially, I will open up safari, or Chrome, and the first few pages will load fine.  Sometimes I will get lucky and be able to browse normally, but after awhile, safari just hangs there and stops loading.  I can close the window, and open a few more pages before it does it again.  Both my mini and MacBook do this, but only on my home network.  My MacBook runs perfectly fine on my work wi if, and other wi fis, so I definitely know its my home modem.  If I wait it out I can surf the Internet again, but this dead time is absolutely killing me. It just randomly stalls, on both computers.
    I current have time Warner cable roadrunner, with a cable modem gateway.  The issue was happening on a straight connection.  I had hoped getting a time capsule and connecting to that network would solve things, but it didn't.  Interestingly enough, my Pcs, Xbox,and all 4 of my iPads and iPhones work just fine on the wifi, so there has to be a communication issues with the MacBook and mini with the cable router.
    I've tried messing with lions network DNS servers and tried opendns ones, but those didn't work.  Sometimes I can fix the problem for a few hours by power cycling the modem and router, but I shouldn't  have to do that over and over every time it's an issue.  I've also tried removing and adding the wi if connections, but that.works for a minute or two and then the problem resumes.
    Now, I have my time capsule connected to the gateway, and tuned the time Warner modem wireless off, which didn't help of course, but at least I'm properly backed up.
    I'm not sure what the issue is.  I've even tried typing an ip address of apple during a dead time to see if that worked and didn't.
    Does anyone have any other ideas?  I'm pretty much at my wits end in this, any ideas would be greatly appreciated

    Have you tried a simple reset of your iPod to see if that helps?  To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
    Otherwise, have you tried any of the troubleshooting mentioned in this Apple support document?

  • If i have multiple iPhones and Mac Mini sharing the same Apple ID, can I use Facetime between the devices?

    if i have multiple iPhones and Mac Mini sharing the same Apple ID, can I use Facetime between the devices?

    Yes, but if you want these devices to have complete capability of calling each other they each must have their own separate, individual e mail address.  If they don't have individual e mail addresses, the i phones will be able to call each other because you'll be using their  individual phone numbers -- the Mac mini will be able to call the i phones, but, the iphones will not be able to call the Mac mini.  This is because the iphones will be using the mini's e- mail address to make the call, and if they have the same e mail address, they will think they are calling themselves, so the call will not connect.
    So, the way I see it is,  if you keep all of the email addresses the same, the only thing you'll loose is the ability of the iphones to call the mini.
    EDIT:  Thinking about it, my first sentence needs to be modified.  Your iphones can share an email address but it must be different from the Mac mini address.
    This isn't rocket science, but it can make your head spin. LOL

  • The PDF file and slideshow view corrupted using iPhoto. Macbook air only get corrupted slideshow and Mac Mini both slideshow and PDF file is corrupted.

    The PDF file and slideshow view corrupted using iPhoto. Macbook air only get corrupted slideshow and Mac Mini both slideshow and PDF file is corrupted.

    Saving as a PDF file for some users have been a problem.  If you boot into  Safe Mode and run iPhoto you can create undamaged PDF files.  We don't know why the problem but this is a workaround.
    This problem prevents many from ordering books, calendars and cards since iPhoto creates PDF file of them for uploading and printing.  Booting into Safe Mode lets them successfully order those items.

    Thank you.

    Hi,
    You can serially cluster two WAE devices with the Cisco WAE Inline  Network Adapter installed to provide higher availability in the data  center if a device fails. If the current optimizing device fails, the  inline group shuts down, or the device becomes the overloaded, the  second WAE device in the cluster provides the optimization services.  Deploying WAE devices in a serial inline cluster for scaling or load  balancing is not supported.

  • Any help with a Time Capsule install and Mac Mini server screen share?

    Installed a Time Capsule, now I can't access my mac mini server.  I see the files/folders, but cannot screen share with the mini from my macbook pro.  Any help?  Error below when trying to use the "screen share" button in Finder.  Macbook Pro and Mac Mini are using Mountain Lion 10.8.2.
    Connection Failed Error: Please make sure that Screen Sharing (in the Sharing section of System Preferences) is enabled on the computer to which you are attempting to connect. Also make sure your network connection is working properly.
    Please help, I'm really stuck on this one!

    Try removing the TC and see if the problem disappears.
    Screen Sharing has a checkered histroy looking back through the posts..
    https://discussions.apple.com/message/16026896#16026896
    There are many discussions about failing after changes in Lion.. I haven't seen the equivalent ML yet.. the TC may not be root cause, just the initiator of the problem.
    It could be the BTMM associated with the TC.

  • SQL Server 2005 High Availability and Disaster Recovery options

    Hi, We are are working on a High Availability & Disaster Recovery Planning solution for an application database which is on SQL Server 2005. What different options have we got to implement this for SQL Server 2005 and after we have everything setup how
    do we test the failover is working?
    Thanks in advance.........
    Ione

    DR : Disaster recovery is the best option for the business to minimize their data loss and downtime. The SQL server has a number of native options. But, everything is depends upon your recovery time objective RTO and recovery point objective RPO.
    1. Data center disaster
    Geo Clustering
    2. Server(Host)/Drive (Except shared drive) disaster
    Clustering
    3. Database/Drive disaster     
    Database mirroring
    Log shipping
    Replication
    Log shipping
    Log shipping is the process of automating the full database backup and transaction log on a production server and then automatically restores them on to the secondary (standby) server.
    Log shipping will work either Full or Bulk logged recovery model.
    You can also configure log shipping in the single SQL instance.
    The Stand by database can be either restoring or read only (standby).
    The manual fail over is required to bring the database online.
    Some data can be lost (15 minutes).
    Peer-to-Peer Transactional Replication
    Peer-to-peer transactional replication is designed for applications that might read or might modify the data in any database that participates in replication. Additionally, if any servers that host the databases are unavailable, you can modify the application
    to route traffic to the remaining servers. The remaining servers contain same copies of the data.
    Clustering
    Clustering is a combination of one or more servers it will automatically allow one physical server to take over the tasks of another physical server that has failed. Its not a real disaster recovery solution because if the shared drive unavailable we cannot
    bring the database to online.
    Clustering is best option it provides a minimum downtime (like 5 minutes) and data loss in case any data center (Geo) or server failure.
    Clustering needs extra hardware/server and it’s more expensive.
    Database mirroring
    Database mirroring introduced in 2005 onwards. Database Mirroring maintain an exact copy of a database on a different server. It has automatic fail over option and mainly helps to increase the database availability too.
    Database mirroring only works FULL recovery model.
    This needs two instances.
    Mirror database always in restoring state.

    HADR Considerations
    Need to Understand the business motivations and regulatory requirements that are driving the customer's HA/DR requirements. Understand how your customer categorizes the workload from an HA/DR perspective. There is likely to be an alignment between the needs
    and categorization.
    Check for both the recovery time objective (RTO) and the recovery point objective (RPO) for different workload categories, for both a failure within a data center (local high availability) and a total data center failure (disaster recovery). While RPO and
    RTO vary for different workloads because of business, cost, or technological considerations, customers may prefer a single technical solution for ease in operations. However, a single technical solution may require trade-offs that need to be discussed with
    customers so that their expectations are set appropriately.
    Check and understand if there is an organizational preference for a particular HA/DR technology. Customers may have a preference because of previous experiences, established operational procedures, or simply the desire for uniformity across databases from
    different vendors. Understand the motives behind a preference: A customers' preference for HA/DR may not be because of the functions and features of the HA/DR technology. For example, a customer may decide to adopt a third-party solution for DR to maintain
    a single operational procedure. For this reason, using HA/DR technology provided by a SAN vendor (such as EMC SRDF) is a popular approach.
    To design and adopt an HA/DR solution it is also important to understand the implications of applying maintenance to both hardware and software (including Windows security patching). Database mirroring is often adopted to minimize the service disruption
    to achieve this objective.
    HADR Options :
    Failover clustering for HA and database mirroring for DR.
    Synchronous database mirroring for HA/DR and log shipping for additional DR.
    Geo-cluster for HA/DR and log shipping for additional DR.
    Failover clustering for HA and storage area network (SAN)-based replication for DR.
    Peer-to-peer replication for HA and DR (and reporting).
    Backup & Restore ( DR)
    keep your server DB backups in network location ( DR)
    Always keep your sql server 2005 upto date, in case if you are not getting any official support from MS then you have to take care of any critical issues and more..

  • How to configure high availability and disaster recovery? And user authenticate

    We are in the process of rolling out our online help which was created using Robohelp.   In our initial rollout we will provide access to the files via our Client Portal which requires authentication.  We are also planning for our next version where we intend to implement Robohelp server functionality.
    Our IT team is looking at options on how to configure for High Availability and Disaster Recovery.  It seems that Robohelp doesn't have any built-in functionality in this area.  In addition we require that our users authenticate.  The options for the server version seem to be more internally focused and we would need to solution the authentication using a third party.
    Would anyone be willing to share their approach in these areas?  Would you be willing to participate in a conference call with our IT Professionals?

    Hello again
    I see my good friend Peter replied to your LInkedIn post where you cross-posted the same question. For those here that have no clue what Peter stated, here it is:
    What are you seeking to recover? Your projects? Your outputs? This sounds like a question more appropriate to Disaster Recovery consultants and far wider reaching than RoboHelp. To me it seems like a question your IT people should be asking direct to such consultants who would expect a fee for their advice.
    I would agree with Peter's reply.
    I'll also go further and ask what exactly is being done in this realm for the application? Help files generally are there to support an application on the server. So whatever you are doing for the applciation should also be able to be used for the WebHelp, FlashHelp or web based AIR Help files, no?
    Cheers... Rick
