VMotioning large VMs (8 vCPUs / 128 GB RAM) - Downtime of multiple minutes?

Hi,
when doing a vMotion for a high CPU usage / high RAM usage VMs, could it really happen that there is a downtime (while the VM is paused) of 5-10 minutes during the vMotion process of moving the VM from host A to B?
I am aware that there needs to be a short pause to copy the final memory delta, the CPU registers and to resume the VM, but normally that should take seconds, at most. I was attending a discussion and some people told me they frequently experience outages of 5-10 minutes when vMotioning very large VMs. The ESXi hosts in discussion have 2 CPU sockets, 8 cores each, 396 GB RAM, 2x 1 GBit dedicated user LAN NICs, 1x 1GBit dedicated for vMotion LAN.
Can anybody comment / share their experience on a) if downtimes of 5-10 minutes can really happen b) if there are common misconfigurations?
Thanks.
Best regards,
Andreas

Welcome to the Community - In ten years I have never seen a pause longer than a few seconds even with a large VM -It works that well

I upgraded to 16 mb of ram and after 10 minutes my computer freezes, and ideas? I have an imac mid 2011 21 inch.

Cause and effect points to out-of-spec memory.
Run Apple Hardware Test. Run the extended tests.

If it fails the memory tests, remove the memory and re-seat it. The sockets are very "tight". Run AHT again.
If it still fails, replace your original memory. If it works, you found the problem. Buy Mac memory from Crucial or OWC / MacSales.

Best Browser and OS for G3 Indigo Clamshell w/128 Megs Ram

Hey Everyone,
I am buying an Indigo G3 w/128 megs of ram that's running OS 9.2 and already has some version of MS Office on there. It's never been used on the net at all! All I want to do is e-mail, web surf, and maybe run iTunes. I am also scavenging an airport card from my dead G3 white laptop( Pismo?) and putting that in later, as my girlfriend has a wireless router. Basically, its just a cheap solution as I am working with her at her business and need something inexpensive to work on...that is MAC!
So, my questions are:
1) If I just plug it into an ethernet cable, will it update the firmware?
2) Can I still efficiently use 9.2 with my above described needs( minus iTunes...I know that needs OSX)?
3) What browser could I use and how do I get it if this thing has never been on the net before?
Thanks everyone!

Probably the best browser for OS 9.x is Mozilla. Although Mozilla will have a problem on some web sites that are designed for newer browsers. Download Wamcom's Mozilla browser at: http://wamcom.org/latest-131/ With only 128MB RAM, you need to have a lot of Virtual Memory.
You only need to update the firmware if you are going to install/run OS X.
Although I have Panther installed on my G4, I run in OS 9.2.2 more than Panther.

128 MB Ram and Puma, Tolerable???

On a G3 Imac, 500MHZ with 128mb RAM, is puma going to be suitable for running safari and using appleworks? Should I upgrade to 512? All I need it for is the internet and appleworks. Will puma be good enough, or am i Going to need Jaguar, Panther or Tiger?

Could firefox be installed if Safari isn't?
All I need it for is the internet and appleworks. Will puma be good enough, or am i Going to need Jaguar, Panther or Tiger?
The latest version of Firefox will work with OS X 10.2 (Jaguar). You'll want at least this version of OS X to run a current, modern browser. Although IIRC older versions of firefox (1.5) run in 10.1 so for the absolute basics you could get through.
To answer some of your questions from the other thread:
is Puma even bearable? Is the interface anything like tiger, does it have a dock? Do u have to go into finder to open APPS.?
There is a Dock and Finder. The finder is significantly different than found in 10.3 or later though. You can see a screenshot of the desktop:

Ram previewing with multiple cameras

Hello
I'm a motion newbie...trying to ram preview a 10 second project with 2 cameras, a dolly cam and a sweep cam. The ram preview works for the dolly cam but when the timeline switches to the other camera it's obvious from the frame rate that that camera's view has not been processed into ram.
If I just Ram preview the sweep cam, which lasts for the remainder of the project it renders fine.
Thanks

I tried to replicate the problem but wasn't able to. DId you try a restart? Also, you might try copying all your project contents and pasting them into a new Motion project. If your project file is corrupt, this might help.

Satellite A210-128 swichting-off after about 30 minutes

Hi, I have a problem with my notebook A210-128, it switches off after about 30 minutes of working and after it does not start for about 3 minutes.
When I play some new game in high details it switches off faster. I assume that it can heat up, because the base of my notebook becomes hotter quicker than it was before.
How can I check the temperature of my processor to exclude this reason or is it something else?
Please help.

Hi!
The notebook gets too hot and so it turned off by itself.
You should always ensure that there is enough free space around the notebook. This is important for good air circulation.
So dont use a notebook in bed, couch or something else because this not good for the air circulation.
In your case I would clean the internal cooling fan. You dont need to disassemble anything. To clean use compressed air spray and could blow away the dust from the cooling ventilator.
If it doesnt help you should go to an ASP (authorized service provider) and let check your notebook.
Bye

Information on Essbase License

Hi All -
I'll need some help understanding the Essbase licensing for system 9.3 & 11. I'll talk to an oracle rep on this soon, but before that I want to make sure that I understand it correctly. Any input on this would be highly appreciated.
fyi, I am not a typical infrastructure guy. I was recently invited to a client team & am trying to find out the existing licenses on the essbase server.
They are running 9.3.1, and I don't see any licensing information (nothing like .lic file, nothing in essbase.cfg folder, nothing like license directory under hyperion). When I looked at one of the xcp files in that server, I see that:
Serial Number: bbbbbb
License Expiry Date:
Port Count: 0
Ports In Use Count: 0
1. Does it mean that 9.3.1 doesn't require license file anymore? Any busniess org can use essbase 9.3 without having licenses?
2. Also, I know there is master license file in oracle website for essbase, do we need to download it in case there is no license file in server?
Now, if we want to upgrade the same v9 system to v11, I believe we must purchase licenses for every server.
3. If our server 2 CPUs X 6 cores = 12 VCPUs & 128 GB RAM; that means we need to buy essbase licenses for 6 CPUS. Is that correct?
4. If we have 200 users, how many ports or licenses we need to buy? Is the essbase license based on number of users or number of CPUs?

I hope this is the information you are looking for. I have responded based on my experience, but your situation may be different. Please check and verify with your Oracle sales rep before you do anything.
1. Does it mean that 9.3.1 doesn't require license file anymore? Any busniess org can use essbase 9.3 without having licenses?
There is no license file anymore in V9.3.1. All business organizations need license to use Essbase. I think Oracle software is free to download and learn for individuals or students on a non-commercial basis. Please read the Oracle agreement when you download software. All commercial use will have to be licensed.
2. Also, I know there is master license file in oracle website for essbase, do we need to download it in case there is no license file in server?
You do not need license file.
Now, if we want to upgrade the same v9 system to v11, I believe we must purchase licenses for every server.
3. If our server 2 CPUs X 6 cores = 12 VCPUs & 128 GB RAM; that means we need to buy essbase licenses for 6 CPUS. Is that correct?
Please use the Oracle core conversion factor table to decide if you need to buy licenses
http://www.oracle.com/us/corporate/contracts/processor-core-factor-table-070634.pdf
for example if your current licensing is on Intel Xeon Series 56XX with 8 CPU's (2 CPU x 4 cores) then you are effectively licensed for 8*0.5 = 4 core licenses. I dervied the 0.5 value from the core factor table.
The upgrade is part of Oracle on going maintenance so the licensing rules are still the same irrespective of the version you are in.
When you upgrade if you install on a Intel Itanium Series 95XX with 12 CPU's (2 CPU x 6 cores) then you have to buy additional 8 core licenses.
Licenses Needed = 12 * 1(core factor for Itanium) = 12
Licenses you already have = 4
Additional core Licenses you need to get = 12 - 4 = 8
We had an external third party licensing company help us understand all of this. You may want to hire somebody.
4. If we have 200 users, how many ports or licenses we need to buy? Is the essbase license based on number of users or number of CPUs?
It depends - licenses can either be by server cores or by users. If your licensing is by server core licenses then number of users does not matter. Please check with your Oracle rep or your vendor management on what type of licensing you have. For example one of our regions the licensing is by users and other regions it is by Server Cores.

Spot Healing Brush Content-Aware SLOW! on large files

I updated from Photoshop CC to CC 2014. When working with ultra large format scans (more than 3 Gigapixel) the Spot Healing Brush set on Content-Aware takes unusually long (5-7 seconds for retouching small dust spots). In Photoshop CC the same Content-Aware Spot Healing Brush actions were executed instantly without any perceived delays once I've pointed a source for the Clone Stamp tool (which I found weird but doing so really made the Spot Healing Brush faster on large files). On smaller images it's still very fast on CC 2014 but not on the 3.5 GPixel images I'm working on at the moment.
I know there have been some changes/improvements for the Content-Aware tools but in this case it's seriously hitting the performance. I haven't noticed any other slow-downs in processing performance with the update.
I'm working on a dual-CPU (2 x 2.4 GHz 6-core) and 128 GB RAM Windows 8.1 machine. I've allowed Photoshop to use up to 120 GB RAM.
Is there any way to reset the Content-Aware Spot Healing Brush to work as fast as it had before the CC 2014 update?

My performance settings are the same for CC and CC 2014.
I assume the problem is introduced by the changes/improvements of the Content-Aware tools and on normal file sizes it might not matter for the user if the operation takes 25 or 200 ms. But on large files it seriously slows down the retouching work.
So far I've been doing as you suggested, using CC for that type of work. But as it takes about 90 minutes to save these huge files and AFAIK Photoshop CC and CC 2014 cannot be run as separate instances simultaneously it's quite inconvenient not being able to use CC 2014 for some other type of work while CC is saving the file.
If the new Content-Aware functions take that much more processing it would be great to have a choice (similar to the choice of the RAW-engine used in ACR). However, if the new Content-Aware functions are just not yet optimized for fast performance then it's a bug.
I will file a Feature Request/Bug Report and ask if there is anything that can be done about it in Photoshop CC 2014.
Thanks for your help, Eugene.

How much ram,etc.??

Friends -
I am running OS10.4.6 on 384 mb sdram. mostly all works satisfactorily.
occasionally when I transfer photos or certain graphics into MSWD I get the spinning wheel and have to force quit and start over.
I also get the wheel on occasion elsewhere but almost always resoves within seconds.
I have read many different suggestions including that 384 is fine, 512 is better but no more needed, all the way up to suggesting 1gb.
I thought I had one port left, but about this Mac says I have DIMM0/J21: Size:128MB; DIMM1/J22: Size:256 MB; DIMM2/J23: Size: Empty; DIMM3/J24: Size:Empty so do I have to ports left?
Your thoughts appreciated on these two questions?
thanks.

Mostly it depends on what sort of applications you use, how many processes you have running, etc. There's really no magic number. For some 2 GBs isn't enough while for others 512 MBs is more than adequate.
In my opinion I would not recommend using OS X with less than 512 MBs of RAM.
If you want to try and gauge your memory needs then after using your computer for several days take a look at the Pageouts and Pageins and size of your swapfile(s). You can open the Terminal and at the prompt enter "top -S" and press return (omit the quotes.) In the top part of the displayed output you will see two sets of figures that may look like this: 100993(0) pageins, 173314(0) pageouts. The values in the parentheses are the important figures. If the one for Pageouts is not zero (0) then that means you don't have sufficient RAM for the processes currently running and the OS has to page out to the VM swapfile. You will also see the size of your swapfile. It will look something like this: Swap: 1.08G + 942M free. Usually OS X allocates swap space in 64 MB chunks first, then 128 MB chunks, then 256 MB chunks as the system demands. If you typically have a large value in the parentheses of Pageouts and also have a large swapfile, then you need more RAM. If the value in parentheses of Pageouts is zero, then you have adequate RAM.
top will also report the information on active, free, and inactive RAM just as Activity Monitor does. Your total available RAM at any time is the sum of inactive and free RAM. If that sum is typically small then you need more RAM or you need to quit some applications.

Updating to Tiger...RAM issue

hi
I only have 128mb of ram in my emac and tiger says you need 256mb.
Stupid question, but if i get tiger regardless of this, will it mess up my emac because i wont have enough RAM?
what would happen if i installed it?
Please reply

hi
I only have 128mb of ram in my emac and tiger says
you need 256mb.
You have a 1st or 2nd generation eMac and never put any extra RAM aboard. You're going to need to increase the RAM. OS X 10.0.x through 10.2.x will run with as little as 80 MB, but won't be happy with less than 192, and really needs 256 to do actual real work. OS X 10.3.x, make that 128, 256, 384. OS X 10.4.x... if you don't have 384 to 512 MB, you're in for a shock. Personally, if I had your eMac I'd add a 512 MB stick to give it 640 MB, or, more likely, just pull the 128 and add two 512s to max the RAM.
Stupid question, but if i get tiger regardless of
this, will it mess up my emac because i wont have
enough RAM?
If you get Tiger to boot in 128 MB RAM it'll be so slow that you'll regret trying. 1st and 2nd generation eMacs didn't have particularly fast hard drives, and Tiger will be hitting the drive for virtual memory and hitting it hard. Worse, as 1st and 2nd generation eMacs didn't have particularly large hard drives either, you will notice the space that Tiger's VM takes up. Back when I had a first generation eMac running 10.2.x, I had first 384 and then 768 MB RAM, and Jaguar's VM, which isn't as voracious as Tiger's VM, ate 2-4 GB of disk space depending on what I was doing and how long the eMac was booted.
what would happen if i installed it?
You'd be sorry. Don't do it. Install more RAM. Crucial sells 256 MB sticks that'll work in 1st or 2nd generation eMacs for $70-80, or 512s for $120-130. There are other vendors who sell RAM for less than Crucial, though Crucial RAM is reliable and really does have a lifetime guarentee. I personally would spring for at least one 512.
The alternative, of course, would be to get a new Mac mini, or, if you can still find one, a 1.42GHz eMac.

HDD/RAM upgrade question - 400 mhz sawtooth

Hello!
My Sister has a Sawtooth G4 - Well, I believe it's a sawtooth anyway. I don't know for sure, so I'll post a bunch of specs:
It's a 400mhz model, early 2000. It shipped with a 10GB HDD, and 128 RAM. I believe it also has a 100 Mbps Ethernet. It has a DVI and VGA monitor video card, but i'm not sure the Video RAM level. It has an internal FW 400 port as well. The internal Airport card is shot - er, maybe the extension.
It has major issues with the system - and it seems to stem from a botched OS 9.2 install. It's running 9.1, but with trouble. For one, I can't open the extension manager. For two, it's slow, and acts funny.
Well, I thought i'd be nice, and try to get the G4 working for my Sister. It seems that it may require an Clean install of OS 9.0. Oh well, I can do that easily enough. However, before I go through all that trouble, I'm contemplating upgrading the hard drive (at least). With only 10GB, it's not very useful for iTunes, Photoshop, or our old OS 9 games - things she'd like to have.
I looked at the specs for the Mac at:
http://www.lowendmac.com/ppc/g4saw.shtml
It takes an 3.5 inch Ultra ATA drive? I've seen those around - and a 60GB drive or so is becoming pretty cheap. (I've seen 80G for under $50) I just figured i'd ask if anyone has tips on what to buy, how to install it, and Particularly if I need any special adapters for the G4. It does have a slot for a second internal HDD. I've also heard that a fast, second internal HDD can overheat the computer - is this a common issue I should be worried about?
The same questions go for the RAM. I'd like to add at least an extra 128MB, but I'm not entirely sure what to get. The above site mentions that it uses PC100 SDRAM in DIMM mode? Hmmm... I'll have to look around.
Please excuse any silly questions, I'm just far more familiar with more current systems, and it's 1 AM
Thanks,
Dan
PS: It looks to have a slot for a floppy drive under the DVD-ROM drive. I have a bunch of files on our OLD PowerBook 5300 that i'd like to move - but I need a floppy drive. Our old external USB floppy drive is.... very dead. The external floppy drives i've seen at stores seem to be pretty expensive, but internal drives are still fairly cheap (some under $30). How hard would it be to find/buy/install a compatible floppy drive? What format would it need to be? If such an upgrade runs over the $40-50 that a new USB drive costs, it's not really worth it.
15" Powerbook G4 (May 2005 ed), iMac DV (9.2.2) Mac OS X (10.4.6) 1G Ram, 192 (iMac)

Wow, thanks again!
I figured out that this is the AGP graphics Sawtooth - not the Yikes model. Where do these names come from?
As per upgrading to OS X - we have a G5 which she can use, and a XP box - which is down with the flu for the third (or fourth?) time. Therefore, the G4 will stay OS 9. She just wants to have a reliable machine that can play DVDs and music, and play some of our old OS 9 games. It's not intended to run any new programs, just the old ones that she can't run now. When I mentioned photoshop - it's a "Limited edition" of version 5.0 - and it's far, far, FAR more reliable on the G4 than on our 2-year-old XP box, despite the G4 running 9.1 with a wimpy 128 meg ram!
The main reason for upgrading the HDD was to make it more practical for games and MP3s - via iTunes 2! It won't play AAC, but it plays MP3s fine. She has at least 8 Gig of music - too much for a 10G drive! (Even half of it leaves precious little expansion room)
I'm watching for a "small" HDD - it seems that our local Fry's is no longer selling anything smaller than 100G - which was $100! Or perhaps they were just sold out at the time. I'll keep an eye out for another sale. In fact, asking my friend for an old drive is a good idea. They have parts from at least a dozen old windows and linux boxes floating around - so they likely have a drive or two. If it's a used HDD, loaded with Windows (probably 95-2000), will it confuse the system before re-formatting?
As per RAM:
I'm quite aware of the lack of RAM. However, I'll have to watch for sales! I'm not aware of any "Mom and Pop" stores close by, although that's a fantastic idea. A PC 133 128 MB card runs $40-50 at the local computer stores, but only $15 at OWC! Therefore, if I don't find suitable RAM locally, I'll order some. I wouldn't mind an extra 256 (or 512) for my iMac either.
Speaking of iMac - I've determined that it's the iMac DV Special ED from March 2000. (400mhz, originally 13 Gig Drive - now 60, 9.2.2) The question is whether or not it maxes out at 512 MB or 1 GB of RAM. One of the Apple support sites I found ( http://docs.info.apple.com/article.html?artnum=58007 ) said that the slot loading iMacs max out at 512. It makes no distinction between any slot loading iMac. However at http://www.lowendmac.com/imacs/dvse.shtml, it mentions that this model specifically can accept 1 gig of RAM. I'll assume that the Apple article is correct, but I'd love to get a full 650 MB if I can! (I'd love to add a 512 to the 128 I have now)
It's amazing, really - after 4 years of constant use, a hard drive motor failure (hence the 60G HDD), and a year and a half burried on a desk, the iMac is becoming more handy by the day. It's good at capturing the Video and audio from say, Halo, while my PB's too busy to run anything else (via S-Video and audio through our DV cam). It makes a great DVD player, an iTunes Jukebox, and game machine - most of my games are still OS 9. To top it off, it makes a great wireless base-station for my Nintendo DS at school, where there's no WiFi! With 30 gig of space left on the HDD, it has plenty of room for whatever I want to do with it. Guess you can "teach and old dog new tricks!'
Well, I guess this means my question is answered for now - once I find the things I need, i may have some more questions, Thanks again!

PDA RAM memory usage

Hi all,
We have created a PDA application running on SAP Mobile Infrastructure 2.5 Service Pack 18 Patch 1 on Windows Mobile 5 and Windows Mobile 2003 SE.
Problem description:
The problem is the RAM memory size. For WM 2003 there is no problem because there are enough PDA's with 128 mb RAM size, but the problem is there is no normal PDA running on WM 5 with 128 mb RAM size. There are only devices with 64 mb RAM.
So we are having some problems with the RAM size, and I want to watch what is in the RAM and I want to see the usage of the RAM easily when I use my application. I can switch to the Settings --> Memory and see the values, but this is not reliable and I only see the usage and not what's in the RAM.
Questions:
- Is there a tool to watch the memory and what's in the memory?
- Can someone give me some information how we can store less in RAM and more in ROM without getting a slower application?
Thanks in advance,
Bart Elshout

hi bart,
had you tried profiling you application? profiling will help you in looking which
portion of the code was consuming a lot of RAM and time.
some common ways to counter heavy application
1) lazy loading
this is very effective in a sense that only the classes required for certain
functionalities are loaded and instantiated. this can be realized by using reflection
and customized class loaders.
2) avoid caching smartsync data
when using smartsync, i don't recommend caching of your syncbo data. the lower
layer already have a cache (esp fileIO).
3) avoid rewrapping if possible
wrapping a syncbo or row into another class will make your class instance bigger.
and caching the fields in it, again will also consume some RAM.
that's only for the part of the data. now you have to consider your UI also. are you
using any UI framework?
regards
jo

Can I add extra RAM on a mini?

This may be a stupid question, but here it goes...
my iBook G3 recently past away (a sad, sad day, I might add), so to save a little money, I decided to replace it with a Mac Mini until I can invest in a new iBook. While I eagerly await its arrival, I was wondering...
Can I install the 128 MB RAM card (that came with my iBook) in the Mac Mini? Not a huge deal if I can't, but I figured since it got erased before the entire hard drive fried, maybe I could still make use of it. Thanks!
iBook G3 Mac OS X (10.3.9)

No. Your Mac mini only has one RAM slot. It will come with 512MB of RAM installed. If you want more, you will need to remove the 512MB module and replace it with a 1GB module. That is the maximum amount of RAM you can install. Here is some info on memory.

Long Project Using too much RAM?

Hi,
I'm running into a bit of a problem that seems to be causing my MBP's 2GB RAM to fill up.
I'm making a really long project containing a lot of audio tracks (it should end up being about 4-5 hours). It all needs to be in one project, and it all needs to be continuous.
I've found that Logic seems be keeping everything (or the vast majority of it) in memory. I seem to be running out of RAM at about 45 minutes.
Is there any way to tell Logic to not hold all of the audio regions in memory? At this rate, even if I put in 4GB of RAM, it's not going to be enough.
Any advice would be appreciated.
Thanks.

Yes this is another large problem I'm dealing with - I have like two GB of ram left on my 200GB/7200RPM laptop HD.
I've tried deleting stuff, but OSX seems to take up a lot of space itself - I don't have much I can remove.
Do you mean that your 200gb hard drive only has 2gb of space left??? If that is the case, I'm surprised Logic, or any other program for that matter, is even opening. I'm a little surprised that you computer is even booting up! You MUST have at least 15-20gb's free, and many users will tell you more. Leopard system files take up maybe 10-15gb, and a full install of Logic is about 45gb. More than 100gb on your drive must be your own data and programs, NOT operating system stuff. Download a program called 'Grand Perspective,' and you can see a graphic representation of your HD and what's taking up so much space.
You need to get an external HD (firewire, and make sure to format for Mac before use), and move a lot of data that you're not using at present. This should improve your performance drastically.
On a side note, having a large number of mp3's in a project will kill performance, because Logic has to decode compressed audio in real time. If you go into the bin, highlight all of your mp3's, aac's, (any compressed audio files), and change them to AIFF's, and that will get you better performance.
But free up some gigs first!!
