Physical Disk Management for Azure

I'm currently trying to troubleshoot one of my clients Azure environments. I find that the IOPS are significantly slower than my local servers. Is there any information about what kind of physical infrastructure Microsoft is providing for Azure / is there
a way to get hardware isolation?

Hello,
Have you seen the following article?
http://msdn.microsoft.com/en-us/library/windowsazure/dn197896.aspx
As you can read on the above article, the greater the quantity of disks the greater the IOPS you will get. 8 disks x 500 IOPS = 4000 IOPS.
How much IOPS you have on local server? Match that amount to the quantity of disks as explained in the article.
Hope this helps.

Best Practice while configuring Traffic Manager for Azure Website

Hi Team,
I want to understand What is the best practice while we configure traffic manager for Azure website.
To give you the base, Here let me explain my requirement. I have one website which 40% target audiences would be East US, while 40% would be UK and rest 20% would be from Asia-pacific.
Now, What I want is Failover + Performance based Traffic Manager Configuration.
My thinking:
1) we need to create 1 website with 2 instances in each region (east us, east asia, west us for an example). so, total 3 deployment of website. (give region based url for the website)
2) create traffic manager based on performance and add 3 of those instances. that would become website-tmonperformance
3) create traffic manager based on failover and add 3 of those instances. that would become website-tmonfailover
4) create traffic manager and ?? don't know the criteria but add both above traffic manager here and take your final url for end user.
I am not sure (1) this may be the right approach or not (2) if this is right, in the 4th step which criteria we should select while creating final traffic manager round-robin/ performance/ failover?
after all these if use try to access site from US.. traffic manager will divert that to US Data-Centre or it will wait for failover and till that it will be served from east-asia if in configuration, east-asia is my 1st instance?

Hi Jonathan,
Thanks for your quick reply. actually question is bit different. Let me explain you different way.
I was asking for recommendation from Azure Traffic Manager team. whether my understanding is correct or not.We want Performance with Failover.
So, One azure website we have: take an example todoapp. I deployed that in 3 different region. now, I want to have performance based routing as well as failover based routing. but obviously I can't give two URL to my end user. so, at the top of that I will
require one more traffic manager. So,
step 1: I will create one traffic manager with performance criteria named: TMForPerformance.trafficmanager.com where I will add all those 3 instances (all are from different region so, it want create any issue.)
step 2: I will create one more traffic manager with failover criteria named: TMForFailover.trafficmanager.com where I will add all those 3 instances (all are from different region so, it want create any issue.)
step 3: I will create one final traffic manager with performance criteria named: todoapp.trafficmanager.com where I will add these two traffic manager instead of 3 different region's website.
Question 1) Is it correct structure if we want to achieve Performance with Failover or Is there any better solution?
Question 2) in step 3, what criteria we should select? performance/ round robin/ failover

Maximum disk size for azure site recovery

Hi everyone,
I am looking into Azure Site Recovery, and I can't seem to find the maximum disk size I would be able to replicate into Azure. I have read some articles saying that 1TB is the maximum size, and some people have said that it is 64TB!! I have a File
Server that I would like to protect which is 4TB in size, and if the limit is 1TB I think it is very limiting...
Any help would be greatly appreciated.
Many Thanks.

Hello Robert,
The current size limits for a VM replicating to Azure are :
For an OS VHD (the vhd that has the OS Installation) : 127 GB
For a Data VHD (<1 TB)
Is the size of your file server running on a single 4 TB volume?
Anoop KV
Hi Anoop,
Our File Server is currently running on a single 4TB volume. Do I have any options with regards to replicating this VM to Azure using Site Recovery?
Many thanks.

Disk Management for RTMP live streams

Hello,
Can anyone tell me if there is anything similar to DiskManagement functionality (available for HTTP streams) available to RTMP live streams in AMS?
I'm having trouble with INDEX files that are being created for the live+DVR streams (we are serving 24/7 streaming), even though I delete RAW DVR files which are old, INDEX files constantly grow and FMS crashes CPU after few days.
Any suggestions are appreciated.

Hi,
The methods that are mentioned as missing as expected by FMLE as it makes calls to them. They are defined in the sample live application that comes with the installation. The code for these can be picked up from the samples folder under the FMS installation from the application live. You can add these in all of your server side scripts to make them more relevant.
Thank you !

Preferred Disk Management for Rendering

I use a 7200 rpm 320GB HD connected via a Firewire 400-800 cable to store media files. I find little difference in render times between rendering back to the External HD vs. the 5400 rpm Internal drive. Is there a preferred method? Thank you!

AppleMan1958 wrote:
The bottleneck in rendering in the processor.
In terms of only DV rendering - you right. I mentioned in general.
When big video file (ex. 12Gb) copied from ext. FW of USB drive CPU load is very high.
The lowest CPU load is when working with SATA. It means system is missing that CPU resources for rendering.

Is it possible to do Continuous deployment for azure cloud services(website,web and worker roles) using VSO Release management?

Hi,
I am trying to do continuous deployment using visual studio online and release management for Azure cloud services. But not able to find the way to do it(with the help of different blogs, those are describing using VM only).
I tried using Release management visual studio extension also. But no Luck.

How to map ASM disk path to physical disk on AIX?

Hi Everyone,
I am working on a plug-in for Oracle Enterprise Manager 10gR2 on AIX 5.3 which provides monitoring of storage arrays and supports ASM databases in addition to the 'emrep' database. One of the metric of that plug-in is populated by the result from a korn shell script. The script directly runs on the AIX host (connected to the storage array by FC cables via HBA ports) and retrieves the mapping for -- Physical disk - Logical Disk - LUN - ASM Disk.
Now, I was able to get the mapping for Physical Disk – Logical Disk – LUN, but could not map ASM Disk. I googled a lot for any clue but did not find the answer to this specific problem.
Now, I have the list of physical disks used for ASM by the command—
lspv
hdisk0 0001c22ac8d664ca rootvg active
hdisk1 0001c22aa51f496a Oracle active
hdisk2 0001c22ac478263a scratch active
hdisk3 0001c22ac472549a Oracle active
hdisk4 0001c22ac4725d6a Oracle active
hdisk5 none None
hdisk6 none None
hdisk7 none None
hdisk8 none None
hdisk9 none None
hdisk10 none None
hdisk11 none None
hdisk12 none None
hdisk13 none None
hdisk14 none None
hdisk15 none None
hdisk16 none None
The disks hdisk5-16 are ASM disks and there are no PVID’s present.
I also have the list of ASM disks by the command—
ls –l /dev | grep oracle
crw-rw---- 1 oracle dba 22, 6 May 12 00:02 asm_rd10_1a
crw-rw---- 1 oracle dba 22, 10 Apr 21 07:27 asm_rd10_1b
crw-rw---- 1 oracle dba 22, 7 May 09 13:53 asm_rd10_1c
crw-rw---- 1 oracle dba 22, 8 May 09 13:53 asm_rd5_1a
crw-rw---- 1 oracle dba 22, 4 May 12 00:02 asm_rd5_1b
crw-rw---- 1 oracle dba 22, 9 Apr 21 07:28 asm_rd5_1c
crw-rw---- 1 oracle dba 22, 12 May 12 00:02 asm_xbb2_rd10_1a
crw-rw---- 1 oracle dba 22, 11 Apr 24 07:34 asm_xbb2_rd10_1b
crw-rw---- 1 oracle dba 22, 13 May 09 13:53 asm_xbb2_rd10_1c
crw-rw---- 1 oracle dba 22, 16 May 12 00:02 asm_xbb2_rd5_1a
crw-rw---- 1 oracle dba 22, 14 Apr 24 07:34 asm_xbb2_rd5_1b
crw-rw---- 1 oracle dba 22, 15 May 09 13:54 asm_xbb2_rd5_1c
Now I am looking for a way to map these two lists with each other, and had no luck so far.
Does oracle provide this information somewhere in the OEM installation structure or is there a command in AIX which could give some way to map the ASM disks to the physical disks?
Any help on this is greatly appreciated. Thanks in advance…
FYI: ASMLib driver is not present on the system.

The view you are talking about here gives the ASM DISK NAME (like DGRXBB_0001) and ASM DISK PATH (like /dev/asm_rd_10_1a) and I am already using it, but this is not what I asked in mt original post. If you read carefully, I want to establish a mapping between the ASM DISK PATH (like /dev/asm_rd_10_1a) and the AIX Physical disk (like /dev/hdisk5) and did not find any view giving this info. If you know of some views which could help establish this mapping or some AIX commands or files that could help do this using shell script, it is most welcome

thanks for your prompt response.
I am aware of that we can't use any free spaces where the VM is installed.Hence the additional storage added to the server.
1. Install VM Server on 80GB HD ( /dev/sdb)
2. Later, i added 500GB to the storage ( no installation - just the disk ) ( /dev/sda)
Same configuration worked fine in 3.0, now i am not able to identified the additional disk which was added later with 3.2.1.

Linux LVM (Logical Volume Manager) for CentOS on Azure?

Hi. I am trying out Azure and installed a OpenLogic CentOS 6 virtual machine. I note that it is not running LVM (Logical Volume Manager) by default. I would like to ask if it is possible to:
1. have CentOS Linux installed with LVM by default when creating a Linux virtual machine on Azure
2. switch to LVM after adding a new disk
On the other hand, is it a good idea to use LVM at all? Will it affect performance, features on Azure?
Thanks.

Hi,
Based on my experience, you can add disk to an Azure VM. You can install the Logical Volume Manager to manage the disks attached to the VM. In addition, there is no Linux VM with LVM installed by default. If you want to have this, please submit your requirement
in Azure feedback:
http://feedback.azure.com/forums/34192--general-feedback
In addition, since you can have only one OS system disk for an Azure VM, this limitation may make multi-disk logical volume manager setups unworkable.
Best regards,
Susie

Physical Disks in StorEdge 3320 not visible in CLI Manager

Hello,
After installing the CLI manager on Solaris 10 for x86 platforms, I was able to connect the server to the StorEdge array. However, I cannot see the 6 physical disks that are in the array. The LEDs on the physical disks are green, but there is just no communication between them and the CLI manager. Could this be a bad controller card? What else could it be?

Physical disk for OS and read only filesystem after live migration

I am running OVM 3.1.1 connected to an EMC storage array. I have a situation where physical disks are being used for OS and binary filesystems (i.e. /u01, etc..) rather than virtual disks inside a repository. When a VM is migrated from one host to another, I sometimes get a message stating the size of the disk changed and shortly afterwards the filesystem is changed to read only and I have to reboot to fix the problem. Is this an unsupported configuration or do I have potential problems with my LUN mapping? Has anyone seen this problem before?

"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." Trying to format my iomega external HD for use with Mac

Hi. Trying to connect iomega ext. HD. i have to reformat for Mac. When i plug in & go to Disk Utility,the external shows up and i'm supposed to click "partition". When i do, a box comes up saying ""Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." I quit and relaunched, same results. After googling my question, i came up with this:
"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility."
(Quitting and reopening Disk Utility does not help.)
The following also appears in Console log:
*** malloc[419]: Deallocation of a pointer not malloced: 0x290a410; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug : for architecture i386 object: ./Applications/iTunes.app/Contents/MacOS/iTunes malformed object (unknown flavor for flavor number 0 in LC_UNIXTHREAD command 27 can't byte swap it)
Workaround
Quit Disk Utility.
From the Finder's Go menu, choose Go to Folder....
Type the following, then click OK: /Library/Receipts
Temporarily remove these iTunes receipts from /Library/Receipts (sort the folder alphabetically as a list):
iTunes.pkg
iTunes4.pkg
You can put them on the desktop, for example. Do not remove iTunesX.pkg or iTunes Phone Driver.pkg.
Open Disk Utility and repair disk permissions again.
Quit Disk Utility.
Put the removed iTunes receipts back in /Library/Receipts.
Note: This issue does not affect Disk Utility's verify or repair disk features.
All seemed good, for a moment, until, upon going back to Disk Utility after removing itunes4.pkg and putting on desktop (i did not have itunes.pkg to remove) the same thing was happening. When i highlite my iomega ext. on left of page, disk perrmissions is grayed and does not allow me to click on it. Same problem from the start. Can somebody please help me out here? That would soooo awesome. Thanx!

i'm just scared i will do something wrong on my own and lose my data.
You shouldn't be scared of that, because you should already have backups. If you don't have backups, then backing up is the first priority.
Insert the Snow Leopard DVD and restart. When you hear the chime, hold down the C key and keep holding it until the Apple logo appears on the display. You should now see the language selection screen. Select your language, then choose Utilities > Disk Utility from the menu bar. In the Disk Utility window, select the external drive (not the internal). The drive may already have a data partition, in which case there will be another icon below the drive icon. Choose the drive icon, then select the Partition tab. Create a single partition with the default options (GUID partition table, Mac OS X Extended Journaled).
When the partitioning is done, select the startup volume on your internal drive in the DU window. Select the Restore tab. Drag the icon of the startup volume to the "Source" field. Then drag the icon of the newly-created volume on the external drive to the "Destination" field. Make sure you have this right. Then click the Restore button, and the data on your startup volume will be copied to the external drive.

Looking for a disk management tools in JAVA

Hi everybody,
I am currently looking for tools or APIs designed for disk management. I explain : I would like to defrag or format a microSD card with Java code.
Is it possible since the way to get access to the memory card depends on the underlying OS. I know that the really defrag or format action is OS-independent, but filesystem type dependent.
Can you help me please ?
Thanks in advance.
Oliwood

These are system level, platform dependent actions and not the sort of thing Java is made for. If you search hard enough (read Google) you may find these types of tools using JNI for specific platforms, but I wouldn't count on it.

Is it possible to use SCOM 2012 R2 with the new Azure Managment Pack to monitor Aure Wadlog Events for azure sdk 2.5

My operations team has been using MOM 2007 and has recently migrated to SCOM 2012 R2.
Till now we are using Monitoring Pack management packs which were released way earlier (https://www.microsoft.com/en-us/download/details.aspx?id=11324),
and had a dependency on diagonstics connection string being present in the cscfg of Azure package.
This pack was allowing us to monitor the wad logs and events generated by applications.
However we plan to move to newer Azure managemen pack (http://www.microsoft.com/en-us/download/details.aspx?id=38414), which allows for discoverability.
I have 2 questions -
Is it possible to monitor Diagonstics Event Log with the new Monitoring Pack released on 10/2014 ? Or will the users still require the earlier pack for monitoring diagnostics installed in parallel ?
Azure SDK 2.5 got rid of diagonstics connection string. Is there any possible way to Monitor of Azure Diagonstics wadlogs using SCOM 2012 R2
Thanks,
Pratush

Hi Pratush,
I would like to suggest you go through the management pack guide to get details. And you should be able to create custom monitor to monitor event logs for Azure.
Hope the below links be helpful for you regarding to monitoring Azure:
