VMware Studio 2 Beta&vApps - Community Roundtable podcast #54

The beta release ofVMware Studio 2.0and using it to create vApps was the topic of this week's podcast. Studio 1.0 came out last year; this beta moves the bar significantly. We also got into why you as a VMware admin should care about vApps - without being too hyperbolic I think it's going to be the organizing paradigm that will change how we think of applications -- from a VM level to something much higher-level and more manageable. Going back to Studio, here's the high-level description:

VMware Studio 2.0 helps configure, build, deploy, customize and maintain vApps and virtual appliances. These solution stacks can be deployed on VMware vSphere 4.0 or in the cloud and can be managed from the VMware Studio web console or from VMware vCenter Server. In this webinar, software vendors, application developers and IT administrators will get an overview of vApps and virtual appliances followed by what's new in Studio 2.0. We will walk you through the entire build process by starting with an application created in Eclipse (via the Eclipse plug-in in Studio) and demonstrating how it can be packaged as either a vApp or virtual appliance in OVF format. The process will also reveal various automated tools available, for creating a clean out-of-box experience, such as specifying exact OS requirements, building an update repository, adding custom management services and adding existing VM builds as input.

As always, listen in via the widget to the right, themp3, or viaiTunes.

Non-Studio topics we discussed:

A few of the podcast attendees have already weighed in with their reactions - mostly about the significance of using vApps in the enterprise. I wasn't kidding when I used the word'paradigm'above.

Stu from vinternals.com, who is known totell it like it is,liked it, he reallyliked it.

Rich Brambley: VMware Studio 2.0 and OVF Exports: Blurred Products or Outside The Box Thinking? | VM /ETC.

I’ll outline potential Studio / OVF usage that may be“outside of the box”from the VMware software’s intended purpose. Or is it? You tell me.

vCenter / Deploy from template

The ability to export any VM as an OVF from the VI Client by itself, let alone VMware Studio, opens the door for template deployment in environments without vCenter. Build a VM to desired corporate standards and then export a copy of it to a shared network drive where it can be used as a master image for future deployments on any virtual platform that supports OVF.

With VMware Studio build a multiple VM apllication as a vApp. Configure the web server and the database for example, and before adding any data export the combination as an OVF. Deploy the vApp OVF as a master template as needed.

Sure, vCenter offers so much more automation for this process, but what about for deployment between ESX hosts that are not managed by the same vCenter or don’t share the same storage? ...

Daniel Eason:Virtually Insane?: The Virtual Glue.

By deploying turnkey Virtual Appliances with for example a new SAP ERP Landscape on 10-20 Machines in a period of say 2-3 days rather than 2-3 Machines in 10-20 days clearly shows that current long deployment processes are redced and less people need to be involved on a deployment when using Virtual Appliances alongside side orchestration and groupings such as vApp. The problem however with this is you get people protective on roles and the oldage turf war developing so it is not something that can be just implemented straight away. ...

vApps functionality in vSphere enables organisations to reduce even more manual and people process. It enables you to compile the complete application stack and configure all associated components by one single master definition. Tie this in with some VMware orchestration capability where you could say deploy via API the Database components as part of the VM build and provision the relevant Networking components and it is clear the potential is going to be huge.


For the Canadians hiding among us, happy belated Canada Day. For the USians, happy Fourth. For the rest of the world, keep on working and we'll see you next week.

Top 5 Planet V12n blog posts week 26

It was a good week again. Some awesome blog posts of which the following five were my favorites. It seems like it is getting harder to create a top 5 every week. I picked technical and non-technical articles this week. Enjoy,

  • Maish Saidel-Keesing - ESX 4.0 running a vSphere Lab -part 1&2
    I have a dedicated Blade server for this purpose, and IBM HS21 E542 CPU (Quad) with 2GB of RAM and 150GB HD. Now you might say - and rightfully so - what can you do with only 2gb of RAM?? Well nothing really - that is why I have upped the RAM on the server to 8GB so I can get some testing done. So since this is going to be a test bed for my full migration for the production system, I wanted to get it as close as possible to what my production system will be like.
  • Steve Chambers -Stabilizing vSphere
    Gene Kim said once that“virtualization amplifies bad practice”, and this has been seen commonly out there (just today I saw, on Twitter, that a customer changed their SRM password–no change process–and killed their DR environment). Virtual server sprawl, eggs in one basket: there are many examples why if you are bad at IT, you’re going to be really bad at virtualization.
  • Rodney Haywood -Attend VMworld 2009
    This morning on the VMTN podcast John Troyer stated it was time for some blogs post in the community on why go to VMworld. Hey, count me in.I do feel that I am qualified to comment here. I am a VMworld Alumni, having attended the last 3 years. For two years it was funded by my employer (thanks guys). One year, because I was in the period of transition between two employers, my wife paid, serious. Don’t forget, I live in Australia so it’not an inexpensive exercise. I have lived through and succeeded in the task of negotiating with my wife as to why I should invest in taking an overseas trip just to attend VMworld.
  • Duncan Epping -VMFS/LUN size?
    A question that pops up on the VMTN Community once every day is what size VMFS datastore should I create? The answer always varies, one says“500Gb”the other says“1TB”. Now the real answer should be, it depends.
  • Scott Lowe -New User’s Guide to Configuring VMware ESX Networking via CLI
    A lot of the content on this site is oriented toward VMware ESX/ESXi users who have a pretty fair amount of experience. As I was working with some customers today, though, I realized that there really isn’t much content on this site for new users. That’s about to change. As the first in a series of posts, here’s some new user information on creating vSwitches and port groups in VMware ESX using the command-line interface (CLI).

SQL Sever performance on VMware vSphere 4.0

    VMware recently published a whitepaper titled“Performance and Scalability of Microsoft SQL Server on VMware vSphere 4“that demonstrates VMware vSphere 4.0 can virtualize large SQL Server deployments with excellent performance and scalability. The paper documentsresults for a resource intensive OLTP workload running against a SQL Server 2008 database on the Windows Server 2008 operating platform and highlights single-VM as well as multi-VM performance.

  • In an 8vCPU virtual machine, we achieve OLTP throughput that is 86% of physical machine performance 
  • In consolidation experiments with multiple 2-vCPU virtual machines, aggregate throughput scales linearly until physical CPUs are saturated 

Single-VM Performance Relative to Native 

    The table below summarizes the performance relative to the physical machine as we scale-up the vCPUs in a VM running our workload.


Number of Virtual CPUs

Ratio to Native

1

92%

2

92%

4

88%

8

86%

 
    At 1,2 and 4vCPUs on the 8pCPU server, ESX is able to effectively offload certain tasks such as I/O processing to idle cores.
Even at 8vCPUS on a fully committed system, vSphere 4.0 still delivers excellent performance .

    The following table summarizes the resource intensive nature of the workload used for the tests.

Metric

Physical Machine

Virtual Machine

Throughput in transactions per second

3557

3060

Disk I/O throughput (IOPS)

29 K

25.5 K

Disk I/O latencies

9 milliseconds

8 milliseconds

Network bandwidth receive

Network bandwidth send

11.8 Mb/s

123 Mb/s

10 Mb/s

105 Mb/s send


Multi-VM Performance and Scalability

    Multiple SQL server VMs running a resource intensive OLTP workload can be consolidated to achieve excellent aggregate throughput with minimalperformance impact to individual VMs. In the figure below, we plot the total throughput as we add eight 2-vCPU SQL Server VMs onto an 8-way host.

Scaleout_graph4

    The cumulative throughput increases linearly as we add up to four virtual machines (eight vCPUs).As we over-commit the physical CPUs by increasing the number of VMs from four to six (factor of 1.5), the aggregate throughput increases by a factor of 1.4 Adding eight VMs to this saturates the physical CPUs on this host, yet ESX is able to utilize the few idle cycles to deliver 5% more throughput.

    The data clearly shows that performance is not a barrier for configuring large multi-CPU SQL Server instances in virtual machines or consolidating multiple virtual machines on a single host to achieve impressive aggregate throughput on vSphere 4. 

For more details regarding these tests, we refer you to the paper at Performance and Scalability of Microsoft SQL Server on VMware vSphere 4

Why You Shouldn't Miss VMworld 2009

Category: Nontechnical information, VMworld

If you are still wondering whether or not you should attend VMworld 2009, then hopefully this post will change your mind.

Besides having numerous sessions, speakers, and vendors present, you will have the chance to network and learn from the best in the industry.

But hey, if that's not enough to convince you to register, hear it from VMworld alumni Rodney Haywood. Haywood hasn't missed a VMworld in the last three years, even paying his own way one year...and he lives in Australia.

One of the reasons from Haywood's post is that"with so many sessions and such a large section of vendors there WILL be relevant content to your needs and area of interest. You will come away with concrete things that will make a difference. Every year VMworld has set my agenda for the next 12 months, none more than last year!"

To read more about why you shouldn't miss VMworld 2009,visit Rodney Haywood's blog:http://rodos.haywood.org/2009/06/attend-vmworld-2009.html.

Measuring the Cost of SMP with Mixed Workloads

It is no secret that vSphere 4.0 delivers excellent performance and provides the capability to virtualize the beefiest of workloads. Several impressive performance studies using ESX 4.0 have been already been presented. (My favorite is this database performance whitepaper.) However, I continue to hear questions about the scheduling overhead of larger VMs within a heavily-utilized, mixed-workload environment. We put together a study using simple variations of VMware’s mixed-workload consolidation benchmark VMmarkto help answer this question.

For this study we chose two of the VMmark workloads, database and web server, as the vCPU-scalability targets. These VMs represent workloads that typically show the greatest range of load in production environments so they are natural choices for a scalability assessment. We varied the number of vCPUs in these two VMs between one and four and measured throughput scaling and CPU utilization of each configuration by increasing the number of benchmark tiles up to and beyond system saturation.

The standard VMmark workload levels were used and were held constant for all tests. Given that the workload is constant, we are measuring the cost of SMP VMs and their impact on the scheduler. This approach places increasing stress the hypervisor as the vCPU allocations increase and creates a worst-case scenario for the scheduler. The vCPU allocations for the three configurations are shown in the table below:

 

Webserver vCPUs

Database vCPUs

Fileserver vCPUs

Config2 uses the standard VMmark vCPU allocation of 10 vCPUs per tile. Config1 contains 20% fewer vCPUs than the standard while Config3 contains 40% more than the standard.

We also used Windows Server 2008 instead of Windows Server 2003 where possible to characterize its behavior in anticipation of using Server 2008 in a next-generation benchmark. As a result, we increased the memory in the Javaserver VMs from 1GB to 1.4 GB to insure sufficient memory space for the JVM. The table below provides a summary of each VM’s configuration:

Below is a basic summary of the hardware used:

  • Dell PowerEdge R905 with 4 x 2.6GHz Quad Core AMD Opteron 8382
  • Firmware version 3.0.2 (latest available).
  • 128GB DDR2 Memory.
  • 2 x Intel E1000 dual-port NIC
  • 2 x Qlogic 2462 dual-port 4Gb
  • 2 x EMC CX3-80 Storage Arrays.
  • 15 x HP DL360 client systems.

Experimental Results

Figure 1 below shows both the CPU utilization and the throughput scaling normalized to the single-tile throughput of Config1. Both throughput and CPU utilization remain roughly equal for all three configurations at load levels of 1, 3, and 6 tiles (6, 18, and 36 VMs, respectively). The cost of using SMP VMs is negligible here. The throughputs remain roughly equal while the CPU utilization curves begin to diverge as the load increases to 9, 10, and 11 tiles (54, 60, and 66 VMs, respectively). Furthermore, all three configurations achieve roughly linear scaling up to 11 tiles (66 VMs). CPU utilization when running 11 tiles was 85%, 90%, and 93% for Config1, Config2, and Config3, respectively. Considering that few customers are comfortable running at overall system utilizations above 85%, this result shows remarkable scheduler performance and limited SMP co-scheduling overhead within a typical operating regime.

FIG1_Alternatev-CPUscaling-4b 

Figure 2 below shows the same normalized throughput of Figure 1 as well as the total number of running vCPUs to illustrate the additional stresses put on the hypervisor by the progressively larger SMP configurations. For instance, the throughput scaling at nine tiles is equivalent despite the fact that Config1 requires only 72 vCPUs while Config3 uses 126 vCPUs. As expected, Config3, with its heavier resource demands, is the first to transition into system saturation. This occurs at a load of 12 tiles (72 VMs). At 12 tiles, there are 168 vCPUs active–48 more vCPUs than used by Config2 at 12 tiles. Nevertheless, Config3 scaling only lags Config2 by 9% and Config1 by 8%. Config2 reaches system saturation at 14 tiles (84 VMs), where it lags Config1 by 5%. Finally Config1 hits the saturation point at 15 tiles (90 VMs).

FIG2_Alternatev-CPUscaling-5b 

Overall, these results show that ESX 4.0 effectively and fairly manages VMs of all shapes and sizes in a mixed-workload environment. ESX 4.0 also exhibits excellent throughput parity and minimal CPU differences between the three configurations throughout the typical operating envelope. ESX continues to demonstrate first-class enterprise stability, robustness, and predictability in all cases. Considering how well ESX 4.0 handles a tough situation like this, users can have confidence when virtualizing their larger workloads within larger VMs.

(*) The spartan memory and disk allocations for the Windows Server 2008 VMs might cause readers to question if the virtual machines were adequately provisioned. Since our internal testing covers a wide array of virtualization platforms, reducing the memory of the Standby Server enables us to measure the peak performance of the server before encountering memory bottlenecks on virtualization platforms where physical memory is limited and sophisticated memory overcommit techniques are unavailable. Likewise, we want to configure our tests so that the storage capacity doesn’t induce an artificial bottleneck. Neither the Standby Server nor the Javaserver place significant demands on their virtual disks, allowing us to optimize storage usage. We carefully compared this spartan Windows Server 2008 configuration against a richly configured Windows Server 2008 tile and found no measurable difference in stability or performance. Of course, I would not encourage this type of configuration in a live production setting. On the other hand, if a VM gets configured in this way, vSphere users can sleep well knowing that ESX won’t let them down.

Top 5 Planet V12n blog posts week 25

It was one of those weeks again. I had a lot to do, and there is still a lot left to do. I just finished this top 5 and the quality of the articles is again very high. Especially Chad's article, wow... Anyway, start reading and enjoy. This is my gift to all fathers out there.

  • Mike Laspina -Automating vSphere ESX4 Host Installations
    The custom VMware kernel incorporates Linux kickstart scripting functionality to invoke automated installations. The script location is defined as part of the Syslinux functionality and is available as a menu at boot time. A control file located on the boot media provides these variable control elements. Depending on the media type Syslinux uses a respective cfg file to implement this function. The various available Syslinux boot methods that I am aware of are USB, CD, DVD, PXE and gPXE. In this blog I will demonstrate an ISO CDROM method to perform the automated boot cycle. Any of the boot methods mentioned will all work and have varying levels of complexity to achieve.
  • Chad Sakac -VMware I/O queues,“micro-bursting”, and multipathing
    A shallow queue somewhere in the IO path (or an overflowing port buffer) will cause the I/O to back off.   You need the queues to be deep enough to withstand the bursts–sometimes increasing the queue depth is important.  Now, if the problem isn’t actually the bursts, but the I/O service time not being sufficient for the sustained workload (aka you have a slow, or underconfigured array), increasing the queue depth will help for only a fraction of a second, after which the deeper queue willstillfill up, and now you just have increased the latency even more.
  • Bouke Groenescheij -Queue Depth and more
    Last few weeks we have had some issues regarding our HDS USP-V. For some reason a SCSI lock locked the whole VMFS and all ESX servers in that cluster were not able to read/write to the VMFS anymore. The LUN was still available, however the VMFS not. So this crashed all the VMs in the cluster. The incident repeated itself after 6 weeks, on another server, other chassis, other switches and so we contacted VMware and HDS to help us in this situation.
  • Duncan Epping -VCDX Defense, the blog article
    The last part of the VCDX certification is the defense. In short: you will need to write a design, fill out the application and defend your design during a two to three hour session. Although I can describe it in 30 words it is not as simple as it may sound. First of all your design needs to meet specific requirements. I can’t go in to the details unfortunately but when you receive an invitation you will receive all the prerequisites. Like me, most of you done numerous designs, but keep in mind it needs to be in English and so will your defense need to be. This is an extra barrier for many of the non- native speakers; I know it was for me.
  • Rodney Haywood -VMware vShield
    You can think of vShield as providing firewalls inside your ESX hosts. Each host runs one or more vShields which is a VM (provided as an OVF) which acts as a bridge between the real network and your Virtual Machines. These numerous vShield machines are all managed by a central vShield Manager (also provided as an OVF, one per vCenter Server). The vShield creates two zones, one protected and the other unprotected. The traffic enters the protected zone from the unprotected zone. As it crosses the zones the vShield performs traffic analysis, discovery and stateful firewall protection.
