  • Source: Intel preso at Vmworld.Workingclosely with Vmware and our OEMs, VMmark performs very efficiently on Xeon 5500 series.As you can see all the major OEMs has published Vmmark scores on Nehalem based servers – super efficient virtualization is one of the requirements for cloud computing; Xeon 5500 series is the platform of choice
  • This is another example of how VMware enables higher performance from physical hosts.
  • The good news with SQL server consolidation – and Oracle consolidaiton – is that you can realize very significant cost savings not just on the infrastructure side, but also on the licensing side. Today, most SQL / ORCL database licenses are used at just 5% - 10% on average. By consolidating, you not only increase infrastructure utilization, but also license utilization. In this example, we are going from 8 individual DB each on a dedicated host, to a couple of shared host running 8 DB instances. With Enterprise edition, just need to license physical processors, so you effectively consolidate your licenses in addition to servers.This leads to a very significant reduciton in licensing costs, especially since software licenses tend to dominate the cost structure for SQL deployments.
  • Failback requires some setup _after_ fail-over is performed.Unique featuresSite Recovery Manager2 main featuresAutomated DRProof to Audit or Business that IT has done the DR properly with minimal hit on IT resources.It is possible because we have a standard API that many storage vendors have written to. They allow us to control their array (e.g. discover LUN, stop replication)Global ViewBrowse and Search across multiple data center. Scale up to 10 data centers worldwide.
  • Technically, you maybe able to hit 120 VM or more per cluster. But from best practice point of view, we don’t recommend such high ratio. 120 VM in 7 hosts (1 is assumed to be unavailable) is > 17:1 ratio
  • Infra VMs (vCenter, Update Manager, etc) connect to Management LAN. Since they are on the same physical NIC, we need to create VLAN.
  • In most customer environments, early virtualization deployments often focus on virtuliazation “candidates” that are considered lower risk – perhaps file and print servers or applications that are not considered mission critical. As customers seek to expand the virtualization footprint, by definition they want to virtualize business-critical apps – and vCenter AppSpeedis an excellent tool to help them achieve that with confidence. There are two main use cases for AppSpeed: 1. Guarantee application SLA for virtualized multi-tier apps 2. Perform an “Assured Migration”Guarantee application SLAAppSpeed allows you to continually monitor the performance of an application ensuring SLAs are met. The product automatically discovers and maps applications and components all the way down to specific database tables…even if the database or any app tier is still on a physical system. The product will then monitor real-time user end user experience for all transactions – breaking down performance into its component parts (e.g. network, application and database latency). Any time an application does not meet its assigned threshold, the user is alerted, and can quickly analyze the root cause of the problem. Users can quickly identify and dive into the application’s dependencies to pin-point the source of the problem. Perform “Assured Migration”One of the top inhibitors to Virtualizing applications is the concern expressed by app owners that applications may not perform as well in virtualized environments. The answer is to measure performance on the physical app pre virtualization, and again after it has been virtualized. In both use cases, AppSpeed, provides a shared view of the application that be understood by both IT and application owners, engendering better communication about application performance overall, and reducing fingerpointing and enable faster troubleshooting and resolution if and when trouble arises. In short, With vCenter AppSpeed, customers can be sure that their business critical applications will run as well or better in virtual mode.

    6. 6. VMware VMmark<br />Use VMmark as the basis for CPU selection<br />It is the official benchmark for VMware, and it uses multiple workload<br />Other benchmark are not run on vSphere, and typically test 1 workload<br />Use it as a guide only<br />You need head room and HA.<br />How it’s done<br />1 Tile = 6 VM. Each is 1 vCPU.<br />MS Exchange, MySQL, Apache, J2EE, File Server, Idle VM<br />Result page: <br />www.vmware.com/products/vmmark/results.html<br />VMmark 1.1 results is directly comparable to VMmark 1.0 results. The underlying virtual hardware definitions and load levels for each workload have not changed.<br />1 Tile = 6 VM<br />Each 2 CPUs<br /> 2GB RAM<br />
    7. 7. Sample Results (as at Feb 2010. Major update in May)<br />VMware does not recommend 1 OEM over the other. <br />I use 1 OEM here so we don’t compare between OEM<br />Look at this number<br />This number is when comparing with same #Tiles<br />Opteron 8439, 24 cores<br />Xeon 5570, 8 cores<br />Opteron 2435, 12 cores<br />Xeon 5470, 8 cores<br />This tells us that DL380 G6can run 17 Tiles, at 100% utilisation.<br />Each Tile has 6 VM, but 1 is idle.<br />17 x 5 VM = 85 active VM in 1 box!<br />At 70% ESX host utilisation, that’s around 59 VM.<br />DL 385 G6 runs 11 tiles.<br />The 2 boxes have similar date submission, around mid 2009.<br />
