  • In terms of absolute numbers, with ESX 3.5, we address the performance requirements of a large section of workloads today. In 2009, we will now have the ability to accommodate some of the largest workloads out there. We’ll support VMs with up to 8 Virtual CPUs (8-way SMP) These VMs can be assigned up to 255GB of RAM We can sustain 40Gb/s of network I/O, and We can push up to 200,000 I/O operations per second! There aren’t a lot of workloads out there today that come close to limits we will handle. Our goal? There should not be a single workload out there which isn’t a great candidate for virtualization. We think we’re pretty close today. In 2009 we hope we’ll have achieved this goal. Peak means peak hours: 7 am – 7 PM
  • VMware Fault Tolerance is a component of VMware vSphere™ that ensures continuous availability for virtual machines against hardware failures. VMware FT creates virtual machine “pairs” that run in lock step - essentially mirroring the execution state of a VM. To the external world they appear as one instance (one IP address, one application) – but they are fully redundant instances. In the event of an unexpected hardware failure that causes the active, primary VM to fail – a secondary, formerly passive VM immediately picks up where the primary left off, and continues to run, uninterrupted, and without any loss of network connections or transactions. This technology will also work across any application & any OS without modifications, without scripting, and provides a much more cost-effective way of running mission critical workloads than fault-tolerant hardware dedicated entirely to individual applications. At VMware, we say that “virtual is better than physical” very frequently, and our advanced development work on providing continuous availability for VMs – to enable VMs to keep executing, completely uninterrupted by unexpected hardware failures - is one of the great examples of why this is true. We have taken technology implemented with very complex custom hardware and delivered it for commodity x86 hardware. We believe this technology, and all of the other business continuity benefits of virtualization will drive more and more mission critical workloads into virtual machines because they can enable HIGHER levels of availability, at a fraction of the cost & complexity of physical solutions. DETAILS ( use only as needed) Limitations of FT initially: dependent on shared storage, Uniprocessor VMs only. Additional overhead also associated with this type of solution. Overall performance impact still TBD, but you can expect more CPU & memory resources will be required to run the 2 nd VM, and applications may experience small amounts of added latency. In spite of initial limitations, longer term trends are in our favor: FT will take advantage of hardware assisted virtualization in CPUs, more and more CPU cores becoming available to offload overhead, and high-speed network improvements like 10gigE to reduce latencies…
  • vCenter Data Recovery is a new tool in for VMware vSphere™ users that provides complete data protection for your virtual machines. Note that it is appropriate for smaller environments (100 VMs or less). - It’s a disk-based solution that’s easy to use and fast to backup and restore. - It’s built on the VCB API and is fully integrated with vCenter management to enable centralized and efficient scheduling of backup jobs using an intuitive workflow. Step 1: Backing up your virtual machines is a snap – - First you schedule your backups directly through the vCenter interface. <FIRST BUILD CLICK> - Snapshots are taken at your scheduled intervals and written to near-line storage (local or shared). - After the first full VM backup, subsequent backups are incremental to save time and disk space. - vCenter Data Recovery also uses disk de-duplication to further reduce the disk space required for backup storage. <SECOND BUILD CLICK> Step 2: The toughest part of the backup process is recovering your apps and data. vCenter Data Recovery makes this process quick and easy – - When a VM goes down, you go to vCenter and quickly access the directory of backup VMs and files. <THIRD BUILD CLICK> - Select which ones you want to recover (individual files or complete VM) and restore in seconds/minutes - Your applications and data are back up and running!
  • VMware vShield Zones, a new security service for VMware’s Cloud OS, vSphere, ensures strict compliance with security policies and industry regulations for user data as customers adopt cloud computing with virtual environments for increased efficiency and flexibility. Previously, compliance required diverting network traffic to external physical appliances resulting in disconnected ‘islands’ of infrastructure. With VMware vShield Zones, customers can now create logical zones in the virtual datacenter that span all of the shared physical resources, and each zone represents a distinct level of trust and confidentiality. This allows businesses to comply with corporate security policies and regulations on data privacy while still running applications efficiently on shared computing resource pools.   Traditional security products, such as firewall appliances, require that all network activity pass through a handful of fixed physical locations in order to be monitored.   Virtualized applications, in contrast can be migrated between physical hosts for higher resource efficiency and improved uptime. Therefore, companies virtualizing security sensitive applications faced the choice of either leveraging virtualization capabilities such as live migration for optimal load balancing and availability, or enforcing strict security compliance. To solve that dilemma, most customers ended up dividing their virtual environments into smaller, less efficient clusters for areas such as their Internet-facing demilitarized zones (DMZ’s) or consumer credit data processing systems subject to Payment Card Industry regulations. VMware vShield Zones enables customers to create security zones within enterprises or in multi-tenant cloud infrastructures, where security policies are enforced even as virtual machines dynamically migrate between hardware devices. Deployed as a virtual appliance and integrated into vCenter Server, vShield Zones makes it easy to centrally manage and enforce compliance with security policies across large pools of servers and virtual machines. Built-in auditing capabilities make compliance straightforward and verifiable.  
  • vCenter host profiles simplify and standardize ESX host configuration. This feature in vCenter Server 4.0 allows the creation of a “golden profile” from an existing host and using this as a template to configure other hosts Host profiles can be associated with other hosts/clusters and compliance to these profiles can be monitored and enforced automatically This is a powerful capability – especially when used in conjunction with the vNetwork Distributed Switch, reducing considerably the time spent in making sure of ESX host configurations In large scale environments, when ESX hosts are being added every day or every hour, standardizing the storage, network and security configurations of these hosts becomes really important. Managing change can also be complex especially when the same change needs to be applied to many hosts (example – array goes through firmware upgrade, and multipathing settings need to be changed across all hosts in a cluster) The Host Profiles feature allows you to export configuration settings from a gold reference host and save them as a portable set of policies, called a host profile. You can then use this profile to quickly configure other hosts in the datacenter. Configuring hosts using this method drastically reduces the setup time of new hosts: 10’s of steps reduced to a single click. Host profiles also eliminate the need for specialized scripts to configure hosts. Additionally, vCenter uses the profile as a configuration baseline, so you can monitor for changes to the configuration, detect discrepancies and fix them. Host profiles eliminate per-host, manual, or UI-based host configuration and efficiently maintain configuration consistency and correctness across the entire datacenter.
  • New licensing consists of two new customer-facing interfaces: vCenter license reports and administration License portal Key theme: simplification! Better match between how we sell and how we license Compliance: easy to overdeploy, but also easier to detect overdeployment Flex licensing is replaced by simple license keys Each vSphere host is assigned only 1 single license key for the entire “bundle” (e.g., Enterprise) rather than a separate license for each feature Same license key can be shared by many vSphere hosts, subject to the key’s maximum CPU count New centralized license key administration in vCenter No separate license server to manage or monitor – license administration is a native vCenter feature vCenter can be used to assign license keys to vSphere hosts via a simple UI Centralized vCenter report on all hosts and license keys in inventory enables easy monitoring of license state and compliance New license portal provides more accurate view of entitlement License keys linked to purchase history, including upgrades and license recombinations (i.e., division/combination of license quantities into more/fewer keys) Contract administration self-service allows addition and removal of license admins and support admins with access to specific licenses
