VMware releases public beta of Virtual Volumes

Besides releasing the public beta 2 for vSphere 6.0 today, VMware also released a beta for Virtual Volumes (VVOLs). Virtual Volumes allows a Virtual Machine and its disk to become a unit of storage management for a storage system by encapsulating virtual disks and virtual machine files. These files are stored natively on the storage system. VVOLs uses the vSphere APIs for Storage Awareness (VASA) which makes the storage system aware of the virtual volumes and how they relate to the virtual machines. Read more [...]

VMware Virtual SAN Public Beta

Among all the announcements made in the first day of VMworld 2013, the public beta of VMware Virtual SAN technology is one of the most interesting. Virtual SAN is a software-defined storage tier embedded directly within vSphere 5.5 hypervisor (but licensed separately) and constitutes (with NSX) one of the key components of VMware’s vision of software-defined datacenter. vSAN leverages the local storage (each host will require at least one SSD and one magnetic disk) from a number of ESXi hosts Read more [...]

Survey: VMware vSphere storage reservation

Frank Denneman senior technical marketing architect within the Cloud Infrastructure Product Marketing group at VMware is conducting a survey about storage reservation, a feature coming to vSphere which is currently in development. The current version of Storage I/O Control provides tools to prioritize and provide fairness to I/O streams of virtual machines. However the current version does not provide a function to specify number of IOPS to guarantee a minimum level. Because the storage subsystem Read more [...]

Paper: VMware vSphere VMFS Technical Overview and Best Practices

VMware has updated its VMFS Technical Overview paper for vSphere 5.1. The Paper titled VMware vSphere VMFS Technical Overview and Best Practices contains 17 pages and details how the VMware File System (VMFS) works. VMFS increases resource utilization by providing multiple virtual machines with shared access to a consolidated pool of clustered storage. VMFS provides the basis for other VMware services like virtual machine snapshots, VMware vSphere Thin Provisioning, VMware vSphere vMotion, VMware Read more [...]

Paper: VMware vSphere Storage APIs – Array Integration (VAAI)

VMware has released a paper titled: VMware vSphere Storage APIs – Array Integration (VAAI), the paper which contains 19 pages details the current vSphere Storage APIs – Array Integration (VAAI) available today. When VAAI was introduced in the vSphere 4.1 timeframe there were three block based storage (Fibre Channel, iSCSI and FCoE) and with the introduction of vSpere 2 VAAI primitives for NAS storage and vSphere Thin Provisioning were introduced. VMware vSphere Storage APIs – Array Integration Read more [...]

Paper: VMFS File Locking and Its Impact in VMware View 5.1

VMware has released a paper titled:"VMFS File Locking and Its Impact in VMware View 5.1". The paper which contains 16 pages describes what VMware has done in order to extend the support to a maximum of 32 hosts in a ESX cluster when VMware vStorage Virtual Machine File System (VMFS) is used. Versions prior to View 5.1 only supported 8 hosts in an ESX Cluster when (VMFS) was used, when NFS storage is used for linked clone replica creation.   The paper answers the following questions, among Read more [...]

Paper: VMware vSphere Storage DRS Interoperability

On Friday VMware published a paper intended for costumers that are evaluating an implementation of VMware vSphere Storage DRS in combination with advanced storage device features or other VMware Products. Virtual machine storage provisioning historically has imposed operational challenges. Monitoring datastore capacity and I/O load has proven to be very difficult and as a result is often neglected. During the provisioning process for virtual machines, virtual disk datastores are often randomly Read more [...]

Brian Madden: “I was wrong about how VMware View 5.1’s new Storage Accelerator works. It’s way cooler than I thought!”

A very interesting post of Brian Madden about "VMware View Storage Accelerator": Last week VMware announced View 5.1. One of the major new features is this thing called "View Storage Accelerator," or "VSA." In my article about View 5.1, I wrote that I wasn't particularly excited about VSA. It turns out I didn't fully understand how it worked. If you're not familiar with VSA, it's the productized implementation of a feature of vSphere 5 called "Content-Based Read Cache." When enabled, the vSphere Read more [...]
