Review: VMware Virtual SAN turns storage inside-out

Review: VMware Virtual SAN turns storage inside-out
Convergence of compute and storage is all the rage in the virtualization market these days. You see it in Microsoft's Windows Server 2012 R2 with Hyper-V and Storage Spaces. You see it in third-party platforms such as Nutanix. And you see it in VMware's vSphere flagship with the addition of Virtual SAN, a new capability built into the ESXi hypervisor that turns the direct-attached storage in vSphere cluster nodes into highly available, high-performance shared storage. The goals behind Virtual SAN, or VSAN, are both to lower overall storage costs and to eliminate the I/O latencies associated with networked storage. VSAN achieves high availability by replicating storage objects (virtual machine disks, snapshot images, VM swap disks) across the cluster, allowing admins to specify the number of failures (nodes, drives, or network) to be tolerated on a per-VM basis.

Using VMware vSphere Storage Views Introduction When it comes to analyzing what storage (virtual or physical) is connected to what or how much storage is being used by what, the VMware vSphere Storage Views tab is where you need to go. The Storage Views tab is generated by a plug-in for the vSphere Client and you can view it on any object (VM, Host, Datacenter & cluster). In this article, I'll show you where to access the vSphere Storage Views tab, what plug-in makes it work, and how it can help you. What vSphere Plug-in makes Storage Views Work? While it should be enabled by default, the vCenter Storage Monitoring plug-in is what makes the Storage Views tab appear in the vSphere Client. VMware launches virtual SAN software VMware has introduced software designed to make it much easier for its customers to store large numbers of virtual machines (VMs) created with the company’s software. “It is about management simplification,” said Alberto Farronato, VMware director of product marketing for storage and availability. The software, VMware Virtual SAN (vSAN), is the company’s first foray into storage virtualization. The company made its name offering server virtualization and is also ramping up offerings for desktop and network virtualization as well.

VMware's Virtual SAN Threatens Traditional Data Storage Models VMware has launched the final part of its software defined data center puzzle: a virtual SAN product called Virtual SAN. The product has been in beta testing for the last six months, with around 12,000 customers, but there were still plenty of surprise announcements made at the launch event on March 6. The biggest of these was the maximum size of its Virtual SAN. Previously VMware had said that this would be 8 server nodes, and then 16.

VMware’s vSphere enables system administrators to create multiple virtual servers on a single physical server chassis. The underlying hypervisor, vSphere ESXi, can use both internal and external storage devices for guest virtual machines. In this article we will discuss the basics of using storage area network (SAN) storage on vSphere and the factors administrators should consider when planning a shared SAN storage deployment. VMware storage: SAN basics

Software-Defined Shared Storage Features: VMware Virtual SAN Contact Sales 1-877-486-9273 Virtual SAN VMware Virtual SAN is a radically simple, enterprise-class storage solution, enabling an ideal hyperconverged infrastructure for vSphere virtual machines. VMware launches efficient virtual storage solution VMware has launched Virtual SAN, an application-centric storage solution for virtualised networks. The new solution, built into VMware's vSphere kernel, provides hypervisor-converged storage, pooling internal magnetic disks and flash devices from x86 servers to produce a shared datastore for virtual machines. Virtual SAN can perform 2 million input/output operations per second (IOPS) on a read-only workload on a 32-node cluster, and 640,000 IOPS on a mixed workload on a 32-node cluster. The hypervisor-converged architecture lets Virtual SAN deliver the most efficient data path, which means its CPU resource consumption is less than 10 per cent. Scalability and integration

VMware virtual servers offer advanced shared storage options Citrix Systems Inc., Microsoft Corp. and VMware Inc. all present IT shops with a variety of options to provision and manage the shared storage systems that are linked to their virtual server technology. Not surprisingly, VMware, the vendor with the most mature product in the market, offers the most advanced support for block- and file-based networked storage alternatives and makes available application programming interfaces (APIs) data storage vendors can use to ensure their systems will work smoothly with its virtual server software, noted Marc Staimer, president at Dragon Slayer Consulting in Beaverton, Ore. In this podcast interview, Staimer outlines VMware virtual servers, what VMware has done to improve the way its products work with storage, contrasts where Microsoft Hyper-V and Citrix XenServer stand in comparison, and offers up advice on choosing the right data storage option for your virtual server environment.

Virtual Networking 101: Understanding VMware Networking May 30, 2012By Petra Jorgenson On a basic, structural level, virtual networks in VMware aren’t that different from physical networks; vSphere is designed to mimic the functions of a physical network, so a lot of the network hardware you’ll find in the real world, you’ll find virtualized in VMware. If you understand how physical networks operate, then understanding virtual networking shouldn’t be too difficult. Before jumping into an explanation of how VMware handles virtual networking, I’ll first provide a quick refresher of the basic equipment that makes up a physical network. If you already have a firm understanding of how networking works, then you can skip the following paragraph.

VMware To Complete Storage Virtualization With VVols VMware launched its Virtual SAN (VSAN) hyperconverged storage for its vSphere virtualized servers last fall and started shipping it this spring and has seen very good uptake of the technology, with 12,000 beta tests through the spring and more than 300 customers in production in the first three months of commercial availability. But that is not the end of the virtual storage story at VMware. The next release of the hypervisor will include a feature called Virtual Volumes, or VVols for short, and this type of storage virtualization will be employed across all kinds of devices to virtualize the data plane between virtual machines and physical storage devices. In a way, VSAN offers a kind of preview of the VVols technology. In a software-defined everything world, every element of compute, storage, and networking should be individually and programmatically managed with the option of then grouping elements together to be managed as a whole when it is appropriate.
