VMware storage: SAN configuration basics

VMware storage: SAN configuration basics
VMware storage entails more than simply mapping a logical unit number (LUN) to a physical server. 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 vSphere supports internally-connected disks that include JBODs, hardware RAID arrays, solid-state disks and PCIe SSD cards. SAN storage, however, provides a shared, highly available and resilient storage platform that can scale to a multi-server deployment. It is possible to use NAS and SAN-based storage products with vSphere, but in this article we will consider only SAN, or block-based devices. VMware file system and datastores

Storage Meat: VMware Storage – NFS, Fibre Channel or ISCSI This is the first in what will be a series of posts on storage considerations for VMware. This first post discusses the practicality of using NFS storage as an alternative to block based storage in virtualized environments. I have no axe to grind or specific product to push, my company represents leading storage solutions for both NAS and SAN. In the past if someone had said to me that they wanted to use something other than Fibre Channel for their VMware environment I had one of two thoughts. “I guess you can’t afford Fibre Channel or this must be a small environment”.

Storage virtualisation vs software-defined storage - StorageBuzz The aim of this blog post is to try to iron out some misunderstandings in two common terms in storage. Two terms that are actually really rather connected; storage virtualisation and software-defined storage. First let's deal with storage virtualisation. VMware vSphere Storage Appliance (VSA) for Shared Storage End of Availability VMware is announcing the End of Availability of all vSphere Storage Appliance versions, effective April 1, 2014. After this date you will no longer be able to purchase this product. All support and maintenance for vSphere Storage Appliance 5.5 will be unaffected and will continue to follow the Enterprise Infrastructure Support Policy. The End of General Support life date for customers with vSphere Storage Appliance 5.5 remains September 19, 2018. Support contracts can be renewed beyond End of Availbaility until End of General Support.

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.

ISCSI Basics - Thomas-Krenn-Wiki This article will explain the principle function manner of iSCSI (Internet Small Computer Systems Interface). Like Fibre Channel, iSCSI provides all of the necessary components for the construction of a Storage Area Network. iSCSI is defined in RFC 3720. iSCSI Components For iSCSI communication, the following components talk with each other: iSCSI Initiator iSCSI Target iSCSI Initiator

VMworld 2014 VMware vCloud Air and ViPR Object Storage This one is short and sweet! The vCloud Hybrid Service is no more, and is now VMware vCloud Air! Furthermore – it keeps getting bigger (more locations), and better (more capabilities – DR as a Service, Backup as a Service, and Platform as a Service) – with one of the new additions being one of the industries’ richest web-scale, geo-dispersed and efficient - which can translate into the lowest cost model – object (and HDFS!) store! 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).

Virtualized Network Isolation for a Malware Analysis Lab When analyzing malware, it helps to have an isolated laboratory environment that you can infect with the malware sample to interact with it while learning about its capabilities. The lab typically involves several computer systems networked together. The computers can be physical boxes, but are often virtualized using tools such as VMware and VirtualBox for convenience and control purposes. The Need for Isolating the Malware Analysis Laboratory How To Create VMware Virtual Volumes How To Create VMware Virtual Volumes VVOLs, as they're known, could revolutionize your datacenter. Learn how they work and how to set them up. By Tom Fenton02/26/2015

Converged Storage for VMware Imagine what you can achieve by combining the power of VMware vSphere with storage platforms designed to eliminate the challenges of server and client virtualization. HP’s next generation of Converged Storage solutions are designed to enhance the benefits of VMware vSphere, VMware View, and VMware vCloud Solutions. With HP storage supporting your VMware deployments, you are able to: 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. To connect to a network, a computer must be network-capable, meaning that it must have a working network interface controller (NIC), also known as a network card or network adapter, installed.
