Stephen Foskett spoke with Cody Hosterman and Anthony Ferrario from Pure Storage to find out how the company is meaningfully integrating VVols support into FlashArray, and why it’s taken some time for the industry to adopt the technology.
With VMworld US 2018 just around the corner, Matt Leib looks back at how VMware as a company has changed. For him, the biggest changes have been around storage APIs. He reviews how they have evolved over time, and why they are so important for modern operations.

The current discussion is on VMware Virtual SAN (VSAN) and VVOLs, software features focused on storage within the vSphere hypervisor ecosystem. This seems like a […]
Cormac Hogan of VMware Storage comments: I learnt something interesting about Virtual Volumes (VVols) last week. It relates to the way in which snapshots have been implemented in VVols. Historically, VM snapshots have left a lot to be desired. So much so, that GSS best practices for VM snapshots as per KB article 1025279 recommends […]
Chris Evans of Architecting IT comments: Another VMworld has come and gone and still we haven’t seen the production deployment of VVOLs. Just to recap, VVOLs are the evolution of the packaging of virtual machines that currently reside in data stores. The main benefit is to be able to apply storage performance and availability policies […]
Eric Sloof of NTPRO.NL comments: Virtual Volumes (VVols) is VMware’s new storage paradigm for external SAN/NAS storage arrays. In this session, we will walk you through key technical concepts of Virtual Volumes, in depth. We will also compare in detail some of the existing features in VMFS/NFS with VVols.

With a normal SCSI LUN the underlying storage system has no knowledge of how the upper level operating system, hypervisor, file system or application such as a database (doing raw IO) is allocating the pages or blocks of memory aka storage. It […]
