Open vStorage - Open Source SDS

Open vStorageI recently came across an exciting technology called Open vStorage from CloudFounders that provides an abstraction layer between the storage presented to the virtual machines and the backend object storage.  

This abstraction layer provides the following functionality:

Converged Storage - Some Available Options - Part 2

This is the second part of a two part article on converged storage solutions.  Part 1 is here.  Part 1 dealt with vSphere VSANEMC ScaleIO,​ Atlantis ILIO USXStorMagic SvSAN and Maxta SDS.  In this second instalment I'll try to consisely summarise:

Centos 6.5 NFS Server Suitable for Cloudstack

Centos​In the past I have had the odd bit of difficulty with getting Cloudstack to work with a freshly built NFS server as either primary or secondary storage.

CEPH - Highly Scalable, Open Source, Distributed File System

CEPH is perhaps one of the most talked about open source object storage projects, especially now that it can be used in OpenStack for primary (cinder - volume) storage as well as secondary (glance - image) storage.  This technology summary attempts to provide you with as much relevant information as possible in the shortest number of words.  Here are some of the most important features of this up and coming object store.  

For further information please refer to the Credits and links collapsible section below.  There you will find links to documentation and companies that offer support services for this product.  At a later stage I will write a similar piece on GlusterFS, which is, rightly or wrongly, compared to CEPH.

Converged Storage - Some Available Options - Part 1

Converged storage options for the various hypervisors appear to be increasing.  The coverage in the press is also on the up, causing customers to review this technology as their data centre storage requirements grow.  This type of storage solution does not suit every set of requirements but it can offer some compelling advantages:

30 Minute Introduction to Openstack Architecture

OpenStack Arhitecture ​If you are just starting out in the wonderful world of OpenStack but are not sure where to start, take a look at this Youtube presentation by Sandy Walsh.  Sandy is an OpenStack core developer with Rackspace.  It will help if the viewer has some familiarity with cloud concepts but it is not essential.

VSA Storage

Virtual Storage Appliance.  This term is often used when talking about converged storage solutions, that is where storage and compute are combined onto a single device (or most probably, a collection/cluster of devices).  In that context, it often means a virtual appliance (lean Linux installation with bespoke storage application included) that resides on a hypervisor and virtualises the local hypervisor's storage, combining it with the storage of other devices in the cluster, and presenting it over NFS or iSCSI back to the hypervisor.  This type of server-local disk virtualisation can bring with it huge cost savings when compared to traditional SAN infrastructure.  In short, it is a... more
