In the third part of the SmartOS Series (check the first two parts: Intro and Virtualisation) we are going to deep dive into the SmartOS Storage: ZFS. ZFS is a combination of file system and logical volume manager originally introduced in Solaris 10. ZFS includes many features that are key for a Cloud OS such […]
Last week we started a new blog post series on SmartOS. Today we continue in this series and explore in details the virtualisation aspects of SmartOS. SmartOS offers two types of OS virtualisation: the Solaris-inherited container-based virtualisation, i.e. zones, and the hosted virtualisation ported to SmartOS by Joyent, KVM. Containers are a combination of resource […]
In the first part of the Distributed File Systems Series we gave an introduction to Ceph. Today we will explore another file system: GlusterFS. GlusterFS is a clustered network filesystem that uses FUSE and that allows to aggregate different storage devices, bricks in GlusterFS terminology, into a single storage pool. The storage in each brick is formatted […]
Some time back we introduced a piece of work that we are working on: OpenStack on SmartOS. Today we start a new blog post series to dig into SmartOS and its features. We’ll start with a quick introduction to SmartOS to get everyone started with this platform. SmartOS is an open source live operating system mainly […]
With this post we are going to start a new series on Distributed File Systems. We are going to start with an introduction to a file system that is enjoying a good amount of success: Ceph. Ceph is a distributed parallel fault-tolerant file system that can offer object, block, and file storage from a single cluster. […]

SmartOS is an open source type 1 hypervisor platform based on Illumos, a descendant of OpenSolaris, and developed by Joyent. SmartOS is a live operating system, meaning that can be booted via PXE, USB or an ISO image, and runs entirely from memory, leaving the full space on the local disk to be used for virtual machines. This type of architecture makes SmartOS very secure, easy to upgrade and recover. Given its performances and reliability, in the context of the Mobile Cloud Networking project, SmartOS has been chosen to support telco-grade workloads and provide carrier-grade performances.
Description Distributed File Systems are file systems that allow access to files from multiple hosts via a computer network, making it possible for multiple users on multiple machines to share files and storage resources. Distributed File Systems are designed to be “transparent” in a number of aspects (e.g.: location, concurrency, failure, replication), i.e. client programs […]
Description Virtualisation is at the core of Cloud Computing and therefore its performance are crucial to be able to deliver a top-of-the-class service. Also, being able to provide the adequate virtualised environment based on the user requirements is key for cloud providers. SmartOS, a descendant of Illumos and OpenSolaris, presents features such as containers and […]
