Comments off

Reading Time: 3 minutesOn February 16th 2016, EMC has launched a new product: VxRail. It’s a fully integrated, preconfigured, and pre-tested VMware hyper-converged infrastructure appliancebased on VMware’s vSphere and Virtual SAN, and EMC software. VxRail delivers an all-in-one IT infrastructure transformation by leveraging a known and proven building block for the Software Defined Data Center (SDDC). But more important is not only an EMC product: it cames from the VCE that is an alliance with EMC, VMware and Cisco. So it’s mainly an EMC and VMware new product.

Reading Time: 2 minutesNote: on 24 July 2020, OVHcloud acquired OpenIO! OpenIO is a startup founded in 2015 by a team of 7 co-founders, experts in mail and data infrastructures. The headquarter is located in Lille, France, and there is also an OpenIO office in San Francisco. They start with the need to to store huge amounts of relatively small files produced by end-users like emails, eventually using a large storage capacity, but always accessed with the lowest latency. Also, there was the need for maximum availability as Service Level Agreements were stricts for these critical end-user services. Object storage can […]

Reading Time: 5 minutesNote: the company has closed all operations on January 2018. Primary Data emerged from stealth November 19, 2014 and I was lucky enough to met them one year ago (see #ITPT 14 Report – Primary Data) and learn about their interesting vision of storage virtualization. Primary Data’s product has been officially announced during VMworld US 2015. Its headquarter is in Los Altos, CA with offices around the world and currently employs about 80 staff worldwide and with over $60 million in venture capital raised to date.

Frame vs. frame-less storage

28 July 2015
Comments off

Reading Time: 2 minutesOne old (and now quite not used anymore) storage concept was about the Frame vs. frame-less architectures. Those terms are from the past decades and where used (especially from Dell-EqualLogic) to identify how storage controllers are dedigned and how they can scale: Frame-based storage contain individual components that scale independently (you can add more cache, network connections, disks, software, etc.) until it’s maxiums and until the product is still supported. Usually you have two storage controllers and one ore more shelves of disks. Frame-less storage is modular where each “module” include it’s own storage processors, […]

StarWind Virtual SAN: a scale-out storage that works also with 2 nodes

Reading Time: 8 minutesStarWind Software is a US privately held company (headquartered in Wakefield, Massachusetts, USA) which began in Feb 2009 as a spin-off from Rocket Division Software (founded in 2003), with its StarWind iSCSI Target solution as main product. After that, the company has grown and also the products have evolveld following the market trends and customer needs. Now their most interesting product is StarWind Virtual SAN: a scale-out and “shared-nothing” storage solution that works also with 2 nodes, configuration that can be really important for remote office and branch office (ROBO) or SMB cases.

Not all Virtual Volumes are the same

Reading Time: 4 minutesVMware Virtual Volumes (or VVols) are a new important features of vSphere 6.0 that could be really important for storage vendors, because they permit to convert external storage in VM-aware storage. It could be really useful for block based storage, but also for NFS storage it can be used to provide a complete per-VM granularity, policy based management and integration with specific storage services:

What are Erasure Coding and RAIN?

26 June 2015
Comments off

Reading Time: 4 minutesWhen you talk about data protection against hardware failure in storage system, probably RAID (Redundant Array of Independent Disks) is the first technology that you think. RAID could be hardware or software based, and in the second case it can be implemented (with functions similar to RAID, but not necessary the same) also at the filesystem level (think about ZFS, for example). But with the new hard disk drive (HDD) capacities edging upwards (6TB HDDs are now available) the traditional RAID is becoming increasingly problematic both for the rebuild time and the bottleneck related to each single […]
