Dell Logo

Nutanix does not need presentation: it’s one the first example of hyper-converged storage architecture and probably one of the most know (for an overview see this post).

Dell also does not need any presentation and their storage portfolio has some interesting products, included PowerVault MD (based on NetApp technologies), other PowerVault products, EqualLogic and Compellent solutions.

This week Dell announced is new partnership with Nutanix to provide a new series of their converged appliance built on Dell servers and powered by the Nutanix software extending Dell’s SDS portfolio. This is another step for Dell into the hyper-converged solutions for the web-scale market (there were already other OEM partnership).

VMware Virtual SAN (or VSAN) is a Software Defined Storage solution from VMware that also fits in the hyper(visor)-converged model. Although is a separate product, the core functions to implement it are already present in the vSphere 5.5 U1 version making really easy to deploy and enable it.

Also the HCL is mainly the same from vSphere 5.5, but some requirements and special considerations must be considered before implementing a VSAN solution.

You can start from the scracth buy scratch your hyper-converged architecture, or you can directly bought a Virtual SAN ready nodes (minimum 3 for start).

Starting from vSphere 5.0, the vCenter Server Virtual Appliance (vCSA) is a new deployment options with some pros and cons. Some of the cons may limit it in the large environments, but starting with the version 5.5 the embedded database has more interesting limits to make it suitable for most of the SMB cases.

Honestly I like the idea to have a vCenter Server as a single black box: it make simple to manage and backup it. But also to update (update vCSA is really faster compared to update a tradition vCenter Server).

Anyway there are also some minor issue that you have to take care during your deployments.

VMworld-Logo

Like in the past VMworld 2013, this year the location of VMworld 2014 will be again San Francisco (for the US edition) and Barcelona (for the EU edition).

  • US edition: will be in San Francisco during August 24-28 2014 (with a partner day on 24)
  • EU edition: will be in Barcelona during October 14-16 2014 (with a partner day on 13)

Registrations for the US event are already open (with the early bid that will close on Jun, 10; for the EU edition will close on Jul, 29). For the pricining and the discount see this page (or this for the EU event).

VMware Press

I’ve got the opportunity to read one of the few book about the Horizon Workspace solution: VMware Horizon Workspace Essentials from Peter von Oven, Peter Bjork and Joel Lindberg.

This book came from a different editors, compared to most of the VMware related books (from VMware Press) that is Packt Publishing and has several interesting books (really a lot on virtualization and still growing).

A written this is one of the few resources (or the only one?) about VMware Horizon Workspace that is a really interesting product, but with not so much labs, course and material compared with other products.

After the announce of some months ago, VMware Horizon View 6 has been released for general availability (GA). The name has also sligtly changed in VMware Horizon (with View) 6.0, considering that the previous Horizon Suite is no more avilable.

Editions are also little different: Horizon 6 (with View) is sold in three editions, VMware Horizon™ View™ Standard Edition, VMware Horizon™ Advanced Edition, and VMware Horizon™ Enterprise Edition.

CloudOps-SIG

CloudOpsSigAfter (several months) after the last CloudOps events, the CloudOps VMUG SIG will organize a new event on the integration between OpenStack and VMware

This webinar will be similar to the presentation of Salvatore Orlando (VMware Engineer) at the previous VMUG IT User Conference. Salvatore Orlando will present (this time in English) also this time. Don’t miss him.

SanDisk-Logo

Chipmaker SanDisk Corp said it would buy the well know flash storage device maker Fusion-io Inc for about $1.1 billion.

With this move SanDisk can doubled down on its strategy to target the enterprise and data centers, considering that Fusion-io is already used in the enterprise, with really big customers like Apple and Facebook.

SanDisk is probably know more for the consumers products (lot of flash memory card are from this vendor), but has several interesting products also for the enterprise (see this post about their caching product).

Veeam-Logo-2014

Veeam Software announced (on 11 June) a new part of the new Veeam Availability Suite v8, called Veeam Cloud Connect.

The new functionality is designed for Veeam Cloud Providers (VCPs), both current VCPs and new service providers, and gives an easy way to host backups for Veeam’s customers. Veeam customers get a fully integrated, secure and efficient means to move backups to an offsite backup repository managed by the service provider of their choice, but without the upfront capital investment of an offsite infrastructure.

Nutanix-NoSAN

Hyper-converged architectures consolidate and manage computing, networking, and storage resources via software so they can run on any vendor’s server hardware.

Several years ago they where (apparently) strange approach to storage implementation used mainly for cheap solution (using VSA, that lacks, in much cases, of right scalability), or for special user cases like ROBO or VDI (with solution like NexentaVSA for View).

But starting with Nutanix (probably the first real player in those kind of solution) the idea of simple VSA (Virtual Storage Appliance) has dramatically changed by introducing a large scalability with new scale-out (or web-scale, using Nutanix terms) approach.

Storage-Frondend-Backend

In an old post about storage architectures is described in a simple way some basic concepts, including the scale-in (or scale-up) vs. the scale-out approach. They are different approaches in scaling with different implications.

Unfortunately there is a simple an well accepted definition on what is a scale-out storage is (or not is): some are limited in specific contests (like this one only for NAS or this SNIA tutorial still applied to a NAS storage), other are too much vendor specific.

But usually a scale-out storage imply:

  • Multi-device (or multi-array) storage systems (aggregated in a pool of resources)
  • Possibility to scale both in capacity and in performance
  • Unified management and usually also a unify view of a single logical storage
  • Some kind of fault-tolerance or high availability or data protection across the systems

Infinio-Logo

Some days ago (June 3, 2014), Infinio has announced a change in executive board with an important new entry: Scott Davis, former VMware CTO (storage and end-user computing divisions), joins Infinio as CTO. Infinio founder Vishal Misra (previous CTO), moves to the newly created role of Chief Scientist. Misra is also a professor in the Computer Science department at Columbia University.

Infinio has a really interesting storage acceleration product (see this post for the 1.0 version, but actually we are at 1.2 version) with a really innovative approach. Let’s see how this changes will accelerate Infinio company.
