HPE StoreVirtual – Managers and Quorum

HPE StoreVirtual is a scale-out storage platform, that is designed to meet the needs of virtualized environments. It’s based on LeftHand OS and because the magic is a piece of software, HPE StoreVirtual is available as HPE ProLiant/ BladeSystem-based hardware, or as Virtual Storage Appliance (VSA) for VMware ESXi, Microsoft Hyper-V and KVM. It comes with an all-inclusive enterprise feature set. This feature set provides

  • Storage clustering
  • Network RAID
  • Thin Provisioning (with support for space reclamation)
  • Snapshots
  • Asynchronous and synchronous replication across multiple sites
  • Automated software upgrades and self-healing storage
  • Adaptive Optimization (Tiering)

The license is alway all-inclusive. There is no need to license individual features.

HPE StoreVirtual REST API

Representational State Transfer (REST) APIs are all the rage. REST was defined by Roy Thomas Fielding in his PhD dissertation “Architectural Styles and the Design of Network-based Software Architectures“. The architectural style of REST describes six constraints:

  • Uniform interface
  • Stateless
  • Cacheable
  • Client – Server communication
  • Layered system
  • Code on demand

RESTful APIs typically use HTTP and HTTP verbs (GET, POST, PUT, DELETE, etc.) to send data to, or retrieve data from remote systems. To do so, REST APIs use Uniform Resource Identifiers (URIs) to interact with remote systems. Thus, a client can interact with a remote system over a REST API using standard HTTP URIs and HTTP verbs. For the data transfer, common internet media types, like JSON or XML are used. It’s important to understand that REST is not a standard per se. But most implementations make use of standards such as HTTP, URI, JSON or XML.

Deploying HP StoreVirtual VSA – Part II

Part I of this series covered the deployment, part II is dedicated to the configuration of the StoreVirtual VSA cluster. I assume that the Centralized Management Console (CMC) was installed. Start the CMC. If you see no systems unter “Available Systems”, client “Find” on the menu and then choose “Find Systems…”. A dialog will appear. Click “Add…” and enter the ip address of one of the earlier deployed VSA nodes. Repeat this until all deployed VSA nodes are added. Then click “Close”. Now you should have all available VSA nodes listed under “Available Systems”.

Deploying HP StoreVirtual VSA – Part I

I would like to thank Calvin Zito for the donation of StoreVirtual NFR licenses to vExperts. This will help to spread the knowhow about this awesome product! If you are not a vExpert, you can download the StoreVirtual VSA for free and try it for 60 days. If you are a vExpert, ping Calvin on Twitter for a 1y NFR license.

This blog post covers the deployment of the current StoreVirtual VSA release (LeftHand OS 11). A second blog post covers the configuration using the CMC. Both posts are focused on LeftHand OS 11 and VMware vSphere. If you are searching for a deployment and configuration guide for LeftHand OS 9.x or 10 on VMware vSphere, take a look at this two blog posts from Craig Kilborn: Part 1 – How To Install & Configure HP StoreVirtual VSA On vSphere 5.1 & Part 2 – How To Install & Configure HP StoreVirtual VSA On vSphere 5.1. Another blog post that covers LeftHand OS 11 is from Hugo Strydom. Hugo wrote about what he did with his VSA (vExpert : What I did with my HP VSA). I wrote a blog post about the HP StoreVirtual VSA some weeks ago. If you are interested in some basics about the VSA, check my mentioned blog post.

HP StoreVirtual VSA – An introduction

In 2008 HP acquired LeftHand Networks for “only” $360 million. In relation to the acquiration of 3PAR in 2010 ($2.35 billion) this was a  really cheap buy. LeftHand Networks was a pioneer in regard of IP based storage build on commodity server hardware. Their secret was SAN/iQ, a linux-based operating system, that did the magic. HP StoreVirtual is the TAFKAP (or Prince…? What’s his current name?) in the HP StorageWorks product familiy. ;) HP LeftHand, HP P4000 and now StoreVirtual. But the secret sauce never changed: SAN/iQ or LeftHand OS. Hardware comes and goes, but the secret of StoreVirtual was and is the operating system. And because of this it was easy for HP to bring the OS into a VM. StoreVirtual Virtual Storage Appliance (VSA) was born. So you can chose between the StoreVirtual Storage nodes (HW appliances) and the StoreVirtual VSA, the virtual storage appliance. This article will focus on the StoreVirtual VSA with LeftHand OS 11.
