Setting up a Nimble Secondary Flash Array from scratch

Nimble Storage have released their newest addition in the line up, the SFA, or to give its full name, the Secondary Flash Array. And in this post, we are going to look at how to set one up from scratch.

Taken from the following datasheet;

The Nimble Secondary Flash Array represents a new type of secondary data storage optimized for both capacity and performance. It adds high-performance flash storage to a capacity-optimized architecture for a unique backup platform that lets you put your backup data to work.

The Nimble Secondary Flash Array is optimized for backup, disaster recovery and secondary data storage. By using Flash, it lets you put your backup data to work for Dev/Test, QA and analytics. Instantly backup and recover data from any primary storage system. And our integration with Veeam backup software simplifies data lifecycle management and provides a path to cloud archiving.
Before you get started

As you can imagine it’s as easy as setting up one of the existing Nimble Arrays, as I blogged about previous (Setup via GUI, via CLI). Actually the configuration via CLI is the exact same!

First things to note; the SFA ships with the NimOS 4.x, which is now HTML5 based, and there is extra port requirement for access if you have a firewall or a web proxy in the situ, TCP 5392, which is used for RESTapi access. In my testing, I found that the Sophos web filter that was setup in transparent mode, caused issues with my login page on the Nimble, when I removed it from the equation, I noticed my Firefox gave me a pop-up window as per the below.

Nimble SFA port 5392 e1498081602430

How to setup the array – initial configuration
  • Launch the Nimble Setup Manager, this can be downloaded from https://infosight.nimblestorage.com

You’ll see below I actually used an older version, and it still worked fine discovering the array. When you click next, you’ll be presented a dialog box explaining that your default browser will be launched to continue the setup (as part of the new HTML5 interface).

  • Accept the certificate error, as the Nimble uses a self signed cert on the web interface

VMware vSphere 6.5 Host Resources Deep Dive proof copies

Now available – VMware vSphere 6.5 Host Resources Deep Dive

It’s here!!!

I am sure many of you have been following this technical book closely, the latest publication by Frank Denneman. And now its available to order!!!!  There is already a fantastic opening statement wrote by Duncan Epping today as the book is officially published.

The book focuses on four key physical host component areas, and doesn’t touch VMware software features in-depth such as HA and DRS, only the host resources;

  • CPU
  • Memory
  • Storage
  • Network

As can be seen by the striking cover below.

VMware vSphere 6.5 Host Resources Deep Dive front cover

If you haven’t already, I recommend that you give the @Hostdeepdive twitter account a follow, or at least a browse through to see some of the snippets released.

If you have read the VMware vSphere Clustering Technical Deepdive books, you already know what to expect in terms of technical level of content, however the sneak peaks show that Frank and Niels have gone even deeper than you can imagine.

See the below example,

I’ve been tracking this publication closely, and wished I could have been a reviewer, but i now have my copy on order, so expect a review soon!

Where to buy?

Below are the links from everyone’s favourite retailer to purchase the paperback copy, I believe that eBook available should be after VMworld;

Amazon Book Blurb

I couldn’t really write this up better than whats on amazon;

 The VMware vSphere 6.5 Host Resources Deep Dive is a guide to building consistent high-performing ESXi hosts. A book that people can’t put down. Written for administrators, architects, consultants, aspiring VCDX-es and people eager to learn more about the elements that control the behavior of CPU, memory, storage and network resources.

This book shows that we can fundamentally and materially improve the systems we’re building. We can make the currently running ones consistently faster by deeply understanding and optimizing our systems.

The reality is that specifics of the infrastructure matter. Details matter. Especially for distributed platforms which abstract resource layers, such as NSX and vSAN. Knowing your systems inside and out is the only way to be sure you’ve properly handled those details. It’s about having a passion for these details. It’s about loving the systems we build. It’s about understanding them end-to-end.

This book explains the concepts and mechanisms behind the physical resource components and the VMkernel resource schedulers, which enables you to:

    Optimize your workload for current and future Non-Uniform Memory Access (NUMA) systems.
    Discover how vSphere Balanced Power Management takes advantage of the CPU Turbo Boost functionality, and why High Performance does not.
    How the 3-DIMMs per Channel configuration results in a 10-20% performance drop.
    How TLB works and why it is bad to disable large pages in virtualized environments.
    Why 3D XPoint is perfect for the vSAN caching tier.
    What queues are and where they live inside the end-to-end storage data paths.
    Tune VMkernel components to optimize performance for VXLAN network traffic and NFV environments.
    Why Intel's Data Plane Development Kit significantly boosts packet processing performance.

Finally to round off, here is one of my recent favourite tweets from Frank, that I’ve also been sharing around work.

Video Blogs I appeared on at #VeeamON

Whilst attending VeeamON conference in New Orleans I had the chance to speak on two different video logs, three recordings.

  • Tim Smith – Tim’s Tech Thoughts
  • Dave Kawula MSDN – Channel9 page

First up Ransomware Talk with fellow Veeam Vanguards – Covering the big topic of the week ransomware, as the title states.

Second the first Channel 9 episode

Episode 64 – Interview with Dean Lewis at VeeamON 2017 – Covering what we are looking forward to at the VeeamON conference, the growth and important of Office365.

And then last, a follow up episode on MSDN Channel 9.

Episode 70 – Interview with Dean Lewis at VeeamON 2017 – another chat around Ransomware, Veeam VAO, the importance of documentation and finally things to think about when testing your DR environment and failover plans.

#VeeamON 2017 Announcements – Now the dust has settled

The dust settled as my aeroplane wheels landed at Heathrow on Saturday 20th May. VeeamON. So now its time to digest, and detail the information from the worlds premier availability conference, VeeamON.

Veeam is now 10 years old! So its out with the old and in with the new logo!

Veeam old new logo

It’s hard to believe that the logo on the left has been knocking around for so long.

So lets dive into the announcements.

Veeam Backup and Replication v10;
  • NAS Backup – the support for backing up File Shares and NAS devices, and the ability to restore point in time file versions, or file share state.

Veeam v10 Backup Nas Storage Settings

  • Continuous Data Protection (CDP) – utilizing VMware’s vSphere API for I/O Filtering (VAIO) (meaning no snapshots), Veeam has built upon its technology to allow for data protection down to seconds, rather than minutes. The feel and look of the UI settings are that akin to the replication features. Unlike competitors, there is no need for agents inside your virtual machines, or unsupported changes to your VMware environment.

Veeam v10 CDP Settings

  • Full support for physical devices – customers cried out, Veeam listened. There is a need to protect physical workloads, Veeam first produced Endpoint Backup as a free product. Then added enterprise sauce ontop which included support. Now you can fully control your agent backups via the Veeam Backup and Replication Console, including automated deployment. Protect your Workstations, Servers and Failover Clusters.
  • Scale-out Repository Archive Tier – Providing you the ability to send your backups to cheaper storage (think online; Amazon S3, Amazon Glacier, Azure Storage Blobs). With a varying degree of options around thing, its easier to control your sprawling GFS setups, and makes it easier to keep a tight control of data which needs to be retained for a number of years.

Veeam v10 Scale Out Repository Archive Tier Amazon S3 Glacier Azure

  • Oracle RMAN support – allowing users to seamlessly stream RMAN backups into Veeam repositories and easily perform UI-driven restores from backups using a Veeam console.
  • Enterprise Manager enhancements – role-based access control to establish self-service backup and restore functionality for VMware workloads based on vCenter Server permissions.

I attended a session with Anton Gostev, no introductions needed, who was providing a deep dive on v10. You can see the recording below.

HP IMC 7.2 – won’t backup config of Cisco Nexus 9K switch

Background

I have a customer who is using HP Intelligent Management Center (IMC) to monitor their switching environment. Originally they were using all HP Switching, but have slowly moved away during a refresh cycle and now use Cisco Switching, a mix between 2960X and Nexus switching.

The issue

When changing the HP IMC (Basic edition licence) over to manage the Cisco switching, everything went fine, apart from the Nexus 9K switches, which were not detected properly nor could be backed up. We contacted HP, who said the 9K switches are supported, but they would not give us any further details until we had a software support contract in place.

When we ran a manual backup of the switch we would receive the following error message;

Failed to send the configuration file from the device to the iMC Server by TFTP
HP IMC Cisco Nexus switch failed backupHP IMC Cisco Nexus switch failed to send configuration file from device
The cause

The cause is down to the sysOID seen by IMC, it correctly see’s the vendor a Cisco switch, but does not identify it as a Nexus switch. The default settings for a Cisco Switch in IMC is to use CatOS commands for any operation.
