A Brocade firmware upgrade once in a while is highly recommended: new releases usually squash bugs and add new features, which helps with a stable and efficient SAN infrastructure. The upgrade process itself is relatively straightforward if you keep in mind that you can only non-disruptively upgrade one major release at a time. With that knowledge you only need a FTP server (like Filezilla), SSH client (PuTTY), the upgrade packages and some patience.
According to Tintri, the rise of server virtualization broke the traditional storage system. Initially we had relatively simple environments where one server talks to a number of LUNs on a storage system. Sometimes we’d have a small cluster of servers accessing those volumes. Still relatively simple.
Fast forward to now: large clusters of hypervisor hosts are the norm, collectively accessing an even larger number of volumes. Each hypervisor in turn hosts a large number or virtual machines. In case of performance problems, how are you ever going to figure out the root cause and which other systems are affected?
Datera was founded in 2013 with a clear mission: bringing hyperscale operations and economics to the private clouds. The big corporations such as Facebook and Google don’t manage individual pieces of hardware. Instead they use policies and “the system” will decide where to spin up an app or place some data. This means an admin can manage a lot more servers or storage. So why is this level of automation only used by the big corporations? Datera aims to change that!
Storage Field Day 11 is taking place on October 5th to 7th in Silicon Valley, and I’m delighted to report: I’ll be one of the delegates again. In fact, this will be my 5th event! Wouldn’t it be awesome if British Airways reads this blog and hands me some champagne to celebrate as soon as we’re in the air…
The Tech Field Days are organized by GestaltIT and follow an efficient concept. A number of companies are invited to present to a number of picked individuals (delegates) and the 2 hour sessions are broadcasted live over the interwebs. The sessions are very interactive: delegates will be asking questions throughout these presentations. People back at home can ask their questions on Twitter (don’t forget the hashtag, which is #SFD11 for this event), and usually one of the delegates will pick it up and voice it towards the presenters.
Earlier this year Nimble Storage announced their all-flash array called the Predictive Flash Platform; you can read my thoughts on the launch over here. InfoSight is one of the core components of that announcement, which is why we had the opportunity for a fireside chat with the Nimble Storage data science team. We discussed the workings of InfoSight & VMVision and how this relates to actual benefits for an owner of a Nimble Storage array. This post will also touch on some of the key points discussed during the later Storage Field Day 10.
I will be attending Dell World this October in Austin, Texas and will be trying to find out how the merger between these massive companies will impact the Dell and EMC storage product portfolios. Flying in under the EMC Elect program, we should be having a front row seat to all the exciting announcements!
A couple of weeks ago StorMagic announced their newest SvSAN 6 release. The basics are still the same: SvSAN takes the internal disks from two hypervisor servers (HyperV or VMware) and turns them into highly available shared storage. Yes, that’s a two server minimum, not three; so this should be a little bit cheaper compared to VMware VSAN and the likes. What’s new in version 6 is the addition of an Advanced edition with SSD and memory-based caching and tiering.
Question: What do you get when Pure Storage gets to build a system that can start small, grow big, handle file requests quickly and is simple to manage?
FlashBlade: Pure’s newest addition to its hardware portfolio. The Pure Storage FlashBlade is not just another NAS filer. It’s an all-flash, scale-out storage for file (NFSv3 for now) and object (soon), delivering some pretty good performance as you can see in the sheet above. And the chassis just looks sexy…
If you want to build a private S3 object store, Cloudian HyperStore might be the product for you. Using commodity servers to form a scale-out architecture, you can build your own, fully S3 compliant object storage that’s located in your own datacenter. If you don’t want to supply your own servers, you can opt for the Lenovo Storage DX8200C appliance, powered by Cloudian!
I had the opportunity to play with a new EMC product last week: ScaleIO. It’s definitely not a new EMC product (I troubleshooted the 1.31 version and EMC released 2.0 at EMC World 2016) but I just hadn’t had the honor to work with one of those systems yet. ScaleIO is a software-defined storage solution that uses the local disks in your commodity server and shares these out as block LUNs across the Ethernet. Which means this architecture can scale pretty well, both on capacity and performance, using hundreds (if not thousands) of servers and disks.
