Gluster blog stories provide high-level spotlights on our users all over the world
I’ve spent a significant amount of time recently swatting up on EMC’s new VMAX Cloud Edition. It has to be said that this looks like one of the most interesting storage announcements I have seen in a long time. In fact I have a project coming up that I think it may well be a perfect fit for.
First a massive thanks to EMC’s Matthew Yeager (@mpyeager) who answered a couple of questions I had. He really went the extra mile to clarify a couple of things and the video he made is well worth a watch. Also Martin Glassborow (@storagebod) has interesting things to say as well.
This is a product that could put a lot of people out of a job. If you are the sort of person who likes to keep hold of your little castle’s of knowledge then you will not like this from what I can see. Finally we are able to be truly customer focused, balancing cost, performance and capacity to give them exactly what they want. EMC claim this is a world first and to my knowledge they are right.
Storage architects put a lot of time and effort in to tweaking quotes and systems to balance price, capacity and performance for a given work load. However, most of this is just reading up on the best-practises for a given array and situation and applying them. There is nothing that clever to it – reading and practise is what it comes down to. However, it has alway been as much an art as a science because an individual architect does not have a very large dataset to refer to. On the other hand EMC have got 60 million hours of metrics across more than 7000 VMAX systems out in the field. With that amount of data the amount of art involved diminishes and it becomes purely a science.
What you get is a VMAX 10k, but instead of defining storage pools, tiering policies, RAID levels etc you balance 3 facters: Space, performance and cost. Need a certain performance level for a certain amount of space no matter the cost? Just dial it in and mail EMC a cheque. Have a certain budget, need a certain amount of space, but performance not a problem? Same again.
No longer will we be carefully balancing the number of SATA and FC spindles and the types of RAID level. No longer will be worrying about what percentage of our workload we need to keep on the SSD layer to assure the necessary number of IOPS. We will not even be calculating how much space we have after the RAID overheads.
That is all very interesting, but so far it is just a new approach to the UI. It is an excellent approach, but nothing especially clever. One of things I gravitated towards was the white paper about integrating with vCloud. Despite it being geared toward VMware (I wonder why? – not!) the principles equally apply to any situation where automation is required. I am a huge DevOps fan (Puppet in particular). Storage arrays have never been particularly automation friendly. In addition to the cloud portal, the VMAX CE also has a RESTful API. Now that is awesome! Here we have the abilty to easily integrate a VMAX with the likes of OpenStack Cinder, Puppet, Libvirt, or whatever you want.
Finally Chad Sakac informs me that VMAX CE is just the first. EMC intend to roll this management style out to other product lines. Personally I think this would suit both Isilion and Atmos lines very nicely.
I am really excited about this product. It brings a paradigm shift in storage management and automation. Also I am led to believe that the price is exceptional as well, to point that it seems EMC may even be pushing VNX down a market level (to where it should be perhaps?). I have been a bit nasty to EMC in the past, but recently they are doing some stuff that has really got me interested. This and Razor are 2 projects that are definitely worth keeping an eye on.
2020 has not been a year we would have been able to predict. With a worldwide pandemic and lives thrown out of gear, as we head into 2021, we are thankful that our community and project continued to receive new developers, users and make small gains. For that and a...
It has been a while since we provided an update to the Gluster community. Across the world various nations, states and localities have put together sets of guidelines around shelter-in-place and quarantine.

The initial rounds of conversation around the planning of content for release 8 has helped the project identify one key thing – the need to stagger out features and enhancements over multiple releases. Thus, while release 8 is unlikely to be feature heavy as previous releases, it will be the...
