About scale-out storage ARM-ification… and $/GB

I came across two interesting news items this week – OpenIO introducing a 96-HDD appliance for its object storage platform and Western Digital launching 12 and 14TB disks! At first glance if you sum the two, it’s like crazy: just think about a single 96-slot appliance full of 14TB disks, which means 1.3PB in a 4U box, or 13PB in a datacenter rack. Again, it sounds crazy but in reality it’s totally different and it is absolutely brilliant! Is a 14TB HDD too big? 14TB is a lot (the 12TB is based on PMR technology while the 14TB is...

Two case studies on object storage

Last month I did some work with Caringo and a couple of their customers, Texas Tech University in the US and NEP in Europe. Totally different stories, but two of the most classic use cases for object storage: the first is about storage consolidation with distributed NAS front-end, while the latter is on smart and high performance CDN backend. I love talking to end users to find out how their choices pan out when it comes to infrastructure design and how they experience day-to-day system administration. The two documents are not particularly long, (for marketing reasons), but I think...

Who needs traditional storage anymore?

The traditional enterprise storage market is declining and there are several reasons why. Some of them are easier to identify than others, but one of the most interesting aspects is that there’s a radicalization in workloads, hence storage requirements. Storage as we know it, SAN or NAS, will become less relevant in the future. We’ve already had a glimpse of it from Hyperconvergence, but this kind of infrastructure is trying to balance all the resources – at the expense of overall efficiency sometimes – and they are more compute-driven than data-driven. Data intensive workloads have different requirements and need...

It’s hard being HPE these days

I’m sitting here in the blogger lounge at HPE Discover 2016, in London (while also keeping an eye on the news coming from AWS Re:Invent in Las Vegas)… and the only thing that comes to my mind at the moment is something I read on twitter a few days ago: “the software is eating the hardware and the cloud is eating the software”. More Focus, but… HPE is much more focused than a year ago (thanks to the split from HP Inc.) and are trying to remain relevant in a world that has been seeing a major change on...

Serverless-enabled storage? It’s a big deal

The success of services like AWS Lambda, Azure Functions or Google Cloud Functions is indisputable. It’s not for all use cases, of course, but the technology is intriguing, easy to implement and developers (and sysadmins!) can leverage it to offload some tasks to the infrastructure and automate a lot of operations that, otherwise, would be necessary to do at the application level, with a lower level of efficiency. The code ( a Function) is triggered by events and object storage is perfect for this. Why object storage Object storage is usually implemented with a shared-nothing scale-out cluster design. Each...
