Windows Server, Release Cycles and HCI

The discussion on Storage Spaces Direct (S2D) seems to have generated a lot of interest and a lot of defensive posts. These posts seem to think that what has been written is either wrong or misinformation.  Actually, the issue is poor communication on Microsoft’s part.  However, what’s subsequently been said has left more questions than… Read more »

What Happened to Storage Spaces Direct?

Can this article on The Register be true?  Has Microsoft removed Storage Spaces Direct from the latest Windows Server build? To be honest I’d initially not given this article much thought until I decided to have a look at the latest Windows Server build myself.  I was interested to find that I can’t actually download… Read more »

Block is Not the Solution for Persistent Container Storage

It appears we’re reaching a consensus that persistent storage is needed for containers.  Despite early resistance, with an assumption that containers and their data should be transient, the logic of data persistence is starting to take hold.  To be honest it simply makes sense. Yes, I could keep my data in sync between multiple nodes… Read more »

Can Violin Systems Successfully Rise from the Ashes of Violin Memory?

I recently met up with the CEO of Violin Systems, Ebrahim Abbasi, for a chat about the industry and the future of the company.  Those who knew Violin Memory will be familiar with this company as it is essentially the assets and IP of the failed Violin, acquired by the Soros Group and relaunched as… Read more »

That 100TB Drive Is Closer Than You Think

Another day goes by and we have another story about hard drive technology.  Yesterday, Western Digital held a media event (I wasn’t invited) to announce MAMR, the latest technology for improving hard drive density.  MAMR stands for Microwave Assisted Magnetic Recording and is a process to increase the stability of recording with very small grain… Read more »

Fixing the Problem of I/O With Parallel Computing – DataCore MaxParallel

The idea of improving the performance of applications through the use of parallel computing isn’t a new concept.  Look back 50 years and we can see that Amdahl’s Law shows how to predict the performance improvement that can be achieved by using multiple processors.  You can find details of Amdahl’s Law on Wikipedia, but essentially… Read more »

It’s Time for Hard Drives to Join Tape In The Archive Tier

This week we’ve seen the announcement of 14TB 3.5” hard drives from one vendor and 12TB from another. It’s hard to imagine the concept of 14TB in a single hard drive when ten years ago we were looking at only 1TB devices. However, these devices have a problem. The throughput and latency has remained relatively… Read more »

Azure Enterprise NFS by NetApp – Initial Thoughts

One of the big announcements coming out of NetApp Insight in Las Vegas is the release of Microsoft Azure Enterprise NFS Service using Data ONTAP technology.  The idea that a cloud hyperscaler could use a mainstream technology for storage instead of building their own is unique enough, but the more interesting scenario is the ability… Read more »

Scale Computing Debuts HC3 in Google Cloud Platform

Hyper-converged infrastructure is a great technology for running a range of mixed workloads.  With HCI how do you manage DR?  Typically the standard solution might be to run up another cluster in a separate data centre and run both 50% active/active or have one purely for standby.  What about running in the public cloud?  With… Read more »

Qumulo Releases QF2 – A Cross-Cloud Scale-Out File System

Over the last few weeks, I’ve talked a lot about data mobility and exactly how we should get data into the public cloud from on-premises locations.  You can find links to the posts at the end of this blog entry.  Much of what I’ve talked about revolves around moving data in a relatively static way,… Read more »

  • Conflating Reliability and Endurance in SSDs

    Last week I sat through a presentation by Samsung on the evolution of their DRAM and flash business. One question raised by a journalist in the room related to the reliability of flash drives. The presenter proceeded to talk about the industry and how endurance means flash has a finite lifetime, one which now varies… Read more »

  • Dell Acquiring EMC – The Federation

    This is the second of a series of posts on the pending acquisition of EMC by Dell. One of the biggest features of the modern EMC has been the idea of a federation of independent businesses, established when EMC acquired VMware in 2004 (although public shares weren’t released to the market until 2007). EMC (more… Read more »

  • Dell Acquiring EMC – The Facts

    As I’m not a journalist, I don’t have a need to leap in and make commentary when big announcements/acquisitions are made. Instead I’ve taken the time to look at all of the comments already out there and formulate a more considered opinion. I doubt the acquisition of Dell by EMC has escaped most people’s attention… Read more »

  • PernixData FVP – Feature or Platform?

    A couple of weeks ago I was briefed on the latest technology to come out of PernixData; a software suite known as Architect, which provides insight into the I/O workload of virtual machines in a VMware vSphere environment.  The company’s previous (and still current) product is FVP, a caching software layer for the hypervisor that… Read more »

  • Standard SSDs or Custom NAND Modules?

    At VMworld last week I took part in a Tech Field Day presentation from Violin Memory, one of the earliest all-flash array start-ups.  Violin are “relaunching” the company, following on from many senior management changes and a lot of work to make their products more relevant.  One point of discussion (specifically from me) was whether… Read more »

  • Kaminario Releases K2 v5.5 With $1/GB Price Point

    Last week Kaminario Inc, a start-up vendor of all-flash storage solutions released an upgrade to their K2 platform.  The release, introduces three main new features: 3D TLC NAND, achieving a $1/GB price point (usable). Native data asynchronous replication, based on snapshots. A feature called “Perpetual Array” to take some of the operational and financial cost… Read more »

  • Flash Economics: Choosing The Right SSD

    This post first appeared on the Kaminario Blog – http://kaminario.com/blog/flash-economics-choosing-right-ssd/ At a superficial level, it’s easy to assume that all solid-state disks (SSDs) are the same. In reality, that assumption couldn’t be further from the truth. SSDs continue to evolve and are dividing into a broad product category, in much the same way that hard disk… Read more »

  • Avoiding The Forklift Upgrade – Kaminario Guest Post

    I’ve recently started working with Kaminario, an all-flash array startup vendor and will be publishing a series of posts and papers on the Kaminario site.  I’ll also be linking them here for convenience.  The first post covers scale-out architectures as a way to avoid the continual replacement of technology – the so called forklift upgrade….

  • Nutanix Goes After Private Cloud with XCP

    This week Nutanix held their .NEXT conference in sunny Miami, around plenty of anticipation for what was to be announced.  In the hyper-converged market-place there’s not a lot of love lost between the incumbents like VMware and the upstarts like Nutanix, as can be seen from recent blog posts that play on the polarisation of… Read more »
