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 »

The new FlashArray//m platform is touted as a “modular upgradeable architecture” and claims to deliver 50% increase in performance, 2.6-fold increase in storage density and a… Read more »

  • SFD7: Exablox – Scale-Out Object Storage for NAS

    Exablox is one of those companies I’ve followed for some time and it was great to see them presenting at Storage Field Day 7 earlier this year.  The company sells a scale-out NAS platform, supporting the CIFS, SMB and NFS protocols, making it a perfect file server environment for small and medium enterprises. Technology View… Read more »

  • Rumours of Cisco Acquiring Nutanix – Hyper-Converged Consolidation?

    According to Jared Rinderer, via an article that appears in Storage Newsletter, Cisco is on the verge of making a bid to acquire Nutanix, a vendor of hyper-converged systems.  The rumour has been quashed by none other than Nutanix CEO Deeraj Pandey, via an article on The Var Guy website.  In fact, Pandey intimated that… Read more »

  • Why VSAN and VVOLs are Not Software Defined

    Every so often another attempt is made by the vendor community to put a definition to what we call “software defined storage” or SDS.  The current discussion is on VMware Virtual SAN (VSAN) and VVOLs, software features focused on storage within the vSphere hypervisor ecosystem. This seems like a good opportunity for me to review what… Read more »

  • vSphere vDS SPAN port with Wireshark in 2 minutes

    I often find myself searching for facts to dispel “hearsay” and guesswork in troubleshooting discussions between the Network and Windows VM teams.  This article is intended to show just how straightforward it is to use the VMware distributed switch SPAN port capability, to put a virtual sniffer on a virtual port on a virtual distributed… Read more »

  • EMC, ScaleIO and The VMkernel

    There’s been a bit of conversation recently on the intention of EMC to put drivers for their ScaleIO platform into the VMware ESXi hypervisor kernel.  The discussion was triggered by an article published in LeMagIT on 25 November 2014 by Christophe Bardy and subsequently picked up by The Register.  It implied that VMware and EMC were… Read more »

  • What Next for Storage in 2015?

    Sometimes it’s hard to believe that there’s anything more to achieve in data storage.  Surely things are pretty much complete; we have the ability to store vast quantities of data reliably and each year the per unit cost of storage continues to decline.  So as 2015 rolls in, is there anything left to achieve?  What… Read more »

  • NetApp Integrated EVO: RAIL – A Triumph of Marketing Over Common Sense

    I suspect I wasn’t the only one last week who was scratching his head at the latest idea from NetApp which sees them offering a VMware EVO: RAIL solution that incorporates Data ONTAP filer technology.  In case that last statement is unclear to you, yes, NetApp are suggesting that EVO: RAIL, the solution that uses… Read more »
