Dell EMC’s PoewrMax is the latest in a long lineage of tier zero storage, going all the way back to EMC Symmetrix. Arjan Timmerman looks at the latest updates with PowerMax that he saw at Storage Field Day earlier this year, and considers why it continues to resonate with very large customers for so long.
Perception vs. Reality in Storage Performance
Todd Mace of cloudjock.com writes the following: This dichotomy I find fascinating as I think it also relates to the smartphone industry. For example, when I upgraded to the iPhone 6, I immediately noticed a performance increase; however after several weeks of use, I wasn’t aware of the performance increase, as I became accustom to […]
VMware VVOL’s and storage I/O fundamentals
Greg Schulz has a great post on his StorageIO blog about VMware VVOL’s. With a normal SCSI LUN the underlying storage system has no knowledge of how the upper level operating system, hypervisor, file system or application such as a database (doing raw IO) is allocating the pages or blocks of memory aka storage. It […]
Nutanix Networking — Quick Tip
Seb Hakiel of vWired.co.uk gives a quick tip on the Nutanix network resiliency: This seems to be resilient, however I discovered (whilst reading documentation, not through hardware failure) that the 2 x 10GigE ports actually reside on the same physical card, so this could be considered a single point of failure. To work around this […]

Introduction to Openstack Storage Systems
Paul Meehan gives an introduction to Openstack Storage Systems on virtualizationsoftware.com: Openstack should present an opportunity not only for Hosting providers offering hosted Private Cloud or Public Cloud Services, but also for Enterprises, to run their own Virtualization platforms or Private Clouds. What is hugely significant is that there is already an end-to-end solution stack […]
Build Your Own Scalable All-Flash Array With SVC
Chris M Evans view on the scalable All-Flash Array and SVC: I’m a big fan of storage virtualisation and SVC has many great features. However scale-out is not one of them. The system may be capable of scaling capacity, but the poor number of logical volumes and extents it supports is severely limiting to many […]
Converged Architectures: it’s the use case, stupid!
Hans de Leenheer writes on his blog: There are two types of converged infrastructure: the one click sale all components in one SKU of which we know VCE vBLOCK, NetApp FlexPod, EMC vSPEX, Hitachi UCP, Dell vStart and HP VirtualSystem or most recently HP Sharks (working title). Technology wise there is hardly any added value […]
Why I love Coho Data
Enrico Signoretti writes on Juku.it: We always talk about “software-defined something” (too much indeed!) but you should take a look at how Coho implements SDN and then I’m sure you’ll come back saying Brillllliant! (yes, brilliant with a capital B and 5 Ls). Coho data masquerades the complexity of scale-out and the limits of the […]
Howto configure a small redundant iSCSI infrastructure for VMware
Luca Dell’Oca writes in his blogpost: I’ve seen often many users asking in forums how to properly configure a network in order to deploy a iSCSI storage, especially in really small environments. So, I created this post in order to explain how I usually configure a system with an HP StorageWorks P2000 G3 iSCSI storage […]
