Pure Storage’s coming high-end array: We have the details

Good post by Chris Mellor (thank you) over at El Reg

We can tell you a few more juicy details about Pure’s coming high-end array, and we’re deducing that SolidFire has a product capacity refresh coming.

What we knew was that the new range-topper would boast up to 1.5PB usable capacity using 4 and 8TB 3D NAND modules (SSDs). It would have always-on QoS, support thousands of virtual machines and be priced at less than $1GB/usable capacity.

vSphere tackles the Hyperconverged Infrastructure World: VMware VSAN 6.2

Good Post by W. Curtis Preston (thank you)

VMware is releasing VSAN 6.2, the third major release of VSAN since its introduction in August of 2014. (Like other VMware companion products, the release number is tied to the vSphere release number it is associated with.) This release gives vSphere most if not all of the major features found in other hyperconverged infrastructure products.

More data services in VSAN 6.2

Good Post by Andrea Mauro (thank you)

As announced some months ago, the new Virtual SAN (VSAN 6.2) will add new data services making this solution more rich that before. Version 6.1 was announced during the last VMworld editions with some interesting features, including a ROBO scenario.

But was still limited in data service: better snapshot technologies, better VMFS, but still some limits and no deduplication, no compression, no erasure coding at all.

Traffic Isolation Zoning – The mistake of FOS

Good post by Erwin van Londen (thank you)

If there is one thing I would consider “the” blunder of FOS engineering it has to be Traffic Isolation zoning. I mean, creating such an administrative nightmare with obscure directions causing confusion and nasty pitfalls when one thing goes wrong is in many occasions a recipe for disaster.

The Storage Requirements for 100% Virtualization

Post by George Crump (thank you)

After a rapid move from test to production, virtualization of existing servers in many companies seems to slow down. While it is true that most data centers have adopted a virtualize first philosophy, getting those older, mission critical workloads virtualized seems to be a thorny issue. These applications are often at the heart of an organization’s revenue or customer interaction and tend to be unpredictable in the resources they require. This is especially true when it comes to storage and networking.

Where VSAN doesn’t shine: Sources explain EMC’s ScaleIO purpose

Good post by Chris Mellor (thank you)

EMC introduced its scale-out ScaleIO Node virtual SAN a couple of weeks ago, with hybrid flash-disk and all-flash server chassises. It overlaps as a product with EMC-owned VMware’s VSAN, and therefore EMC’s EVO:RAIL implementation of that, and also competes with scale-out all-flash arrays.

Discussions with sources have clarified EMC’s thinking on the topic, and showed that the overlap is less than originally thought.

OCZ’s NVMe SSDs provide Lower Latency and Faster, more Consistent Performance

Post by George Crump (thank you)

When non-volatile flash memory-based solid-state drives (SSDs) were introduced, the protocol support included SAS/SATA. These interfaces were designed for hard disk drives (HDDs) and had more latency than was ideal for flash, but it made for easier integration of SSDs into enterprise storage systems and servers since the existing infrastructure was built around HDDs. SSDs were forced into the mold of HDD storage including the physical interface, host control interface and storage logic. Though PCIe flash drives became a step in the right direction, they lacked the ease of implementation that SAS/SATA SSDs have and do not fully expose the performance that NAND flash can offer.

The Benefits of a Cloud Integrated Hyper-converged Architecture

Post by George Crump (thank you)

Hyper-converged architectures (HCA) consolidate compute, storage and networking onto a single server and then through software, aggregate these servers, creating a shared pool of resources. These resources can then be allocated to virtual machines (VMs) based on their performance and capacity demands. The goal is to simplify the purchasing, implementation and operation of the data center by consolidating or converging it. The logical next step for HCA is to extend its capabilities to the cloud allowing data centers of all sizes to achieve greater flexibility and resilience from disaster.

Next-generation storage for the software-defined datacenter

Post by Siddhartha Roy and Paul Luber (thank you)

Storage is a foundational component of the datacenter fabric and is an intrinsic part of Microsoft’s software-defined datacenter solution.  Our storage investments are centered on bringing value to customers in terms of increasing cloud scale, availability, performance, and reliability, while lowering acquisition and operational costs – with Windows Server, and now also with Microsoft Azure Stack.
