VMware VSAN… and the missed opportunity

Good post by Enrico Signoretti (thank you)

One of the most interesting (among the few) announcements at VMworld was about VSAN 6.1. The product is quickly maturing and new features are being added version after version (here what’s new). And the product promises to be even better (with erasure coding and dedupe coming up in the next version!).

Virtual SAN beta coming up with dedupe and erasure coding!

Good post by Duncan Epping (thank you)

Something I am personally very excited about is the fact that there is a beta coming up soon for an upcoming release of Virtual SAN. This beta is all about space efficiency and in particular will contain two new great features which I am sure all of you will appreciate testing:

  • Erasure Coding
  • Deduplication

Docker and Storage – Understanding Docker I/O

Good Post by George Crump (thank you)

Designing a Docker Storage Infrastructure

A recent Storage Switzerland report covered the basics of Docker and Storage; what Docker is and how it impacts storage. Container technology and Docker specifically places unique demands on the storage infrastructure that most legacy storage architectures are ill-prepared to handle. The initial concern is developing a storage infrastructure that will support a container based dev/ops environment. The second concern is that these infrastructures will have to support containers in production as the value of something more granular than a virtual machine (VM) is understood.

Is Software-Defined Storage Enough?

Good post by George Crump (thank you)

Initiatives like server virtualization, cloud infrastructure-as-a-service, and real-time analytics are allowing IT to meet today’s ever-increasing business demands. These initiatives are designed to bring agility to the data center, yet they trip and fall when they have to interact with the silo’ed storage infrastructure. Software Defined Storage (SDS) was supposed to be the answer. But for the most part, SDS is really storage software without the reliance on dedicated hardware, and is limited to specific storage containers. Most SDS solutions cannot extend a container across vendors, formats (file, block, object) or protocols. Even hyper-converged systems don’t help. They attempt to solve this problem by moving all enterprise data into a bigger and proprietary container at the server layer.

Throwing hardware at a software problem

Good post by Robin Harris (thank you)

Maybe software will eat the world, but sometimes the physical world gives software indigestion. That fact was evident at the Flash Memory Summit this month.

As mentioned in Flash slaying the latency dragon? several companies were showing remote storage accesses – using NVMe and hopped up networks – in the 1.5 to 2.5µsec range. That’s roughly 500 times better than the ≈1msec averages seen on today’s flash storage.

Samsung announces 16TB SSD

Post by Robin Harris (thank you)

Not just the world’s highest capacity SSD, but the world’s highest capacity drive of any type. The PM1633 uses Samsung’s new 48 layer V-NAND, itself a technical tour-de-force, and represents a new thrust in flash storage beyond performance: capacity.

Diablo Memory 1 Takes Memory Channel Flash To The Next Level

Good post by Stephen Foskett (thank you)

I’ve written about Diablo Technologies in the past, and they’re been part of Tech Field Day and my other events. The company’s products have always blurred the line between storage and memory, placing flash chips on memory modules and leveraging the fast, low-latency memory channel rather than the PCI or SATA/SAS bus. Memory 1 does one better, delivering a true flash DIMM that works in virtually any server.

Why We Don’t Have a Nutanix NX-8150 Review

Good post by Brian Beeler (thank you)

StorageReview has been the largest outlet independently reviewing enterprise IT for many years. For the first time we have to tell the story of how a review in progress came to an end without being published. There have been several instances where we were asked to not post a review by a vendor before, but the reviews always went live. This story is significantly different however, as we encountered a new set of behaviors by Nutanix. The summary is this; Nutanix sent an NX-8150 cluster for review, our testing revealed performance issues, Nutanix made several software updates over six months to improve performance, in June they asked to update our cluster with newer Haswell-based systems, we agreed, Nutanix then backtracked and refused to send the promised replacements.

HP Announces ConvergedSystem 250-HC StoreVirtual

Post by Adam Armstrong (thank you)

Today HP announced a new addition to its ConvergedSystem line, HP ConvergedSystem 250-HC StoreVirtual (CS 250). Like the HP ConvergedSystem 200-HC StoreVirtual, the CS 250 is a hyper-converged appliance that offers highly available virtual server and storage infrastructure. HP claims that CS 250 can be configured in minutes and is almost half the price of its competitors. The CS 250 is designed for virtual desktops and remote offices and offers companies an easy path to the hybrid cloud.

HDS storage is faring better than EMC’s trad arrays, reckons analyst

Post by Chris Mellor (thank you) over at El Reg

EMC is ahead overall with HDS mounting an IoT catch-up

HDS storage revenues are declining, but not as much as EMC’s core storage business. Joe Tucci’s business is doing better in its move to add business outside its trad arrays and HDS is mounting an Internet of Things catch-up, looking to store and analyse the hoped-for IoT data deluge.
