3D Xpoint memory: Faster-than-flash storage unveiled

Good post by Leo Kelion (thank you)

A new kind of memory technology is going into production, which is up to 1,000 times faster than the Nand flash storage used in memory cards and computers’ solid state drives (SSDs). The innovation is called 3D XPoint, and is the invention of Intel and Micron. The two US companies predict a wide range of benefits, from speeding up scientific research to making more elaborate video games. One expert described it as a “huge step forward”.

Hadoop Storage: DAS vs. Shared

Post by George Crump (thank you)

Hadoop is a software solution that was developed to solve the challenge of doing a very rapid analysis of vast, often disparate data sets. Also known as big data, the results of these analytics, especially when produced quickly, can significantly improve an organization’s ability to solve problems, create new products and to cure diseases. One of the key tenets of Hadoop is to bring the compute to the storage instead of the storage to the compute. The fundamental belief is that the network in-between compute and storage is too slow, impacting time to results.

Cisco Confirms It Is Ending Its Invicta Storage Appliance

Good post by Adam Armstrong (thank you)

According to both The Register and CRN, Cisco has confirmed that will cease its Invicta Storage Array line. Cisco first acquired the Invicta All-Flash array when it purchased Whiptail in 2013 for $415 million. Within a year Cisco halted shipments from apparent customer complaints. After two years of issues, Cisco will no longer develop the Invicta Appliance and its Scaling Systems products.

Native PCI Express Back-end Interconnect in FlashArray//m

Good post by Roland Dreier (thank you)

Many storage users are familiar with ALUA, or Asymmetric Logical Unit Access. This describes storage where some paths don’t work at all or give lower performance, because of standby controllers, volumes associated with a controller, or other architectural reasons.  The Pure Storage FlashArray provides symmetric access to storage — any IO to any volume on any port always gets the same performance.

Software-Defined Storage in OpenStack

Good post by Rawlinson Rivera (thank you)

t’s time expand and showcase the strength of software-defined storage at the upcoming OpenStack Summit. Take a look at the abstract of the session I’m scheduled to participate as a speaker and lets’ get that bad boy vote in and into the schedule.

Getting the Bang for your Buck with Software-Defined Storage in OpenStack

OpenStack has become the standard infrastructure consumption layer for a variety of applications. These applications have different storage requirements and being able to provide a storage solution that matches these requirements is critical to ensure the adoption of OpenStack as the cloud platform of choice across a wide array of applications.

Microsegmentation: How VMware Addresses the Container Security Issue

Post by Scott M. Fulton III (thank you)

Easily the most astonishing result from ClusterHQ’s most recent State of Container Usage survey [PDF] was that nearly three-fourths of 229 IT professional respondents said their data centers are running containers in a hypervisor-virtualized environment — that is to say, a container environment inside the safety of a separate virtualization layer. That figure was bolstered by about 61 percent of respondents saying that security remained a barrier to their data centers’ adoption of containers in production.

Object storage: why, when, where… and but.

Good post by Enrico Signoretti (thank you)

In one of my latest posts I wrote about private object storage not being for everyone… especially if you don’t have the size that makes it viable… But, on the other hand we are all piling up boatloads of data and users need to access it from many different locations, applications and devices at anytime.

Flash Storage Prices Have a Long Way to Fall. Here’s Why.

Good post by Paul Rubens (thank you)

High-performance flash-based storage is increasingly insinuating itself into enterprise infrastructure. It’s showing up in everything from server caches and directly attached storage to hybrid arrays and fully solid state storage appliances.

But corporate storage requirements are exploding, meaning enterprises will need far more storage capacity — both flash and spinning hard disk storage — in the future.

The Guide to Selecting Flash for Virtual Environments

Good post by George Crump (thank you)

High performance flash based storage has dramatically improved the storage infrastructure’s ability to respond to the demands of servers and the applications that count on it. Nowhere does this improvement have more potential than in the virtualized server environment. The performance benefits of flash are so great that it can be deployed indiscriminately and still performance gains can be seen. But doing so may not allow the environment to take full advantage of flash performance. It may also be a much more expensive deployment model and put data at risk. Modern data centers need to understand which forms of flash and which deployment models will show the greatest return on investment while not risking any data.

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.
