How to Store Data Using Single Atoms

How to Store Data Using Single Atoms

Researchers at Delft University of Technology build a prototype storage device able to store data using single atoms-- providing theoretical capacity of 500TB per square inch.

Such capacity is 500 times more dense than the highest capacity HDDs available to date and, as lead scientist Sander Otte puts it, “would allow all books ever created by humans to be written on a single post stamp.”

The atomic storage technology makes use of a scanning tunneling microscope (STM), a technique allowing the moving of individual atoms. The prototype consists of a flat copper bed covered with around 60000 chlorine atoms, with 8000 empty spaces left around them. The STM was used to arrange the atoms in a grid with gaps representing data, bringing about a means of storage that works more or less like a sliding puzzle.

Datrium Storage Gets Insane Mode

Datrium Storage Gets Insane Mode

The Datrium DVX storage system gets a software update the company calls "Insane Mode"-- one promising a 2-fold increase in server application performance without need for a controller change.

The increase brings about 100000 IOPS per host and 3 million IOPS per DVX system.

DVX is based around private cloud computing elasticity. The system powers storage performance through a small amount of compute from each virtualised server, allowing it to get faster with every server. Insane Mode increases storage IO on a server from 20% to 40%, bringing about a doubling in storage performance.

Operators can boost DVX storage performance for VMs in 2 ways-- one can either vMotion the workload to a server with more resource capacity (if the host lacks CPU or flash headroom) or turn on Insane Mode in the case of unused local CPU headroom.

Dell Brings Storage Together With SCOS7

Dell Brings Storage Together With SCOS7

Dell provides admins with a single management interface and means to replicate data between both Storage Center and EqualLogic PS storage arrays with a pair of free upgrades-- Storage Center OS 7 and PS 9.0.

The Dell "SC" line denotes storage products derived from Compellent, while "PS" refers to technologies aquired from EqualLogic.

SCOS 7 targets all-flash and hybrid flash arrays, and “aggressively promotes the adoption of flash, by bringing lower acquisition costs across flash and hybrid arrays and provides investment protection for Dell PS Series customers as they explore future-ready technologies." It also promises data deduplication and tools ensuring the right quality of application service from SC arrays.

The result, the company claims, brings capacity savings of up to 10:1 with a typical gain of 4:1 or 3:1, as well as cost savings on SC arrays of both flash and HDD varieties.

Synology Updates DiskStation NAS Offering

Synology announces a pair of DiskStation NAS products-- the DS916+ 4-bay scalable NAS aimed at professionals and small businesses, and the 1-bay DS116 ideal for home users and small workgroups.

A successor to the DS415+, the DS916+ supports up to 9 drives through compatibility with the DX513 expansion unit. It carries an Intel Pentium N3710 quad-core CPU complete with AES-NI hardware encryption engine, and either 2 or 8GB RAM, while speeds reaches a link aggregate average 225.91MB/s read and 221.04MB/s write (or 225.83MB/s and 209.35MB/s encrypted read and write).

In professional-friendly features the DS916+ supports real-time H.264 single-channel 4K/UHD or triple channel HD video transcoding, while power consumption reaches up to 30W when accessing drives and as little as 13W in HDD hibernation mode. Also included is DiskStation Manager OS software.

IBM Refreshes FlashSystem for Cloud

IBM Refreshes FlashSystem for Cloud

IBM announces 3 additions to the FlashSystem all-flash array portfolio-- the A9000, A9000R and DS8888, all promising a minimum latency of 250μs (microsecond) for the rapid access of data in cloud-based workloads.

Inside the arrays are MicroLatency modules, proprietary flash drives Big Blue says are superior to alternative technologies by being able to transfer data within the flash array via hardware instead of (slower) software.

The A9000 is a full-configured 8U system featuring 3 controllers designed for cloud, VDI and VMware workloads, while the A9000R is a racked grid-design system for mixed-use and cloud workloads. Both offer data reduction features such as pattern removal, deduplication and real-time compression, a REST API, multi-tenancy capabilities, noisy-neighbour removal capabilities and integration with Microsoft, VMware, OpenStack and IBM SoftLayer environments.
