Now that Flash is Everywhere…Where Do We Go from Here?

first_imgFlash has become ubiquitous. It is being deployed on PCIe cards in servers, in all-flash arrays that plug into storage networks, and in hybrid arrays in the form of solid-state drives (SSDs). But where is the best place to deploy flash? Well, that requires the most famous of engineering answers: “It depends.”Application requirements have always driven infrastructure decisions, and flash is no exception. If your application demands the lowest possible latency and highest possible throughput, then flash on a PCIe card in the server, where it is close to your microprocessors could be the answer. PCIe-based flash can deliver hundreds of thousands of IOPS and achieve latencies measured in microseconds. But what if you want to share that flash between servers? In that case, an all-flash array may be the answer. An all-flash array can deliver consistent low latencies in the range of 500 microseconds, provide a rich set of data services like de-duplication and replication, and consolidate workloads from many servers. If it is designed correctly, an all-flash array is built from the ground up to leverage the unique characteristics of flash.Both PCIe and all-flash array solutions tend to optimize around cost per I/O, but what if your application requirements demand greater capacity and are more sensitive to cost per gigabyte? That is where a hybrid array might be the answer. By combining SSDs and spinning disk drives in an array, an application can get an efficient mix of performance and cost if your applications can tolerate the possibility of variable latency.There will be other times when your application will call for running flash everywhere, like an in-memory database attached to a high performance all-flash array and a hybrid array for cost-effective tiering.As time goes by, software will evolve at each layer of the infrastructure stack, and richer feature sets will be delivered.But this is just the beginning.The next step is to abstract the properties of each type of flash deployment—wherever the flash resides in the data center—and create pools of flash defined by performance, cost, capacity and protection requirements. These pools will be managed seamlessly and automatically to provide applications exactly what they need, when they need it, in the most efficient way possible.This is the essence of software-defined flash and it is “where we go from here.”last_img read more

Danish crime show turns lurid procedural trend on its head

first_imgNEW YORK (AP) — A sensational and gruesome murder is approached a little differently in the limited miniseries “The Investigation.” It explores the 2017 murder of Swedish journalist Kim Wall but focuses on the police and her parents, not the brutality of the crime. Writer and director Tobias Lindholm wanted to show almost an inverse of “The Killing,” the Danish series that helped kick off a wave of grim and bleak detective procedurals. Here the camera follows the dogged detectives seeking a logical and scientific cause of death that can convict the accused. Viewers don’t see the bloody crime scene, the murderer or one drop of blood. “The Investigation” premieres on HBO on Feb. 1.last_img read more

Filing claims interference in 2010 Border Patrol death probe

first_imgSAN DIEGO (AP) — Documents filed in an international human rights case say the current head of the U.S. Border Patrol took part in an effort to shield agents following the 2010 death of a man who tried to cross from Mexico into California. The documents made public Thursday involve the death of Anastasio Hernandez Rojas, who was beaten and shocked with a stun gun at the San Ysidro Port of Entry and later died at a hospital. No criminal charges were ever filed. A document submitted to the Inter-American Commission on Human Rights contends that Border Patrol chief Rodney Scott and others obstructed criminal investigations.last_img read more
