MRAM technology likely choice as post-flash solid-state storage
This article is part of the May 2013 Vol. 12 No. 3 issue of Storage magazine
NAND flash-based storage could be replaced by newer forms of non-volatile memory like MRAM technology. Find out why MRAM's density, cost and form factor could make flash obsolete. Flash storage is everywhere these days. It's hard to have a discussion about IT infrastructure without someone talking about how flash storage can be leveraged to make server and storage architectures faster. It's not necessarily cheaper, although a large increase in workload hosting density can provide cost justification. But it will certainly deliver higher performance at key points in the I/O stack in terms of outright latency; and with clever approaches to auto-tiering, write journaling and caching, higher throughputs are within easy reach. But flash as a non-volatile random-access memory (nvRAM) technology has its problems. For one, it wears out. The most common type of flash is based on NAND transistors like static RAM (SRAM), but has an internal "insulation" layer that can hold an electric charge without external power. This is what makes it ...

Virtual server storage operations can have a profound effect on the storage network. Here are 10 ways to help ensure that your storage yields its best I/O for the VMs it supports.
A data backup appliance combines software and hardware in a single box, configured and ready to go. Once considered just an SMB option, these products are ready for the enterprise.
IT data storage is always a struggle, but storage managers should have a little more money in 2013 to spend on techs that can help ease the crunch of growing capacity demands.

Many storage shops are fighting a losing battle when it comes to data storage and backup protection, with too much data and not enough time. Maybe it's time to rethink the process.
Storage virtualization and other storage "uber-controllers" are a step toward better storage infrastructure management, but it's still not an integrated process.
Object technology has received a lot of attention lately, so there should be plenty of use cases for it. But object storage might be the answer to a problem not yet discovered.
NAND flash-based storage is becoming a common alternative, but NAND flash could soon be replaced by newer forms of non-volatile memory like MRAM technology.
