Network, your next big storage problem!

data

Good post by Enrico Signoretti (thank you)

A few days ago I had an interesting chat with Andy Warfield at Coho Data and the topic of Network/Storage relationship came up several times. (Quick disclaimer: I’m currently doing some work for Coho)

In a couple of my latest articles (here and here) I talked about why many large IT organizations prefer PODs to other topologies for their datacenters but I totally forgot to talk about networking (I also have to admit that networking is not my field at all). So, this article could be the right follow-up for those posts.

XPoint put under the analyst microscope

Good post by Chris Mellor (thank you) over at El Reg

80-page report gets under the skin of memristor-slaying 3D XPoint tech

Semiconductor market researcher Jim Handy of Objective Analysis has produced an 80-page report looking into what XPoint memory is, how it could be used and what its prospects are.

XPoint memory was unveiled by Micron and Intel in July to general amazement. The pair claimed it was 1,000 times faster than NAND, ten times denser and also less costly than DRAM, and would form a new memory hierarchy between DRAM and flash.

D-round VC ReRAM cash comes crashing down on Crossbar

Good post by Chris Mellor (thank you)

Close, so close to getting its ReRAM afloat before Intel and Micron barge in

Resistive RAM memory tech startup Crossbar has snagged $35m in D-round funding to push the commercial ramp of its non-volatile memory (NVM) technology.

Hong Kong-based Tyche Partners, China-based Oriza Holdings and unknown and possibly Hong Kong-based VC Cheerful Link joined all of Crossbar’s existing investors in the round, bringing total investment to $85m to date.

NAND, DRAM, SAS/SCSI and SATA/AHCI: Not Dead, Yet

Post by Greg Schulz (thank you)

Manufacturers are coming out with new non-volatile memory (NVM) media like 3D XPoint. Does that mean that DRAM and other NVM media such as NAND flash are now dead?

Do new NVM storage access protocols such as NVM Express (NVMe) mean SCSI/SAS and AHCI/SATA are now dead?

My simple answer is no, they all have bright futures.

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”.

When Solid State Drives are not that solid

Post by Adam Surak (thank you)

It looked just like another page in the middle of the night. One of the servers of our search API stopped processing the indexing jobs for an unknown reason. Since we build systems in Algolia for high availability and resiliency, nothing bad was happening. The new API calls were correctly redirected to the rest of the healthy machines in the cluster and the only impact on the service was one woken-up engineer. It was time to find out what was going on.

Faster Ethernet Gets Weird

Good post by Stephen Foskett (thank you)

Once upon a time there was Ethernet. Every half decade or so, the industry got together and worked out a faster version. Sometimes they didn’t totally agree, but a standard emerged at 10x the speed of the previous version. Throw all that out the window: Faster Ethernet is coming, and it’s going to be weird!

SSD Endurance. What does it mean to you?

Good post by Andrey Kudryavtsev (thank you)

I continuously think about the endurance aspect of our products, how SSD users understand it and use it for its positive benefits. Sadly, endurance is often underestimated and sometimes overestimated. I see customers buying High Endurance products for the benefit of protection, without understanding the real requirements of the application. Now that piece of night thoughts goes to my blog.

Musing: Could We Replace Ethernet With PCIe?

Good post by Stephen Foskett (thank you)

Greg “EtherealMind” Ferro recently “mused” that it might be a good idea to replace PCI Express (PCIe) inside servers or rack-scale infrastructure with Ethernet. But this seems to be the exact opposite of the direction the industry is headed. Rather than replacing PCIe with Ethernet, companies like Intel seem set on replacing short-range Ethernet (in rack-scale systems) with PCIe!

HP Discover Review: The Machine

Good post by Chris M Evans (thank you)

One of the regular features of HP Discover over recent years has been the blogger “Coffee Talks”, informal sessions with various teams from within HP, covering Big Data, Storage, Networking and so on.  There is even a Coffee Talk on printers that was apparently quite enlightening, although I didn’t attend that one.  Each year (or twice yearly for those who make it), we have a presentation from HP Labs, the section of the company focused on new innovations.  One new technology emerging from the Labs is something HP refer to as “The Machine”.
