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.

3D TLC NAND flash, your new SATA disk

2015

Good post by Luca Dell’Oca (thank you)

In 2014, in a presentation I’ve done, I’ve said to people that in 2-3 years new and cheaper flash memory would have become the standard solution for general purpose disk storage, thanks to a price per GB comparable with spinning disk. Seems that I was right after all.

What is NVMe? And what does it mean for PCIe-SSD?

Good post by George Crump (thank you)

There are two constants in data center storage; the need for greater performance and the need for greater capacity. Flash based storage devices have become the go-to option to address the first challenge. But application owners and users quickly move from an initial euphoria with flash performance to demanding more. Since the flash NAND is essentially the constant in the equation, the surrounding infrastructure has to evolve to extract optimal performance from the technology. But achieving maximum performance often leads to proprietary architectures and designs. NVMe (Non Volatile Memory) is a new industry standard that enables data centers to realize full flash potential without compatibility headaches.

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.

Diablo Memory 1 Takes Memory Channel Flash To The Next Level

Good post by Stephen Foskett (thank you)

I’ve written about Diablo Technologies in the past, and they’re been part of Tech Field Day and my other events. The company’s products have always blurred the line between storage and memory, placing flash chips on memory modules and leveraging the fast, low-latency memory channel rather than the PCI or SATA/SAS bus. Memory 1 does one better, delivering a true flash DIMM that works in virtually any server.

How to safely use 8TB Drives in the Enterprise

Good post by George Crump (thank you)

After a few year hiatus higher capacity hard drives are coming to market. We expect 8TB drives to be readily available before the end of the year with 10TB drives soon to follow. And at the rate that capacity demands are increasing those drives can’t get here soon enough. But, these new extremely high-capacity disk drives are being met with some trepidation. There are concerns about performance, reliability and serviceability. Can modern storage systems build enough safeguards around these products for the enterprise data center to count on them?

Why Virtual Volumes?

Post by Andrew Sullivan (thank you)

How many times in the last 3-4 years have you heard “Virtual Volumes”, “VVols”, “Storage Policy Based Management”, or any of the other terms associated with VMware’s newest software-defined storage technology?  I first heard about VVols in 2011, when I was still a customer, and the concept of no longer managing my virtual machine datastores, but rather simply consuming storage as needed with features applied as requested, was fascinating and exciting to me.

Using RAID-5 Means the Sky is Falling!

Good post by Olin Coles (thank you)

Why disk URE rate does not guarantee rebuild failure.

Today’s appointment brought me out to a small but reliable business, where I’m finishing the hard drive upgrades for their cold storage backup system. It was an early morning drive into the city, with enough ice on the roads to contribute towards the more than 30,000 fatality accidents that occur each year1. The backup appliance I’m servicing has received 6TB desktop hard disks to replace an old set with a fraction of the capacity, so rebuilding the array has taken considerable time.
