Making All-Flash 3D TLC SSD Arrays Enterprise Ready

3d-nano-ssd-rcm992x0

Good post by George Crump (thank you)

All-Flash Array Vendors are now releasing systems with 3D TLC SSDs. They claim that they have reached price parity, without data efficiency, to mainstream data center hard disk arrays. 3D TLC NAND does bring the price per GB of flash storage down considerably, but it does carry the risk of device failure and data loss. Understanding how a vendor mitigates that risk is critical to vendor selection.

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.

Amazon, Azure and Google in race to the bottom … of cloud storage pricing

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

Storage 2016 A period of quiet, rest and reflection is what the storage industry needs after a frankly hectic and very eventful 2015.

It won’t get it. The opposing forces of simplicity and complexity, access speed versus capacity, server versus array, on premises versus cloud, and tuned hardware and software versus software-defined are still in deep conflict. And don’t forget the containerisation issues in the background.

There is also a growing generalised attack on storage data access latency, just to add something else into the mix.

VVOLs and VMware

Post by Christine Taylor (thank you)

The definition of VVOLs is simple but the effect is ground-breaking. Here is the simple definition part: Virtual Volumes (VVOL) is an out-of-band communication protocol between array-based storage services and vSphere 6.

And here is the ground-breaking part: VVOLs enables a VM to communicate its data management requirements directly to the storage array. The idea is to automate and optimize storage resources at the VM level instead of placing data services at the LUN (block storage) or the file share (NAS) level.

Dispelling Myths about IOPs

Good post by Hu Yoshida (thank you)

Since the SPC numbers for the G1000 came in at 2 million IOPs and blew away every other all flash array vendor, there have been a number of posts in the blog sphere discussing the relevance of IOPs as a measure of performance. Lets look at some of the myths about IOPs.

Data Protection: All Starts with an Architecture

Post by Edward Haletky (thank you)

At The Virtualization Practice, we have systems running in the cloud as well as on-premises. We run a 100% virtualized environment, with plenty of data protection, backup, and recovery options. These are all stitched together using one architecture: an architecture developed through painful personal experiences. We just had an interesting failure—nothing catastrophic, but it could have been, without the proper mindset and architecture around data protection. Data protection these days does not just mean backup and recovery, but also prevention and redundancy.

Understanding RAID Performance at Various Levels

Excellent post by Scott Alan Miller (thank you)

Choosing a RAID level is an exercise in balancing many factors including cost, reliability, capacity, and of course, performance. RAID performance can be difficult to understand, especially as different RAID levels use different techniques and behave rather differently from each other in some cases. In this article, I want to explore the common RAID levels of RAID 0, 5, 6, and 10 to see how performance differs between them.

Sorry Nimble Storage – I Don’t Believe You!

Good post by Nigel Poulton (thank you)

So a few weeks ago I was at Nimble Storage HQ for a briefing with the Storage Field Day crew. Nice site, nice breakfast, and thanks for contributing towards my travel and hotel costs (that’s the disclaimer out of the way).

The Claim!

Anyway, as part of the presentation, Rod Bagg (VP of Customer Support) made the claim that ~60% of Nimble storage arrays get upgraded during business prime time hours.
