Upcoming articles for Computer Weekly: storage

For Computer Weekly I am writing two further articles on storage technology. One on and one on Flash storage and RAID, the other on hyper-converged use cases.

Flash storage and RAID

For this article, we will look at how RAID technology works with Flash storage. Why does RAID still matter with Flash, and how will it operate with new storage technologies that could eventually replace Flash?

We will include:

  • Which RAID level is best for flash performance?
  • What benefits and drawbacks are there with parity based RAID in flash?
  • What are the benefits and drawbacks of mirrored RAID levels with flash storage?
  • What proprietary or branded RAID levels do the main vendors of flash storage offer? How do these translate into the commonly understood RAID levels?
  • What will supersede RAID as a means of drive/array data protection? For example erasure coding?

The deadline for submission of material is 1700, Wednesday 18th November. I can quote analysts and consultants; although I can’t quote vendors I welcome white papers or technical papers and case studies, as well as relevant product information.

Hyper-converged storage use cases

This article will look at five current use cases for hyper-converged storage.

The article will look at how hyper converged infrastructure works and where storage sits within that.

I am open to suggestions for the key use cases but the feature is likely to include:

  • Virtual machines and virtual desktops
  • Backup and recovery using HCI
  • High-performance, data rich applications such as AI and advanced analytics
  • Containers
  • Possible use of HCI by smaller businesses.

The deadline for submission of material is 1700, Monday 23rd November. The same quotation rules apply.

Upcoming article: Flash storage tiers

For Computer Weekly, I am writing a short piece looking at the various tiers of solid-state storage.

What is on the market, how does each technology’s performance differ, and what are their applications? Why do businesses use tiered storage, and where does each solid state technology fit into tiering?

I will cover these storage types:

  • Optane/3D Xpoint/Z-NAND
  • NVMe
  • TLC Flash
  • QLC Flash

If you have market research or other information to share on these, the deadline to contact me — as ever by email — is 1700hrs, Friday 14th February.
