Down the rabbit hole with Kubernetes Storage

Kubernetes is on fire. Last week VMware® released the State of Kubernetes 2020 report which surveyed companies with 1,000 employees and above. Results were not surprising as the adoptions of this nascent technology are booming. But persistent storage remained the nagging concern for the Kubernetes serving the infrastructure resources to applications instances running in the containers of a pod in a cluster.

The standardization of storage resources have settled with CSI (Container Storage Interface). Storage vendors have almost, kind of, sort of agreed that the API objects such as PersistentVolumes, PersistentVolumeClaims, StorageClasses, along with the parameters would be the way to request the storage resources from the Pre-provisioned Volumes via the CSI driver plug-in. There are already more than 50 vendor specific CSI drivers in Github.

The CSI plug-in method is the only way for Kubernetes to scale and keep its dynamic, loadable storage resource integration with external 3rd party vendors, all clamouring to grab a piece of this burgeoning demands both in the cloud and in the enterprise.

A Dialogue between 2 Drives

I was talking to an end user who was slowly getting exposed to the cloud amid this Covid-19 pandemic. The whole work from home thingy was not new to him, but the scale of the practice suddenly escalated when more than 80 of his staff have to work from wherever they were stuck at during the past 6 weeks. Initially all of his staff had to alternate their folders and files access because their Sonicwall® Global Client license and SSL VPN Clients were inadequate. Even after their upgrade of the licenses, the performance of getting the folders and files through the Z: drive was poor and the network was chocked up. I told them that regardless, the SMB protocol of the NAS shared folders was chatty and generated a lot of network traffic on the VPN, along with the inadequacies of running this over the wide area Internet network. Staff productivity obviously nosedived.

We are now exploring putting their work in the cloud but maintaining a consistent synchronized set of folders and files at all times. Wasabi® Cloud has emerged the most attractive price/GB/month and no egress or API requests fees.

Combining 2 shared drives into one

NAS Drive talking to Cloud Drive like 2 buddies

Now here is a story of 2 Drives

The end user is not an IT savvy user. They were unfamiliar with Cloud Storage other than the free personal ones like Google Drive, or Dropbox. They have more than 200TB and I have introduced to them Wasabi® Cloud. They were very familiar with their Z:, their NAS Drive. I introduced to them the Cloud Drive.

NAS: Hey, how’s it going?

Cloud: Not bad. My boss and your boss are talking about bringing me and Wasabi® Cloud to join your gang. Hope you are OK with that.

The Falcon to soar again

One of the historical feats which had me mesmerized for a long time was the 14-year journey China’s imperial treasures took to escape the Japanese invasion in the early 1930s, sandwiched between rebellions and civil wars in China. More than 20,000 pieces of the imperial treasures took a perilous journey to the west and back again. Divided into 3 routes over a decade and four years, not a single piece of treasure was broken or lost. All in the name of preservation.

Today, that 20,000 over pieces live in perpetuity in 2 palaces – Beijing Palace Museum in China and National Palace Museum Taipei in Taiwan

Digital data preservation

Digital data preservation is on another end of the data lifecycle spectrum. More often than not, it is not the part that many pay attention to. In the past 2 decades, digital data has grown so much that it is now paramount to keep the data forever. Mind you, this is not the data hoarding kind but to preserve the knowledge and wisdom which is in the digital content of the data.

[ Note: If you are interested to know more about Data -> Information -> Knowledge -> Wisdom, check out my 2015 article on LinkedIn ]

SNIA (Storage Networking Industry Association) conducted 2 surveys – one in 2007 and another in 2017 – called the 100 Year Archive, and found that the requirement for preserving digital data has grown multiple folds over the 10 years. In the end, the final goal is to ensure that the perpetual digital contents are

  • Accessible
  • Undamaged
  • Usable

All at an affordable cost. Therefore, SNIA has the vision that the digital content must transcend beyond the storage medium, the storage system and the technology that holds it.

The Falcon reemerges

A few weeks ago, I had the privilege to speak with Falconstor® Software‘s David Morris (VP of Global Product Strategy & Marketing) and Mark Delsman (CTO). It was my first engagement with Falconstor® in almost 9 years! I wrote a piece of Falconstor® in my blog in 2011.

StorageGRID gets gritty

NetApp® presented StorageGRID® Webscale (SGWS) at Storage Field Day 19 last month. It was timely when the general purpose object storage market, in my humble opinion, was getting disillusioned and almost about to deprive itself of the value of what it was supposed to be.

Cheap and deep“, “Race to Zero” were some of the less storied calls I have come across when discussing about object storage, and it was really de-valuing the merits of object storage as vendors touted their superficial glory of being in the IDC Marketscape for Object-based Storage 2019.

Almost every single conversation I had in the past 3 years was either explaining what object storage is or “That is cheap storage right?

Paradigm shift of Dev to Storage Ops

A funny photo (below) came up on my Facebook feed a couple of weeks back. In an honest way, it depicted how a developer would think (or the lack of thinking) about the storage infrastructure designs and models for the applications and workloads. This also reminded me of how DBAs used to diss storage engineers. “I don’t care about storage, as long as it is RAID 10“. That was aeons ago 😉

The world of developers and the world of infrastructure people are vastly different. Since cloud computing birthed, both worlds have collided and programmable infrastructure-as-code (IAC) have become part and parcel of cloud native applications. Of course, there is no denying that there is friction.

Welcome to DevOps!

The Kubernetes factor

Containerized applications are quickly defining the cloud native applications landscape. The container orchestration machinery has one dominant engine – Kubernetes.

In the world of software development and delivery, DevOps has taken a liking to containers. Containers make it easier to host and manage life-cycle of web applications inside the portable environment. It packages up application code other dependencies into building blocks to deliver consistency, efficiency, and productivity. To scale to a multi-applications, multi-cloud with th0usands and even tens of thousands of microservices in containers, the Kubernetes factor comes into play. Kubernetes handles tasks like auto-scaling, rolling deployment, computer resource, volume storage and much, much more, and it is designed to run on bare metal, in the data center, public cloud or even a hybrid cloud.

Rebooting Infrascale

Infrascale™ was relatively unknown for the Storage Field Day 19 delegates when they presented a few weeks ago in San Jose. Between 2015-2017, they have received several awards and accolades, including being in the Leaders quadrant for the 2017 Gartner Magic Quadrant for DR-as-a-Service.

I have known of Infrascale since 2016 as the BC and DR landscape was taking off back then, gravitating towards the cloud as a secondary platform for recovery.

Tiger Bridge extending NTFS to the cloud

The NTFS File System has been around for more than 3 decades. It has been the most important piece of the Microsoft Windows universe, although Microsoft is already replacing it with ReFS (Resilient File System) since Windows Server 2012. Despite best efforts from Microsoft, issues with ReFS remain and thus, NTFS is still the most reliable and go-to file system in Windows.

First reaction to Tiger Technology

When Tiger Technology was first announced as a sponsor to Storage Field Day 19, I was excited of the company with such a cool name. Soon after, I realized that I have encountered the name before in the media and entertainment space.

Hadoop is truly dead – LOTR version

This blog was not intended because it was not in my plans to write it. But a string of events happened in the Storage Field Day 19 week and I have the fodder to share my thoughts. Hadoop is indeed dead.

Warning: There are Lord of the Rings references in this blog. You might want to do some research. 😉

Storage metrics never happened

The fellowship of Arjan Timmerman, Keiran Shelden, Brian Gold (Pure Storage) and myself started at the office of Pure Storage in downtown Mountain View, much like Frodo Baggins, Samwise Gamgee, Peregrine Took and Meriadoc Brandybuck forging their journey vows at Rivendell. The podcast was supposed to be on the topic of storage metrics but was unanimously swung to talk about Hadoop under the stewardship of Mr. Stephen Foskett, our host of Tech Field Day. I saw Stephen as Elrond Half-elven, the Lord of Rivendell, moderating the podcast as he would have in the plans of decimating the One Ring in Mount Doom.

So there we were talking about Hadoop, or maybe Sauron, or both.

The photo of the Oliphaunt below seemed apt to describe the industry attacks on Hadoop.
