Storage Elephant Compute Birds

Data movement is expensive. Not just costs, but also latency and resources as well. Thus there were many narratives to move compute closer to where the data is stored because moving compute is definitely more economical than moving data. I borrowed the analogy of the 2 animals from some old NetApp® slides which depicted storage as the elephant, and compute as birds. It was the perfect analogy, because the storage is heavy and compute is light.

“Close up of a white Great Egret perching on top of an African Elephant aa Amboseli national park, Kenya”

Before the animals representation came about I used to use the term “Data locality, Data Mobility“, because of past work on storage technology in the Oil & Gas subsurface data management pipeline.

Take stock of your data movement

I had recent conversations with an end user who has been paying a lot of dollars keeping their “backup” and “archive” in AWS Glacier. The S3 storage is cheap enough to hold several petabytes of data for years, because the IT folks said that the data in AWS Glacier are for “backup” and “archive”. I put both words in quotes because they were termed as “backup” and “archive” because of their enterprise practice. However, the face of their business is changing. They are in manufacturing, oil and gas downstream, and the definitions of “backup” and “archive” data has changed.

For one, there is a strong demand for reusing the past data for various reasons and these datasets have to be recalled from their cloud storage. Secondly, their data movement activities still mimicked what they did in the past during their enterprise storage days. It was a classic lift-and-shift when they moved to the cloud, and not taking stock of  their data movements and the operations they ran on these datasets. Still ongoing, their monthly AWS cost a bomb.

I am not cybersecurity guy at all. Cybersecurity, to me, is a hodgepodge of many things. It is complex and it is confusing. But to every organization that has to deal with cloud SaaS (software-as-a-service) applications, mobile devices, work from home, and the proliferation of network connections from everywhere to the edge and back, strong cybersecurity without the burden of sluggish performance and without the complexity of stitching the cybersecurity point solutions would be a god send.

About 3 1/2 years ago, when I was an independent consultant, I was asked by a friend to help him (I was also looking for a gig) sell a product. It was Aryaka Networks, an SD-WAN solution. It was new to me, although I had some MPLS (multi protocol label switching) knowledge from some point in my career. But the experience with Aryaka at the people level was not too encouraging, with several people I was dealing with, switching positions or leaving Aryaka, including their CEO at the time, John Peters. After about 4 months or so, my friend lost confidence and decided to switch to Cato Networks.

Cato Networks opened up my eyes to what I believe cybersecurity should be. Simple, performant, and with many of the previous point requirements like firewall, VPN, zero trust networks, identity management, intrusion prevention, application gateways, threat detection and response, remote access, WAN acceleration and several more, all beautifully crafted into a single cloud-based service. There was an enlightenment moment for a greenhorn like me as I learned more about the Cato solution. That singularity of distributed global networking and cybersecurity blew me away.

Control your Files. Control your Sovereignty.

Data residency, data sovereignty, data localization – the trio of data compliance and governance – have been on my mind a lot lately. I am seeing a disturbing trend. “Splinternet” has taken a hurried and hastened pace. We are now seeing many countries drawing up digital boundaries in the name of data privacy and data protection with sovereign laws and regulations. Besides, these digital demarcation along the lines with data definitions, digital “colonization” is a strong undercurrent as developing countries are accepting larger and more powerful foreign powers into their playpen.

Public cloud services transcend national borders. The breakneck speed in the adoption of public cloud services is causing anxieties and concerns with conservative governments everywhere. On the flip side of the coin, commerce has certainly flourished and bloomed as global wide collaborations bring new opportunities, new markets – all for capitalism and growth.

[ Note: While we are on this debacle, the voices of decentralization are getting louder as well, but that is a topic for another day ]

Where are your data files now?

Right time for Andrew. The Filesystem that is.

I couldn’t hold my excitement when I discovered Auristor® early last week. I stumbled upon this Computerweekly article “Want to side step Public Cloud? Auristor® offers global file storage.” Given the many news not exactly praising the public cloud storage vendors nowadays, the article’s title caught my attention. Immediately Andrew File System (AFS) was there. I was perplexed at first because I have never seen or heard a commercial version of AFS before. This news gave me goosebumps.

For the curious, I am sure many will ask who is this Andrew anyway? What is my relationship with this Andrew?

One time with Andrew

A bit of my history. I recalled quite vividly helping Intel in Penang, Malaysia to implement their globally distributed file caching mechanism with the NetApp® filer’s NFS. It was probably 2001 and I believed Intel wanted to share their engineering computing (EC) files between their US facilities and Intel Penang Design Center (PDC). As I worked along with the Intel folks, I found out that this distributed file caching technology was called Andrew File System (AFS).

Although I couldn’t really recalled how the project went, I remembered it being a bed of bugs at that time. But being the storage geek that I am, I obviously took some time to get to know Andrew the File System. 20 years have gone by, and I never really thought of AFS coming out as a commercial solution or even knew of it as one, until Auristor®,

The Starbucks model for Storage-as-a-Service

Starbucks™ is not a coffee shop. It purveys beyond coffee and tea, and food and puts together the yuppie beverages experience. The intention is to get the customers to stay as long as they can, and keep purchasing the Starbucks’ smorgasbord of high margin provisions in volume. Wifi, ambience, status, coffee or tea with your name on it (plenty of jokes and meme there), energetic baristas and servers, fancy coffee roasts and beans et. al. All part of the Starbucks™-as-a-Service pleasurable affair that intends to lock the customer in and have them keep coming back.

The Starbucks experience

Data is heavy and they know it

Unlike compute and network infrastructures, storage infrastructures holds data persistently and permanently. Data has to land on a piece of storage medium. Coupled that with the fact that data is heavy, forever growing and data has gravity, you have a perfect recipe for lock-in. All storage purveyors, whether they are on-premises data center enterprise storage or public cloud storage, and in between, there are many, many methods to keep the data chained to a storage technology or a storage service for a long time. The storage-as-a-service is like tying the cow to the stake and keeps on milking it. This business model is very sticky. This stickiness is also a lock-in mechanism.

Don’t go to the Clouds. Come back!

Almost in tandem last week, Nutanix™ and HPE appeared to have made denigrated comments about Cloud First mandates of many organizations today. Nutanix™ took to the annual .NEXT conference to send the message that cloud is wasteful. HPE campaigned against a UK Public Sector “Cloud First” policy.

Cloud First or Cloud Not First

The anti-cloud first messaging sounded a bit funny and hypocritical when both companies have a foot in public clouds, advocating many of their customers in the clouds. So what gives?

That A16Z report

For a numbers of years, many fear criticizing the public cloud services openly. For me, there are the 3 C bombs in public clouds.

  • Costs
  • Complexity
  • Control (lack of it)

Yeah, we would hear of a few mini heart attacks here and there about clouds overcharging customers, and security fallouts. But vendors then who were looking up to the big 3 public clouds as deities, rarely chastise them for the errors. Until recently.

The Cost of Cloud, a Trillion Dollar Paradox” released by revered VC firm Andreessen Horowitz in May 2021 opened up the vocals of several vendors who are now emboldened to make stronger comments about the shortcomings of public cloud services. The report has made it evident that public cloud services are not panacea of all IT woes.

The report has made it evident that public cloud services are not panacea of all IT woes. And looking at the trends, this will only get louder.

Use ours first. We are better

It is pretty obvious that both Nutanix™ and HPE have bigger stakes outside the public cloud IaaS (infrastructure-as-a-service) offerings. It is also pretty obvious that both are not the biggest players in this cloud-first economy. Given their weights in the respective markets, they are leveraging their positions to swing the mindsets to their turf where they can win.

“Use our technology and services. We are better, even though we are also in the public clouds.”

Not a zero sum game

But IT services and IT technologies are not a zero sum game. Both on-premises IT services and complementary public cloud services can co-exist. Both can leverage on each other’s strengths and support each other’s weaknesses, if you know how to blend and assimilate the best of both worlds. Hybrid cloud is the new black.

Gartner Hype Cycle

The IT pendulum swings. Technology hype goes fever pitch. Everyone thinks there is a cure for cancer. Reality sets in. They realize that they were wrong (not completely) or right (not completely). Life goes on. The Gartner® Hype Cycle explains this very well.

The cloud is OK

There are many merits having IT services provisioned in the cloud. Agility, pay-per-use, OPEX, burst traffic, seemingly unlimited resources and so. You can read more about it at Benefits of Cloud Computing: The pros and cons. Even AWS agrees to Three things every business needs from hybrid cloud, perhaps to the chagrin of these naysayers.

I opined that there is no single solution for everything. There is no Best Storage Technology Ever (a snarky post). And so, I believe there is nothing wrong of Nutanix™ and HPE, and maybe others, being hypocritical of their cloud and non-cloud technology offerings. These companies are adjusting and adapting to the changing landscapes of the IT environments, but it is best not to confuse the customers what tactics, strategy and vision are. Inconsistencies in messaging diminishes trust.

 

 

What the heck is Storage Modernization?

We often hear the word “modernization” thrown around these days. The push is to get the end user to refresh their infrastructure, and the storage infrastructure market is rife with modernization word. Is your storage ripe for “modernization“?

Many possibilities to modernize storage

To modernize, it has to be relative to legacy storage hardware, and the operating environment that came with it. But if the so-called “legacy” still does the job, should you modernize?

Big Data is right

When the word “Big Data” came into prominence a while back, it stirred the IT industry into a frenzy. At one point, Apache Hadoop became the poster elephant (pun intended) for this exciting new segment. So many Vs came out, but I settled with 4 Vs as the framework of my IT conversations. The 4Vs we often hear are:

  • Volume
  • Velocity
  • Variety
  • Veracity

The future of Fibre Channel in the Cloud Era

The world has pretty much settled that hybrid cloud is the way to go for IT infrastructure services today. Straddled between the enterprise data center and the infrastructure-as-a-service in public cloud offerings, hybrid clouds define the storage ecosystems and architecture of choice.

A recent Blocks & Files article, “Broadcom server-storage connectivity sales down but recovery coming” caught my attention. One segment mentioned that the server-storage connectivity sales was down 9% leading me to think “Is this a blip or is it a signal that Fibre Channel, the venerable SAN (storage area network) protocol is on the wane?

Fibre Channel Sign

Thus, I am pondering the position of Fibre Channel SANs in the cloud era. Where does it stand now and in the near future? Continue reading

Data Sovereignty – A boon or a bane?

Data across borders – Data Sovereignty

I really did not want to write Data Sovereignty in the way I have written it now. I wanted to write it in a happy manner, but as recent circumstances appeared, the outlook began to dim. I apologize if my commentary is bleak.

Last week started very well. I was preparing for the iXsystems™ + Nextcloud webinar on Wednesday, August 25th 2021. After talking to the wonderful folks at Nextcloud (Thanks Markus, Uwe and Maxime!), the central theme of the webinar was on Data Sovereignty and Data Control. The notion of GDPR (General Data Protection Regulation) has already  permeated into EU (European Union) entities, organizations and individuals alike, and other sovereign states around the world are following suit. Prominent ones on my radar in the last 2 years were the California Consumer Privacy Act (CCPA) and Vietnam Personal Data Protection Act 2020.

What If – The other side of Storage FUDs

Streaming on Disney+ now is Marvel Studios’ What If…? animated TV series. In the first episode, Peggy Carter, instead of Steve Rogers, took the super soldier serum and became the first Avenger. The TV series explores alternatives and possibilities of what we may have considered as precept and the order of things.

As storage practitioners, we are often faced with certain “dogmatic” arguments which were often a mix of measured actuality and marketing magic – aka FUD (fear, uncertainty, doubt). Time and again, we are thrown a curve ball, like “Oh, your competitor can do this. Can you?” Suddenly you are feeling pinned to a corner, and the pressure to defend your turf rises. You fumbled; You have no answer; Game over!

I experienced these hearty objections many times over. The best experience was one particular meeting I had during my early days with NetApp® in 2000. I was only 1-2 months with the company, still wet between the ears with the technology. I was pitching the SnapMirror® to Ericsson Malaysia when the Scandinavian manager said, “I think you are lying!“. I was lost without a response. I fumbled spectacularly although I couldn’t remember if we won or lost that opportunity.

Here are a few I often encountered. Let’s play the game of What If …?

What If …?
