Ho hum. Another day, and another data leak. What else is new?

The latest hullabaloo in my radar was from one of Malaysia’s reverent universities, UiTM, which reported a data leak of 11,891 student applicants’ private details including MyKad (national identity card) numbers of each individual. Reading from the news article, one can deduced that the unsecured link mentioned was probably from a cloud storage service, i.e. file synchronization software such as OneDrive, Google Drive, Dropbox, etc. Those files that can be easily shared via an HTTP/S URL link. Ah, convenience over the data security best practices. 

Cloud File Sync software

It irks me when data security practices are poorly practised. And it is likely that there is ignorance of data security practices in the first place.

It also irks me when many end users everywhere I have encountered tell me their file synchronization software is backup. That is just a very poor excuse of a data protection strategy, if any, especially in enterprise and cloud environments. Convenience, set-and-forget mentality. Out of sight. Out of mind. Right? 

Convenience is not data security. File Sync is NOT Backup

Many users are used to the convenience of file synchronization. The proliferation of cloud storage services with free Gigabytes here and there have created an IT segment based on BYOD, which transformed into EFSS, and now CCP. The buzzword salad involves the Bring-Your-Own-Device, which evolved into Enterprise-File-Sync-&-Share, and in these later years, Content-Collaboration-Platform.

All these are fine and good. The data industry is growing up, and many are leveraging the power of file synchronization technologies, be it on on-premises and from cloud storage services. Organizations, large and small, are able to use these file synchronization platforms to enhance their businesses and digitally transforming their operational efficiencies and practices. But what is sorely missing in embracing the convenience and simplicity is the much ignored cybersecurity housekeeping practices that should be keeping our files and data safe.

Reverting the Cloud First mindset

By | | , , , , , , , , ,

When cloud computing was all the rage, every business wanted to be on-board. Those who resisted felt the heat as the FOMO (fear of missing out) feeling set in, especially those who were doing this thing called “Digital Transformation“. The public cloud service providers took advantage of the cloud computing frenzy, calling for a “Cloud First” strategy. For a number of years, the marketing worked. The cloud first mentality became the tip of the tongue of many, encouraging droves to cloud adoption.

All this was fine and dandy but recently, we are beginning to hear and read about a few high profile cases of cloud repatriation. DHH‘s journal of Basecamp’s exit from AWS in late 2022 reverberated strongly, saying what should be a wake up call for those caught in the Cloud Computing Hotel California’s gilded cage. An even more bizarre claim about cost savings of $400 million over 3 years was made by Ahrefs, a Singapore SEO software maker which chose to use a co-location facility instead of a public cloud service.

Cloud First is not Cool (not sure where is the source is from but I got this off Twitter some months ago)

While these big news jail breaks are going against the grain, most are still in that diaspora to jump into the cloud services everywhere. In droves even. But, on and off, I am beginning to hear some grips, grunts and groans from end users in the cloud. These news have emboldened some to think that there is another choice besides shifting all IT and data services to the cloud.

Project COSI

The S3 (Simple Storage Service) has become a de facto standard for accessing object storage. Many vendors claim 100% compatibility to S3, but from what I know, several file storage services integration and validation with the S3 have revealed otherwise. There are certain nuances that have derailed some of the more advanced integrations. I shall not reveal the ones that I know of, but let us use this thought as a basis of our discussion for Project COSI in this blog.

Project COSI high level architecture

What is Project COSI?

COSI stands for Container Object Storage Interface. It is still an alpha stage project in Kubernetes version 1.25 as of September 2022 whilst the latest version of Kubernetes today is version 1.26. To understand the objectives COSI, one must understand the journey and the challenges of persistent storage for containers and Kubernetes.

For me at least, there have been arduous arguments of provisioning a storage repository that keeps the data persistent (and permanent) after containers in a Kubernetes pod have stopped, or replicated to another cluster. And for now, many storage vendors in the industry have settled with the CSI (container storage interface) framework when it comes to data persistence using file-based and block-based storage. You can find a long list of CSI drivers here.

However, you would think that since object storage is the most native storage to containers and Kubernetes pods, there is already a consistent way to accessing object storage services. From the objectives set out by Project COSI, turns out that there isn’t a standard way to provision and accessing object storage as compared to the CSI framework for file-based and block-based storage. So the COSI objectives were set to:

  • Kubernetes Native – Use the Kubernetes API to provision, configure and manage buckets
  • Self Service – A clear delineation between administration and operations (DevOps) to enable self-service capability for DevOps personnel
  • Portability – Vendor neutrality enabled through portability across Kubernetes Clusters and across Object Storage vendors

Further details describing Project COSI can be found here at the Kubernetes site titled “Introducing COSI: Object Storage Management using Kubernetes API“.

Standardization equals technology adoption

Standardization means consistency, control, confidence. The higher the standardization across the storage and containerized apps industry, the higher the adoption of the technology. And given what I have heard from the industry over these few years, Kubernetes, to me, even till this day, is a platform and a framework that are filled and riddled with so many moving parts. Many of the components looks the same, feels the same, and sounds the same, but might not work out the same when deployed.

Therefore, the COSI standardization work is important and critical to grow this burgeoning segment, especially when we are rocketing towards disaggregation of computing service units, resources that be orchestrated to scale up or down at the execution of codes. Infrastructure-as-Code (IAC) is becoming a reality more and more with each passing day, and object storage is at the heart of this transformation for Kubernetes and containers.

Fibre Channel Protocol in a Zero Trust world

By | | , , , , , , , , ,

Fibre Channel SANs (storage area networks) are touted as more secure than IP-based storage networks. In a way, that is true because Fibre Channel is a distinct network separated from the mainstream client-based applications. Moreover, the Fibre Channel protocol is entirely different from IP, and the deep understanding of the protocol, its implementations are exclusive to a selected cohort of practitioners and professionals in the storage technology industry.

The data landscape has changed significantly compared to the days where FC SANs were dominating the enterprise. The era was the mid 90s and early 2000s. EMC® was king; IBM® Shark was a top-tier predator; NetApp® was just getting over its WAFL™ NAS overdose to jump into Fibre Channel. There were other fishes in the Fibre Channel sea.

But the sands of storage networking have been shifting. Today, data is at the center of the universe. Data is the prized possession of every organization, and has also become the most coveted prize for data thieves, threat actors and other malefactors in the digital world. The Fibre Channel protocol has been changing too, under its revised specifications and implementations through its newer iterations in the past decade. This change in advancement of Fibre Channel as a storage networking protocol is less often mentioned, but nevertheless vital in the shift of the Fibre Channel SANs into a Zero Trust world.

Zones, masks and maps

Many storage practitioners are familiar with the type of security measures employed by Fibre Channel in the yesteryears. And this still rings true in many of the FC SANs that we know of today. For specific devices to connect to each other, from hosts to the storage LUNs (logical unit numbers), FC zoning must be configured. This could be hard zoning or soft zoning, where the concept involves segmentation and the grouping of configured FC ports of both the ends to “see” each other and to communicate, facilitated by the FC switches. These ports are either the initiators or the storage target, each with its own unique WWN (World Wide Name).

On top of zoning, storage practitioners also configure LUN masking at the host side, where only certain assigned LUNs from the storage array is “exposed” to the specific host initiators. In conjunction, at the storage array side, the LUNs are also associated to only a group of host initiators that are allowed to connect to the selected LUNs. This is the LUN mapping part.

Societies in crisis. Data at Fault

The deluge of data is astounding. We get bombarded and attacked by data every single waking minute of our day. And it will get even worse. Our senses will be numbed into submission. In the end, I ask in the sense of it all. Do we need this much information force fed to us at every second of our lives?

We have heard about the societies a decade ago living in the Information Age and now, we have touted the Social Age. TikTok, Youtube, Twitter, Spotify, Facebook, Metaverse(s) and so many more are creating societies that are defined by data, controlled by data and governed by data. Data can be gathered so easily now that it is hard to make sense of what is relevant or what is useful. Even worse, private data, information about the individual is out there either roaming without any security guarding it, or sold like a gutted fish in the market. The bigger “whales” are peddled to the highest bidder. So, to the prudent human being, what will it be?

Whatever the ages we are in, Information or Social, does not matter anymore. Data is used to feed the masses; Data is used to influence the population; Data is the universal tool to shape the societies, droning into submission and ruling them to oblivion.

Societies burn

GIGO the TikTok edition

GIGO is Garbage In Garbage Out. It is an age old adage to folks who have worked with data and storage for a long time. You put in garbage data, you get garbage output results. And if you repeat the garbage in enough times, you would have created a long lasting garbage world. So, imagine now that the data is the garbage that is fed into the targeted society. What will happen next is very obvious. A garbage society.

Should you bash your Storage competitor?

By | | , , ,
3 Comments

I get disturbed whenever a reseller, or even an end user asks for a competitive statement about storage Brand X or storage Brand Y. Given my background of everything storage, many a times, they want me to “dish the dirty stuff” of the storage brands I am competing with. And I often resist. Here is my philosophy and my approach.

Many storage consultants love to say bad things about others. It is one of the ways to get a bright glow about the product(s) they are pitching, and dim the prospects of their competitors. I don’t like to do things this way because what I say reflect on my professional ethos. In the closely connected storage networking and technology industry, we have folks that make career moves from one company to their competitors. Heck, I have a friend who recently joined Hitachi Vantara® after almost 20 years at EMC® (now Dell EMC®). We make career choices but it does not mean we should take the moral low ground to bash which storage competitor we are facing at that moment.

Where do I start?

This blog

The motivation to write this blog came from an article from CRN where NetApp®’s CEO, George Kurian, “corrected” Pure Storage®’s CEO Charles Giancarlo about his “inaccurate” statements about “true cloud storage”. Whatever Charlie said may be innocuous, but it has certainly stung Georgie. 

And in any technology-based industry, this technology bashing habit is rampant. Like it or not, marketing has played a role in creating the perception and the aura of strength with the technology it represents. Over the years, I have my fair share of beliefs cultivated through marketing, although as I wizened over the last 2 decades, I spend a lot of time diving deep into the specific storage technology. If time and resources permit, I even do technical hands-on, just to understand the technology more intimately. And that became the basis of running this StorageGaga blog in the past 12 years. To go beyond the FUDs and the fluffs, and share meaningful details and knowledge. Through my sharing, I learn from others as well.

Open Source on my mind

By | | , , , , , , , , , , , , , ,
2 Comments

Last week was cropped with topics around Open Source software. I want to voice my opinions here (with a bit of ranting) and hoping not to rouse many abhorrent comments from different parties and views. This blog is to create conversations, even controversial ones, but we must first agree that there will be disagreements. We must accept disagreements as part of this conversation.

In my 30 years career, Open Source has been a big part of my development and progress. The ideas of freely using (certain) software without any licensing implications and these software being openly available were not always welcomed, as they are now. I think the Open Source revolution has created an innovation movement that is still going strong, and it has not only permeated completely into the IT industry, Open Source has also now in almost every part of the technology-based industries as well. The Open Source influence is massive.

Open Source word cloud

In the beginning

In the beginning, in my beginning in 1992, the availability of software and its source codes was a closed one. Coming from a VAX/VMS background (I was a system admin in my mathematics department’s mini computers), Unix liberated my thinking. The final 6 months in the university was systems programming in C, and it completely changed how I wanted my career to shape. The mantra of “Free as in Freedom” in General Public License GPL (which I got know of much later) boded well with my own tenets in life.

If closed source development models led to proprietary software and a centralized way to distributing software with license, I would count the Open Source development models as one of the earliest decentralized technology frameworks. Down with the capitalistic corporations (aka Evil Empires)!

It was certainly a wonderful and generous way to make the world that it is today. It is a better world now.

Beyond the WORM with MinIO object storage

By | | , , , , , , , , , , , , , , , , , ,

I find the terminology of WORM (Write Once Read Many) coming back into the IT speak in recent years. In the era of rip and burn, WORM was a natural thing where many of us “youngsters” used to copy files to a blank CD or DVD. I got know about how WORM worked when I learned that the laser in the CD burning process alters the chemical compound in a segment on the plastic disc of the CD, rendering the “burned” segment unwritable once it was written but it could be read many times.

At the enterprise level, I got to know about WORM while working with tape drives and tape libraries in the mid-90s. The objective of WORM is to save and archive the data and files in a non-rewritable format for compliance reasons. And it was the data compliance and data protection parts that got me interested into data management. WORM is a big deal in many heavily regulated industries such as finance and banking, insurance, oil and gas, transportation and more.

Obviously things have changed. WORM, while very much alive in the ageless tape industry, has another up-and-coming medium in Object Storage. The new generation of data infrastructure and data management specialists are starting to take notice.

I take this opportunity to take MinIO object storage for a spin in creating WORM buckets which can be easily architected as data compliance repositories with many applications across regulated industries. Here are some relevant steps.

Truthful information under attack. The call for Data Preservation

The slogan of The Washington Post is “Democracy Dies in Darkness“. Although not everyone agrees with the US brand of democracy, the altruism of WaPo‘s (the publication’s informal name) slogan is a powerful one. The venerable newspaper remains the beacon in the US as one of the most trustworthy sources of truthful, honest information.

Misinformation

Misinformation has become a clear and present danger to humanity. Fake news, misleading information, lies are fueling and propelling the propaganda and agenda of the powerful (and the deranged). Facts are blurred, obfuscated, and even removed and replaced with misinformation to push for the undesirable effects that will affect the present and future generations.

The work of SNIA®

Data preservation is part of Data Management. More than a decade ago, SNIA® has already set up a technical work group (TWG) on Long Term Retention and proposed a format for long-term storage of digital format. It was called SIRF (Self-contained Information Retention Format). In the words of SNIA®, “The SIRF format enables long-term physical storage, cloud storage and tape-based containers effective and efficient ways to preserve and secure digital information for many decades, even with the ever-changing technology landscape.”

I don’t think battling misinformation was SNIA®’s original intent, but the requirements for a vendor-neutral organization as such to present and promote long term data preservation is more needed than ever. The need to protect the truth is paramount.

SNIA® continues to work with many organizations to create and grow the ecosystem for long term information retention and data preservation.

NFTs can save data

Despite the hullabaloo of NFTs (non-fungible tokens), which is very much soiled and discredited by the present day cryptocurrency speculations, I view data (and metadata) preservation as a strong use case for NFTs. The action is to digitalize data into an NFT asset.

Here are a few arguments:

  1. NFTs are unique. Once they are verified and inserted into the blockchain, they are immutable. They cannot be modified, and each blockchain transaction is created with one never to be replicated hashed value.
  2. NFTs are decentralized. Most of the NFTs we know of today are minted via a decentralized process. This means that the powerful cannot (most of the time), effect the NFTs state according to its whims and fancies. Unless the perpetrators know how to manipulate a Sybil attack on the blockchain.
  3. NFTs are secure. I have to set the knowledge that NFTs in itself is mostly very secure. Most of the high profiled incidents related to NFTs are more of internal authentication vulnerabilities and phishing related to poor security housekeeping and hygiene of the participants.
  4. NFTs represent authenticity. The digital certification of the NFTs as a data asset also define the ownership and the originality as well. The record of provenance is present and accounted for.

Since NFTs started as a technology to prove the assets and artifacts of the creative industry, there are already a few organizations that playing the role. Orygin Art is one that I found intriguing. Museums are also beginning to explore the potential of NFTs including validating and verifying the origins of many historical artifacts, and digitizing these physical assets to preserve its value forever.

The technology behind NFTs are not without its weaknesses as well but knowing what we know today, the potential is evident and power of the technology has yet to be explored fully. It does present a strong case in preserving the integrity of truthful data, and the data as historical artifacts.

Protect data safety and data integrity

Misinformation is damaging. Regardless if we believe the Butterfly Effect or not, misinformation can cause a ripple effect that could turn into a tidal wave. We need to uphold the sanctity of Truth, and continue to protect data safety and data integrity. The world is already damaged, and it will be damaged even more if we allow misinformation to permeate into the fabric of the global societies. We may welcome to a dystopian future, unfortunately.

This blog hopes to shake up the nonchalant state that we view “information” and “misinformation” today. There is a famous quote that said “Repeat a lie often enough and it becomes the truth“. We must lead the call to combat misinformation. What we do now will shape the generations of our present and future. Preserve Truth.

WaPo “Democracy Dies in Darkness”

[ Condolence: Japan Prime Minister, Shinzo Abe, was assassinated last week. News sources mentioned that the man who killed him had information that the slain PM has ties to a religious group that bankrupted his mother. Misinformation may played a role in the killing of the Japanese leader. ]

TrueNAS SCALE Clustered SMB to the fore

iXsystems™ released second iteration of TrueNAS® SCALE software just over a week ago. It is known as version 22.02.2 or Anglefish.2, with the most notable upgrades to HA (High Availability) for SCALE and Clustered SMB capabilities. This is the perfect excuse for me to learn about Clustered SMB and share what I have learned.

TrueNAS SCALEFor the

For the uninformed, Clustered SMB brings highly available SMB file sharing services to mission critical environments. More importantly, Clustered SMB is high availability in a scale-out clustered architecture.

My view beyond HA SMB

I am not familiar with Clustered SMB in a NAS (Network Attached Storage). The world I am more familiar with is either having CIFS/SMB file services on a dual controller storage appliance or running Windows File Sharing on an Microsoft® Clustered Service (MSCS). Typically in these 2 types of HA SMB services, the scale up architecture require a shared access to a consolidated storage volume. Behind the scenes, there are many mechanisms at play to ensure that one, and only one, storage controller or HA host can have write access capabilities at one time. The most common mechanism is the SCSI-3 Persistent Reservation or sometimes known as SCSI fencing, using the SPC-3 (SCSI Primary Command) primitives. The whole objective is to prevent 2 nodes or hosts to writing to the shared storage volume at the same time and other issues like split-brain.
