server storage I/O data infrastructure trends

Updated 1/21/2018

Introducing Windows Subsystem for Linux WSL and Overview. Microsoft has been increasing their support of Linux across Azure public cloud, Hyper-V and Linux Integration Services (LIS) and Windows platforms including Windows Subsystem for Linux (WSL) as well as Server along with Docker support.

WSL installed with Ubuntu on Windows 10

WSL with Ubuntu installed and open in a window on one of my Windows 10 systems.

WSL is not a virtual machine (VM) running on Windows or Hyper-V, rather it is a subsystem that coexists next to win32 (read more about how it works and features, enhancements here). Once installed, WSL enables use of Linux bash shell along with familiar tools (find, grep, sed, awk, rsync among others) as well as services such as ssh, MySQL among others.

What this all means is that if you work with both Windows and Linux, you can do so on the same desktop, laptop, server or system using your preferred commands. For example in one window you can be using Powershell or traditional Windows commands and tools, while in another window working with grep, find and other tools eliminating the need to install things such as wingrep among others.

Installing WSL

Depending on which release of Windows desktop or server you are running, there are a couple of different install paths. Since my Windows 10 is the most recent release (e.g. 1709) I was able to simply go to the Microsoft Windows Store via desktop, search for Windows Linux, select the distribution, install and launch. Microsoft has some useful information for installing WSL on different Windows version here, as well as for Windows Servers here.

Get WSL from Windows Store

Get WSL from Windows Store or more information and options here.

Microsoft WSL install

Click on Get the app

Select which Linux for WSL to install

Select desired WSL distribution

SUSE linux for WSL

Lests select SUSE as I already have Ubuntu installed (I have both)

WSL installing SUSE

SUSE WSL in the process of downloading. Note SUSE needs an access code (free) that you get from https://www.suse.com/subscriptions/sles/developer/ while waiting for the download and install is a good time to get that code.

launching WSL on Windows 10

Launching WSL with SUSE, you will be prompted to enter the code mentioned above, if you do not have a code, get it here from SUSE.

completing install of WSL

The WSL installation is very straight forward, enter the SUSE code (Ubuntu did not need a code). Note the Ubuntu and SUSE WSL task bar icons circled bottom center.

Ubuntu and SUSE WSL on Windows 10

Provide a username for accessing the WSL bash shell along with password, confirm how root and sudo to be applied and that is it. Serious, the install for WSL at least with Windows 10 1709 is that fast and easy. Note in the above image, I have WSL with Ubuntu open in a window on the left, WSL with SUSE on the right, and their taskbar icons bottom center.

Windows WSL install error 0x8007007e

Enable Windows Subsystem for Linux Feature on Windows

If you get the above WSL error message 0x8007007e when installing WSL Ubuntu, SUSE or other shell distro, make sure to enable the Windows WSL feature if not already installed.

Windows WSL install error fix

One option is to install additional Windows features via settings or control panel. For example, Control panel -> Programs and features -> Turn Windows features on or off -> Check the box for Windows Subsystem for Linux

Another option is to install Windows subsystem feature via Powershell for example.

enable-windowsoptionalfeature -online  -featurename microsoft-windows-subsystem-linux

Using WSL

Once you have WSL installed, try something simple such as view your present directory:

pwd

Then look at the Windows C: drive location

ls /mnt/c -al

In case you did not notice the above, you can use Windows files and folders from the bash shell by placing /mnt in front of the device path. Note that you need to be case-sensitive such as User vs. user or Documents vs. documents.

As a further example, I needed to change several .htm, .html, .php and .xml files on a Windows system whose contents had not yet changed from https://storageio.com to https://storageio.com. Instead of installing wingrep or some tools, using WSL such as with Ubuntu finding files can be done with grep such as:

grep "https://storageio.com" /mnt/c/Users/*.xml

And then making changes using find and sed such as:

find /mnt/c/Users -name \*.xml -exec sed  -i "s,https://storageio.com,https://storageio.com,g" {} \;

Note that not all Linux apps and tools can use file via /mnt in which case a solution is to create a symbolic link.

For example:

ln -s "/mnt/c/Users/Test1/Documents"  /home/Test1/Projects

What This All Means

If you primarily work on (or have a preference for) Linux systems and need to do some functions from development to the administration or other activity on a Windows system, Windows Subsystem for Linux (WSL) provides a bash shell to do familiar tasks. Likewise, if you are primarily a Windows person and need to brush up on your Linux skills, WSL can help. If you need to run Linux server applications or workloads, put those into a Docker container, Hyper-V instance or Azure VM.

Overall I like WSL for what it is, a tool that eliminates the need of having to install several other tools to do common tasks, plus makes it easier to work across various Linux and Windows systems including bare metal, virtual and cloud-based. Now that you have been introduced to Windows Subsystems for Linux WSL and an overview including install as well as using, add it to your data infrastructure toolbox.

Data Infrastructure Server Storage I/O Tradecraft Trends

Data Infrastructure Server Storage I/O Tradecraft Trends

Data Infrastructure trends include server storage I/O network and associated tradecraft are your skills, experiences, insight as well as tricks of the trade, profession and job function (read more about what is a data infrastructure here).

This is the second of a two-part series exploring data infrastructure along with serve storage I/O and related tradecraft. Read part one of this series here.

Data Infrastructures
Data Infrastructure and IT Infrastructure Layers

As a refresher from part one, data infrastructure encompasses servers, storage, I/O and networking along with associated hardware, software, services and management tasks including data protection among others. Tradecraft is knowing about tools, technologies, and trends in your primary domain as well as adjacent focus areas. However, tradecraft is also about knowing how and when to use different technologies, tools with various techniques to address different scenarios.

Tradecraft Trends
Trends involving tradecraft include capturing existing experiences and skills from those who are about to retire or simply move on to something else, as well as learning for those new to IT or servers, storage, I/O, and data infrastructure hardware, software, and services. This means being able to find a balance of old and new tools, techniques, and technologies, including using things in new ways for different situations.

Part of expanding your tradecraft skill set is knowing when to use different tools, techniques, and technologies from proprietary and closed to open solutions, from tightly integrated to loosely integrated, to bundled and converged, or to a la carte or unbundled components, with do-it-yourself (DIY) integration.

Tradecraft also means being able to balance when to make a change of technology, tool, or technique for the sake of change vs. clinging to something comfortable or known, vs. leveraging old and new in new ways while enabling change without disrupting the data infrastructure environment or users of its services.

A couple of other trends include the convergence of people and positions within organizations that may have been in different silos or focus areas in the past. One example is the rise of Development Operations (also known as DevOps), where instead of separate development, administration, and operations areas, they are a combined entity. This might be déja vu for some of you who grew up and gained your tradecraft in similar types of organizations decades ago; for others, it may be something new.

Regarding fundamental tradecraft skills, if you are a hardware person it is wise to learn software; if you are a software person, it is advisable to acquire some hardware experience. Also, don’t be afraid to say “I do not know” or “it depends on on” when asked a question. This also means learning how information technology supports the needs of the business, as well as learning the technology the business uses.

Put another way, in addition to learning server storage I/O hardware and software tradecraft, also learn the basic tradecraft of the business your information systems are supporting. After all, the fundamental role of IT is to protect, preserve, and serve information that enables the company or organization; no business exists just to support IT.

Data Infrastructure Tool Box

How to develop tradecraft?
There are many ways, including reading this book along with the companion websites as well as other books, attending seminars and webinars, participating in forums and user groups, as well as having a test lab to learn and try things. Also, find a mentor you can learn from to help capture some of his or her tradecrafts, and if you are experienced, become a mentor to help others develop their tradecraft.

Toolbox tips, reminders, and recommendations:

  • Create a virtual, software-defined, and physical toolbox.
  • Include tip sheets, notes, hints, tricks, and shortcuts.
  • Leverage books, blogs, websites, tutorials, and related information.
  • Implement a lab or sandbox to try things out
  • Do some proof of concepts (POC) and gain more experience

Tradecraft Tips
Get some hands-on, behind-the-wheel time with various technologies to gain insight, perspective, and appreciation of what others are doing, as well as what is needed to make informed decisions about other areas. This also means learning from looking at demos, trying out software, tools, services, or using other ways to understand the solution. Knowing about the tools and technology is important; however, so too is knowing how to use a tool (techniques) and when along with where or for what. This means knowing the tools in your toolbox, but also knowing when, where, why, and how to use a given tool (or technology), along with techniques to use that tool by itself or with multiple other tools.

Additional tips and considerations include:

  • Expand your social and technical network into adjacent areas.
  • Get involved in user groups, forums, and other venues to learn and give back.
  • Listen, learn, and comprehend vs. only memorizing to pass a test.
  • Find a mentor to help guide you, and become a mentor to help others.
  • Collaborate, share, respect and be respected; the accolades will follow.
  • Evolve from focus on certificates or credentials to expansion of experiences.
  • Connect with others to expand your network

What this means

Remember that tradecraft is skills, experiences, tricks, and techniques along with knowing what as well as how to use various related tools as part of what it is that you are doing. Your data infrastructure tradecraft is (or should be):

  • Essential skills and experiences spanning different technologies and focus areas
  • Knowing various techniques to use new and old things in new as well as hybrid ways
  • Expanding awareness into adjacent areas around your current focus or interest areas
  • Leveraging comprehension, understanding application of what you know
  • Evolving with new knowledge, experiences, and insight about tools and techniques
  • Hardware, software, services, processes, practices, and management
  • From legacy to software-defined, cloud, virtual, and containers

Part of server storage I/O data infrastructure tradecraft is understanding what tools to use when, where, and why, not to mention knowing how to adapt with those tools, find new ones, or create your own.

Remember, if all you have is a hammer, everything starts to look like a nail. On the other hand, if you have more tools than you know what to do with, or how to use them, perhaps fewer tools are needed along with learning how to use them by enhancing your skillset and tradecraft.

In-between the known data infrastructure server, storage, I/O network, converged infrastructure (CI), hyper-converged infrastructure (HCI), Docker and other containers, cloud, hardware software-defined known, and unknown is your tradecraft. The narrow the gap between the known and the unknown as well as how to apply your experience is the diversity of your tradecraft.

Server Storage I/O network Data Infrastructure Tradecraft Overview

Server Storage I/O network Data Infrastructure Tradecraft Overview

Updated 1/17/2018

Data Infrastructure Tradecraft includes server storage I/O network and associated technology, technique, skills, experiences. Tradecraft includes insight as well as tricks of the trade, profession and job function (read more about what is a data infrastructure here). This is the first of a two-part series exploring data infrastructure along with serve storage I/O and related tradecraft. Read part two of this series here.

Data Infrastructures Tradecraft Overview
Data Infrastructure and IT Infrastructure Layers

Data infrastructure encompasses servers, storage, I/O and networking along with associated hardware, software, services and management tasks including data protection among others. Tradecraft is knowing about tools, technologies, and trends in your primary domain as well as adjacent focus areas. However, tradecraft is also about knowing how and when to use different technologies, tools with various techniques to address different scenarios.

What Is Your Tradecraft
An example of expanding tradecraft is, for instance, an automobile technician who has learned how to change oil, check tire air pressure, or other essential entry-level functions. On the other hand, a master mechanic knows how to do more involved tasks, from the engine to transmission repair or rebuilding, bodywork, along with troubleshooting. A master mechanic not only knows what buttons, knobs, tools, and techniques to use for different tasks, he also knows how to diagnose problems, as well as what usually causes those problems to occur.

There are many other examples, including salespeople who have the tradecraft of selling, including account as well as relationship building along with the ability to learn new tradecraft related to the trade or items they are or will be selling. Moreover, then there are pre-sales and systems engineers, technical marketing, product and program management, test and development, R&D engineering, IT and technology architects, among many others.
IT Data Infrastructure Professionals

Another example is engineers and architects (non-IT) who have basic design along with engineering discipline tradecraft, as well as specialties such as mechanical, electrical, heating ventilation air condition (HVAC), or environmental, among others. They can leverage their basic tradecraft while extending and enhancing it by gaining insight as well as experience in adjacent areas of focus.

For IT and data infrastructure tradecraft this means expanding from basic tasks to being able to do more advanced things. For example, developing tradecraft from knowing the different hardware, software, and services resources as well as tools, to what to use when, where, why, and how. Another dimension of expanding data infrastructure tradecraft skills is gaining the experience and insight to troubleshoot problems, gain insight awareness with dashboard or monitoring tools, as well as how to design and manage to cut or reduce the chance of things going wrong.

From Tools and Technologies to Techniques and Tricks of the Trade
Expanding your awareness of new technologies along with how they work is important, so too is understanding application and organization needs. Developing your tradecraft means balancing the focus on new and old technologies, tools, and techniques with business or organizational application functionality.

This is where using various tools that themselves are applications to gain insight into how your data infrastructure is configured and being used, along with the applications they support, is important.

Data Infrastructure Tool Box

Learning the Talk and Walking the Talk
For some people their tradecraft is only learning the talk, so that they can talk the talk of trends, techniques, technology buzzwords to do their job (or get a job) and fit in. The next step is comprehending the talk, gaining more insight and experience ability of what to do (and not do) by walking the talk. Sometimes this means learning from mistakes (yours or others) to prevent them in the future.

Expanding your tradecraft means learning the talk as well as how to walk the talk for adjacent areas. This can mean new skills, ability, tools, and technologies along with proper terminology. For your data infrastructure tradecraft, you need to acquire competencies in these different yet related areas.

Even if your focus is to be a hardware or software or services person, there are opportunities to expand your tradecraft. For example extend into physical, virtualization, cloud, container, networking, storage, performance, data protection, or security, among others. This also means comprehending how the pieces work together to support the business applications, as well as the impact on each other (e.g. cause and effect).

Part of tradecraft is also understanding that various terms and acronyms have different context meaning. For example, SAS can mean big data statistical analysis software or Serial Attached SCSI among others. What this means is as your tradecraft expands, so too does awareness that different terms have various meaning along with the importance of asking for context.

Another example of understanding context is Fabric. Fabric can also have different context and meaning. It can refer to a network of switches, directors, and routers tying together servers, storage, bridges, gateways, and other devices, but it can also be associated with higher-level application functions, or a cluster of servers or services, as well as data. Keep context in mind about fabric: whether it is referring to lower-level physical and logical networks, or applications and data, among others.

Yet another context example includes that client can have different meanings, including software or applications that communicate with a server or service, local or in the cloud. A variation of client can also be a type of device, such as a tablet, laptop, mobile device or phone, as well as a workstation with varying software for accessing different data infrastructure as well as applications. Another context for client is the user, person, or thing such as IoT that accesses and interacts with client software or server and services of application or data resources. Yet another context for client is a consumer of lower-level data infrastructure resources or higher-level applications services.

Old School, New School, Current and Back to School (With Poll)

Storage I/O trends

Old School, New School, Current and Back to School

Are you old school or new school?

If you are new school or old school, then will you be stuck on those school’s of thought or advanced to the current and future schools?

Old School

From the old school folks you will hear things along the lines of that is how we do or did it. Also you might hear things along the lines of lets use what we have as long as we can make it work to fix problems while learning from mistakes. Also from old school you may here things like new school is only focused on the newest latest greatest shiny technology. Not to mention themes such as we have to stick around and clean up and take care of the mess left when new schoolers move to their next focus.

New School

On the other hand from new school you may hear snarky comments about old school either in kidding and jest, as a way to put down to promote self up in status. Some other new school perspectives are focus on the newest technology that can be used wherever with focus on the tool, product or service as opposed to sometimes lack of focus on the problem to address. Another theme can be don’t worry about the future, we will either throw away what we have and get something new, or leave it up to somebody else to take care, after all, the old schoolers are good at doing that.

Current and Future School

Storage I/O trends

Then there are the current and future schoolers that are hybrid, combing the best of old-school leveraging their experiences with openness to explore new things of the new schoolers. The current or future schoolers are a blend of risk-averse yet willing to explore and find new ways to fix problems vs. simply moving, masking or leaving issues behind. The new or current schoolers are keen on learning lessons and mistakes of the past to avoid making them in the future.

Likewise they are also dialed into using both new and old tools, technologies and techniques in new ways vs. simply using new things in old ways. Another characteristics of the new or future schoolers is that they are open and willing to create converged teams to leverage converged technologies. Not only are they dialed into the new technology, trends and techniques, they are also dialed into how to use them for different things, situations and apply to business or other needs as opposed to just a focus on the tech.

This means that they are willing and interested in learning other skills, crafts capabilities vs. creating old or new silos or fiefdoms of technology. These new schoolers could care less who is a cloud, virtual, server, storage, networking, database, applications, backup, security, hardware or software person as they are focused on all of those as data infrastructure professionals.

What this all means

Stay in School and be a student of the game

Some of you might be old school while others are may be new school or what ever is current trendy and cool. However new schoolers to become future or current schoolers can learn from the old schoolers. Likewise the old schoolers can learn a new thing or two as well as help transfer some knowledge experience to the new schoolers to become future schoolers. Granted old schoolers can settle in to their comfort zone while new schoolers can stay out front of the curve and both watch the rise of the new and future schoolers.

Are you old school, new school, current or no school, cast your vote and see results below:

What are some endangered IT skills species?

Dan Tynan has a good piece over at InfoWorld discussing the 9 most endangered species (e.g. skill sets) in the IT workforce. His article is along the lines that the IT job landscape is evolving rapidly and provides some ideas and points for discussion how to avoid becoming extinct.

Here is an excerpt from Dans article:

How to avoid extinction: Broaden and diversify your knowledge base now, while there’s still time, says Greg Schulz, senior adviser for the StorageIO Group, an IT infrastructure consultancy.

“If you are the hardware guy, you better start learning and embracing software,” he says. “If you are the software geek, time to appreciate the hardware. If you are infrastructure-focused, it’s time to learn about the business and its applications. You don’t want to be overgeneralized, but make sure to balance broader knowledge with depth in different areas.”

Check out Dans article to see what the other endangered skill sets are, along with other perspectives by myself and others as well as what you can do to avoid becoming extinct. Hmm, maybe read a book? ;)

Comfort Zones – Stating What Might Be Obvious to Some…

Storage I/O trends

Over the past couple of weeks I have talked with many IT professionals who work in IT data centers of varying size from different locations around the world. A couple of interesting patterns or trends if you prefer I have noticed are that while IT and storage professionals in general see disk based backup as the future and for some instances, a good tool today, there is still very much a comfort factor with magnetic tape.

The most cited reasons for continued use of tape being affordability, low power requirements, portability (assuming media is encrypted and secure) and familiar or comfort and confidence with the technology. A related trend or pattern is that while many IT professionals see the value and benefit of SSD including FLASH and RAM, there is also a concern or lack of confidence in the first so called enterprise class FLASH based SSD technology.

A related trend should hardly be a surprise in that enterprise customers I talk to who cling to tape as a data retention medium (even when using disk based backups) are also the most likely to have an early adopter aversion towards FLASH based enterprise storage. During discussions, what I also hear is that given time SSD including both RAM and enhanced or next generation FLASH will be adopted and deployed along magnetic hard disk drives (HDDs) and that HDDs will be used more in the future for backups and other data protection tasks.

Thus the consensus is that while HDDs have been declared dead by some with the arrival of FLASH and SSD, HDDs have joined the “Zombie” list of technologies declared dead, yet that continue to be produced and bought by customers. Other “Zombie” technologies include the IBM Mainframe, Fibre Channel, Magnetic Tapes, Copper based Ethernet and Printers among others. So with the magnetic HDD being over 50 years old, its safe to assume that magnetic HDD will be around for many more years, especially now that HDDs are on the “Zombie” technology list, a rather esteemed list I might add!

Ok, nuff said.
