Benefits of Moving Hyper-V Disaster Recovery to the Cloud and Achieve global cloud data availability from an Always-On approach with Veeam Cloud Connect webinar.

Feb. 28, 2018 at 11am PT / 2pm ET

Windows Server and Hyper-V software defined data center (SDDC) based applications need always on availability and access to data which means enabling cloud based data protection (including backup/recovery) for seamless disaster recovery (DR), business continuance (BC), business resiliency (BR) and high availability (HA). Key to an always on, available and accessible environment is having robust  RTO and RPO aligned to your application workload needs. In other words, time for data protection to work for you and your applications instead of you working for it (e.g. the data protection tools and technologies).

This free data protection webinar (registration required) sponsored by KeepItSafe produced by Virtualization & Cloud Review will be an interactive webinar discussion (not death by power point or Ui Gui product demo ;)) pertaining to enabling always on application (as well as data) availability for Windows Server and Hyper-V environments. Keep in mind with world backup day coming up on March 31 now is a good time to make sure your applications and data are protected as well as recoverable when something bad happens leveraging Hyper-V Disaster Recovery.

Hyper-V Disaster Recovery SDDC Data Infrastructure Data Protection

Join me along with representatives from Veeam and KeepItSafe for an informal conversation including strategies along with how to enable an always on, always available applications data infrastructure for Hyper-V based solutions.

Our conversation will include discussion around:

  • Data protection strategies for Microsoft Windows Server Hyper-V applications
  • Enabling rapid recovery time objectives (RTO) and good recovery point objectives (RPO)
  • Evolving from VM disaster recovery to cloud-based DRaaS
  • Implement 4 3 2 1 data protection availability for Hyper-V with Veeam and KeepItSafe DRaaS

Register for the live event or catch the replay here.

What this all means and wrap-up

You can not go forward if you can not go back to a particular point in time (e.g. recovery point objective or RPO). Likewise, if you can not go back to a given RPO, how can you go forward with your business as well as meet your recovery time objective (RTO)? Join us for the live conversation or replay by registering (free) here to learn how to enable robust Hyper-V Disaster Recovery and business resiliency.

Welcome to the Data Protection Diaries

Updated 1/10/2018

Storage I/O trends

Welcome to the Data Protection Diaries

This is a series of posts about data protection which includes security (logical and physical), backup/restore, business continuance (BC), disaster recovery (DR), business resiliency (BR) along with high availability (HA), archiving and related topic themes, technologies and trends.

Think of data protection like protect, preserve and serve information across cloud, virtual and physical environments spanning traditional servers, storage I/O networking along with mobile (ok, some IoT as well), SOHO/SMB to enterprise.

Getting started, taking a step back

Recently I have done a series of webinars and Google+ hangouts as part of the BackupU initiative brought to you by Dell Software (that’s a disclosure btw ;) ) that are vendor and technology neutral. Instead of the usual vendor product or technology focused seminars and events, these are about getting back to the roots, the fundamentals of what to protect when and why, then decide your options as well as different approaches (e.g. what tools to use when).

In addition over the past year (ok, years) I have also been doing other data protection related events, seminars, workshops, articles, tips, posts across cloud, virtual and physical from SOHO/SMB to enterprise. These are in addition to the other data infrastructure server and storage I/O stuff (e.g. SSD, object storage, software defined, big data, little data, buzzword bingo and others).

Keep in mind that in the data center or information factory everything is not the same as there are different applications, threat risk scenarios, availability and durability among other considerations. In this series like the cloud conversations among others, I’m going to be pulling various data protection themes together hopefully to make it easier for others to find, as well as where I know where to get them.

Virtual, Cloud and IT Availability, its a shared responsibility and common sense

IT Availability, it’s a shared responsibility and common sense

In case you missed it, recently the State of Oregon had a data center computer problem (ok, storage and application outage) that resulted in unemployment benefits not being provided. Tony Knotzer over at Network Computing did a story Oregon Storage Debacle Highlights Need To Plan For Failure and asked me for some perspectives that you can read here.

Data center

The reason I bring this incident up is not to join in the feeding frenzy that usually occurs when something like this happens, instead, to touch on what should be common. What is lacking at times (or more needed) is common sense when it comes to designing and managing flexible scalable data infrastructures.

“Fundamental IT 101 is that all technology will fail, despite what the vendors tell you,” Schulz said. And the most likely time technology will fail, he notes, is when people are involved — doing configurations, making changes or updates, or performing upgrades. – Via Network Computing

Note that while any technology can or has fail at some point, how it fails along with fault containment via design best practices and vendor resolution are important.

Good vendors learn and correct things so that they don’t happen again as well as work with customers on best practices to isolate and contain faults from expanding into disasters. Thus when a sales or marketing person tries to tell me that they have never had a failure I wonder if a: they are making something up, b: have not actually shipped to a customer in production, c: not aware of other deployments, d: towing the company line, e: too good to be true or f: all the above.

People talking

On the other hand, when a vendor tells me how they have resiliency in their product as well as processes, best practices and can even tell me (public or under NDA) how they have addressed issues, then they have my attention.

A common challenge today is cost cutting along with focus on the newest technology from servers to storage, networking to cloud, virtualization and software defined among other buzzword bingo themes and trends.

buzzword bingo

What also gets overlooked as mentioned above is common sense.

Perhaps if somebody could package and launch a good public relations campaign profiling common sense such as Software Defined Common Sense (SDCS) that might help?

On the other hand, similar to public service announcements (PSA) that may seem like common sense to some, there is a reason they are being done. That is to pass on the information to others who may not know about it thus lack what is perceived as common sense.

Lets get back to the state of Oregon’s computer systems issues and the blame game.

You know the blame game? That is when something happens or does not happen as you want it to simply find somebody else to blame or pivot and point a finger elsewhere.

the blame game

While perhaps good for CYA, the blame games usually does not help to prevent something happening again, or in the first place.

Hence in my comments about the state of Oregon computer storage system problems, I took the tone of what is common these days of no fault, shared responsibility and blame.

In other words does not matter who did what first or did not do, both sides could have prevented it.

For some this might resonate of it does not matter who misbehaved in the sandbox or play room, everybody gets a time out.

This is not to say that one side or the other has to assume or take on more blame or responsibility than the other, rather there is a shared responsibility to look out for each other.

Storage I/O trends

Just like when you drive a car, the education focus is on defensive safe driving to watch out for what the other person might do or not do (e.g. use turn signals or too busy to look in a mirror while talking or texting and driving among other things). The goal is to prevent accidents by watching out for those who are not taking responsibilities for themselves, not to mention learning from others mishaps.

teamwork
Working together vs. the blame game

Different views of customer vs. vendor

Having been a customer, as well as a vendor in the past not surprisingly I have some different views on this.

Sure the customer or client is always right, however sometimes there needs to be unpleasant conversations to help the customer help themselves, or keep themselves out of trouble.

Likewise a vendor may also take the blame when something does go wrong, even if it was entirely not their own fault just to stay in good graces with the customer or get that next deal.

Sometimes a vendor deserves to get beat up when something goes wrong, or at a least tell their story including if needed behind closed doors or under NDA. Likewise to have a meaningful relationship or partnership with the vendor, supplier or VAR, there needs to be trust and confidence which means not everything gets put out for media or blog venues to feed on.

Sure there is explaining what happened without spin, however there is also learning from mistakes to prevent them from happening which should be common sense. If part of that sharing of blame and responsibility requires being not in public that’s fine, as well as enough information of what happened is conveyed to clarify concerns and create confidence.

With vendor lockin, when I was a customer some taught that it’s the vendors fault (or for CYA, blame them), as a vendor the thinking was enforced that the customer is always right and its the competition who causes lockin.

As an analyst advisory consulting, my thinking not surprisingly is that of shared responsibility.

This means only you can allow vendor lockin, not to mention decide if lockin is bad or not.

Likewise only you can prevent data loss in cloud, virtual or traditional environments which also includes loss of access.

Granted somebody higher up the organization structure may over-ride you, however ask yourself if you did what was needed?

Likewise if a vendor is going to be doing some maintenance work in the middle of the week and there is a risk of something happening, even if they have told or sold you there is no single point of failure (NSPOF), or non disruptive upgrades.

Anytime there is a person involved regardless of if hardware, cables, software, firmware, configurations or physical environments something can happen. If the vendor drops the ball or a cable or card or something else and causes an outage or downtime, it is their responsibility to discuss those issues. However it is also the customers responsibility to discuss why they let the vendor do something during that time without taking adequate precautions. Likewise if the storage system was a single point of failure for an important system, then there is the responsibility to discuss the cost cutting concerns of others and have them justify why a redundant solution is not needed (that’s CYA 101 btw ).

Some other common sense tips

For some these might be familiar and if so, are they being done, and for others, perhaps they are new or revolutionary.

In the race to jump to a new technology or vendor, what are the unknowns? For example you may know what the issues or flaws are in an existing systems, solution, product, service or vendor, however what about the new one? Will you be the production beta customer and if so, how can you mitigate any risk?

Ask vendors tough, yet fair questions that are relevant to your needs and requirements including how they handle updates, upgrades and other tasks. Don’t be afraid to go under NDA if needed to get a better view of where they are at, have been and going to avoid surprises.

If this is not common IT sense, then take the responsibility to learn.

On the other hand, if this is common sense, take the responsibility to share and help others learn what it is that you know.

Also understand your availability needs and wants as well as balance those with costs along with risks. If something can go wrong it will if people are involved, thus design for resiliency including maintenance to offset applicable threat risks. Remember in the data center not everything is the same.

Storage I/O trends

Here is my point.

There is enough blame as well as accolades to go around, however take some shared responsibility and use it wisely.

Likewise in the race to cut cost, watch out for causing problems that compromise your information systems or services.

Look into removing complexity and costs without compromise which has long-term benefits vs. simply cutting costs.

Non Disruptive Updates, Needs vs. Wants

Storage I/O trends

Do you want non disruptive updates or do you need non disruptive upgrades?

First there is a bit of play on words going on here with needs vs. wants, as well as what is meant by non disruptive.

Regarding needs vs. wants, they are often used interchangeably particular in IT when discussing requirements or what the customer would like to have. The key differentiator is that a need is something that is required and somehow cost justified, or hopefully easier than a want item. A want or like to have item is simply that, its not a need however it could add value being a benefit although may be seen as discretionary.

There is also a bit of play on words with non disruptive updates or upgrades that can take on different meanings or assumptions. For example my Windows 7 laptop has automatic Microsoft updates enabled some of which can be applied while I work. On the other hand, some of those updates may be applied while I work however they may not take effect until I reboot or exit and restart an application.

This is not unique to Windows as my Ubuntu and Centos Linux systems can also apply updates, and in some cases a reboot might be required, same with my VMware environment. Lets not forget about applying new firmware to a server, or workstation, laptop or other device, along with networking routers, switches and related devices. Storage is also not immune as new software or firmware can be applied to a HDD or SSD (traditional or NVMe), either by your workstation, laptop, server or storage system. Speaking of storage systems, they too have new software or firmware that gets updated.

Storage I/O trends

The common theme here though is if the code (e.g. software, firmware, microcode, flash update, etc) can be applied non disruptive something known as non disruptive code load, followed by activation. With activation, the code may have been applied while the device or software was in use, however may need a reboot or restart. With non disruptive code activation, there should not be a disruption to what is being done when the new software takes effect.

This means that if a device supports non disruptive code load (NDCL) updates along with non disruptive code activation (NDCA), the upgrade can occur without disruption or having to wait for a reboot.

Which is better?

That depends, I want NDCA, however for many things I only need NDCL.

On the other hand, depending on what you need, perhaps it is both NDCL and NDCA, however also keep in mind needs vs. wants.

Ok, nuff said (for now).

In the data center or information factory, not everything is the same

StorageIO Industry trends and perspectives image

Sometimes what should be understood, or that is common sense or that you think everybody should know needs to be stated. After all, there could be somebody who does not know what some assume as common sense or what others know for various reasons. At times, there is simply the need to restate or have a reminder of what should be known.

Storage I/O data center image

Consequently, in the data center or information factory, either traditional, virtual, converged, private, hybrid or public cloud, everything is not the same. When I say not everything is the same, is that different applications with various service level objectives (SLO’s) and service level agreements (SLA’s). These are based on different characteristics from performance, availability, reliability, responsiveness, cost, security, privacy among others. Likewise, there are different size and types of organizations with various requirements from enterprise to SMB, ROBO and SOHO, business or government, education or research.

Various levels of HA, BC and DR

There are also different threat risks for various applications or information services within in an organization, or across different industry sectors. Thus various needs for meeting availability SLA’s, recovery time objectives (RTO’s) and recovery point objectives (RPO’s) for data protection ranging from backup/restore, to high-availability (HA), business continuance (BC), disaster recovery (DR) and archiving. Let us not forget about logical and physical security of information, assets and people, processes and intellectual property.

Storage IO RTO and RPO image

Some data centers or information factories are compute intensive while others are data centric, some are IO or activity intensive with a mix of compute and storage. On the other hand, some data centers such as a communications hub may be network centric with very little data sticking or being stored.

SLA and SLO image

Even within in a data center or information factory, various applications will have different profiles, protection requirements for big data and little data. There can also be a mix of old legacy applications and new systems developed in-house, purchased, open-source based or accessed as a service. The servers and storage may be software defined (a new buzzword that has already jumped the shark), virtualized or operated in a private, hybrid or community cloud if not using a public service.

Here are some related posts tied to everything is not the same:

Thus, not all things are the same in the data center, or information factories, both those under traditional management paradigms, as well as those supporting public, private, hybrid or community clouds.

Cloud conversation, Thanks Gartner for saying what has been said

StorageIO industry trends cloud, virtualization and big data

Thank you Gartner for your statements concurring and endorsing the notion of clouds can be viable, however do your homework, welcome to the club.

Why am I thanking Gartner?

Simple, I appreciate Gartner now saying what has been said for a couple of years hoping it will help to amplify the theme to the Gartner followers and faithful.

Gartner: Cloud storage viable option, but proceed carefully

Sounds like Gartner has come to the same conclusion on what has been said for several years now in posts, articles, keynotes, presentations, webinars and other venues which is when it comes to IT clouds, don’t be scared. However do your homework, be prepared, do your due diligence, proof of concepts.

Cloud conversations: Gaining cloud confidence from insights into AWS outages

StorageIO industry trends cloud, virtualization and big data

This is the first of a two-part industry trends and perspectives series looking at how to learn from cloud outages (read part II here).

In case you missed it, there were some public cloud outages during the recent Christmas 2012-holiday season. One incident involved Microsoft Xbox (view the Microsoft Azure status dashboard here) users were impacted, and the other was another Amazon Web Services (AWS) incident. Microsoft and AWS are not alone, most if not all cloud services have had some type of incident and have gone on to improve from those outages. Google has had issues with different applications and services including some in December 2012 along with a Gmail incident that received covered back in 2011.

For those interested, here is a link to the AWS status dashboard and a link to the AWS December 24 2012 incident postmortem. In the case of the recent AWS incident which affected users such as Netflix, the incident (read the AWS postmortem and Netflix postmortem) was tied to a human error. This is not to say AWS has more outages or incidents vs. others including Microsoft, it just seems that we hear more about AWS when things happen compared to others. That could be due to AWS size and arguably market leading status, diversity of services and scale at which some of their clients are using them.

Btw, if you were not aware, Microsoft Azure is more than just about supporting SQLserver, Exchange, SharePoint or Office, it is also an IaaS layer for running virtual machines such as Hyper-V, as well as a storage target for storing data. You can use Microsoft Azure storage services as a target for backing up or archiving or as general storage, similar to using AWS S3 or Rackspace Cloud files or other services. Some backup and archiving AaaS and SaaS providers including Evault partner with Microsoft Azure as a storage repository target.

When reading some of the coverage of these recent cloud incidents, I am not sure if I am more amazed by some of the marketing cloud washing, or the cloud bashing and uniformed reporting or lack of research and insight. Then again, if someone repeats a myth often enough for others to hear and repeat, as it gets amplified, the myth may assume status of reality. After all, you may know the expression that if it is on the internet then it must be true?

Have AWS and public cloud services become a lightning rod for when things go wrong?

Here is some coverage of various cloud incidents:

The above are a small sampling of different stories, articles, columns, blogs, perspectives about cloud services outages or other incidents. Assuming the services are available, you can Google or Bing many others along with reading postmortems to gain insight into what happened, the cause, effect and how to prevent in the future.

Do these recent incidents show a trend of increased cloud outages? Alternatively, do they say that the cloud services are being used more and on a larger basis, thus the impacts become more known?

Perhaps it is a mix of the above, and like when a magnetic storage tape gets lost or stolen, it makes for good news or copy, something to write about. Granted there are fewer tapes actually lost than in the past, and far fewer vs. lost or stolen laptops and other devices with data on them. There are probably other reasons such as the lightning rod effect given how much industry hype around clouds that when something does happen, the cynics or foes come out in force, sometimes with FUD.

Similar to traditional hardware or software based product vendors, some service providers have even tried to convince me that they have never had an incident, lost or corrupted or compromised any data, yeah, right. Candidly, I put more credibility and confidence in a vendor or solution provider who tells me that they have had incidents and taken steps to prevent them from recurring. Granted those steps might be made public while others might be under NDA, at least they are learning and implementing improvements.

As part of gaining insights, here are some links to AWS, Google, Microsoft Azure and other service status dashboards where you can view current and past situations.

Ok, nuff said for now (check out part II here )

Disclosure: I am a customer of AWS for EC2, EBS, S3 and Glacier as well as a customer of Bluehost for hosting and Rackspace for backups. Other than Amazon being a seller of my books (and my blog via Kindle) along with running ads on my sites and being an Amazon Associates member (Google also has ads), none of those mentioned are or have been StorageIO clients.

What do you do when your service provider drops the ball

Do you have a web, internet, backup or other IT cloud service provider of some type?

Do you pay for it, or is it a free service?

Do you take your service provider for granted?

Does your service provider take you or your data for granted?

Does your provider offer some form of service level objectives (SLO)?

For example, Recovery Time Objectives (RTO), Recovery Point Objectives (RPO), Quality of Service (QOS) or if a backup service alternate forms of recovery among others?

So what happens when there is a service disruption, do you threaten to leave the provider and if so, how much does that (or would it) cost you to move?

A couple of weeks ago I was using on a Delta airlines flight from LAX to MSP returning from a west coast speaking engagement event.

During the late evening three hour flight, I was using the gogo inflight wifi service to get caught up on some emails, blog items along with other work items in addition to doing a few twitter tweets while flying high over the real clouds from my virtual office.

During that time, I saw a twitter tweet from Devang Panchigar (@storageNerve) commenting that his hosting service provider Bluehost was down or offline. This caught my attention as Bluehost is also my service provider and a quick check verified that my sites and services were still working. I subsequently sent a tweet to Devang indicating that Bluehost or at least from looking at my sites and services were still functioning, or at least for the time being as I was about to find out. Long story short, about 20 to 25 minutes later, I noticed that I could not longer get to any of my sites, low and behold my Bluehost services were also now offline.

Bluehost

Overall, I have been pleased with Bluehost as a service provider including finding their call support staff very accommodating and easy to work with when I have questions or need something taken care of. Normally I would have simply called Bluehost to see what was going on, however being at about 38,000 feet above the clouds, a quick conversation was not going to be possible. Instead, I checked some forums that revealed Bluehost was experiencing some electrical power issues with their data center (I believe in Utah). Looking at some of the forums as well as various twitter comments, I also decided to check to see if Bluehost CEO Matt Heaton blog was functioning (it was).

It would have been too easy to do one of those irate customer type posts telling them how bad they were, how I was dropping them like a hot potato and then doing a blog post telling everyone to never use them again or along those lines that are far to common and often get deleted as spam.

Instead, I took a different approach (you could have read it here however I just checked and it has been deleted). My comment on Matts blog post took a week or so to be moderated (now since deleted). Essentially my post took the opposite approach of going off on the usual customer tirade instead commenting how ironic that a hosting service for my web site which contains content information about resilient data infrastructure themes was offline.

Now I realize that I am not paying for a high end no downtime always available hosting service, however I also realize that I am paying for a more premium package vs. a basic subscription or even a for free service. While I was not happy about the one hour of downtime around midnight, it was comforting to know that no data was lost and my sites were only offline for a short period of time.

What does all of this mean?

There have been some widely publicized and discussed internet and cloud service related disruptions.

I hope Bluehost continues to improve on their services to stay out of the news for a major disruption as well as minimize or eliminate downtime for their for fee based services.

I also hope that Bluehost CEO Matt Heaton continues to listen to what his customers have to say while improving his services to keep us as customers instead of taking us for granted as some providers or vendors do.

Thanks again to Devang for the tip that there was a service disruption, after all, sometimes we take services for granted and in other situations some service providers take their customers for granted.

Ok, nuff said.

Its US Census time, What about IT Data Centers?

It is that once a decade activity time this year referred to as the US 2010 Census.

With the 2010 census underway, not to mention also time for completing and submitting your income tax returns, if you are in IT, what about measuring, assessing, taking inventory or analyzing your data and data center resources?

US 2010 Cenus formsUS 2010 Cenus forms
Figure 1: IT US 2010 Census forms

Have you recently taken a census of your data, data storage, servers, networks, hardware, software tools, services providers, media, maintenance agreements and licenses not to mention facilities?

Likewise have you figured out what if any taxes in terms of overhead or burden exists in your IT environment or where opportunities to become more optimized and efficient to get an IT resource refund of sorts are possible?

If not, now is a good time to take a census of your IT data center and associated resources in what might also be called an assessment, review, inventory or survey of what you have, how its being used, where and who is using and when along with associated configuration, performance, availability, security, compliance coverage along with costs and energy impact among other items.

Figure 2: IT Data Center Metrics for Planning and Forecasts

How much storage capacity do you have, how is it allocated along with being used?

What about storage performance, are you meeting response time and QoS objectives?

Lets not forget about availability, that is planned and unplanned downtime, how have your systems been behaving?

From an energy or power and cooling standpoint, what is the consumption along with metrics aligned to productivity and effectiveness. These include IOPS per watt, transactions per watt, videos or email along with web clicks or page views per watt, processor GHz per watt along with data movement bandwidth per watt and capacity stored per watt in a given footprint.

Other items to look into for data centers besides storage include servers, data and I/O networks, hardware, software, tools, services and other supplies along with physical facility with metrics such as PUE. Speaking of optimization, how is your environment doing, that is another advantage of doing a data center census.

For those who have completed and sent in your census material along with your 2009 tax returns, congratulations!

For others in the US who have not done so, now would be a good time to get going on those activities.

Likewise, regardless of what country or region you are in, its always a good time to take a census or inventory of your IT resources instead of waiting every ten years to do so.

Ok, nuff said.

How to win approval for upgrades: Link them to business benefits

Drew Rob has another good article over at Processor.com about various tips and strategies on how to gain approval for hardware (or software) purchases with some comments by yours truly.

My tips and advice that are quoted in the story include to link technology resources to business needs impact which may be common sense, however still a time tested effective technique.

Instead of speaking tech talk such as Performance, capacity, availability, IOPS, bandwidth, GHz, frames or packets per second, VMs to PM or dedupe ratio, map them to business speak, that is things that finance, accountants, MBAs or other management personal understand.

For example, how many transactions at a given response time can be supported by a given type of server, storage or networking device.

Or, put a different way, with a given device, how much work can be done and what is the associated monetary or business benefit.

Likewise, if you do not have a capacity plan for servers, storage, I/O and networking along with software and facilities covering performance, availability, capacity and energy demands now is the time to put one in place.

More on capacity and performance planning later, however for now, if you want to learn more, check Chapter 10 (Performance and Capacity Planning) in my book Resilient Storage Networks: Designing Flexible and Scalable Data Infrastructure: Elsevier).

Ok, nuff said.
