What is the best kind of IO? The one you do not have to do

What is the best kind of IO? The one you do not have to do

data infrastructure server storage I/O trends

Updated 2/10/2018

What is the best kind of IO? If no IO (input/output) operation is the best IO, than the second best IO is the one that can be done as close to the application and processor with best locality of reference. Then the third best IO is the one that can be done in less time, or at least cost or impact to the requesting application which means moving further down the memory and storage stack (figure 1).

Storage and IO or I/O locality of reference and storage hirearchy
Figure 1 memory and storage hierarchy

The problem with IO is that they are basic operation to get data into and out of a computer or processor so they are required; however, they also have an impact on performance, response or wait time (latency). IO require CPU or processor time and memory to set up and then process the results as well as IO and networking resources to move data to their destination or retrieve from where stored. While IOs cannot be eliminated, their impact can be greatly improved or optimized by doing fewer of them via caching, grouped reads or writes (pre-fetch, write behind) among other techniques and technologies.

Think of it this way, instead of going on multiple errands, sometimes you can group multiple destinations together making for a shorter, more efficient trip; however, that optimization may also take longer. Hence sometimes it makes sense to go on a couple of quick, short low latency trips vs. one single larger one that takes half a day however accomplishes many things. Of course, how far you have to go on those trips (e.g. locality) makes a difference of how many you can do in a given amount of time.

What is locality of reference?

Locality of reference refers to how close (e.g location) data exists for where it is needed (being referenced) for use. For example, the best locality of reference in a computer would be registers in the processor core, then level 1 (L1), level 2 (L2) or level 3 (L3) onboard cache, followed by dynamic random access memory (DRAM). Then would come memory also known as storage on PCIe cards such as nand flash solid state device (SSD) or accessible via an adapter on a direct attached storage (DAS), SAN or NAS device. In the case of a PCIe nand flash SSD card, even though physically the nand flash SSD is closer to the processor, there is still the overhead of traversing the PCIe bus and associated drivers. To help offset that impact, PCIe cards use DRAM as cache or buffers for data along with Meta or control information to further optimize and improve locality of reference. In other words, help with cache hits, cache use and cache effectiveness vs. simply boosting cache utilization.

What This All Means

What can you do the cut the impact of IO

  • Establish baseline performance and availability metrics for comparison
  • Realize that IOs are a fact of IT virtual, physical and cloud life
  • Understand what is a bad IO along with its impact
  • Identify why an IO is bad, expensive or causing an impact
  • Find and fix the problem, either with software, application or database changes
  • Throw more software caching tools, hyper visors or hardware at the problem
  • Hardware includes faster processors with more DRAM and fast internal busses
  • Leveraging local PCIe flash SSD cards for caching or as targets
  • Utilize storage systems or appliances that have intelligent caching and storage optimization capabilities (performance, availability, capacity).
  • Compare changes and improvements to baseline, quantify improvement

IT Optimization, efficiency, convergence and cloud conversations from SNW

Recently I did a presentation titled backup, restore, BC, DR and archiving (hmm, I think I know of a book with the same title) at the spring 2012 SNW in Dallas. My presentation was on the first morning of the session as I needed to be in Boston to record a video the following Tuesday morning, thus I missed out on the storm clouds and tornadoes that rolled in the next day.

While I was at SNW, had the honor of being a guest on Calvin Zito (aka @HPStorageguy) pod cast that can be found on his Around the Storage Block Blog or by clicking here.

If March 31st is backup day, dont be fooled with restore on April 1st

With March 31st as world backup day, hopefully some will keep recovery and restoration in mind to not be fooled on April 1st.

Lost data

When it comes to protecting data, it may not be a headline news disaster such as earthquake, fire, flood, hurricane or act of man, rather something as simply accidentally overwriting a file, not to mention virus or other more likely to occur problems. Depending upon who you ask, some will say backup or saving data is more important while others will standby that it is recovery or restoration that matter. Without one the other is not practical, they need each other and both need to be done as well as tested to make sure they work.

Just the other day I needed to restore a file that I accidentally overwrote and as luck would have it, my local bad copy had also just overwrote my local backup. However I was able to go and pull an earlier version from my cloud provider which gave a good opportunity to test and try some different things. In the course of testing, I did find some things that have since been updated as well as found some things to optimize for the future.

Destroyed data

My opinion is that if not used properly including ignoring best practices, any form of data storage medium or media as well as software could result or be blamed for data loss. For some people they have lost data as a result of using cloud storage services just as other people have lost data or access to information on other storage mediums and solutions. For example, data has been lost on cloud, tape, Hard Disk Drives (HDDs), Solid State Devices (SSD), Hybrid HDDs (HHDD), RAID and non RAID, local and remote and even optical based storage systems large and small. In some cases, there have been errors or problems with the medium or media, in other cases storage systems have lost access to, or lost data due to hardware, firmware, software, or configuration including due to human error among other issues.

Now is the time to start thinking about modernizing data protection, and that means more than simply swapping out media. Data protection modernization the past several years has been focused on treating the symptoms of downstream problems at the target or destination. This has involved swapping out or moving media around, applying data footprint reduction (DFR) techniques downstream to give near term tactical relief as has been the cause with backup, restore, BC and DR for many years. The focus is starting to expand to how to discuss the source of the problem with is an expanding data footprint upstream or at the source using different data footprint reduction tools and techniques. This also means using different metrics including keeping performance and response time in perspective as part of reduction rates vs. ratios while leveraging different techniques and tools from the data footprint reduction tool box. In other words, its time to stop swapping out media like changing tires that keep going flat on a car, find and fix the problem, change the way data is protected (and when) to cut the impact down stream.

Here is a link to a free download of chapter 5 (Data Protection: Backup/Restore and Business Continuance / Disaster Recovery) from my new book Cloud and Virtual Data Storage Networking (CRC Press).

Do you know HDS or what it means?

How much do you know about HDS?

When you hear HDS in the context of information technology do you think of Hitachi Data Systems?

Along with a bunch of other IT industry advisors, analysts, bloggers, consultants, financiers and pundits or influencers, Im attending a event being sponsored by HDS this week in San Jose California (SJC).

For those not familiar, as a division of the much larger Japan based conglomerate named Hitachi, HDS sells various types of data storage systems and associated management tools along with services.

While on the airplane from Seattle (SEA) to SJC the other night (Disclosure: HDS picked up the one way coach ticket) it occurred to me different things that HDS could refer to besides Hitachi Data Systems.

In addition to being the International Airtranspot Transport Association (IATA) code for Hoedspruit Airport in South Africa where HDS is in the process of buying Shoeden Data Systems (SDS), here are some other possibilities of what HDS could mean.

Hadoop Data Solutions
Half height Disk Shelve
Hardware Disks and Software
Has Dedupe Solutions
Has Disaster recovery Solutions
Has Disk Story
Has Disks Servers
Has Diverse Solutions
Has Done Servers
Have Daily Schnitzel (in Vienna aka Wien)

HDDs Depend on Software
Healthcare Data Systems
Helps Datacenters Save
Helps Data Survives
Helps Data Synchronize
Helps Delete Spam
Helps Dell Servers
Helps Disk Spin
High Density SAS
Houses Data on SSD
How Data Saved
Hu (Yoshida) Discusses Storage
Huge Disk System
HVAC Down Stairs (Heating Ventilation Air Conditioning)
Hybrid Data Systems

Ok, nuff said for now in case the HDS influence folks dont have a sense of influence humor.

The blame game: Does cloud storage result in data loss?

I recently came across a piece by Carl Brooks over at IT Tech News Daily that caught my eye, title was Cloud Storage Often Results in Data Loss. The piece has an effective title (good for search engine: SEO optimization) as it stood out from many others I saw on that particular day.

Industry Trend: Cloud storage

What caught my eye on Carls piece is that it reads as if the facts based on a quick survey point to clouds resulting in data loss, as opposed to being an opinion that some cloud usage can result in data loss.

Data loss

My opinion is that if not used properly including ignoring best practices, any form of data storage medium or media could result or be blamed for data loss. For some people they have lost data as a result of using cloud storage services just as other people have lost data or access to information on other storage mediums and solutions. For example, data has been lost on tape, Hard Disk Drives (HDDs), Solid State Devices (SSD), Hybrid HDDs (HHDD), RAID and non RAID, local and remote and even optical based storage systems large and small. In some cases, there have been errors or problems with the medium or media, in other cases storage systems have lost access to, or lost data due to hardware, firmware, software, or configuration including due to human error among other issues.

Data loss

Technology failure: Not if, rather when and how to decrease impact
Any technology regardless of what it is or who it is from along with its architecture design and implementation can fail. It is not if, rather when and how gracefully along with what safeguards to decrease the impact, in addition to containing or isolating faults differentiates various products or solutions. How they automatically repair and self heal to keep running or support accessibility and maintain data integrity are important as is how those options are used. Granted a failure may not be technology related per say, rather something associated with human intervention, configuration, change management (or lack thereof) along with accidental or intentional activities.

Walking the talk
I have used public cloud storage services for several years including SaaS and AaaS as well as IaaS (See more XaaS here) and knock on wood, have not lost any data yet, loss of access sure, however not data being lost.

I follow my advice and best practices when selecting cloud providers looking for good value, service level agreements (SLAs) and service level objectives (SLOs) over low cost or for free services.

In the several years of using cloud based storage and services there has been some loss of access, however no loss of data. Those service disruptions or loss of access to data and services ranged from a few minutes to a little over an hour. In those scenarios, if I could not have waited for cloud storage to become accessible, I could have accessed a local copy if it were available.

Had a major disruption occurred where it would have been several days before I could gain access to that information, or if it were actually lost, I have a data insurance policy. That data insurance policy is part of my business continuance (BC) and disaster recovery (DR) strategy. My BC and DR strategy is a multi layered approach combining local, offline and offsite as along with online cloud data protection and archiving.

Assuming my cloud storage service could get data back to a given point (RPO) in a given amount of time (RTO), I have some options. One option is to wait for the service or information to become available again assuming a local copy is no longer valid or available. Another option is to start restoration from a master gold copy and then roll forward changes from the cloud services as that information becomes available. In other words, I am using cloud storage as another resource that is for both protecting what is local, as well as complimenting how I locally protect things.

Minimize or cut data loss or loss of access
Anything important should be protected locally and remotely meaning leveraging cloud and a master or gold backup copy.

To cut the cost of protecting information, I also leverage archives, which mean not all data gets protected the same. Important data is protected more often reducing RPO exposure and speed up RTO during restoration. Other data that is not as important is protected, however on a different frequency with other retention cycles, in other words, tiered data protection. By implementing tiered data protection, best practices, and various technologies including data footprint reduction (DFR) such as archive, compression, dedupe in addition to local disk to disk (D2D), disk to disk to cloud (D2D2C), along with routine copies to offline media (removable HDDs or RHDDs) that go offsite,  Im able to stretch my data protection budget further. Not only is my data protection budget stretched further, I have more options to speed up RTO and better detail for recovery and enhanced RPOs.

If you are looking to avoid losing data, or loss of access, it is a simple equation in no particular order:

  • Strategy and design
  • Best practices and processes
  • Various technologies
  • Quality products
  • Robust service delivery
  • Configuration and implementation
  • SLO and SLA management metrics
  • People skill set and knowledge
  • Usage guidelines or terms of service (ToS)

Unfortunately, clouds like other technologies or solutions get a bad reputation or blamed when something goes wrong. Sometimes it is the technology or service that fails, other times it is a combination of errors that resulted in loss of access or lost data. With clouds as has been the case with other storage mediums and systems in the past, when something goes wrong and if it has been hyped, chances are it will become a target for blame or finger pointing vs. determining what went wrong so that it does not occur again. For example cloud storage has been hyped as easy to use, don’t worry, just put your data there, you can get out of the business of managing storage as the cloud will do that magically for you behind the scenes.

The reality is that while cloud storage solutions can offload functions, someone is still responsible for making decisions on its usage and configuration that impact availability. What separates various providers is their ability to design in best practices, isolate and contain faults quickly, have resiliency integrated as part of a solution along with various SLAs aligned to what the service level you are expecting in an easy to use manner.

Does that mean the more you pay the more reliable and resilient a solution should be?
No, not necessarily, as there can still be risks including how the solution is used.

Does that mean low cost or for free solutions have the most risk?
No, not necessarily as it comes down to how you use or design around those options. In other words, while cloud storage services remove or mask complexity, it still comes down to how you are going to use a given service.

Shared responsibility for cloud (and non cloud) storage data protection
Anything important enough that you cannot afford to lose, or have quick access to should be protected in different locations and on various mediums. In other words, balance your risk. Cloud storage service provider toned to take responsibility to meet service expectations for a given SLA and SLOs that you agree to pay for (unless free).

As the customer you have the responsibility of following best practices supplied by the service provider including reading the ToS. Part of the responsibility as a customer or consumer is to understand what are the ToS, SLA and SLOs for a given level of service that you are using. As a customer or consumer, this means doing your homework to be ready as a smart educated buyer or consumer of cloud storage services.

If you are a vendor or value added reseller (VAR), your opportunity is to help customers with the acquisition process to make informed decision. For VARs and solution providers, this can mean up selling customers to a higher level of service by making them aware of the risk and reward benefits as opposed to focus on cost. After all, if a order taker at McDonalds can ask Would you like to super size your order, why cant you as a vendor or solution provider also have a value oriented up sell message.

Poll:  Who is responsible for cloud storage data loss?

Taking action, what you should (or not) do
Dont be scared of clouds, however do your homework, be ready, look before you leap and follow best practices. Look into the service level agreements (SLAs) associated with a given cloud storage product or service. Follow best practices about how you or someone else will protect what data is put into the cloud.

For critical data or information, consider having a copy of that data in the cloud as well as at or in another place, which could be in a different cloud or local or offsite and offline. Keep in mind the theme for critical information and data is not if, rather when so what can be done to decrease the risk or impact of something happening, in other words, be ready.

Data put into the cloud can be lost, or, loss of access to it can occur for some amount of time just as happens with using non cloud storage such as tape, disk or ssd. What impacts or minimizes your risk of using traditional local or remote as well as cloud storage are the best practices, how configured, protected, secured and managed. Another consideration is the type and quality of the storage product or cloud service can have a big impact. Sure, a quality product or service can fail; however, you can also design and configure to decrease those impacts.

Wrap up
Bottom line, do not be scared of cloud storage, however be ready, do your homework, review best practices, understand benefits and caveats, risk and reward. For those who want to learn more about cloud storage (public, private and hybrid) along with data protection, data management, data footprint reduction among other related topics and best practices, I happen to know of some good resources. Those resources in addition to the links provided above are titled Cloud and Virtual Data Storage Networking (CRC Press) that you can learn more about here as well as find at Amazon among other venues. Also, check out Enterprise Systems Backup and Recovery: A Corporate Insurance Policy by Preston De Guise (aka twitter @backupbear ) which is a great resource for protecting data.

Ok, nuff said for now

Practical Email optimization and archiving strategies

Email is a popular tool for messaging, calendaring, and managing contacts along with attachments in most organizations.

Email and messaging

Given the popularity of email and diverse ways that it is used for managing various forms of unstructured data attachments including photos, video, audio, spreadsheets, presentations and other document objects, there are corresponding back end challenges. Those back end challenges including managing the data storage repositories (e.g. file systems and storage systems) that are used for preserving and serving email documents along with enabling regulatory or compliance mandates.

Email archiving is an important enabler for regulatory compliance and e-discovery functions. However there is another important use for E-mail archiving which as a data footprint reduction (DFR) technique and technology enables storage optimization, being green and supporting growth while stretching budgets further. There is after all no such thing as a data or information recession and all one has to do to verify the trend is to look at your own email activity.

Industry Trend: Data growth and demand

There are however constraints on time, budgets and demands to do more while relying on more information and email has become a central tool for messaging including social media networking, handling of attachments and means to manage all of that data.

DFR enables more data to be stored, retained, managed and maintenance in a cost effective manner. This includes storing more data managed per person, where when the additional data being retained adds value to an organization. Also included is keeping more data readily accessible, not necessarily instantly accessible, however but within minutes instead of hours or days depending on service requirements.

Data footprint reduction (DFR) techniques and technologies

Here is a link to a recent article that I did presenting five tips and strategies for optimizing e-mail using archiving.

Hopefully many of you will find these to be common sense tips being implemented, however if not, now is the time to take action to stretch your resources further to do more.

In general email optimization tips include:

  • Set policies for retention and disposal
  • Establish filters and rules
  • Index and organize your inbox
  • Archive messages regularly
  • Perform routine cleanup and optimization
  • Leverage cloud data protection services and solutions

When it comes to archiving projects, walk before you run, establish success to build upon for broader deployment of E-mail archiving by finding and address low hanging fruit opportunities.

Instead of trying to do to much, find opportunities that can be addressed and leveraged as examples to build business cases to move forward.

By having some success stories and proof points, these can be used to help convince management to support additional steps not to mention getting them to back your polices to achieve success.

An effective way to convince management these days is to show them how by taking additional Email archiving steps you can support increased growth demand, reduce costs while enhancing productivity not to mention adding compliance and ediscovery capabilities as side benefits.

You can read more here and here, ok, nuff said for now.

Whats inside the book, theme and topics covered

When it comes to clouds, virtualization, converged and dynamic infrastructures Dont be scared however do look before you leap to be be prepared including doing your homework.

What this means is that you should do your homework, prepare, learn, and get involved with proof of concepts (POCs) and training to build the momentum and success to continue an ongoing IT journey. Identify where clouds, virtualization and data storage networking technologies and techniques compliment and enable your journey to efficient, effective and productive optimized IT services delivery.

 

There is no such thing as a data or information recession: Do more with what you have

A common challenge in many organizations is exploding data growth along with associated management tasks and constraints, including budgets, staffing, time, physical facilities, floor space, and power and cooling. IT clouds and dynamic infrastructure environments enable flexible, efficient and optimized, cost-effective and productive services delivery. The amount of data being generated, processed, and stored continues to grow, a trend that does not appear to be changing in the future. Even during the recent economic crisis, there has been no slow down or information recession. Instead, the need to process, move, and store data has only increased, in fact both people and data are living longer. CVDSN presents options, technologies, best practices and strategies for enabling IT organizations looking to do more with what they have while supporting growth along with new services without compromising on cost or QoS delivery (see figure below).

Driving Return on Innovation the new ROI: Doing more, reducing costs while boosting productivity

 

Expanding focus from efficiency and optimization to effectiveness and productivity

A primary tenant of a cloud and virtualized environment is to support growing demand in a cost-effective manner  with increased agility without compromising QoS. By removing complexity and enabling agility, information services can be delivered in a timely manner to meet changing business needs.

 

There are many types of information services delivery model options

Various types of information services delivery modes should be combined to meet various needs and requirements. These complimentary service delivery options and descriptive terms include cloud, virtual and data storage network enabled environments. These include dynamic Infrastructure, Public & Private and Hybrid Cloud, abstracted, multi-tenant, capacity on demand, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) among others.

Convergence combing different technology domains and skill sets

Components of a cloud and virtual environment include desktop, servers, and storage, networking, hardware, and software, services along with APIs and software stacks. This include virtual and physical desktops, data, voice and storage networks, LANs, SANs, MANs, WANs, faster blade and rack servers with more memory, SSD and high-capacity storage and associated virtualization tools and management software. True convergence combines leveraging technology and people, processes and best practices aligned to make the most of those resources to deliver cost-effective services delivery.

 

Best people, processes, practices and products (the four Ps)

Bringing all the various components together is the Ps (people skill sets, process, practices and products). This means leveraging and enhancing people skill sets and experience, process and procedures to optimize workflow for streamlined service orchestration, practices and policies to be more effectively reducing waste without causing new bottlenecks, and products such as racks, stacks, hardware, software, and managed or cloud services.

 

Service categories and catalogs, templates SLO and SLA alignment

Establishing service categories aligned to known service levels and costs enables resources to be aligned to applicable SLO and SLA requirements. Leveraging service templates and defined policies can enable automation and rapid provisioning of resources including self-service requests.

 

Navigating to effective IT services delivery: Metrics, measurements and E2E management

You cannot effectively manage what you do not know about; likewise, without situational awareness or navigation tools, you are flying blind. E2E (End to End) tools can provide monitoring and usage metrics for reporting and accounting, including enabling comparison with other environments. Metrics include customer service satisfaction, SLO and SLAs, QoS, performance, availability and costs to service delivered.

 

The importance of data protection for virtual, cloud and physical environments

Clouds and virtualization are important tools and technologies for protecting existing consolidated or converged as well as traditional environments. Likewise, virtual and cloud environments or data placed there also need to be protected. Now is the time to rethink and modernize your data protection strategy to be more effective, protecting, preserving and serving more data for longer periods of time with less complexity and cost.

 

Packing smart and effectively for your journey: Data footprint reduction (DFR)

Reducing your data footprint impact leveraging data footprint reduction (DFR) techniques, technologies and best practices is important for enabling an optimized, efficient and effective IT services delivery environment. Reducing your data footprint is enabled with clouds and virtualization providing a means and mechanism for archiving inactive data and for transparently moving it. On the other hand, moving to a cloud and virtualized environment to do more with what you have is enhanced by reducing the impact of your data footprint. The ABCDs of data footprint reduction include Archiving, Backup modernization, Compression and consolidation, Data management and dedupe along with Storage tiering and thin provisioning among other techniques.

Are Hard Disk Drives (HDDs) getting too big?

Lets start out by clarifying something, that is in terms of context or scope, big means storage capacity as opposed to the physical packaging size of a hard disk drive (HDD) which are getting smaller.

So are HDDs in terms of storage capacity getting too big?

This question of if HDDs storage capacity getting too big to manage comes up every few years and it is the topic of Rick Vanovers (aka twitter @RickVanover Episode 27 Pod cast: Are hard drives getting to big?

Veeam community podcast guest appearance

As I discuss in this pod cast with Rick Vannover of Veeam, with the 2TB and even larger future 4TB, 8 to 9TB, 18TB, 36TB and 48 to 50TB drives not many years away, sure they are getting bigger (in terms of capacity) however we have been here before (or at least some of us have). We discuss how back in the late 90s HDDs were going from 5.25 inch to 3.5 inch (now they are going from 3.5 inch to 2.5 inch), and 9GB were big and seen as a scary proposition by some for doing RAID rebuilds, drive copy or backups among other things, not to mention if putting to many eggs (or data) in one basket.

In some instances vendors have been able to combine various technologies, algorithms and other techniques to RAID rebuild a 1TB or 2TB drive in the same or less amount of time as it used to take to process a 9GB HDD. However those improvements are not enough and more will be needed leveraging faster processors, IO busses and back planes, HDDs with more intelligence and performance, different algorithms and design best practices among other techniques that I discussed with Rick. After all, there is no such thing as a data recession with more information to be generated, processed, moved, stored, preserved and served in the future.

If you are interested in data storage, check out Ricks pod cast and hear some of our other discussion points including how SSD will help keep the HDD alive similar to how HDDs are offloading tape from their traditional backup role, each with its changing or expanding focus among other things.

On a related note, here is post about RAID remaining relevant yet continuing to evolve. We also talk about Hybrid Hard Disk Drives (HHDD) where in a single sealed HDD device there is flash and dram along with a spinning disk all managed by the drives internal processor with no external special software or hardware needed.

Listen to comments by Greg Schulz of StorageIO on HDD, HHDD, SSD, RAID and more

Put on your head phones (or not) and check out Ricks pod cast here (or on the head phone image above).

Thanks again Rick, really enjoyed being a guest on your show.

Whats your take, are HDDs getting to big in terms of capacity or do we need to leverage other tools, technology and techniques to be more effective in managing expanding data footprint including use of data footprint reduction (DFR) techniques?

Ok, nuff said for now.
