Modernizing data protection with certainty

Speaking of and about modernizing data protection, back in June I was invited to be a keynote presenter on industry trends and perspectives at a series of five dinner events (Boston, Chicago, Palo Alto, Houston and New York City) sponsored by Quantum (that is a disclosure btw).

backup, restore, BC, DR and archiving

The theme of the dinner events was an engaging discussion around modernizing data protection with certainty along with clouds, virtualization and related topics. Quantum and one of their business partner resellers started the event with introductions followed by an interactive discussion by myself, followed by David Chappa (@davidchapa ) who ties the various themes with what Quantum is doing along with some of their customer success stories.

Themes and examples for these events build on my book Cloud and Virtual Data Storage Networking including:

  • Rethinking how, when, where and why data is being protected
  • Big data, little data and big backup issues and techniques
  • Archive, backup modernization, compression, dedupe and storage tiering
  • Service level agreements (SLA) and service level objectives (SLO)
  • Recovery time objective (RTO) and recovery point objective (RPO)
  • Service alignment and balancing needs vs. wants, cost vs. risk
  • Protecting virtual, cloud and physical environments
  • Stretching your available budget to do more without compromise
  • People, processes, products and procedures

Quantum is among other industry leaders with multiple technology and solution offerings for addressing different aspects of data footprint reduction and data protection modernization. These include for physical, virtual and cloud environments along with traditional tape, disk based, compression, dedupe, archive, big data, hardware, software and management tools. A diverse group of attendees have been at the different events including enterprise and SMB, public, private and government across different sectors.

Following are links to some blog posts that covered first series of events along with some of the specific themes and discussion points from different cities:

Via ITKE: The New Realities of Data Protection
Via ITKE: Looking For Certainty In The Cloud
Via ITKE: Success Stories in Data Protection: Cloud virtualization
Via ITKE: Practical Solutions for Data Protection Challenges
Via David Chappas blog

If you missed attending any of the above events, more dates are being added in August and September including stops in Cleveland, Raleigh, Atlanta, Washington DC, San Diego, Connecticut and Philadelphia with more details here.

Ok, nuff said for now, hope to see you at one of the upcoming events.

Cheers

How can direct attached storage (DAS) make a comeback if it never left?

Server and StorageIO industry trend and perspective DAS

Have you seen or heard the theme that Direct Attached Storage (DAS), either dedicated or shared, internal or external is making a comeback?

Wait, if something did not go away, how can it make a comeback?

IMHO it is as simple as for the past decade or so, DAS has been overshadowed by shared networked storage including switched SAS, iSCSI, Fibre Channel (FC) and FC over Ethernet (FCoE) based block storage area networks (SAN) and file based (NFS and Windows SMB/CIFS) network attached storage (NAS) using IP and Ethernet networks. This has been particularly true by most of the independent storage vendors who have become focused on networked storage (SAN or NAS) solutions.

However some of the server vendors have also jumped into the deep end of the storage pool with their enthusiasm for networked storage, even though they still sell a lot of DAS including internal dedicated, along with external dedicated and shared storage.

Server and StorageIO industry trend and perspective DAS

The trend for DAS storage has evolved with the interfaces and storage mediums including from parallel SCSI and IDE to SATA and more recently 3Gbs and 6Gbs SAS (with 12Gbs in first lab trials). Similarly the storage mediums include a mix of fast 10K and 15K hard disk drives (HDD) along with high-capacity HDDs and ultra-high performance solid state devices (SSD) moving from 3.5 to 2.5 inch form factors.

While there has been a lot of industry and vendor marketing efforts around networked storage (e.g. SAN and NAS), DAS based storage was over shadowed so it should not be a surprise that those focused on SAN and NAS are surprised to hear DAS is alive and well. Not only is DAS alive and well, it’s also becoming an important scaling and convergence topic for adding extra storage to appliances as well as servers including those for scale out, big data, cloud and high density not to mention high performance and high productivity computing.

Server and StorageIO industry trend and perspective DAS

Consequently its becoming ok to talk about DAS again. Granted you might get some peer pressure from your trend setting or trend following friends to get back on the networked storage bandwagon. Keep this in mind, take a look at some of the cool trend setting big data and little data (database) appliances, backup, dedupe and archive appliances, cloud and scale out NAS and object storage systems among others and will likely find DAS on the back-end. On a smaller scale, or in high-density rack deployments in large cloud or similar environments you may also find DAS including switched shared SAS.

Does that mean SANs are dead?
No, not IMHO despite what some vendors marketers and their followers will claim which is ironic given how some of them were leading the DAS is dead campaign in favor of iSCSI or FC or NAS a few years ago. However simply comparing DAS to SAN or NAS in a competing way is like comparing apples to oranges, instead, look at how and where they can complement and enable each other. In other words, different tools for various tasks, various storage and interfaces for different needs.

Thus IMHO DAS never left or went anywhere per say, it just was not fashionable or cool to talk about until now as it is cool and trend to discuss it again.

Ok, nuff said for now.

Dell is buying Quest software, not the phone company Qwest

Dell Storage Customer Advisory Panel (CAP)

For those not familiar with Quest, they are a software company not to be confused with the telephone communications company formerly known as Qwest (aka now known as centurylink).

Both Dell and Quest have been on software related acquisition initiatives that past few years with Quest having purchased vKernel, Vizoncore (vRanger virtualization backup), BakBone (who had acquire Alavarii and Asempra) for traditional backup and data protection among others. Not to be out done, as well as purchasing Quest, Dell has also more recently bought Appassure (Disclosure: StorageIOblog site sponsor) for data protection, Sonicwall and Wyse in addition to some other recent purchases (ASAP, Boomi, Compellent, Exanet, EqualLogic, Force10, InsightOne, KACE, Ocarina, Perot, RNA and Scalent among others).

What does this mean?
Dell is expanding the scope of their business with more products (hardware, software), solution bundles, services and channel partnering opportunities Some of the software tools and focus areas that Quest brings to the Dell table or portfolio include:

Database management (Oracle, SQLserver)
Data protection (virtual and physical backup, replication, bc, dr)
Performance monitoring (DCIM and IRM) of applications and infrastructure
User workspace management (application delivery)
Windows server management (migrate and manage, AD, exchange, sharepoint)
Identify and access management (security, compliance, privacy)

What does Dell get by spending over $2B USD on quest?

  • Additional software titles or product
  • More software developers for their Software group
  • Sales people to help promote, partner and sell software solutions
  • Create demand pull for other Dell products and services via software
  • Increase its partner reach via existing Quest VARs and business partners
  • Extend the size of the Dell software and intellectual property (IP) portfolio
  • New revenue streams that compliment existing products and lines of business
  • Potential for better rate of return on some of its $12B USD in cash or equivalence

    Is this a good move for Dell?
    Yes for the above reasons

    • Is there a warning to this for Dell?
    Yes, they need to execute, keep the Quest team focused along with their other teams on the respective partners, products and market opportunities while expanding into new areas. Dell needs to also leverage Quest to further its cause in creating trust, confidence and strategic relationships with channel partners to reach new markets in different geographies. In addition, Dell needs to articulate its strategy and positioning of the various solutions to avoid products being perceived as competing vs. complimenting each other.

    Green IT deferral blamed on economic recession might be result of green gap

    Storage I/O Industry Trends and Perspectives

    I recently saw a comment somewhere that talked about Green IT being deferred or set aside due to lack of funding because of ongoing global economic turmoil. For those who see Green IT in the context of the green washing efforts that requiring spending to gain some benefits that I can understand. After all, if your goal is to simply go and be or be seen as being green, there is a cost to doing that.

    With tight or shrinking IT budgets, there are other realities and while organizations may want to do the right thing helping the environment, however that is often seen as overhead to financial conscious management.

    On the other hand, turn the green washing messaging off or at least dial-it back a bit as has been the case the past couple of years.

    Expand the Green IT discussion or change it around a bit from that of being seen or perceived as being green by energy efficiency or avoidance to that of effectiveness, enhanced productivity, doing more with what you have or with less and there is a different opportunity.

    That opportunity is to meet the financial and business goals or requirements that as a by-product help the environment. In other words, expand the focus of Green IT to that of economics and improving on resource effectiveness and the environment gets a free ride, or, Green gets self-funded.

    The Green and Virtual Data Center Book addressing optimization, effectivness, productivity and economics

    The challenge is what I refer to as the Green Gap, which is the disconnect between what is talked about (e.g. messaging) and thus perceived to be Green IT and where common IT opportunities exist (or missed opportunities have occurred).

    Green IT or at least the tenants of driving efficiency and effectiveness to use energy more effectively, address recycling and waste, removable of hazardous substance and other items continues to thrive. However, the green washing is subsiding and overtime organizations will not be as dismissive of Green IT in the context of improving productivity, reducing complexity and costs, optimization and related themes tied to economics where the environment gets a free ride.

    Why FC and FCoE vendors get beat up over bandwidth?

    Storage I/O Industry Trends and Perspectives

    Have you noticed how Fibre Channel (FC) and FC over Ethernet (FCoE) switch and adapter vendors and their followers focus around bandwidth vs. response time, latency or other performance activity? For example, 8Gb FC (e.g. 8GFC), or 10Gb as opposed to latency and response time, or IOPS and other activity indicators.

    When you look at your own environment, or that of a customers or prospects or hear of a conversation involving storage networks, is the focus on bandwidth, or lack of it, or perhaps throughput being a non-issue? For example, a customer says why go to 16GFC when they are barely using 8Gb with their current FC environment.

    This is not a new phenomenon and is something I saw when working for a storage-networking vendor who had SAN, MAN and WAN solutions (E.g. INRANGE). Those with networking backgrounds tended to focus on bandwidth when discussing storage networks while those with storage, server or applications background also look at latency or IO completion time (response time), queuing, message size, IOPs or frames and packets per second. Thus there are different storage and networking metrics that matter that are also discussed further in my first book Resilient Storage Networks: Designing Flexible Scalable Data Infrastructures.

    When I hear a storage networking vendor talk about their latest 16GFC based product I like to ask them what is the biggest benefit vs. 8GFC and not surprisingly, the usual response is like twice the bandwidth. When I ask them about what that means in terms of more IOPS in a given amount of time, or reduced IO completion time, lower latency, sometimes I often get the response along the lines of Yeah, that too, however it has twice the bandwidth.

    Ok, I get it, yes, bandwidth is important for some applications, however so too are activity measured in IOPS, transactions, packets, frames, pages, sequences and exchanges among other units of measure along with response time and latency (e.g. different storage and networking metrics that matter).

    What many storage networking vendors actually get, however they don’t talk about it for various reasons, perhaps because they are not be asked about it, or engaged in the conversation is that there is an improvement in response time in going from such as 8GFC to 16GFC. Likewise, there can be improvements in response time in addition to the more commonly discussed bandwidth.

    If you are a storage networking switch, adapter or other component vendor, var or channel partner expand your conversation to include activity and response time as part of your value proposition. Likewise, if you are a customer, ask your technology providers to expand on the conversation of how new technologies help in areas other than bandwidth.

    Only you can prevent cloud data loss

    Storage I/O trends

    Some of you might remember the saying from Smokey the bear, only you can prevent forest fires and for those who do not know about that, click on the image below.

    The reason I bring this up is that while cloud providers are responsible (see the cloud blame game) is that it is also up to the user or consumer to take some ownership and responsibility.

    Similar to vendor lock-in, the only one who can allow vendor lock in is the customer, granted a vendor can help influence the customer.

    The same theme applies to public clouds and cloud storage providers in that there is responsibility of providers along with government and industry regulations to help protect consumers or users. However, there is also the shared responsibility of the user and consumer to make informed decisions.

    What is your perspective on who is responsible for cloud data protection?

    Are large storage arrays dead at the hands of SSD?

    Storage I/O trends

    An industry trends and perspective.

    .

    Are large storage arrays dead at the hands of SSD? Short answer NO not yet.
    There is still a place for traditional storage arrays or appliances particular those with extensive features, functionality and reliability availability serviceability (RAS). In other words, there is still a place for large (and small) storage arrays or appliances including those with SSDs.

    Is there a place for newer flash SSD storage systems, appliances and architectures? Yes
    Similar to how there is a place for traditional midrange storage arrays or appliances have found their roles vs. traditional higher end so-called enterprise arrays. Think as an example  EMC CLARiiON/VNX or HP EVA/P6000 or HDS AMS/HUS or NetApp FAS or IBM DS5000 or IBM V7000 among others vs. EMC Symmetrix/DMX/VMAX or HP P10000/3Par or HDS VSP/USP or IBM DS8000. In addition to traditional enterprise or high-end storage systems and midrange also known as modular, there are also specialized appliances or targets such as for backup/restore and archiving. Also do not forget the IO performance SSD appliances like those from TMS among others that have been around for a while.

    Is the role of large storage systems changing or evolving? Yes
    Given their scale and ability to do large amounts of work in a dense footprint, for some the role of these systems is still mission critical tier 1 application and data support. For other environments, their role continues to evolve being used for high-density tier 2 bulk or even near-line storage for on-line access at scale.

    Storage I/O trends

    Does this mean there is completion between the old and new systems? Yes
    In some circumstances as we have seen already with SSD solutions. Some will place as competing or replacements while others as complementing. For example in the PCIe flash SSD card segment EMC VFCache is positioned is complementing Dell, EMC, HDS, HP, IBM, NetApp, Oracle or others storage vs. FusionIO who positions as a replacement for the above and others. Another scenario is how some SSD vendors have and continue to position their all-flash SSD arrays using either drives or PCIe cards to complement and coexist with other storage systems in an environment (e.g. data center level tiering) vs. as a replacement. Also keep in mind SSD solutions that also support a mix of flash devices and traditional HDDs for capacity and cost savings or cloud access in the same solution.

    Does this mean that the industry has adopted all SSD appliances as the state of art?
    Avoid confusing industry adoption or talk with industry and customer deployment. They are similar, however one is focused on what the industry talks about or discusses as state of art or the future while the other is what customers are doing. Certainly some of the new flash SSD appliance and storage startups such as Solidfire, Nexgen, Violin, Whiptail or veteran TMS among others have promising futures, some of which may actually be in play with the current SSD market shakeout and consolidation.

    Does that mean everybody is going SSD?
    SSD customer adoption and deployment continues to grow, however so too does the deployment of high-capacity HDDs.

    Storage I/O trends

    Do SSDs need HDDs, do HDDs need SSDs? Yes
    Granted there are environments where needs can be addressed by all of one or the other. However at least near term, there is a very strong market for tiering and mix of SSD, some fast HDDs and lots of high-capacity HDDs to meet various needs including performance, availability, capacity, energy and economics. After all, there is no such thing, as a data or information recession yet budgets are tight or being reduced. Likewise, people and data are living longer.

    What does this mean?
    If there, were no such thing as a data recession and budgets a non-issue, perhaps everything could move to all flash SSD storage systems. However, we also know that people and data are living longer along with changing data life-cycle patterns. There is also the need for performance to close the traditional data center IO performance to space capacity gap and bottlenecks as well as store and keep data longer.

    There will continue to be a need for a mix of high-capacity and high performance. More IO will continue to gravitate towards the IO appliances, however more data will settle in for longer-term retention and continued access as data life-cycle continue to evolve. Watch for more SSD and cache in the large systems, along with higher density SAS-NL (SAS Near Line e.g. high capacity) type drives appearing in those systems.

    If you like new shiny new toys or technology (SNTs) to buy, sell or talk about, there will be plenty of those to continue industry adoption while for those who are focused on industry deployment, there will be a mix of new, and continued evolution for implementation.

    Is SSD dead? No, however some vendors might be

    Storage I/O trends

    Is SSD dead? No, however some vendors might be

    In a recent conversation with Dave Raffo about the nand flash solid state disk (SSD) market, we talked about industry trends, perspectives and where the market is now as well as headed. One of my comments is, has been and will remain that the industry has still not reached anywhere near full potential for deployment of SSD for enterprise, SMB and other data storage needs. Granted, there is broad adoption in terms of discussion or conversation and plenty of early adopters.

    SSD and in particular nand flash is anything but dead, in fact in the big broad picture of things, it is still very early in the game. Sure, for those who cover and crave the newest, latest and greatest technology to talk about, nand flash SSD might seem old, yesterday news, long in the tooth and time for something else. However, for those who are focused on deployment vs. adoption such as customers, in general, nand flash SSD in its many packaging options has still not yet reached its full potential.

    Despite the hype, fanfare from CEOs or their evangelist along with loyal followers of startups that help drive industry adoption (e.g. what is talked about), there is still lots of upside growth in the customer drive industry deployment (actually buying, installing and using) for nand flash SSD.

    What about broad customer deployments?

    Sure, there are the marquee customer success stories that you need a high-capacity SAS or SATA drive to hold the YouTube videos, slide decks, press releases for.

    However, have we truly, reached broad customer deployment or broad industry adoption?

    Hence, I see more startups coming into the market space, and some exiting on their own, via mergers and acquisition or other means.

    Will we see a feeding frenzy or IPO craze as with earlier hype cycles of technologies, IMHO there will be some companies that get the big deal, some will survive as new players running as a business vs. running to be acquired or IPO. Others will survive by evolving into something else while others will join the where are they now list.

    If you are a SSD startup, CEO, CxO, or marketer, their PR, evangelist or loyal follower do not worry as the SSD market and even nand flash is far from being dead. On the other hand, if you think that it has hit its full stride, you are missing either the bigger picture, or too busy patting yourselves on the back for a job well done. There is much more opportunity out there and not even all the low hanging fruit has been picked yet.

    More storage and IO metrics that matter

    It is great to see more conversations and coverage around storage metrics that matter beyond simply focusing on cost per GByte or TByte (e.g. space capacity). Likewise, it is also good to see conversations expanding beyond data footprint reduction (DFR) from a space capacity savings or reduction ratio to also address data movement and transfer rates. Also good to see is increase in discussion around input/output operations per section (IOPs) tying into conversations from virtualization, VDI, cloud to Sold State Devices (SSD).

    Other storage and IO metrics that matter include latency or response time, which is how fast work is done, or time spent. Latency also ties to IOPS in that as more work arrives to be done (IOPS) of various size, random or sequential, reads or writes, queue depths are an indicator of how well work is flowing. Another storage and IO metric that matters is availability because without it, performance or capacity can be affected. Likewise, without performance, availability can be affected.

    Needless to say that I am just scratching the surface here with storage and IO metrics that matter for physical, virtual and cloud environments from servers to networks to storage.

    Here is a link to a post I did called IO, IO, it is off to storage and IO metrics we go that ties in themes of performance measurements and solid-state disk (SSD) among others. Also check out this piece about why VASA (VMware storage analysis metrics) is important to have your VMware CASA along with Windows boot storage and IO performance for VDI and traditional planning purposes.

    Check out this post about metrics and measurements that matter along with this conversation about IOPs, capacity, bandwidth and purchasing discussion topics.

    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
