Updated 1/21/2018

Welcome to the Cloud, Big Data, Software Defined, scale-out, Bulk and Object Storage Fundamentals page.

This page contains various resources, tips, essential topics pertaining to Software Defined, scale-out, Cloud, Bulk and Object Storage Fundamentals. Other resources pertaining to Software Defined, scale-out, Cloud, Bulk and Object Storage include:

  • www.objectstoragecenter.com
  • Software Defined Data Infrastructure Essentials book (CRC Press)
  • Cloud, Software Defined, Scale-Out, Object Storage News Trends

    • There are various types of cloud, bulk and object storage including public services such as Amazon Web Services (AWS) Simple Storage Service (S3), Google, Microsoft Microsoft Azure, IBM Softlayer, Rackspace among many others. There are also solutions for hybrid and private deployment from Cisco, Cloudian, Fujifilm, DDN, Dell EMC, Fujitsu, HDS, HPE, IBM, NetApp, Noobaa, OpenStack, Quantum, Rackspace, Scality, Seagate, Spectra, Storpool, Suse, Swift and WD among others.

    Cloud products and services among others, along with associated data infrastructures including object storage, file systems, repositories and access methods are at the center of bulk, big data, big bandwidth and little data initiatives on a public, private, hybrid and community basis. After all, not everything is the same in cloud, virtual and traditional data centers or information factories from active data to in-active deep digital archiving.

    Cloud Object Storage Fundamentals Access and Architectures

    There are many facets to object storage including technology implementation, products, services, access and architectures for various applications and use scenarios.

    • Project or Account – Top of the hierarchy that can represent the owner or billing information for a service that where buckets are also attached.
    • Region – Location where data is stored that can include one or more data centers also known as Availability Zones.

      • AWS S3 Cross region replication
      Moving and Replicating Buckets/Containers, Subfolders and Objects

    • Availability Zone (AZ) or data center or server that implement durability and accessibility for availability within a region.

      • AWS Regions and Availability Zones AZs
      Example of Regions and Availability Zones (AZs)

    • Bucket or Container – Where objects or sub-folders containing objects are attached and accessed.

      • Object storage fundamentals sddc and cloud software defined

    • Sub-folder – While object storage can be located in a flat namespace for commonality and organization some solutions and service support the notion of sub-folder that resemble traditional directory hierarchy.
    • Object – Byte (or bit) stream that can be as small as one byte to as large as several Tbytes (some solutions and services support up to 5TByte sized objects). The object contains whatever data in any organization along with metadata. Different solutions and services support from a couple hundred KBytes of meta-data to Mbytes worth of meta-data. Regarding what can be stored in an object, anything from files, videos, images, virtual disks (VMDKs, VHDX), ZIP or tar files, backup and archive save sets, executable images or ISO’s, anything you want.
    • End-point – Where or what your software, application or tool and utilities along with gateways attach to for accessing buckets and objects.

      • object storage fundamentals, sddc and cloud storage example

      A common theme for object storage is flexibility, along with scaling (performance, availability, capacity, economics) along with extensibility without compromise or complexity. From those basics, there are many themes and variations from how data is protected (RAID or no RAID, hardware or software), deployed as a service or as tin wrapped software (an appliance), optimized for archiving or video serving or other applications.

      Many facets of cloud and object storage access

      One aspect of object and cloud storage is accessing or using object methods including application programming interfaces (API’s) vs. traditional block (LUN) or NAS (file) based approaches. Keep in mind that many object storage systems, software, and services support NAS file-based access including NFS, CIFS, HDFS  among others for compatibility and ease of use.

      Likewise various API’s can be found across different object solutions, software or services including Amazon Web Services (AWS) Simple Storage Service (S3) HTTP REST based, among others. Other API’s will vary by specific vendor or product however can include IOS (e.g. Apple iPhone and iPad), WebDav, FTP, JSON, XML, XAM, CDMI, SOAP, and DICOM among others. Another aspect of object and cloud storage are expanded  and dynamic metadata.

      While traditional file systems and NAS have simple or fixed metadata, object and cloud storage systems, services and solutions along with some scale-out file systems have ability to support user defined metadata. Specific systems, solutions, software, and services will vary on the amount of metadata that could range on the low-end from 100s of KBytes  to tens or more Mbytes.

    EMCworld 2016 Getting Started on Dell EMC announcements

    EMCworld 2016 Getting Started on Dell EMC announcements

    server storage I/O trends

    It’s the first morning of EMCworld 2016 here in Las Vegas with some items already announced today, and more in the wings. One of the underlying themes and discussions besides what’s new or who’s doing what, is that this is for all practical purpose the last EMCworld with the upcoming Dell acquisition. What’s not clear is will there be a renamed and repackaged Dell/EMCworld?

    With current EMC President Jeremy Burton who used to be the Chief Marketing Officer (CMO) at EMC slated to become the CMO across all of Dell, my bet is that there will be some type of new event picking up and moving to a new level of where EMCworld and Dellworld have been. More on the future of EMC and Dell in future posts, however for now, lets see what has unfolded so far today.

    Today’s EMCworld theme is modernize the data center which means a mix of hardware, software and services announcements spanning physical, virtual, cloud among others (e.g. how do you want your servers, storage and data infrastructure wrapped). While the themes are still EMC as the Dell acquisition has yet to be completed, however there is a Dell presence, including Michael Dell here in person (more on Dell later).

    The first wave of announcements include:

    • Unity All Flash Array (AFA) for small, entry-level environments
    • EMC Enterprise Copy Data Management software tools portfolio
    • ViPR Version 3.0 Controller
    • Virtustream global hyper-scale Storage Cloud for data protection and cloud native object
    • MyService360

    • Datadomain virtual edition and long-term archive

    What About The Dell Deal

    Michael Dell who is here at EMCworld announced on the main stage that Dell Technologies will be the name of the families of business.

    This family of business includes the joint Dell, EMC, VMware, Pivotal, Secureworks, RSA and Virtustream. The Dell client focused business will be called Dell leveraging

    that Brand, while the new joint Dell and EMC enterprise business will be called Dell EMC leveraging both of those brands. As a reminder, the Dell servers business unit will be moving into the existing EMC business as part of the enterprise business unit.

    Lets move onto the technology announcements from today.

    Unity AFA (and Hybrid)

    The new Unity all flash array (AFA) is a dual controller storage system optimized for Nonvolatile Memory (NVM) flash SSD, with unified (block and file) access. EMC is positioning Unity as an entry-level AFA starting around $18K USD for a 2U solutions (much capacity that includes is not yet known, more on that in a future post). As well as having a low entry cost, EMC is positioning Unity for a broad, mass market, volume distribution that can be leveraged by their partners, including Dell. More on Unity in future posts. While Unity is new and modern, it comes from the same group who has created the VNXe leveraging that knowledge and skills base.

    Note that Unity is positioned for small, mid-sized, remote office branch office (ROBO), departmental and specialized AFA situations, where EMC NVMe based DSSD D5 is positioned for higher-end shared direct attached server flash, while XtremIO and VMAX also positioned for higher-end, higher performance and workload consolidation scenarios.

    • Simple, flexible, easy to use in a 2U packaging that scale up to 80TB of NVM flash SSD storage
    • Scalable up to 3PB of storage for larger expanded configurations
    • Affordable ($18K USD starting price, $10K entry-level hybrid)
    • Modern AFA storage for entry, small, mid-sized, workgroup, departments and specialized environments
    • Unified file, block, and VMware VVOL support for storage access
    • Also available in hybrid, as well as software defined virtual and converged configurations
    • Higher performance (EMC indicates 300,000 IOPs) for given entry-level systems
    • Available in all-flash array, hybrid array, software-defined and converged configurations
    • Native controller based encryption with synchronous and asynchronous replication
    • VMware VASA 2.0, VAAI, VVols and VMware integration
    • Tight integration with EMC Data Protection portfolio tools

    Read more about Unity here.

    Copy Data Management

    Enterprise Copy Data Management (eCDM) spans data copies from data protection including backup, BC, DR as well as for operational, analytics, test, dev, devops among other uses. Another term is Enterprise Copy Data Analytics (eCDA) which includes monitoring and management along with insight, awareness and of course analytics. These new offerings and initiatives tie together various capabilities across storage platforms and software defined storage management. Watch for more activity in and around eCDM and general copy data management. Read more here.

    ViPR Controller 3.0

    ViPR controller enhancements build on previous announcements, include automation as well as fail over with native replication to a standby ViPR controller. Note that there can actually be two standby controllers that are synchronized asynchronous with software built-in to ViPR. This means that there is no need for RecoverPoint or other products to do the replication of the ViPR controllers. To be clear, this is for high availability of the ViPR controllers themselves and not a replacement for HA or replication of upper layer applications, storage servers or underlying storage services. Also note that ViPR is available via open source (CoprHD via Github here). Read more here.

    MyService360

    MyService360 is a cloud based dashboard and data infrastructure monitoring management platform. Read more here.

    Virtustream Storage Cloud

    Viutustream cloud services and software tools compliments EMC (and others) storage systems as back-end for cool, cold or other bulk data storage needs. Focus is to sell primary storage to customers, then leverage back-end public cloud services for backup, archive, copy data management and other applications. This also means that the Virtustream storage cloud is not just for data protection such as archiving, backup, BC, DR it’s also for other big fast data including cloud and object native applications. Does this mean Virtustream is an alternative to other cloud and object storage services such as AWS S3, Google GCS among others? Yup. Read more here.

    What This All Means

    With the announcement of Unity and impending Dell deal, some of you might (or should) have a Dejavu moment of over a decade or so ago when Dell and EMC entered into OEM agreement around the then Clariion mid range storage arrays (e.g. predecessors of VNX and VNXe). Unity is being designed as a high performance, easy to use, flexible, scalable, cost-effective storage solutions for a broad high-volume sales and distribution channel market.

    What does Unity mean for EMC VNX and VNXe as well as XtremIO? Unity will position near where the VNXe has been positioned, along with some of the competing solutions from Dell among others. There might be some overlap with other EMC solutions, however if executed properly, Unity should open up some new markets, perhaps at the hands of some of the newer popular startups that only offer AFA vs. hybrids. Likewise I would expect Unity to appear in future converged solutions such as those via the EMC Converged business unit (e.g. VCE).

    Even with the upcoming Dell acquisition and integration, EMC continues to evolve and innovate in many areas.

    Watch for more announcements later today and throughout the week

    Cloud conversations: If focused on cost you might miss other cloud storage benefits

    Storage I/O trends

    Cloud conversations: If focused on cost you might miss other cloud storage benefits

    Drew Robb (@robbdrew) has a good piece (e.g. article) over at InfoStor titled Eight Ways to Avoid Cloud Storage Pricing Surprises that you can read here.

    Drew start’s his piece out with this nice analogy or story:

    Let’s begin with a cautionary tale about pricing: a friend hired a moving company as they quoted a very attractive price for a complex move. They lured her in with a low-ball price then added more and more “extras” to the point where their price ended up higher than many of the other bids she passed up. And to make matters worse, they are already two weeks late with delivery of the furniture and are saying it might take another two weeks.

    Drew extends his example in his piece to compare how some cloud providers may start with pricing as low as some amount only for the customer to be surprised when they did not do their homework to learn about the various fees.

    Note that most reputable cloud providers do not hide their fees even though there are myths that all cloud vendors have hidden fees, instead they list what those costs are on their sites. However that means the smart shopper or person procuring cloud services needs to go look for those fee’s and what they mean to avoid surprises. On the other hand if you can not find what extra fee’s would be along with what is or is not included in a cloud service price, to quote Jenny’s line in the movie Forest Gump, "…Run, Forest! Run!…".

    In Drew’s piece he mentions five general areas to keep an eye on pertaining cloud storage costs including:

    • Be Duly Diligent
    • Trace Out Application Interaction
    • Avoid Fixed Usage Rates
    • Beware Lowballing
    • Demand Enterprise Visibility

    Beware Lowballing

    In Drew’s piece, he includes a comment from myself shown below.

    Just as in the moving business, lowballing is alive and well in cloud pricing. Greg Schulz, an analyst with StorageIO Group, warned users to pay attention to services that have very low-cost per GByte/TByte yet have extra fees and charges for use, activity or place service caps. Compare those with other services that have higher base fees and attempt to price it based on your real storage and usage patterns.

    “Watch out for usage and activity fees with lower cost services where you may get charged for looking at or visiting your data, not to mention for when you actually need to use it,” said Schulz. “Also be aware of limits or caps on performance that may apply to a particular class of service.”

    As a follow-up to Drew’s good article, I put together the following thoughts that appeared earlier this year over at InfoStor titled Cloud storage: Is It All About Cost? that you can read here. In that article I start out with the basic question of:

    So what is your take on cloud storage, and in what context?

    Is cloud storage all about removing cost, cost cutting, free storage?

    Or perhaps even getting something else in addition to free storage?

    I routinely talk with different people from various backgrounds, environments from around the world, and the one consistency I hear when it comes to cloud services including storage is that there is no consistency.

    What I mean by this is that there are the cloud crowd cheerleaders who view or cheer for anything cloud related, some of them actually use the cloud vs. simply cheering.

    What does this have to do with cloud costs

    Simple, how do you know if cloud is cheaper or more expensive if you do not know your own costs?

    How do you know if cloud storage is available, reliable, durable if you do not have a handle on your environment?

    Are you making apples to oranges comparisons or simple trading or leveraging hype and fud for or against?

    Similar to regular storage, how you choose to use and configure on-site traditional storage for high-availability, performance, security among other best practices should be applied to cloud solutions. After all, only you can prevent cloud (or on premise) data loss, granted it is a shared responsibility. Shared responsibility means your service provider or system vendor needs to deliver quality robust solution that you can then take responsibility for configure to use with resiliency.

    For some of you perhaps cloud might be about lowering, reducing or cutting storage costs, perhaps even getting some other service(s) in addition to free storage.

    On the other hand, some of you might be

    Yet another class of cloud storage (e.g. AWS EBS) are those intended or optimized to be accessed from within a cloud via cloud servers or compute instances (e.g. AWS EC2 among others) vs. those that are optimized for both inside the cloud as well as outside the cloud access (e.g. AWS S3 or Glacier with costs shown here). I am using AWS examples; however, you could use Microsoft Azure (pricing shown here), Google (including their new Nearline service with costs shown here), Rackspace, (calculator here or other cloud files pricing here), HP Cloud (costs shown here), IBM Softlayer (object storage costs here) and many others.

    Not all types of cloud storage are the same, which is similar to traditional storage you may be using or have used in your environment in the past. For example, there is high-capacity low-cost storage, including magnetic tape for data protection, archiving of in-active data along with near-line hard disk drives (HDD). There are different types of HDDs, as well as fast solid-state devices (SSD) along with hybrid or SSHD storage used for different purposes. This is where some would say the topic of cloud storage is highly complex.

    What this means

    In my opinion there are cheap clouds (products, services, solutions) and there are low-cost options as well as there are value and premium offerings. Avoid confusing value with cheap or low-cost as something might have a higher cost, however including more capabilities or fees included that if useful can be more value. Look beyond the up-front cost aspects of clouds also considering ongoing recurring fees for actually using a server or solution.

    If you can find low-cost storage at or below a penny per GByte per month that could be a good value if it also includes many free access, retrieval GETS head and lists for management or reporting. On the other hand, if you find a service that is at or below a penny per GByte per month however charges for any access including retrieval, as well as network bandwidth fees along with reporting, that might not be as good of a value.

    Look beyond the basic price and watch out for statements like "…as low as…" to understand what is required to get that "..as low as.." price. Also understand what the extra fee’s are which most of the reputable providers list these on their sites, granted you have to look for them. If you are already using cloud services, pay attention to your monthly invoices and track what you are paying for to avoid surprises.

    From my InfoStor piece:

    For cloud storage, instead of simply focusing on lowest cost of storage per capacity, look for value, along with ability to configure or use with as much resiliency as you need. Value will mean different things depending on your needs and cloud storage servers, yet the solution should be cost-effective with availability including durability, secure and applicable performance.

    Shopping for cloud servers and storage is similar to acquiring regular servers and storage in that you need to understand what you are acquiring along with up-front and recurring fee’s to understand the total cost of ownership and cost of operations not to mention making apples to apples vs. apples to oranges comparisons.

    Btw, instead of simply using lower cost cloud services to cut cost, why not also use those capabilities to create or park another copy of your important data somewhere else just to be safe…

    What say you about cloud costs?

    Ok, nuff said, for now…
