Supporting IT growth demand during economic uncertain times

Doing more with less, doing more with what you have or reducing cost have been the mantra for the past several years now.

Does that mean as a trend, they are being adopted as the new way of doing business, or simply a cycle or temporary situation?

Reality is that many if not most IT organizations are and will remain under pressure to stretch their budgets further for the immediate future. Over the past year or two some organizations saw increases in their budgets however also increased demand while others saw budgets fixed or reduced while having to support growth. On the other hand, there is no such thing as an information recession with more data being generated, moved, processed, stored and retained for longer periods of time.

Industry trend: No such thing as a data recession

Something has to give as shown in the following figure which is that on one curve there is continued demand and growth, while another curve shows need to reduce costs while another reflects the importance of maintaining or enhancing service level objectives (SLOs) and quality of service (QoS).

Enable growth while removing complexity and cost without compromising service levels

One way to reduce costs is to inhibit growth while another is to support growth by sacrificing QoS including performance, response time or availability as a result of over consolidation, excessive utilization or instability as a result of stretching resources to far. Where innovation comes into play is finding and fixing problems vs. moving or masking them or treating symptoms vs. the real issue and challenge. Innovation also comes into play by identifying both near term tactical as well as longer term strategic means of taking complexity and cost out of service delivery and the resources needed to support them. For example determining the different resources and processes involved in delivering an email box of a given size and reliability. Another being supporting a virtual machine (VM) with a given performance and capacity capability. Yet another scenario is a file share or home directory of a specific size and availability. By streamlining work flows, leveraging automation and other tools to enforce polices as well as adopting new best practices complexity and thereby costs can be reduced. The net rest is a lower cost to provide a given service to a specific level which when multiplied out over many users or instances, results in cost savings however also productivity gains.

The above is all good and well for longer term strategic and where you want to go or get to, however what can be done right now today?

Here are a few tips to do more with what you have while supporting growth demands

If you have service level agreements (SLAs) and SLOs as part of your service category, review with your users as to what they need vs. what they would like to have. What you may find is that your users want or expect a given level of service, yet would be happy and ok with moving to a cloud service that had lower SLO and SLA expectations if lower cost. The previous scenario would be an indicator that you users want and thus you give them a higher level of service, yet their requirements are actually lower than what is expected. On the other hand if you do not have SLOs and SLAs aligned with cost for the services then set them up and review customer or client expectations, needs vs. wants on a regular basis. You might find out that you can stretch your budget by delivering a lower (or higher) class of services to meet different users requirements than what was assumed to be the case. In the case of supporting a better class of service, if you can use an SSD enabled solution to reduce latency or wait times and boost productivity, more transactions or page views or revenue per hour, that could prompt a client to request that capability to meet their business needs.

Reduce your data footprint impact in order to support growth using the ABCDs of data footprint reduction (DFR), that is Archive (email, file, database), Backup modernization, Compression and consolidation, Data management and dedupe, storage tiering among other techniques.

Storage, server virtualization and optimization using capacity consolidation where practical and IO consolidation to fast storage and SSD where possible. Also review storage configuration including RAID and allocation to identity if any relatively easy changes can improve performance, availability, capacity and energy impact.

Investigate available upgrades and enhancements to your existing hardware, software and services that can be applied to provide breathing room within current budgets while evaluating new technologies.

Find and fix problems vs. chasing false positives that provide near term relief only to have the real issue reappear. Maximize your budgets by identifying where people time and other resources are being spent due to processes, work flows, technology configuration complexity or bottlenecks and address those.

Enhance and leverage existing management measurements to gain more insight along with implementing new metrics for End to End (E2E) situational awareness of your environment which will enable effective decision making. For example you may be told to move some function to the cloud as it will be cheaper, yet if you do not have metrics to indicate one way or the other, how can that be an informed decision? If you have metrics that show your cost for the same service being moved to a cloud or managed service provider as well as QoS, SLO, SLA, RTO, RPO and other TLAs, then you can make informed decisions. That decision may still be to move functions to a cloud or other service even if in fact it is more expensive compared to what you can provide it for in order that your resources can be directed to supporting other important internal functions.

Look for ways to reduce cost of a service delivered as opposed to simply cutting costs. They sound like one and the same, however if you have metrics and measurements providing situational awareness to know what the cost of a service is, you can also then look at how to streamline those services, remove complexity, reduce workflow, leverage automation there by removing cost. The goal is the same, however how you go about removing cost can have an impact on your return on innovation not to mention customer satisfaction.

Also be an informed shopper, have a forecast or plan on what you will need and when, along with what you must have (core requirements) vs. what you would like to have or want. When looking at options, balance what is needed and then if you can get what you want or would like for little or no extra cost if they add value or enable other initiatives. Part of being an informed shopper is having support of the business to be able to procure what you want or need which means aligning technology resources and their cost to delivery of business functions and services.

What you need vs. what you want
In a recent interview with the associated press (AP) the reporter wanted to know my comments about spending vs. saving during economic tough times (you can read the story here). Basically my comments were to spend within your means by identifying what you need vs. what you want, what is required to keep the business running or improve productivity and remove cost as opposed to acquiring nice to have things that can wait. Sure I would like to have a new 85 to 120" 3D monitor for my workstation that could double as a TV, however I do not need or require it.

On the other hand, I recently upgraded an existing workstation adding a Hybrid Hard Disk Drive (HHDD) and some additional memory, about a $200USD investment that is already paying for itself via increased productivity. That is instead of enjoying a cup of dunkin donut coffee while waiting for some tasks to complete on that system, Im able to get more done in a given amount of time boosting productivity.

For IT environments this means looking at expenditures to determine what is needed or required to keep things running while supporting near term strategic and tactical initiatives or pet projects.

For vendors and vars, if things have not been a challenge yet, now they will need to refine their messages to show more value, return on innovation (ROI) in terms of how to help their customers or prospects stretch resources (budgets, people, skill sets, products, services, licenses, power and cooling, floor space) further to support growth, while removing costs without compromising on service delivery. This also means a shift in thinking of short term or tactical cost cutting to longer term strategic approaches of reducing costs to deliver a service or resources.

VMware vSphere v5 and Storage DRS

Here is a link to a recent guest post that I was invited to do over at The virtualization Practice (TVP) pertaining to the recent VMware vSphere 5.0 announcement. A theme of the vSphere 5.0 launch is reducing complexity, enabling automation, and supporting scaling with confidence for cloud and virtual environments. As a key component for supporting cloud, virtual and dynamic infrastructure environments, vSphere V5.0 includes many storage related enhancements and new features including Storage Distributed Resource Scheduler (SDRS).

Measuring Windows performance impact for VDI planning

Here is a link to a recent guest post that I was invited to do over at The Virtualization Practice (TVP) pertaining to measuring the impact of Windows Boot performance and what that means for planning for Virtual Desktop Infrastructure (VDI) initiatives.

With Virtual Desktop Infrastructures (VDI) initiatives adoption being a popular theme associated with cloud and dynamic infrastructure environments a related discussion point is the impact on networks, servers and storage during boot or startup activity to avoid bottlenecks. VDI solution vendors include Citrix, Microsoft and VMware along with various server, storage, networking and management tools vendors.

A common storage and network related topic involving VDI are boot storms when many workstations or desktops all startup at the same time. However any discussion around VDI and its impact on networks, servers and storage should also be expanded from read centric boots to write intensive shutdown or maintenance activity as well.

Having an understanding of what your performance requirements are is important to adequately design a configuration that will meet your Quality of Service (QoS) and service level objectives (SLOs) for VDI deployment in addition to knowing what to look for in candidate server, storage and networking technologies. For example, knowing how your different desktop applications and workloads perform on a normal basis provides a baseline to compare with during busy periods or times of trouble. Another benefit is that when shopping for example storage systems and reviewing various benchmarks, knowing what your actual performance and application characteristics are helps to align the applicable technology to your QoS and SLO needs while avoiding apples to oranges benchmark comparisons.

Check out the entire piece including some test results using the hIOmon tool from hyperIO to gather actual workstation performance numbers.

Keep in mind that the best benchmark is your actual applications running as close to possible to their typical workload and usage scenarios.

Also keep in mind that fast workstations need fast networks, fast servers and fast storage.

Getting SASy, the other shared storage option for disk and SSD systems

Here is a link to a recent guest post that I was invited to do over at The Virtualization Practice (TVP) pertaining to Getting SASsy, the other shared server to storage interconnect for disk and SSD systems. Serial Attached SCSI (SAS) is better known as an interface for connecting hard disk drives (HDD) to servers and storage systems; however it is also widely used for attaching storage systems to physical as well as virtual servers. An important storage requirement for virtual machine (VM) environments with more than one physical machine (PM) server is shared storage. SAS has become a viable interconnect along with other Storage Area Network (SAN) interfaces including Fibre Channel (FC), Fibre Channel over Ethernet (FCoE) and iSCSI for block access.

Industry trend: People plus data are aging and living longer

Lets face it, people and information are living longer and thus there are more of each along with a strong interdependency by both.

People living and data being retained longer should not be a surprise, take a step back and look at the bigger picture. There is no such thing as an information recession with more data being generated, processed, moved and stored for longer periods of time not to mention that a data object is also getting larger.

Industry trend and performance

By data objects getting larger, think about a digital photo taken on a typical camera ten years ago which whose resolution was lower and thus its file size would have been measured in kilo bytes (thousands). Today megapixel resolutions are common from cell phones, smart phones, PDAs and even larger with more robust digital and high definition (HD) still and video cameras. This means that a photo of the same object that resulted in a file of hundreds of Kbytes ten years ago would be measured in Megabytes today. With three dimensional (3D) cameras appearing along with higher resolution, you do not need to be a rocket scientist or industry pundit to figure out what that growth trend trajectory looks like.

However it is not just the size of the data that is getting larger, there are also more instances along with copies of those files, photos, videos and other objects being created, stored and retained. Similar to data, there are more people now than ten years ago and some of those have also grown larger, or at least around the waistline. This means that more people are creating and relying on larger amounts of information being available or accessible when and where needed. As people grow older, the amount of data that they generate will naturally increase as will the information that they consume and rely upon.

Where things get interesting is that looking back in history, that is more than ten or even a hundred years, the trend is that there are more people, they are living longer, and they are generating larger amounts of data that is taking on new value or meaning. Heck you can even go back from hundreds to thousands of years and see early forms of data archiving and storage with drawings on walls of caves or other venues. I Wonder if had the cost (and ease of use) to store and keep data had been lower back than would there have been more information saved? Or was it a case of being too difficult to use the then state of art data and information storage medium combined with limited capacities so they simply ran out of storage and retention mediums (e.g. walls and ceilings)?

Lets come back to the current for a moment which is another trend of data that in the past would have been kept offline or best case near line due to cost and limits or constraints are finding their way online either in public or private venues (or clouds if you prefer).

Thus the trend of expanding data life cycles with some types of data being kept online or readily accessible as its value is discovered.

Evolving data life cycle and access patterns

Here is an easy test, think of something that you may have googled or searched for a year or two ago that either could not be found or was very difficult to find. Now take that same search or topic query and see if anything appears and if it does, how many instances of it appear. Now make a note to do the same test again in a year or even six months and compare the results.

Now back to the future however with an eye to the past and things get even more interesting in that some researchers are saying that in centuries to come, we should expect to see more people not only living into their hundreds, however even longer. This follows the trend of the average life expectancy of people continues to increase over decades and centuries.

What if people start to live hundreds of years or even longer, what about the information they will generate and rely upon and its later life cycle or span?

More information and data

Here is a link to a post where a researcher sees that very far down the road, people could live to be a thousand years old which brings up the question, what about all the data they generate and rely upon during their lifetime.

Ok, now back to the 21st century and it is safe to say that there will be more data and information to process, move, store and keep for longer periods of time in a cost effective way. This means applying data footprint reduction (DFR) such as archiving, backup and data protection modernization, compression, consolidation where possible, dedupe and data management including deletion where applicable along with other techniques and technologies combined with best practices.

Will you out live your data, or will your data survive you?

These are among other things to ponder while you enjoy your summer (northern hemisphere) vacation sitting on a beach or pool side enjoying a cool beverage perhaps gazing at the passing clouds reflecting on all things great and small.

Clouds: Dont be scared, however look before you leap and be prepared

Ok, nuff said for now.

Unified storage systems showdown: NetApp FAS vs. EMC VNX

Unified storage systems that support concurrent block, file and in some cases object based access have become popular in terms of industry adoption as well as customer deployments with solutions from many vendors across different price bands, or market (customer) sectors. Two companies that are leaders in this space are also squared off against each other (here and here) to compete for existing, each others, as well as new customers in adjacent or different markets. Those companies are EMC and NetApp that I have described as two similar companies on parallel tracks offset by time.

Two companies on parralel tracks offset by time

Recently I was asked to provide some commentary about unified storage systems in general, as well as EMC and NetApp that you can read here, or view additional commentary on related themes here, here and here. EMC has a historical block based storage DNA that has evolved to file and object based while NetApp originated in the file space having moved into block based storage along with object based access. EMC converged various product technologies including those developed organically (e.g. internally) as well as via acquisition as part of their unified approach. NetApp who has had a unified produce has more recently added a new line of block products with their acquisition of Engenio from LSI. Obviously there are many other vendors with unified storage solutions that are either native (e.g. the functionality is built into the actual technology) or by parterning with others to combine their block or file based solutions as a unified offering.

What is unified storage, what does it enable, and why is it popular now?
Over the past couple of years, multifunction systems that can do both block- and file-based storage have become more popular. These systems simplify the acquisition process by removing the need to choose while enabling flexibility to use something else later. NAS solutions have evolved to support both NFS and CIFS and other TCP-based protocols, including HTTP and FTP, concurrently. NAS or file sharing–based storage continues to gain popularity because of its ease of use and built-in data management capabilities. However, some applications, including Microsoft Exchange or databases, either require block-based storage using SAS, iSCSI, or Fibre Channel, or have manufacture configuration guidelines for block-based storage.

Multi protocol storage products enable the following:

  • Acquisition and installation without need for a specialist
  • Use by professionals with varied skills
  • Reprovisioning for different applications requirements
  • Expansion and upgrades to boost future capacity needs
  • Figure 1 shows variations of how storage systems, gateways, or appliances can provide multiple functionality support with various interfaces and protocols. The exact protocols, interfaces, and functionality supported by a given system, software stack, gateway, or appliance will vary by specific vendor implementation. Most solutions provide some combination of block and file storage, with increasing support for various object-based access as well. Some solutions provide multiple block protocols concurrently, while others support block, file, and object over Ethernet interfaces. In addition to various front-end or server and application-facing support, solutions also commonly utilize multiple back-end interfaces, protocols, and tiered storage media.

    Unified and multiprotocol storage, learn more in Cloud and Virtual Data Storage Networking (CRC Press, 2011)

    Figure 1: Multi protocol and function unified storage examples

    For low-end SMB, ROBO, workgroup, SOHO, and consumers, the benefit of multi protocol and unified storage solutions is similar to that of a multifunction printer, copier, fax, and scanner—that is, many features and functionality in a common footprint that is easy to acquire, install, and use in an affordable manner.

    For larger environments, the value proposition of multi protocol and multi functionality is the flexibility and ability to adapt to different usage scenarios that enable a storage system to take on more personalities. What this means is that by being able to support multiple interfaces and protocols along with different types of media and functionality, a storage system becomes multifunctional. A multifunction storage system may be configured for on-line primary storage with good availability and performance and for lower-cost, high-capacity storage in addition to being used as backup target. In other scenarios, a multifunction device may be configured to perform a single function with the idea of later redeploying it to use a different personality or mode of functionality.

    An easy way to determine whether you need multi protocol storage is to look at your environment and requirements. If all you need is FC, FCoE, SAS, iSCSI, or NAS, and a multi protocol device is going to cost you more, it may not be a good fit.

    If you think you may ever need multi protocol capability, and there’s no extra charge for it, go ahead. If you’re not being penalized in performance, extra management software fees, functionality or availability, and you have the capability, why wouldnt you implement a unified storage system?

    Look for products that have the ability to scale to meet your current and future storage capacity, performance, and availability needs or that can coexist under common management with additional storage systems.

    Vendors of unified storage in addition to EMC and NetApp include BlueArc, Fujitsu, Dell, Drobo, HDS (with BlueArc), HP, IBM, Huawei, Oracle, Overland, Quantum, Symantec and Synology among others.

    So what does this all mean? Simple, if you are not already using unified storage in some shape or form, either at work or perhaps even at home, most likely it will be in your future. Thus the question of not if, rather when, where, with what and how.

    Ok, nuff said for now.

    Dell Storage Forum 2011 revisited

    About a month ago I was invited by Dell to make a quick trip down to Orlando to attend the Dell Storage Forum 2011 (e.g. twitter #dellsf11). Given that on Tuesday June 7th Minneapolis was having a heat wave with 100 degree (F) temperatures, it was actually cooler in Orlando.

    Make no mistake however, there were plenty of technologies that were cool and being kept cool at the Hilton adjacent to Disney as Dell continues to expand their footprint into the hot data storage market. The event brought together three aspects of the Dell storage story which were the mergers of the recently acquired Compellent user group with the Dell Equallogic user group along with the rest of the Dell storage and data management lineup. While the limelight was focused on Compellent and Equalogic, the Dell disk Dudes (and Dudettes e.g. Gina Rosenthal aka twitter @gminks and Sheryl Koenigsberg aka twitter @storagediva ) have been involved with storage for many years in addition to the recent acquisitions.

    During the event I was invited to tag along with Roger Lund (twitter @rogerlund) an IT customer of Dells and Ed Saipetch (twitter @edsai) an Dell partner to go talk with the Dell NAS dudes (aka Unified, clustered, grid, rain, big data, bulk, scale out NAS) team formerly known as Exanet. The team is mix of Dell, former Exanet and new members who have been relatively quietly enhancing their technology in addition to creating packaged solution bundles with other Dell products such as the FS7500 (coupled with EqualLogic). For those not familiar with Exanet, have a read here or hear and for those not familiar with scale out NAS (aka bulk, grid, clustered, big data, etc) have a read here.

    There are lots of interesting things in the works or possible and the team that we spoke with are full of energy, ideas, support from management not to mention having some interesting technology tools to work with ranging from Ocarina (data footprint reduction aka DFR), Kace, Scalent, Powervault MD series, servers and micro servers, not to mention EqualLogic and Compellent among others including those from various partners.

    NAS was not the only thing cool at the event, there was the Dell object storage solution (aka DX) based on Caringo CAS (Content Addressable Storage) OEM software technology that has been the Rx (prescription) for healthcare, medical and other archives. Keep in mind that Dell also earlier this year acquired Insight one that just happens to be involved with healthcare and medical data or information management.

    Speaking of archives and objects there was also some activity this past week with Dell and Rainstor making an announcement of their joint solutions in addition. Speaking of making sure that data on Dell storage remains available, accessible and protected, preserved and served, there were also backup/restore as well as many other pieces of technology, services and solutions. There was also a good presence by Dell partners at the event including Brocade, Commvault, Quantum and Symantec among others.

    Here is a link to a video from when I was a guest with hosts Cali Lewis and John McArthur on the Wikibon/Silicon Angle The Cube show while at the Dell Event. During the discussion we had some fun as well as discussed not to be scared of clouds and virtualization, however look before you leap, doing your homework to be prepared along with other themes in my new book Cloud and Virtual Data Storage Networking (CRC Press).

    Speaking of Dell, I had a nice conversation with Michael Dell during the storage beers tweet up. Did we talk about SMB or SOHO NAS, SSD, tape, HHDD, Brocade, block vs. file vs. object, data footprint reduction, big backup vs. big data, clouds, 3PAR, Equallogic vs. Compellent, HP vs. EMC?

    Nope, we talked about the Dallas Mavericks (who went on to win the NBA title for 2011), social media and other items. If you have never meet Michael Dell, he is one of the most relaxed, confident and approachable CEOs of any big or large company I have meet.

    In addition to visiting with Michael Dell, I also had the pleasure of meeting many other great people from Dell, their partners and others face to face including many twitter tweeps. All in all it was a great day and a half trip down to the Dell event, look forward to seeing and hearing more from Dell in the future.

    Oh, and for disclosure purposes, Dell covered my RT coach class airfare while I picked up my own hotel, airport transfers, parking and incidentals.

    Thanks again to Gina Rosenthal for making it all happen!

    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.

    Cheers gs

    Major themes that will be discussed include:

    • Who is doing what with various storage solutions and tools
    • Is RAID still relevant for today and tomorrow
    • Are hard disk drives and tape finally dead at the hands of SSD and clouds
    • What am I routinely hearing, seeing or being asked to comment on
    • Enabling storage optimization, efficiency and effectiveness (performance and capacity)
    • What do I see as opportunities for leveraging various technologies, techniques,trends
    • Supporting virtual servers including re-architecting data protection
    • How to modernize data protection (backup/restore, BC, DR, replication, snapshots)
    • Data footprint reduction (DFR) including archive, compression and dedupe
    • Clarifying cloud confusion, don’t be scared, however look before you leap

    In addition this two day seminar will look at what are some new and improved technologies and techniques, who is doing what along with discussions around industry and vendor activity including mergers and acquisitions. Greg will also preview the contents and themes of his new book Cloud and Virtual Data Storage Networking (CRC) for enabling efficient, optimized and effective information services delivery across cloud, virtual and traditional environments.

    Buzzwords and topic themes to be discussed among others include:
    E2E, FCoE and DCB, CNAs, SAS, I/O virtualization, server and storage virtualization, public and private cloud, Dynamic Infrastructures, VDI, RAID and advanced data protection options, SSD, flash, SAN, DAS and NAS, object storage, application optimized or aware storage, open storage, scale out storage solutions, federated management, metrics and measurements, performance and capacity, data movement and migration, storage tiering, data protection modernization, SRA and SRM, data footprint reduction (archive, compress, dedupe), unified and multi-protocol storage, solution bundle and stacks.

    Using Removable Hard Disk Drives (RHDDs)

    Removable hard disk drives (RHDD) are a form of removable media which includes magnetic tape that address many common use cases. Usage scenarios include enabling bulk data portability for larger environments or for D2D backup where the media needs to be physically moved offsite for small and mid sized environments. RHDDs include among others those from Imation such as the Odyssey (which is what I use) and the Prostor RDX (OEMed by Imation and others). RHDD, tape along with other forms of portable media including those that use flash by being removable and portable presumable should have some extra packaging protection to safeguard against static shock in addition to supporting encryption capabilities.

    Compared to disks including RHDD, tape for most and particularly larger environments should have an overall lower media cost for parking, preserving and when needed serving inactive or archived data (e.g. the changing roll of tape from day to back up to archive). Of course your real costs will vary by use in addition to how combined with data footprint reduction and other technologies.

    A big benefit of RHDDs is that they are random meaning data can be searched and found quickly vs. tape media which has great sequential or streaming capabilities if you have a system that can support that ability. The other benefit of RHDD is that depending on their implementation, they should plug and play with your systems appearing as disk without any extra drivers or configuration or software tools making for ease of use. Being removable they can be used for portability such as sending data to a cloud or MSP as part of an initial bulk copy, or sending data offset or taking home as part of an offsite backup, data protection or BC/DR strategy as well as being used for archiving. The warning with RHDD is their cost per TByte will generally be higher than compared to tape as well as having to have a docking station or specific drive interface depending on specific product and configuration.

    RHDD are a great compliment to traditional fixed or non removable disk, Hybrid Hard Disk Drive (HHDD) and Solid State Device (SSD) based storage as well as coexist with cloud or MSP backup and archive solutions. The smaller the environment the more affordable using RHDD become vs. tape for backup and archive operations or when portability is required. Even if using a cloud or managed service provider (MSP) backup provider, network bandwidth costs, availability or performance may limit the amount of data that can be moved in a cost effective way. For example placing an archive and gold or master copy of your static data on a RHDD that may be kept on site in a safe off-site place and then sending data that is routinely changed to the cloud or MSP provider (think full local and offsite plus partial full and incremental in the cloud).

    By leveraging archiving and data footprint reduction (DFR) techniques including dedupe and compression, you can stretch your budget by sending less data to cloud or MSP services while using removable media for data protection. You would be surprised how many TBytes of data can be kept in a safe deposit box. For my own business, I have used RHDDs for several years to keep gold master copies as well as archives offsite as part of a disk to disk (D2D) or D2D2RHDD strategy. The data protection strategy is also complimented by sending active data to a cloud backup MSP (encrypted of course). It might be belt and suspenders, however it is also eating my own dog food practicing what I talk about and the approach has proven itself a few times.
