The Drobo 5N is equipped with a single Gigabit Ethernet port for network connectivity and connects directly to your network to make sharing your data easy. Just plug it into any switch or wireless router and you're ready to go. You can even connect the Drobo 5N directly to the Ethernet port on your computer without having to configure any settings.

Capacity AND Performance

Capacity and Performance

Data-Aware Tiering technology, usually reserved for business-class storage solutions, is also available in this desktop Drobo. It intelligently uses the high-performance flash in SSDs to accelerate performance of the storage array, allowing applications such as Adobe Premiere and Apple Aperture fast access to data. To keep capacity of the Drobo at a maximum, the Drobo Accelerator Bay accepts an industry-standard mSATA SSD, leaving all five 3.5" drives bays available for high-capacity HDDs.

If getting the fastest performance possible is your thing, you can also load up every drive bay with SSDs. Drobo gives you the flexibility to choose.

Power Protecting Your Critical DataPower Protecting Your Critical Data

Drobo doesn't just protect you from a drive failure, but also from potential data loss after a power outage. Often found only in arrays that cost tens of thousands of dollars, Drobo 5D includes a battery that protects all data in memory, or cache, that is, data on its way to the drives.

When power spontaneously goes away, the battery keeps the Drobo alive long enough for the data to be written to non-volatile storage, ensuring your important information is safe. This battery recharges itself and is designed to last for the life of the product.

Designed for You

Designed for You

Drobos have always been space efficient and the Drobo 5N is no exception. It was designed from the ground up to provide very high capacity without taking up a lot of your valuable desk space. It is compact mostly because of Drobo's unique carrierless drive-bay design, allowing drives to be installed very close to each other. The result is an attractive storage array that's up to 34% smaller than the leading competition.

Drobo 5N is also significantly quieter than previous-generation Drobos due to its tuned, large, variable-speed cooling fan. You can even configure Drobo to spin down drives when they're not in use to further reduce noise and save energy.


RAID and BeyondRAID ComparsionBeyondRAID:

What's BeyondRAID? Storage without limitations.

BeyondRAID technology, built into every Drobo, delivers all of the benefits of traditional RAID, while providing much more and leaving many of the limitations behind. This next-generation of redundant storage technology brings together enhanced protection, reliability, expandability, and ease-of-use.

Drobos, based on BeyondRAID, interact with computing systems in the same manner as storage arrays using traditional RAID, so installing a Drobo allows you to maintain your current operating system and file system. This eliminates the challenges and costs when moving to a new storage technology.

Problems with Traditional RAID

Traditional RAIDDeveloped in the 1980s, RAID (Redundant Array of Inexpensive Disks) was designed to pool disk drives together for increased capacity and reliability for data storage. It has been preventing single disk drive failures causing data loss, and has been used in almost every enterprise data center for decades.

While reliable, the complexity of RAID is a huge challenge for small businesses and consumers. RAID has a high learning curve with many options, levels, and unfamiliar terminology like striping, mirroring, and parity.

There are several primary challenges with traditional RAID:

  • Lock-in of RAID Levels
    To change RAID levels, most storage arrays require the data to be moved off, reconfigured, and then moved back on. If you want to move to RAID 6 from RAID 5 for protection against two drive failures, you need to reinitialize and start over. This process could take days to complete.
  • Lack of Expandability
    Once drives are configured into a RAID pool, expandability is impossible unless you have a lot of time, or experience. If you want to add more storage capacity, the solution is to create a new RAID pool, leaving you with another chunk of storage to manage – or you can just reinitialize and start over.
  • Drive Failures Create Big Risks
    When a drive fails, most RAID implementations enter a state where data loss will occur if another drive falters before the user replaces the failed drive. Also, performance is hampered when in this debilitated state.

Moving Beyond RAID

Drobo’s BeyondRAID technology solves the fundamental issues that traditional RAID can’t. Built on the foundation of traditional RAID, BeyondRAID adds a layer of virtualization that chooses the correct protection algorithm based on data availability needs at any given moment. Since the technology works at the block level, it can write blocks of data that alternate between RAID protection levels.

If you need to add storage capacity to a Drobo, simply insert additional disk drives or replace the smallest disks with larger ones – no need to change RAID levels, purchase a new storage array, or go through the complex administration of pooling RAID groups.

The BeyondRAID feature can even switch from single to dual disk redundancy with just the click of your mouse through Drobo Dashboard. This ensures enterprise-level dual parity data protection, when needed. If a drive happens to fail, Drobo will automatically re-layout the data to the remaining drives, returning it to a protected state with no user interaction.

Thin Provisioning is a fundamental capability of BeyondRAID, allowing for infinite capacity expansion by just replacing a drive with a larger one.

Instant Expansion occurs when a new, or larger, drive is inserted without any disruption in service.

Drobo's volumes are Smart Volumes, pulling needed storage from a common pool and then returning deleted blocks back to the common pool, preventing free space from being tied up by any particular server.

Mixed Drive Utilization allows you to insert any drive, of any size, or any type, and Drobo will optimally use it - check out our interactive Capacity Calculator.

Automatic Protection Levels ensures the best algorithm is used to protect from drive failure depending on the number of drives that are inserted, without any user configuration. There is no need to learn about RAID levels or what mirroring or striping is.

Dual Disk Redundancy enhances BeyondRAID protection by guarding from multiple drive failures in a short period of time. Even if two drives fail, BeyondRAID will attempt to use the remaining drives to return to a protected state.

Virtual Hot Spare utilizes all drives at all time with no drives sitting idle waiting for one to fail. With some traditional RAID systems, a drive can be marked as a "hot spare", waiting on standby for a drive failure so it can take over. That's just a unutilized drive that you have to pay for taking up a valuable drive bay.

Drobos are Data Aware, intelligently handling data for added resiliency, performance, and management. Being Data Aware allows the Drobo to have a capacity gauge on the front, quickly recover in the event of a drive failure, enable intelligent tiering of data, and much more.

Drive Re-ordering allows Drobo disk packs to be moved to another Drobo, and even re-ordered, while still functioning - try that with RAID.

How BeyondRAID Works

Now that we've looked at how BeyondRAID compares with traditional RAID and the value that it brings, let's see how BeyondRAID works.

how BeyondRAID compares with traditional RAID Works
The sections of the RAID stack are drastically reinvented in a Drobo—and it all has to
do with how drives are pooled (disk pack) and the way data is stored (BeyondRAID virtualization).

Technology:

BeyondRAID™ Technology

Most modern storage arrays aggregate disks and prevent against single drive failures using a 20-year-old technology called RAID (Redundant Array of Independent Disks). While RAID has served many businesses well, it requires up-front knowledge of its functionality and has many shortcomings. BeyondRAID technology built into every Drobo addresses these shortcomings and makes virtualizing disk drives usable by everyone. BeyondRAID provides these enhancements over traditional RAID:

  • Thin Provisioning as a fundamental capability allows for infinite capacity expansion by just replacing a drive with a larger one
  • Instant Expansion occurs when a new, or larger, drive is inserted without any disruption in service
  • Mixed Drive Utilization allows you to insert any drive, of any size, or any type, and Drobo will optimally use it - check out our interactive Capacity Calculator
  • Automatic Protection Levels ensures the best algorithm is used to protect from drive failure depending on the number of drives that are inserted without any user configuration
  • Dual Disk Redundancy enhances BeyondRAID protection by guarding from multiple drive failures
  • Virtual Hot Spare utilizes all drives at all time - no drives sitting idle waiting for one to fail
  • Drobos are Data Aware, intelligently handling data for added resiliency, performance, and management
  • Drive Re-ordering allows Drobo disk packs to be moved to another Drobo, and even re-ordered, while still functioning - try that with RAID

DroboAppsDrobo Apps
All File Sharing Drobos support the installation of Drobo Apps - applications that enhance the functionality of your Drobo on your network. Drobo Apps are community created and run on the Linux-based operating system embedded in Drobo.

Data-Aware Tiering

Data-Aware Tiering SANs allow businesses to consolidate storage resources and share that storage across all connected servers and their applications. The reality is that different applications have different workloads. Transactional databases require different storage behavior than streaming media applications. Traditional storage has treated all workloads as equal, not optimizing for any of them.

It's called the Drobo Accelerator Bay and it accepts an industry-standard mSATA SSD. So you can add flash to your Drobo without consuming one of the standard drive bays, which are best used to maximize capacity. The mSATA SSD is used to accelerate smaller and random reads from the Drobo, while the HDDs are used for storing and streaming larger data such as photos, video, and user documents.

File and Operating System Agnostic

Drobo and its underlying BeyondRAID technology currently support the Windows and Mac platforms, with file system support for NTFS, HFS+ and FAT32. Since Drobo is a block level system, it easily adapts to almost any environment.

Mixed Drive Capacity Utilization

Grow storage to meet your data capacity needs with minimal effort. To add capacity, simply insert a new hard disk or replace the smallest disk with a larger one, even when all four disk bays are full. Unlike traditional RAID systems, the BeyondRAID technology enables IT managers to efficiently mix and match disk brands, capacities, and speeds. This allows for continuous expansion as disk capacities grow. Now, expansion is automatic, instantaneous and access to data is always maintained.

To find out exactly how much free capacity you'll have with your choice of disk capacities, try out our interactive Capacity Calculator on tab.

Redundant Safety

Drobo can ensure your data is safe even if a hard disk fails. You'll feel safer knowing that if disks do fail, Drobo automatically enters a state of self-healing wherein it relays out your data across the remaining healthy disks and sectors.

Proportional Rebuild Times

The time it takes Drobo to rebuild data after a drive failure or removal is proportional to the amount of data stored in the pool — meaning the less capacity that is used, even on a 2TB disk, the shorter your rebuild times will be. This is superior to traditional RAID, which lacks proportional rebuild times, and is forced relay out every drive block even if it does not contain user data.

Since Drobo is "Data Aware", it tracks where data is on each disk, so it can differentiate between used and unused portions of disk. This expedites rebuild times and reduces your risk of losing data to an additional disk failure. In short, your data is safer on a Drobo.

Self-Healing

When Drobo detects a "bad" hard disk, it proactively advises you with a series of warnings ranging from a blinking red LED on its front panel, to pop-up alerts in Drobo Dashboard, to email alerts. What Drobo does next is exceptional. It enters a self-healing mode where it repairs around the bad sector or disk, and will work until it returns to the safest state possible. If Drobo has sufficient time and free capacity (indicated by all lights returning to a solid green state), it can even withstand additional hard disk failures — that's the power of self-healing.

Storage Virtualization

BeyondRAID was designed from the ground up to allow the storage capacity of the array to expand and contract. BeyondRAID makes this a simple process by utilizing a technology called "virtualization." Virtualization provides a layer of abstraction between the data requested by the file system and the physical location of that data on the disk drives. A given piece of data can be located on any drive, and on any physical location on that drive. This is what makes adding a drive to a Drobo so simple. The new drive just provides additional places to store data.

Virtualization is what enables BeyondRAID to effortlessly change the data arrangement on the drives, for example, changing data stored as a mirror into data stored as parity stripe, without interrupting the user access to data. Virtualization completely decouples the physical space available in the array from the space reported to the operating system. This is how BeyondRAID is able to eliminate the need to manually expand/contract the file system as more space becomes available or is removed.

Thin Provisioning

Thin provisioning is a technical term that describes how the BeyondRAID technology communicates with your operating system. BeyondRAID communicates with your OS about how much disk space you have, up to 16TB (this varies with older operating and file systems). Specifying a larger amount of storage than is physically available allows you to grow into the volume without having to reformat or migrate your data in order to add capacity. BeyondRAID automatically also reclaims space as you delete files.

Self-Managing

Drobo is highly automated storage. There are no complex configuration screens, DIP switches, confounding choices, web consoles or other complications that prevent so many other storage devices from working out of the box.

Drive Reordering

One long-standing requirement inherent in traditional RAID-based systems was that if for some reason you needed to remove the drives, you'd have to replace the drives in the exact same order. When you remove your disks from Drobo, you can put them back in any order you like.
