Every Drobo product comes with the revolutionary BeyondRAID
storage technology — the next generation of redundant disk protection.
BeyondRAID not only keeps your data safe, but will also increases
uptime and availability. BeyondRAID technology offers several
improvements over traditional RAID-based storage systems, including the
flexibility to replace failed disks, increase capacity and with a
single click switch between single- and dual-disk redundancy, all
without costly downtime.
Key features of BeyondRAID include:
Data protection against hard disk failure
Instant capacity expansion without downtime
The DroboElite connects seamlessly to your
existingTCP/IP network and utilizes industry-standard iSCSI protocol
with optional CHAP authentication to provide simple, consolidated iSCSI
storage for your servers.
File and Operating System Agnostic
its underlying BeyondRAID technology currently support the Windows,
Mac, VMware, and Linux* platforms, with file system support for NTFS,
HFS+, EXT3, and VMFS. Since DroboElite is a block-level system, it
easily adapts to almost any environment.
Mixed Drive Capacity Utilization
Grow your storage to meet your data
capacity needs with minimal effort. To add capacity, customers can
simply insert a new hard disk or replace the smallest disk with a larger
one, even when all eight 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. Expansion is automatic,
instantaneous and access to data is always maintained.

Utilizing dual-disk redundancy, DroboElite’s
BeyondRAID technology can ensure your data is safe even if up to two
drives fail simultaneously — all without a moment of downtime. You can
even switch between single- and dual-disk redundancy with a single
click. You’ll feel safer knowing that if drives do fail, DroboElite
automatically enters a state of self-healing in which it relays out
your data across the remaining healthy drives and sectors. If
a drive fails, BeyondRAID technology always returns the drive array
back to the safest state possible.
Proportional Rebuild Times
Since DroboElite is “Data Aware”, it tracks
where data is on each drive, so it can differentiate between used and
unused portions of the drive. This expedites rebuild times and reduces
your risk of losing data to an additional disk drive failure. In short,
your data is safer on a Drobo.
The time it takes DroboElite 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. 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.
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
drive space you have; up to 16TB per volume.¹ 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
When DroboElite detects a "bad" hard drive,
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 and email alerts. What DroboElite does next is exceptional. It
enters a self-healing mode where it repairs around the bad sector or
drive, and works until it returns to the safest state possible. If
DroboElite 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.
DroboElite is iSCSI SAN storage that manages
itself. There are no complex configuration screens, confounding
choices, or other complications that prevent so many other storage
devices from working out of the box. For companies that need simple,
consolidated storage for multiple servers but don’t want to deal with
the complexities of traditional SANs, DroboElite is the ideal solution.
Setup can be completed in a matter of minutes
and routine tasks such as expanding capacity are as simple as adding a
drive or replacing the smallest drive in the array. No need to back up
data or re-create a RAID array. DroboElite will automatically recognize
the additional capacity and make it immediately available to all Smart
Volumes and applications.
Create new volumes in seconds and
manage up to 255 volumes over time with ease. The innovative and
timesaving Smart Volume management technology integrated into DroboElite
allows volumes to pull storage from the common pool of drives rather
than a specific physical drive allocation, eliminating the need to
manage capacity at the volume level. Smart Volumes are also data aware,
allowing deleted data blocks to be returned to the common pool and
ensuring that volumes remain as efficient as possible over time.
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.
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 DroboElite so simple. The new drive
just provides additional places to store data.
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 them in the exact same
order. When you remove your disks from DroboElite, you can put them back
in any order you like.
