Datasheet

The Business Series Turbo NAS has a scalable design that grows with
the data-hungry businesses. Volumes are expandable via the QNAP
RAID expansion enclosures, REXP-1200U-RP and REXP-1600U-RP.
Multiple RAID expansion enclosures can be cascaded to provide
over 400 TB raw capacity.
Plug and Use, Seamless Capacity Expansion
With the plug-and-use design, the RAID expansion enclosure delivers
a fast way to easily scale up storage capacity of the Turbo NAS. Simply
connect a RAID expansion enclosure to a Turbo NAS and power it on, the
Turbo NAS will detect the hard drives in the enclosure as newly installed
local drives. With the Storage Manager in the QTS 4.0 intelligent operating
system, the IT administrators can online expand an existing volume on the
NAS without service interruption. Multiple RAID expansion enclosures can
also be cascaded to provide massive capacity. The status and health of the
enclosures can be monitored via the web-based management interface of
the Turbo NAS.
High Density, High Efficiency and High Scalability
Two RAID expansion enclosure models are available. The REXP-1200U-RP
supports 12 SAS/SATA 6Gbps hard drives and SSD in 2U rack space,
providing up to 36TB raw capacity. The REXP-1600U-RP supports
16 hard drives and 48TB raw capacity in 3U rack space. These RAID
expansion enclosure units provide two SAS wide ports (IN port and
OUT port) for host connectivity and daisy chain respectively. Each SAS
wide port combines four SAS channels, with each supporting 6Gbps
full duplex speed. The maximum bandwidth per host connection is
24Gbps, which delivers unprecedented performance when daisy-
chaining multiple RAID expansion enclosures.
QNAP Flexible Volume provides a more secure and flexible way to
store and manage the NAS data. This next generation volume offers
powerful features such as storage pooling with multiple RAID, thin-
provisioned volume with space reclamation, and online capacity
expansion.
Secured Storage Pool for over 100-disk Deployment
To ensure the safety of valuable business data, QNAP Flexible Volume
provides a secured way to deploy a large volume. The logical volume
is allocated from a Storage Pool, which is composed of multiple RAID
Groups to gain higher redundancy and reduce the risk of data crash
from bad hard drives since the data is dispersed throughout multiple
RAID arrays.
Block-based iSCSI LUN
In addition to storing data, the QNAP Flexible Volume can be utilized as
an iSCSI LUN at the same time. The block-based iSCSI LUN provides less
overhead which improves the over read/write performance. The block-
based iSCSI LUN takes advantages of Flexible Volume such as thin-
provisioning LUN with space reclamation and online capacity expansion.
Online Capacity Expansion
Increase the capacity size of the LUNs, volumes, and storage pools on
the fly. The Turbo NAS allows you to add more hard drives to increase
the storage capacity of the storage pool on demand. The LUN and
volumes can also be expanded online without interrupting the services.
Thin-provisioned Volume
Pre-allocate storage to give the appearance of having more capacity
than actually available. This allows you to consume storage on demand
as data is written to disk, instead of having capacity ahead of time.
Space Reclamation
Space reclamation complements thin provisioning so storage can be
freed and used for other NAS applications. Normally when data is
deleted in a Space, the storage capacity cannot be transferred back
to the overall storage pool. But with space reclamation, space can be
reclaimed and released back to the overall storage pool. This provides a
much more efficient space usage.
Alert for Volume/LUN Threshold
An alert can be created once a LUN or volume reaches a particular
threshold size with email and SMS notifications. This prevents the
storage or volume from running out of space and the administrator can
provision a new storage or expand an existing volume before a critical
out of space.
