Perfect Storage Trio: Tiered Storage, Application-Based
Partitioning and Network Trac Distribution
Comprehensive storage combination
A
Use PCIe NVMe as the read cache and SSD+SATA
HDD as the storage pool for Qtier
B
Use M.2 as the read cache and SSD+SATA HDD
as the storage pool for Qtier
C
Use SSD as the read/write cache and SATA HDD
for general purpose storage pool
Application scenario: Ultra-high speed 24/7 accelerated
performance with medium amount of data variation,
coupled with instantaneous large number of
connections; typical example: news website database.
Application scenario: aordable 24/7 accelerated
performance.
Application scenario: simultaneous accelerated
read and write performance and ideal for large data
volumes and huge changes in content that require a
fast response to hot data movement; typical example:
video editing.

Application-based Partitioning Network Traffic Distribution
QTS provides diverse applications and each application has different
performance requirements. For example, to ensure the integrity of recordings,
Surveillance Station requires higher-priority access to storage media, while
normal transmission speeds are sufficient for file sharing. However, when
multiple applications are running on the same storage media, the required
throughput level cannot be guaranteed as the storage media is busy handling
I/O requests from all of them. The TVS-x82 series supports three dierent types
of storage media: M.2, SSD and SATA hard drives and they can be congured
as independent partitions for dierent applications, ensuring the throughput
level for each application.
Network bandwidth essentially dictates the I/O performance for all NAS
services. If every application and service uses the same network interface, the
required bandwidth cannot be guaranteed for important applications and
applications that consume large bandwidth will probably use most of the
available bandwidth. For example, if the surveillance system, virtual machine,
and file sharing service all use the same network interface, the surveillance
system is likely to drop frames. Therefore, network trac distribution becomes
extremely important. With four 1GbE NIC and two 10GbE NICs, the TVS-x82
series allows applications to use dedicated interfaces to meet network trac
distribution requirements. Network interfaces can also be easily managed with
the Network & Virtual Switch app.
