The Jetstor NAS 724UXD is a powerful dual-controller unified storage solution designed for high availability with features like active-active architecture, advanced data protection, and efficient resource utilization. It supports various RAID configurations, caters to both file-level and block-level I/O, and is optimized for environments requiring consistent data availability and scalability. Notable benefits include zero downtime, high storage efficiency through compression and thin provisioning, and robust performance for diverse application workloads.

4. Why Dual Controller NAS?
 2 Servers + 2 HBAs + OS license
+ SAN > JetStor NAS 724UXD
 2 NAS > JetStor NAS 724UXD
 Unified storage for business
processing application where high
performance SAN is not required
 Active – Active architecture
 Support ALUA, both controllers
can deliver IO at the same time
 Zero business downtime
 99.999% availability
 Hybrid storage. Support file-level and block-level I/O, structured and
unstructured data
 Thin provisioning, compression

5. Active-Active vs Active-Standby
Active – active Active – standby
Fast failover
Inter-process communication and heartbeat is achieved
using high speed bus on backplane protected by the
enclosure.
Slow failover
IPC and heartbeat is carried out using 1Gb Ethernet
external cable. It is slow and prone to external errors.
Efficiency
Support all RAID levels in the storage pool. Support
global namespace. Both controllers see the same HDD
configuration and storage pool.
Waste of resources
Limited to RAID 1 for HDD mirroring.
Because you need to set aside the same HDD capacity in
the passive system, it’s a waste of HDD capacity.
Performance scaling
Both controllers can deliver I/O and services at the same
time. IOPS can scale 1.5 times.
No performance scaling
Passive controller will not deliver I/O. The resource is
idle and wasted.
Consistent data after recovery
After recovery from controller failure, all disk data
remain intact and consistent.
Inconsistent data after recovery
After recovery from controller failure, the failed system
doesn’t have the latest disk data. Synchronization
process is needed and it is time consuming.

25. ZFS Benefits – Data Integrity
ZFS
EXT3
EXT4
Most SMB NAS use ext3/ext4 Journal file system, but any
unexpected shutdown may crash the Journal file system. This
causes some data loss or data inconsistency; the worse case will be
the file system crashing and whole data gone …
With JetStor NAS ZFS file system (that once belonged only to very
high-end products), there is 0% file system crash possibility and
always end-to-end protection of disk data consistency due to its
copy-on-write transactional model and self-healing architecture.

26. ZFS Benefits – Copy on Write
• All or nothing, always on-disk consistent
• Immune to power failure
