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
Active-Active vs Active-StandbyActive – active Active – standby
Fast failoverInter-process communication and heartbeat is achieved using high speed bus on backplane protected by the enclosure.
Slow failoverIPC and heartbeat is carried out using 1Gb Ethernet external cable. It is slow and prone to external errors.
EfficiencySupport all RAID levels in the storage pool. Support global namespace. Both controllers see the same HDD configuration and storage pool.
Waste of resourcesLimited 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 scalingBoth controllers can deliver I/O and services at the same time. IOPS can scale 1.5 times.
No performance scalingPassive controller will not deliver I/O. The resource is idle and wasted.
Consistent data after recoveryAfter recovery from controller failure, all disk data remain intact and consistent.
Inconsistent data after recoveryAfter recovery from controller failure, the failed system doesn’t have the latest disk data. Synchronization process is needed and it is time consuming.

ZFS Benefits – Break Bottlenecks
Storage size is ever- increasing
Storage efficiency is low
Data integrity and data protection become
more critical
Data management costs are high

ZFS Benefits - Highlights• More than just another FS : file system + volume manager + RAID
controller all in one• Immense scalability : 128bit address space• End-to-end data integrity
– Everything is copy on write, always on disk consistent– Everything is transactional– Everything is checksumed, no silent corruption, no bad metadata– Enhanced data protection : snapshot, replication, pool scrubbing
• Storage efficiency– Thin provisioning, compression
• Simple administration
ZFS Benefits – Data Integrity
ZFS
EXT3EXT4
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.
ZFS Benefits – Copy on Write
• All or nothing, always on-disk consistent• Immune to power failure
ZFS Benefits – Silent Corruption

Thin Provisioning
Space reclaim is supported automatically in the background to recycle unused blocks to the storage pool.
Compression• Block-level, inline real time
operation• LZJB algorithm : lossless and
good balance between speed and efficiency
• Both files and LUNs can be compressed
• Efficient and almost no performance impact

File Sharing Center
Powerful Network Settings• Supports all 7 aggregation types
(round-robin, active-backup, trunking,
broadcast, LACP, TLB, ALB)• Supports VLAN• Supports jumbo frame (9000 bytes)• Cluster IP for SMB and NFS• Policy-based IP filtering
Fail-Safe Networking
• Network ports from both controllers are mirrored to form cluster IP for file services (SMB and NFS)
• A cluster IP always contains two paths (redundant)
• Any path in the cluster IP fails. I/O will automatically switch to another path transparently.

Directory Services• Supports Windows Active Directory • Supports Lightweight Directory Access Protocol (LDAP)
UnifiedAUTH is Simple• All data services (CIFS, FTP, AFP, iSCSI, webDAV) adopt the same set of
account & password for authentication.• No more – forgot password?
