VIA ETHERNET
The LaCie 5big Network 2 offers professional, reliable, central
storage for instantly storing, sharing, and backing up from any PC or
Mac® on your network. Up to 10TB of storage capacity in five bays
expandable with its two USB and two eSATA ports. You can also
take advantage of its two Ethernet ports to do link aggregation and
get twice the performance of single Gigabit Ethernet connection.
Recommended for networks of up to 300 users, the 5big Network 2
is the right solution for IT environments looking for high capacity and
high transfer speed rates.

RAID Protection
Thanks to the secure RAID modes, including RAID 5 and RAID 6,
the 5big Network 2 enables you to keep data access even if one
disk fails. The hot-swappable disk trays** even allow maintenance
without affecting your workflow. “Spare” modes allow a second
level of protection; a sort of “automatic maintenance” that will
immediately start rebuilding the RAID protection in case of a disk
failure. And with room for five disks, the 5big offers more capacity
than four-disk solutions in almost every RAID mode. Extra spare
disks are available as an option for immediate replacement.

A Complete Backup Solution
Get extra security and increase data portability by backing up
your LaCie 5big Network 2—on your own schedule—to an
external hard drive through its USB and eSATA ports using the
built-in copy system. The 5big Network 2 also comes with three
client licenses for Genie® Backup Manager Pro™ for Windows®
and three licenses for Intego® Backup Manager Pro™ for Mac
to install on each PC or Mac for client backups to the NAS. This
software lets you reliably and efficiently back up your documents,
emails, settings, or other digital assets; it supports compressed,
encrypted, or image backups and implements a computer
recovery function in case of a system failure.
• Fast access to your NAS—Performance up to 70MB/s
• RAID 5 or RAID 6 (hot-swap) modes in case of disk failure
• Failover and load balancing options using two LAN interfaces

You can set up an iSCSI share of your 5big Network 2 and
mount it as a local share on your computer in the same way
that external hard drives are mounted when connecting to your
PC/Mac. An iSCSI connection will bring you performance and
flexibility for professional applications. You can use the 5big
Network 2 as final backup destination of any server integrating
an iSCSI initiator.

Simple, User-Friendly Administration
With the 5big Network 2’s new widget-like dynamic web interface,
administration is easy, convenient and secure. Thanks to the
its DHCP and Apipa support, network configuration is fast and
automatic. The product integrates easily with existing Windows
domains using Active Directory and it allows user, groups, share
and quota management. Access to administration page and
shares is easy using LaCie Network Assistant; and, on top of that,
it can provide its administrator notifications via email of events like
backup, disk failure, high temperature, etc.

Eco Management
The LaCie 5big Network 2 helps you to reduce power consumption
by switching to idle mode (where the disk spins off) after a
determined inactivity time. Also, you can schedule a deep sleep
on/off mode according your needs. Thanks to the Wake-on-LAN
feature, it can be switched back to operating mode from the client
side. The 5big Network 2 also integrates UPS support *** through its
USB ports to ensure proper shutdown in case of power failure. On
top of that, its exclusive sturdy and elegant aluminum design makes
it your ecological partner; it’s recyclable and ROHS-compliant.
