Highlights
■■ Easily configure, manage, and
This flexible, cost effective platform allows you to scale seamlessly as your capacity, performance and monitor your SnapServer(s) from
number of SnapServers grow. Because SnapServers attach directly to the network, they install in minutes anywhere in the world
and are easily deployed without application downtime. You can consolidate systems by creating file- and
block-level volumes on a single device. And centralized management combined with a comprehensive set ■■ Effortlessly move data to your

FEATURE FUNCTION BENEFIT
NTP Support Provides time synchronization services for all devices on Allows you to quickly and easily synchronize system time for all
the network. The SnapServer can act as an NTP server NTP-compatible devices on your network
or client
Configuration Backup/Restore Creates a backup image of all key SnapServer Gives you the ability to quickly restore your SnapServer in the
configuration information event of a disaster as well as clone a particular configuration to
multiple systems
Ethernet Teaming Logically groups Ethernet ports together in load balance Increase bandwidth and provide redundancy by bonding Ethernet
and/or failover modes ports together
DHCP Automatically assigns an IP address to the SnapServer Makes connecting to a network quick and easy
when it’s connected to a network (Note: the IP address
can also be set manually)
UPS Support w/Controlled Gracefully shuts down the SnapServer in the event that a Protects data during extended power outages and brings the
Shutdown and Restart power outage lasts longer than the battery on the UPS. SnapServer back online automatically as soon as power becomes
Automatically restarts the SnapServer when power is restored available
Wake-On-LAN Allows the SnapServer to be powered-on remotely over You do not need to be physically present at the site where your
the network SnapServer is located to power it on
DATA PROTECTION
RAID Groups hard drives together into a logical storage pool Guards data if drives fail and increases performance by
aggregating drive throughput
Snapshots Creates incremental, point-in-time copies of a volume or Enables you to create frequent, space-efficient backups with no
LUN disruption to data traffic
Snap EDR™ Provides multi-directional, WAN-optimized replication for Easily replicate data between two or more SnapServers for file
SnapServer systems sharing and disaster recovery
Integrated Backup to Disk, Integration with leading 3rd party backup applications* / Allows you to back up your SnapServer directly to a disk, VTL or
VTL or Tape Support for SCSI or SAS-connected tape devices tape device
