򐂰 MetroCluster:
– Offers an integrated high-availability and disaster-recovery solution for campus and
metro-area deployments.
– Ensures high data availability when a site failure occurs.
– Supports Fibre Channel attached storage with SAN Fibre Channel switch, SAS
attached storage with Fibre Channel -SAS bridge, and Gateway storage with SAN
Fibre Channel switch.
򐂰 MultiStore:
– Partitions a storage system into multiple virtual storage appliances.
– Enables secure consolidation of multiple domains and controllers.
򐂰 NearStore (near-line):
– Increases the maximum number of concurrent data streams (per storage controller).
– Enhances backup, data protection, and disaster preparedness by increasing the
number of concurrent data streams between two N series systems.
򐂰 OnCommand:
– Enables the consolidation and simplification of shared IT storage management by
providing common management services, integration, security, and role-based access
controls, which delivers greater flexibility and efficiency.
– Manages multiple N series systems from a single administrative console.
– Speeds deployment and consolidated management of multiple N series systems.
򐂰 Flash Cache (Performance Acceleration Module):
– Improves throughput and reduces latency for file services and other random
read-intensive workloads.
– Offers power savings by using less power than adding more disk drives to optimize
performance.
򐂰 RAID-DP:
– Offers double parity bit RAID protection (N series RAID 6 implementation).
– Protects against data loss because of double disk failures and media bit errors that
occur during drive rebuild processes.
򐂰 SecureAdmin:
– Authenticates the administrative user and the N series system, which creates a secure,
direct communication link to the N series system.
– Protects administrative logins, passwords, and session commands from cleartext
snooping by replacing RSH and Telnet with the encrypted SSH protocol.

Single Mailbox Recovery for Exchange (SMBR):
– Enables the recovery of a single mailbox from a Microsoft Exchange Information Store.
– Extracts a single mailbox or email directly in minutes with SMBR, compared to hours
with traditional methods. This process eliminates the need for staff-intensive, complex,
and time-consuming Exchange server and mailbox recovery.
򐂰 SnapDrive:
– Provides host-based data management of N series storage from Microsoft Windows,
UNIX, and Linux servers.
– Simplifies host-consistent Snapshot copy creation and automates error-free restores.
