Data Mobility and
Migration
Replication
Replicates with other SC Series
arrays*
Synchronous/Asynchronous via FC
or iSCSI
Per-volume QoS bandwidth
prioritization
Target/source relationships may
be one-to-many or many-to-one
Supports all SC data services on
source and target volumes
Change replication types and
topologies on demand
Supports cross-platform
replication with PS
Series/EqualLogic arrays (either
direction)
Volume mobility
Live Migrate (included
in base product) enables
host-transparent data movement
among arrays; see also
Federation section
Federated multi-array
systems
Live Migrate (included in base
product) enables
host-transparent movement of
volumes among arrays
Snapshots maintained/preserved
during migration
Thin Import
Space-efficient, non-disruptive
data migration from PS Series
(EqualLogic) arrays
Thin Clones
Clone standalone
volumes with zero duplication of
data
Clones maintain independent
snapshots and replication
Ideal for VDI, test/dev, other
applications that require
discrete instances of common
data
More efficient than dedupe for
database copies

tier
RAID support
RAID 0, 1, 5, 6, RAID
10, and RAID 10 DM (Dual
Mirror); any combination of RAID
levels can exist on a single
array
RAID tiering
Auto-provisions and dynamically
restripes multiple RAID levels
on the same tier; no need to
pre-allocate RAID groups
Thin provisioning
Active by default on
all volumes, operates at full
performance across all features
Thin snapshots
Records changes only, snapshots
auto-migrate to lower-cost
storage
Intelligent
deduplication and compression
Selectable option per volume on
SSD and/or HDD tiers in hybrid
configurations
Compression-only option also
available on any configuration
HDD optimization
FastTrack moves frequently
accessed data to outer tracks
for quicker response times
Data Protection
Data Protection,
Disaster Recovery, Security
Business continuity
Live Volume
bi-directional auto-failover,
auto-repair*
Continuous operations, disaster
recovery, disaster avoidance

replication options with Live
Volume Managed Replication*
Zero RTO/RPO with customizable
site failover SLAs per volume
VMware Metro Stretch Cluster
support

Distributed sparing
No dedicated hot spares
required, all drives available
for I/O
Thin snapshots
