Why is VPLEX Unique?
VPLEX enables users to:
– Have the exact SAME information
▪ In two separate locations
• Accessible at the SAME time from both locations

VPLEX & AccessAnywhereTM
Enabled by Distributed Virtual Volumes
•
Provides shared storage, concurrently
read and write accessible, with the
same storage identifiers, across sites.
•
Supports all major EMC and Non-EMC FC
storage platforms.
•
Supported by nearly all open systems
application clustering technologies.
•
•
Simplifies High Availability and Disaster
Recovery design and operations.
Enables 100% storage availability.

 With VPLEX, two VNX arrays can be
configured to provide full online
redundancy for each other within or
across sites.
 Data remains available and
online, even if a whole array fails.

Introducing VPLEX into Your Environment
Encapsulation Method
Host
Data-in-Place Migration
Minimal
Disruption
VPLEX
(No data copy)
1. Connect to VPLEX and mask volumes
2. Import volumes into VPLEX (1:1)
3. Unmask old path
4. Present volumes from VPLEX
5. Remount volumes

VPLEX for Migrations
Limit Risk – Less complexity, fully reversible
Save Money – Lower or eliminate services costs
Faster Time to Value – Leverage new arrays in days
Powerful TCO – All future tech refreshes are FREE!
No Downtime – Non-disruptive process

Traditional VMware DR Active-Passive Solution
Disaster Recovery
Traditional Active – Passive Solution
 Manual intervention to initiate
failover in the event of an outage
HA
SRM
 Dynamic job relocation (vMotion)
only possible within the datacenter
 Site failure or major infrastructure
outage results in application
disruption
 Double the capacity, but only the
I/O utilization of one array
 Additional, inaccessible servers
required at DR site

VNX with VPLEX for VMware– Active/Active Solution
Continuous Availability, Next Generation DR, Load Balancing
Active – Active Solution
 vMotion across datacenters for nondisruptive load balancing, maintenance,
and workload re-location
 Automatic failover and restart between
the sites using VMware HA - no manual
intervention
 The loss of a storage array or requirement
for planned downtime does not result in
ANY application interruption

What’s new with VPLEX 5.2
Extends VMware Integration:
Support of hardware acceleration
using VAAI Block Zero
Virtual Volume Expansion: Expand
local and distributed virtual volumes
non-disruptively
Larger and adjustable IO Block
sizes: Increase VPLEX performance
and network utilisation rates by
increasing the IO Block sizes from
128KB up to 1MB

VPLEX frame-based licensing with
VNX: This new licensing option
makes VPLEX easier to order with
VNX arrays
Free Migration License: Unlimited
capacity, 180 day license for tech
refresh
SRM Suite VPLEX Report Pack:
Delivers health reporting for the
VPLEX directors: Frontend and
Backend IOPS, bandwidth and
status; Virtual Volume health; locality,
read/write IOPS and status; storage
volumes health; capacity planning
and trending; performance metrics

VNX with VPLEX for Continuous Operations
Improved Availability, Mobility And Accessibility
VPLEX allows
customers to never
have planned or
unplanned
downtime again –
all data is
continuously
available
© Copyright 2013 EMC Corporation. All rights reserved.
 Increased availability
 Zero RTO and Zero RPO over distance
 Full utilization of resources at both sites
 Accelerated tech refresh
 Ride through component or VNX array
failures
 Active-active data access
 Increase resource utilization
15
Autostandby
 Currently in PowerPath, if you do not want a
path used, you can set it to standby
 Autostandby adds a trigger that causes a
path to be put in autostandby mode
– Behaves just like standby
– User set standby always has precedence
 Use cases
– Detect a flaky path
– Detect groups of paths connected to local
and remote array controllers in a federation
