Gen 5 Addresses Today’s Data Center Challenges
Virtualization &
Cloud
 Maximize VM density
 Enable mission-critical
and big I/O application
SLAs
 Eliminate I/O
bottlenecks
Flash/Cache
Databases
 Avoid I/O bottlenecks
for expensive app
acceleration
investments
 Fabric optimization for
new distributed flash
use cases like vMotion
 Enable data growth
and peak workloads
 Fastest response time
drives competitiveness
 Optimize for
virtualization and flash
cache
FC is the Most Trusted Fabric for the Enterprise SAN

IT Mandate: From Storage Capacity/Utilization
to Application Performance
$/GB
$/IOPS
Focused on Storage
Capacity
Virtualization/Cloud/Web
Need Application Performance &
Quality of Service
Disk & Traditional Fabric
Flash Tiers & Optimized Fabric
Traditional disk arrays and fabrics have
helped solve storage capacity problem
 Near-zero space snapshots
 Automatic de-duplication of redundant data
 High-performance dual-parity RAID systems
 Data cloning techniques
Application performance/SLAs are
now the focus
 Flash tiers + new Intel servers means
fabric I/O is now the bottleneck
 Shared/distributed storage use cases like
vMotion, HA/DR, & clustered apps require
fabric optimization
 Requires faster data access- operational
latency and IOPS for app response time
 Mixed virtualization/cloud workloads and
mission critical apps demand QoS, latency,
data integrity

Skyhawk RoCE
What is Remote Direct
Memory Management
(RDMA)?
What is RDMA over
Converged Ethernet
(RoCE)?
Benefits of Skyhawk-R
with RoCE

Ability to remotely manage memory enabling server to server data
movement directly between application memory without any CPU
involvement

A mechanism to provide this efficient data transfer with very low
latencies on Ethernet
Basically IB Over Ethernet (with PFC, etc.)
Classic Ethernet is a Best Effort Protocol



Delivers low latency for performance-critical and transaction intensive
applications

Better OPEX vs. Infiniband infrastructure which is requires a unique
fabric which is difficult to deploy and manage
RoCE is IB Over Existing Network Infrastructure
