VCE VxRack™ SYSTEM is based on ScaleIO
• Modular design
– Simple form factor appliance (2RU houses 4 dense or 1 regular node)
– Traditional compute (CPU & RAM) to run application workloads
• Local storage presented as shared, software defined storage array
– Flash drives as ScaleIO caching or performance storage pools
– Hard drives for scalable storage pools

Extensible scale
 Add nodes to incrementally scale the infrastructure (up to 1,000’s of ScaleIO nodes)
 ScaleIO automatically balances storage resources
 Node types (performance, hybrid, storage only) can be mixed for non-linear scaling or resources
 Simplifies customer hardware refresh cycles (add new nodes, relocate workloads, remove legacy nodes)

Applications and storage share the same physical node
 All nodes are a mix of VCE VxRack™ System 1032 node types
relevant to application workload i.e., dense compute, hybrid,
dense storage
 Adding more servers increases the cluster-wide storage and
compute resources
 Enables non-disruptive rolling hardware refresh for in-line
lifecycle management
Option1: Hyper-converge
Application and storage servers installed in separate
hardware tiers
 1st tier predominantly dense compute and hybrid node
 2nd tier predominantly hybrid and dense storage
 Aligned to maintain application and technology
support teams
 Discrete storage/network/server orgs
 Efficient parallelism and no single points of failure
between apps and storage
Option 2: Two-layered
A combination of option 1 and 2 is feasible

VxRack System Nomenclature
VxRack System resources are presented in ‘nodes’
 VxRack System node = assembly of CPU, Memory, Storage resources
VxRack System 1032 nodes are sold in 2RU* ‘enclosures’
 Dense compute enclosure = 4 nodes
 Dense storage / storage only enclosure = 1 node
Dense compute enclosures initially sold fully populated
 4 nodes, must be all the same configuration (no mix and match)
 Long term goal is to enable configure-to-order

VxRack – Massive ScaleOUT
http://www.esg-global.com/lab-reports/esg-lab-spotlight-emc-scaleio-proven-performance-
and-scalability/
« The performance results clearly show that ScaleIO lives up to its name and
continues to scale, even when nodes are populated with extremely fast storage
devices. ESG Lab has no doubt that a ScaleIO cluster will continue to scale in both
capacity and performance as nodes are added to hundreds or even thousands of
nodes. »

 Base configuration is a single rack
 Minimum configuration of 3 x enclosures
 3 is minimum requirement for ScaleIO SDS deployment
 Can be any mix of dense compute/storage , storage only
 Management switch is Nexus3172
 Connects to 1GB IPMI port on every enclosure (Out of Band)
 VxRack System Controller runs M&O components
 Lightweight ‘hardware bootstrap’ vs traditional Vblock System AMP
 1RU server.
 ‘Top of Rack’ switches are Nexus 3132 or 3164 switches
 Dense compute = 16x10GB per enclosure (4 NICs/Node)
 Dense storage/storage only = up to 4x10GB per enclosure
 Nexus 31xx provide inter-node connectivity (10GB) and also customer network uplink
(10GB or 40GB)
 Maximum of 108 nodes
 (exact rack count depends on type of enclosures used)
 # of nodes is dependent on network topology

Network Topology – Switch selection
LAN switching uses either the Cisco Nexus 3132Q-X Switch, the Cisco Nexus 3164Q Switch
or the Cisco Nexus 9332PQ Switch.
The default non-ACI (Application Centric Infrastructure) network design contains a pair of connected Cisco
Nexus 3132Q-X or Cisco Nexus 3164Q access layer switches which support a maximum of 108 nodes.
Cisco 3132Q – 32x 40G QSFP+ (or 128x 10G w/ breakout cable)
Cisco 3164Q – 64x 40G QSFP+ (or 256x 10G w/ breakout cable)
Cisco 9332PQ – 32x 40G QSFP+ (or 256x 10G with breakout cable)

23. © Copyright 2015 EMC Corporation. All rights reserved
Network Topology - deployment
• When density exceeds 108 nodes, the switch pairs can be bundled together and attached to a pair of
Cisco Nexus 9332PQ leaf switches, supporting up to 216 nodes.
• When density exceeds 216 nodes, the 9332PQ switches can be attached into the Vscale spine to
allow for large-scale deployments.
Vscale
Spine

24. © Copyright 2015 EMC Corporation. All rights reserved
Network Topology
ACI environments contain nodes connected directly into the 9332PQ leaf switches which
support a maximum of 48 nodes.
• When density exceeds 48 nodes, the 9332PQ switches can be attached into the Vscale
Spine to allow for large scale deployments.
While this scaling introduces multiple physical VxRack System units they can be configured
into a single logical VxRack System Cluster via these 9332PQ network connections and
the VSAN will span all the nodes in a network grouping.
Note: SDN is not supported in the initial release.
The compute layer connects to the Ethernet component of the network layer. The
southbound fabric interconnects connect to the Cisco Nexus switches in the Ethernet network
through 10GbE port channels.
