6. • The programming that controls the storage
is decoupled from the physical hardware
• Consists of the Storage Tier Only
• Emphasizes storage services such as
deduplication or replication, instead of
storage hardware
• A shared pool that runs on commodity
hardware
• Utilizes Policy Based Management
• Often referred to as Storage Virtualization
and is part of a bigger industry trend of
Software Defined Datacenter
Definition: What is Software Defined Storage
(SdS)

Local Physical Storage
Hosts
Storage Software can run on bare
metal or as a VM on a hypervisor host

7. • New Converged Infrastructure offering utilizing
Software Defined Storage
• Tight integration of x86 servers for compute
and storage, networking and virtualization in
all-in-one appliance. Packaging
• Integration of hypervisors and physical
infrastructure
• Simple Scale one unit/appliance at a time
• Simple deployment measured in hours
• Centralized management, intuitive UI
• Storage presentation via a distributed
filesystem or object store

12. HCI Architectures
Hypervisor
VM
Hypervisor Datastore
Storage Software
• Min of 2-3 nodes in a cluster providing storage
• Hardware to be similar with equivalent drive technology
• Scale 8 - hundreds of nodes (most support up to 64)
• Disks: Locally attached disks
o Hybrid: spinning disks and flash devices
o All-Flash: Flash devices only
• Network
o 1GB Ethernet OR
o 10GB Ethernet (preferred)
• “Witness” node acts as tie-breaker during availability
decisions
Storage Network

13. Data Tiering
• All data ingested goes through SSD caching tier
• SSD caching for read and write
• Allocation varies by vendor
• Writes are committed replicated and
acknowledged at the SSD cache tier
• Data is moved from SSD cache to spinning drives
• Time spent in cache is vendor specific
• Performance is impacted when SSD tier is
flooded with heavy IO
• Cache misses
• Some vendors also use Memory Caching
• Moving data closer to the processor
• More performance
VM
Write
Typical best practice is to
have a 10:1 ratio of HDD to
SSD capacity

14. • Data is protected by Replication or Erasure Coding
• Most SdS/HCI stacks use replication but more are switching
• Replication factor min of 2
• Cost is 50% of disk capacity
• Every block is written to min of 2 different nodes in the cluster
• Can survive a single node/device failure
• Higher device protection requires more replication
• RF3 reduces RAW disk capacity to 33%
• Requires min 5 nodes
HCI Data High Availability
VM
Replicate
Write IO

15. Network Considerations
• Many solutions require Multicast and IPv6 for node
discovery and scale out
• Multicast used for exchanging metadata and storage
network heartbeats
• Redundant 10Gb networking required for storage data
• Management/VM networking separate from storage
network
• Density solutions will require a large number of 10Gb
uplink ports
• Direct access to switches for low latency storage
communication
