1365The Pendulum Swings Back –Understanding Converged and Hyperconverged EnvironmentsTony Pearson, IBM
Master Inventor and Senior Engineer
#ibmedge
In the early days of IT, storage was internal to its server, over time, storage outgrew its container, and we started have externally attached storage, and benefits like RAID and clustered servers for high availability. Then, SANs, LANs and WANs took the main stage, allowing for greater connectivity and distance.
But now, it seems the pendulum is swinging back with converged and hyperconverged systems.
This session will provide the motivations, advantages and disadvantages of these new configurations.

The Pendulum Swings on Infrastructure Design
Internal Storage
• Personal Information Managers (PIM)
• Mainframe
• AS/400
Advantages
� Simple, self-contained
Disadvantages
• Simple, self-contained
• Scalability limited to what can fit inside the hardware container
• Single Point of Failure (SPOF) (unless you keep 2 or more copies of data across independent systems)
• Backups, Security and other Policy enforcement is done on a system-by-system basis individually

#ibmedge
The Pendulum Swings to External Storage
External Storage
• Mainframe
• AS/400
• Linux, UNIX, Windows
Advantages
� Two or more servers can directly attach to external storage
� High-availability clusters
� RAID for data protection and performance
� Shared Cache
� More room for storage growth
� Centralize features, snapshots and tape drives for backups
Disadvantages
• Scalability limited to number of hosts attached
• Limited distance for external cables

The Pendulum Swings to Networked Storage
SAN
LAN
Advantages
� Many more hosts can be attached
� Greater distances enables Disaster Recovery
� Fewer, larger systems like Tape Libraries easier to manage
Disadvantages
• SANs and LANs requires different skill sets
• OS-specific and device-specific management tools
Networked Storage
• SAN and NAS attached flash, disk and tape systems
• IBM Spectrum Scale
• IBM Spectrum Virtualize and SAN Volume Controller

The Problem: Islands of Volume, File and Object data
Volume-level Storage� OS-specific file systems on direct -attach
or SAN-based devices
� Sharing requires file transfers
� Provides “Context” for Analytics of Social and Mobile transactions

across social networks

� HDFS requires transfer (ingest) from other sources

� Servers can now hold sufficient Flash and Disk capacity
� Easy to re-purpose servers as needed
Disadvantages
• SPOF requires 2 or more copies across independent servers
• High-speed Ethernet or InfiniBand network for connectivity
• Distance and Scalability issues on some deployments
Hyperconverged Systems
• Storage-richservers with software to connect across other servers
27

VMware Virtual SAN (VSAN)
• VSAN cluster consists of 2-64 VMware ESXi hosts
• At least 2 must have disk groups
• Each host has 0 to 5 disk groups• Disk Group is 1 SSD plus 1-7 HDD• 70% SSD as Read cache• 30% SSD as Write cache
• IP Network used to make three copies (replication) of data
• L2 Multicast required• 1GbE can be used• Jumbo Frames and 10GbE
recommended
• Only members in the cluster can access the data
