the pendulum swings back: converged and hyperconverged environments

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

� 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

#ibmedge

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
