A Historian Is…A storage repository for time-based information – a Database

But a Historian is much more than a database–A Historian stores process data - lots of it–A Historian lets you retrieve the process data – sensibly–A Historian Transforms the process data into Information

A complete system to enable you to make the best use of thisdata

Wonderware Historian does this, elegantly

“Store data at the resolution of your Process – Retrieve at theresolution of the Problem you are trying to Solve”

Historian Disk Sizing and Data StorageConsiderations• How important is the data?

• Is anyone in the organization going to require operating data that isolder than a month? Older than a year?

• How long can the system be off-line in the event of a componentfailure?

• What happens if the system stops storing data?

• What happens if stored data is lost as a result of a hard drive failure?

• Can the server equipment be taken off-line to perform repairs?

Storage Hardware

• SCSI/SAS/SATA drives configured using hardware RAID is optimum.

– RAID5/RAID1+0 – More Heads = Better!

– 10,000/15,000 RPM

– Design to use < 60% of available space

• Consider RAID1 SSD for Circular Storage

– RAID5/1+0 for Alternate Storage

• NTFS is the only officially supported file system for a productionSystem

• Enable file compression for the historical data storage locations - Circular,Alternate, Buffer, and Permanent.

Virtualization Example: Large System

• 32 cores over two R710 RackServers.

• Capacity enough to host forexample:

1 GR, 1HIST, 4 AOS’s, 4 RDS Servers,1 Info Server (11 Machines)

VM Cores and Memory Considerations

Cores and Memory• Spare Resources

– The host server should always have spare resources of 25% above what theguest machines require.

– For example, if a configuration with five nodes requires 20GB of RAM and 10CPUs, the host system should have 25GB of RAM and 13 CPUs. If this is notfeasible, choose the alternative closest to the 25% figure, but round up sothe host server has 32GB of RAM and 16 cores.

• Hyper-Threading

– Hyper-Threading Technology can be used to extend the amount of cores,but it does impact performance. An 8-core CPU will perform better than a 4-core CPU that is Hyper-Threading.

VM Storage Recommendations -1

• Plan for proper Storage. A best practice is to dedicate a local drive orvirtual drive on a Logical Unit Number (LUN) to each of the VMs beinghosted. We recommend SATA or higher interfaces.

• The host OS also should have a dedicated storage drive. A basicstorage topology would include:– Host storage

– VM storage for each VM

– A general disk large enough to hold snapshots, backups, and other content.It should not be used by the host or by a VM.

Storage Recommendations -2

• Recommended Storage Speed

– Boot times and VM performance are impacted both by storage bandwidthand storage speed.

• Faster is always better. Drives rated at 7200 rpm perform better than thoserated at 5400 rpm.

• Solid-state drives (SSDs) perform better than 7200-rpm drives.

– Keep in mind that multiple VMs attempting to boot from one hard drive willbe slow, and your performance willand your performance will significantly degradesignificantly degrade.

• Attempting to save on storage could well become more costly in the end.

Network ConsiderationsNetworking is as important as any other component for the

overall performance of the system.

Recommended Networking for Virtualization

• If virtualization is your only requirement, your networktopology could include the following elements:

– Plant network

– Storage network

– Virtualization network.

• A best practice is to establish, on every node, an internal-only Static Virtual Network. In the event that the host andthe guest VMs become disconnected from the outside world,you will still be able to communicate through an RDP sessionindependent of external network connectivity.

Virtual Host Recommendations - Review

• Do NOT use Shared Resources

– Pre-Allocate dedicated Memory for every VM

– Pre-allocated Cores for every VM

– Separate Drive or R/W heads for every VM

• SAS, FibreChannel SAN

– Flash Memory for VMHost (ESX/vSphere/Win2K8R2)

– Use Solid State Drives for Circular Storage

• HP Servers• 1GB Flash Backed Write Cache is HIGHLY recommended

It’s About Time (Stamps)

• Timestamps are propagated from IO/DA Source

– Can be several hops removed from Historian

• Pick One!!

– Domain Time Synch (Windows Time Service)

– W32TM

– Net Time

– NTP (Network Time Protocol)

– 3rd Party

• VM Technology can affect Server Time Drift

– vSphere5 is currently better than Hyper-V (2K8R2)

Runtime DB Maintenance

• The Runtime DB size is not affected by the amount of history data.

• General settings let you purge event and summary data.

• You need to manually purge the change log (ModLogTracking).

• Avoid creating custom tables in the Runtime DB.
