Operating systems for servers

• Choosing an operating system

- What knowledge is in-house?

- Customer SOE requirements?

- Are your chosen parts supported?

• Things to remember

- Servers often require licenses

- Must be managed properly



ww

Failure pre-warning

• Hard drives will fail!

- S.M.A.R.T. monitoring

- Built in notification of impending failure

• Storage Failure Detection

- Built in to camera

- Post-failure only



ww

Warranty can save your backside

• Standard consumer product warranty

- 1 year, return to base

- No footage recovery options

• Enterprise warranties

- Multi-year, on-site or direct shipped parts

- No risk to footage security

- Footage not lost if recoverable

Allocating the available space

• RAID reduces space - check actual remaining

• NEVER allocate every last megabyte!

• Allow approx. 10% space as free

om


Stress testing storage devices

• 2 tests - Continuous & Event based

- All tests performed at QXGA, full frame rate

• Run for 2-3 months at full load

• When drives are 100% full:

- MxCC synchronous playback

- Search and export of footage

Optimise MxCC access to recordings

• Set MxCC access direct to storage medium

• User “via Camera” only when absolutely necessary

- SD card is viacamera only
