Sensor calibration

• Producer support – Calibration hardware level support (sometimes);

– Calibration protocols and tables (anytime).

• EE experts– Fine tune of existing calibration data and protocols;

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

– Fine tune of existing calibration data and protocols;

– Sometime development from scratch of calibration protocols (even hardware supplementary equipment) and are required.

• Minimal standards to comply: – ISO/IEC 17025, ISO 9001.

• Regarding sensor communications:

– only difficulties - RS232 which have to comply with standards: DIN VDE 100, DIN VDE800, DIN43629 and DIN EN 50289.

DAQ Software Quality Assurance

• Tricky / difficult business!!

• Provided partial or total by hardware producer (e.g. Nat Inst., NI see site: www.ni.com.):– Usually meet the quality assurance standards because in the

worst case they give detailed methodologies about how the job can be done.

• Developed on site by EE Expert

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

• Developed on site by EE Expert– Problems - in case of required supplementary certification, if

needed!

• Minimal Required Compliance wit Standards:

Suitable Datacenter Location

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

Minimal standards: TIA942, ASHRAE data books, the ones

of Uptime Institute – TUI, Telcordia standards like GR-63-

CORE and European standard EN50173-5.

Datacenter room distribution

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

- The TIA approach - supplemented by a special room for control,acquisition command & control equipment.- Special room for telepresence was added.- Data center - needs of specifications between tier one and tier two fromTIA 942 standard.

Page 12: On Quality Enhancement in Seismic Testing Laboratories ... · On Quality Enhancement in Seismic Testing Laboratories based on Efficient IT Infrastructure Deployment SERIES WS WP3

Q requirements for

Datacenter Design (1) • The racks standard shall be 42U with compliance on

Telcore GR-63-CORE standards.

• The design of data center has two constraints related to the seismic experiments to be done in the future.

• During the operational phase the equipment needed for experiments are as well exposed to relative high

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

experiments are as well exposed to relative high vibration characterized, by high frequencies and important peak ground accelerations (PGA).

• The standard used for datacenters design considers that a major seismic event (real one) can be afforded once in a lifetime, considered around 20 years.

• In the present time, there are insufficient data regarding fully equipped datacenter behavior in case of occurrence of a major seismic event.

Page 13: On Quality Enhancement in Seismic Testing Laboratories ... · On Quality Enhancement in Seismic Testing Laboratories based on Efficient IT Infrastructure Deployment SERIES WS WP3

Q requirements for

Datacenter Design(2)• As an example, the Kobe earthquake had unexpected

and unpleasant effects on different datacenters, located around.

• The weak point seems to be especially at level of the raised technical floors of the construction [Rasmussen, 2010].

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

2010].

• Taking into account this consideration it is recommended to design a relatively high dense IT infrastructure in datacenters.

• After conducting surveillance on existent solutions on the market we can conclude that the rack producers tests done on a single rack, excited by a signal for real earthquake are not sufficient, since it should be considered the test of a fully deployed datacenter.

Page 14: On Quality Enhancement in Seismic Testing Laboratories ... · On Quality Enhancement in Seismic Testing Laboratories based on Efficient IT Infrastructure Deployment SERIES WS WP3

Q requirements for

Datacenter Design (3)

• For design of datacenter some of the following

solutions are to be considered:

– The use of special design for datacenter building

which have the role to absorb the majority of seismic

effects (like using inertial dumpers, rubber based

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

effects (like using inertial dumpers, rubber based

foundation or other suitable approach)

– The use of ceiling cabling to avoid the raised floor and

anchor racks directly in the foundation

– The considerations of technological floor re-design

and racks links to them, in order to increase the

seismic resistance of the whole structure.

Page 15: On Quality Enhancement in Seismic Testing Laboratories ... · On Quality Enhancement in Seismic Testing Laboratories based on Efficient IT Infrastructure Deployment SERIES WS WP3

Q requirements for

Datacenter (4)

• The other problems like fire, water flood,

humidity, gases and temperature are well

specified in standard. The selected solutions use

the tier two specifications regarding threats from

TIA 942.

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

TIA 942.

• For cabling - EU standard EN50173-5 must be

used.

• For first two zones in network trunk distribution

unimode fiber optic are recommended; GR-326

standard may be used.

Page 16: On Quality Enhancement in Seismic Testing Laboratories ... · On Quality Enhancement in Seismic Testing Laboratories based on Efficient IT Infrastructure Deployment SERIES WS WP3

Q requirements for

Datacenter (5)

• Regarding the datacenter availability there are some redundancy measures, specific at least for tier two, token like ups, ups, N+1 power supply and so on.

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

N+1 power supply and so on.

• This are obtained by conforming to ISO 9001, or TIA 942 and ASHRAM documents a.s.o.

Some final remarks

• The complexity of required IT infrastructure for

EE laboratories need the to comply with the

specific standards previously presented.

• The role of IT will increase in the years to came

at the EE laboratories level.

SERIES WS WP3 NA2, 2.09.2010, Ohrid MK

at the EE laboratories level.

• The existing standards referring to requirements

to be fulfilled by datacenter under located in

seismic active area should be examined and

may be changed (see Kobe earthquake effects

on datacenter example).
