1. Minimum configuration means 1 x 85W-6C CPU (E5-2609 v3), 1 x 4GB DIMM, 1 x 2.5” SATA SSD, 1 x 495W PSU and no PCI cards.
2. Typical configuration means 2 x 105W-10C CPU (E5-2660 v3), 8 x 8GB DIMM, 4 x 2.5” 10K SAS HDD, 2 x 750W PSU and H730 miniPERC
cards.
3. Feature-rich configuration means 2 x 135W-12C CPU (E5-2690 v3), 16 x 16GB DIMM, 8 x 2.5” 15K SAS HDD, 2 x 1100W PSU, FC8 Dual
Port HBA and H730 miniPERC cards.
4. Idle means the state in which the product is doing nothing but running OS; values for Operating are the maximum acoustical output for
active HDDs or active CPUs.
5. LwA – UL is the upper limit sound power levels (LwA) calculated per section 4.4.1 of ISO9296 (1988) and measured in accordance to
ISO7779 (2010).
6. LpA is the average bystander position A-weighted sound pressure level calculated per section 4.3 of ISO9296 (1988) and measured in
accordance with ISO7779 (2010). The system is placed in a 24U rack enclosure, 25 cm above reflective floor.
7. Prominent tone: Criteria of D.6 and D.11 of ECMA-74 12th ed. (2012) are followed to determine if discrete tones are prominent. The
system is placed in center of ISO7779 table and acoustic transducer is at front standing operator position, ref ISO7779 (2010 Section
8.6.1, Position P1).
Acoustical dependencies
System thermal profile Selected in BIOS: The system default setting is “Power Optimized (DAPC)”,
which is in general a lower fan speed and noise level. If “Performance optimized” is selected, the
fan speed/noise level will increase.
CPU power:
— Configurations with “low-power” CPUs (which have lower temperature limits than standard
CPUs), such as an Intel Xeon E5-2650L v3 or E52630L v3 at 65W CPU, under moderate or
heavy utilization, will be about twice as loud as typical configurations.
— Configurations increase in loudness as CPU power increases from that in typical
configurations.
Types of storage devices:
— HDD:
> Lower speed hard disk drives (such as 7.2K RPM SATA) are generally quieter than 10K/15K
RPM SAS drives.
> Loudness increases with the following progression of drives: SATA, SAS 10K, SAS 15K.
— SSD:
> SSDs are not themselves audible.
> However, a configuration with PCIe SSD requires more airflow for cooling and will be
louder than a typical configuration. Under highly-stressed condition, the sound power
levels may go up to 8.0 bels.
Types of PCIe cards: Configurations with a 10/40GbE NIC or PERC H730 card installed increases
the fan speed causing the system to run louder than a typical configuration.
