4.4 SATA Differences and Limitations

This section describes the differences between the SAS and SATA versions of the 2U24 Flash Storage

Platform.

The2U24 Flash Storage Platform has a varietyofSKUs availablethatcanbe referencedinTable 3: Available

SKUs on page 16. Some of the SKUs available leverage SAS based SSDs, and others referenceSATA based

SSDs. The following is a list of general differences of SATA to the SAS versions.

• SATA based SKUs only come with a single ESM. SAS SKUs come with redundant ESMs.

• The SAS based drives are capable of 12Gbps transfer rates, while SATA is limited to 6Gbps

• The SATA devices are limited to a single initiator when references by host devices.

4 Product Overview

User Guide 4.4 SATA Differences and Limitations

4.4.1 SATA Single Initiator Limitation

The ATA protocol is not capable of handling multi-initiator access which means the 2U24 Flash Storage

Platform only supports a single SATA affiliation to one initiator. If multiple initiators are connected to an

enclosure with SATA devices installed then the initiator that first discovers the SATA device will be given the

affiliation to that SATA device. This creates a scenario where it is hard to control which initiator has access

to specific SATA devices within the enclosure. If multiple initiators must be used with a SATA enclosure then

zone the enclosure so each host port on the ESM only has access to a specific number of SATA devices

within the enclosure. This will prevent any variability in the device discovery process.

4.9 System Cooling

The 2U24 Flash Storage Platform has an advanced thermal algorithm that monitors all of the temperature

sensors in the system. The enclosure makes adjustments to the fan speeds based upon the thermal sensors.

The fan algorithm takes into account the component and the warning and critical threshold limits set by SES.

If any temperature sensor gets to the warning limit, the fans speeds will increase to cool the component. If

theenclosure encounters low temperatures,thesystem will reduce fan speed in anattempt to conservepower

and not over-cool the enclosure.

This algorithmisagnostic to effects of altitude and humidity. The algorithm simply worksbasedon temperatures

within the system with emphasis on reducing power consumption.

4.10 ESD

The enclosure is designed to dissipate all electrostatic discharges to the chassis base. Ensure that there is

sufficient electrical and mechanical connection from the chassis base to the rack rails, and that the rack itself

is tied to earth ground. It is recommended that suitable ESD precautions be observed during installation and

service operations

The unit must be grounded in accordance with all local/regional and national electrical codes.
