device ID or handle. There are three 'Link Speed' columns: 'Supported'
denotes the link speed capability of the phy/device, 'Enable' denotes the
current link speed setting, and 'Control' denotes the link control setting.
Example of 9690SA-8E connected to drives in an enclosure:
// localhost> /c3 show phy
Device --- Link Speed (Gbps) ---

phy1 500050e000030232 ENCL N/A 1.5-3.0 3.0 Auto
phy2 500050e000030232 ENCL N/A 1.5-3.0 3.0 Auto
phy3 500050e000030232 ENCL N/A 1.5-3.0 3.0 Auto
phy4 500050e000030236 ENCL N/A 1.5-3.0 3.0 Auto
phy5 500050e000030236 ENCL N/A 1.5-3.0 3.0 Auto
phy6 500050e000030236 ENCL N/A 1.5-3.0 3.0 Auto
phy7 500050e000030236 ENCL N/A 1.5-3.0 3.0 Auto
In the above example, for phy1, the link speeds supported are 1.5 and 3.0
Gbps. The current link speed for phy1 is 3.0 Gbps, and the link control setting
is 'Auto'. The link control setting could be either 1.5, 3.0, or Auto. 'Auto'
denotes Automatic Negotiation, where the best negotiated speed possible for
that link will be used.
(Note that if SAS 2.0 is used with a 9750 controller, the link speeds can be up
to 6.0 Gbps.)
Example of 9690SA-8I with direct attached drives:
