Which two statements describe the COMSTAR framework available in Oracle Solaris 11?
A.
It converts an Oracle Solaris 11 host into a SCSI target device that can be accessed over a
storage network by Linux, Mac OS, or Windows client systems.
B.
iSCSI targets cannot be configured as dump devices.
C.
It provides support for iSCSI devices that use SLP.
D.
It is used to connect to Fibre Channel or iSCSI Storage Area Network (SAN) environments.
E.
It provides an upgrade and update path to convert your iSCSI LUNs from Solaris 10 systems.
Explanation:
A: You can configure Common Multiprotocol SCSI TARget, or COMSTAR, a
software framework that enables you to convert any Oracle Solaris 11 host into a SCSI target
device that can be accessed over a storage network by initiator hosts.
This means you can make storage devices on a system available to Linux, Mac OS, or Windows
client systems as if they were local storage devices. Supported storage protocols are iSCSI, FC,
iSER, and SRP.
B: iSCSI targets cannot be configured as dump devices.
Reference: Oracle Solaris Administration: Devices and File Systems, COMSTAR and iSCSI
Technology (Overview)
Limitations:
– Does not support iSCSI devices that use SLP.
– iSCSI targets cannot be configured as dump devices.
– Transferring large amounts of data over your existing
network can affect performance.
A and B
Mmmh… not sure if I agree but correct me if I’m wrong… I say it’s B and D.
I don’t know about A, but C is definitely wrong. Support for iSCSI devices that use SLP is not currently available.
Here is my reason for B and D: Reference: COMSTAR and iSCSI Technology (Overview)
“Here are the benefits of usingiSCSI targets and initiators in Oracle Solaris:
The protocol can be used to connect to Fibre Channel or iSCSI Storage Area Network (SAN) environments with the appropriate hardware.”
@Phumlani : A is definitely true. Refer http://docs.oracle.com/cd/E19253-01/819-5461/gcfhe/index.html
Correct Link : http://docs.oracle.com/cd/E23824_01/html/821-1459/fnnop.html
A is true as Saeed said

“COMSTAR, a software framework that enables you to convert any Oracle Solaris 11 host into a SCSI target device that can be accessed over a storage network by initiator hosts.

I’m also doubt with B,D

“Here are the benefits of usingiSCSI targets and initiators in Oracle Solaris:
– The iSCSI protocol runs across existing Ethernet networks.
-You can use any supported network interface card (NIC), Ethernet hub, or Ethernet switch.
-One IP port can handle multiple iSCSI target devices.
-You can use existing infrastructure and management tools for IP networks.
– You might have existing Fibre-Channel devices that can be connected to clients without the cost of Fibre-Channel HBAs. In addition, systems with dedicated arrays can now export replicated storage with Oracle Solaris ZFS or UFS file systems.
– The protocol can be used to connect to Fibre Channel or iSCSI Storage Area Network (SAN) environments with the appropriate hardware.
Here are the current limitations or restrictions of using the iSCSI initiator software in Oracle Solaris:
– Support for iSCSI devices that use SLP is not currently available.
– iSCSI targets cannot be configured as dump devices.
– Transferring large amounts of data over your existing network can have an impact on performance.”

A,B
The Problem is, A B AND D are correct…
A: “This chapter describes how to configure Common Multiprotocol SCSI TARget, or COMSTAR, a software framework that enables you to convert any Oracle Solaris 11 host into a SCSI target device that can be accessed over a storage network by initiator hosts.

NOT C: “Support for iSCSI devices that use SLP is not currently available.”

D: “The protocol can be used to connect to Fibre Channel or iSCSI Storage Area Network (SAN) environments with the appropriate hardware”

hrm.. have a look to the question
i think, we’re thinking to complicated.
=> what “describe” the COMSTAR framework?
So what can i do with that… – not what are the special options.
If you talk to an other person, what would you say?
COMSTART Converts a Sol11-host to a SCSI-Target (linux,windows…)
You can Connect FC odr iSCSI SAN environments.
A, D …?
Surely AB
=>A
