ST9900 devices, will be able to provide a comprehensive set of
information related to the possible nature of the failure. For
non-ST9900 devices, the ST9985V will be able to provide basic
information but will not be able to report specific FRU (Field
Replacement Unit) information. The externally attached device must
have its own call-home facility enabled through which the maintenance
provider will be able to collect the necessary service information.
Sun does not assume responsibility for maintaining third party devices
externally attached to a ST9985V.
The ST9985V appears as a Windows Host to the externally attached
device, which is similar to the way many other devices are normally
connected to both ST9900 and third party systems. Thus a ST9985V
attachment should not have any impact on third party maintenance
agreements.
Q. How is Dynamic Provisioning Software Licensed and Priced?
A. Dynamic Provisioning Software is based on the usable capacity Dynamic
Provisioning Pool size. You do not need to license Data Provisioning
(HDP) for the whole system amount, only the amount needed (Used
Capacity).
Q. Is Dynamic Provisioning software supported on existing ST9990/85 products?
A. No, Dynamic Provisioning Software (and thin provisioning
functionality) is only supported on the new ST9985V and ST9990V
platforms.
Q. Does Dynamic Provisioning work with z/OS
A. No, Dynamic Provisioning is for Open Systems only supporting OPEN-V
Q. Where can I get even more information on the ST9985V?

Q. Has there been any improvement in the single port performance (FED and
BED Performance)?
A. Yes. While we have not released audited SPC1 figures at this time,
unofficial tests suggest that there may be significant performance
improvements. Please stay tuned on these performance numbers.
The key point is that the Front End Directors (FED) and Back End
Directors (BED) have been re-designed to allow unused microprocessors
(MP) to take workload from other microprocessors on the FED or BED.
This is a significant contributor to improved overall throughput.
From an overall performance perspective, the ST 9985V is now end to
end 4 Gbit. Both the FED, BED, and the HDDs all operate at 4 Gbit.
Q. What is really meant when the ST 9985 V is claimed to have a "Switched
FC Backend"? What about those claims about improved diagnosability
and reliability?
