Question: Where can I find analyst reports on HDS products? 
Analyst reports are an excellent sales tool and can be found on http://www.hds.com/tools/analyst_reports/

Question: What are the differences between the different levels of customer support?  
Week Day Basic Service has a targeted on-site response time of next business day (NBD). It is our base service offering for storage systems with non-critical applications, such as stand-by data centers, where 24 hour support and a rapid response is not required. 
Standard Service provides corrective maintenance for unexpected problems whenever you need it; 24 hours a day, seven days a week with a targeted on-site response time of four hours for critical situations. Standard Service meets the need for both highly available and economical support services by providing concurrent maintenance and engineering changes during normal business hours.
Premium Service provides the same services as Standard but with a two hour targeted on-site response for those customers requiring a high level of on-site response. Note that this service may not be available in certain areas.

Question: Is TrueCopy supported between a USP/NSC55 and an AMS500/1000?
Using TrueCopy to provide remote replication between an AMS and a USP/NSC is not supported but there is other third party hardware and software options or you can externally attach an AMS500/1000 to a USP/NSC and then use TrueCopy to replicate the AMS data remotely.

Question: What is the difference between the NSC55 and the diskless NSC55?
The NSC55 ?Disk-less? version is not a new product but rather a new ?configuration option? for the current model NSC55. There is no new product name or product number for the ?Disk-less? version. With the exception of certain software limitations, it is physically identical to the current NSC55 product, except that there are no disk drives or disk chassis required with the ?Disk-less? version. (The standard/original NSC55 requires that one disk chassis with a minimum of five (5) disks be configured with each system).

The ?Disk-less? version of the NSC55 contains the same microcode as the TagmaStore Universal Storage Platform and the standard NSC55. Therefore all supported software and interoperability that are available with the Universal Storage Platform and the standard NSC55 models are the same, except as noted here.

The NSC55 ?Disk-less? version has the following restriction:

1. Hitachi Universal Replicator software is not supported
2. The NAS Blade is not supported
3. No mainframe support is provided, i.e., FICON and ESCON connectivity are not supported
4. Hitachi Data Retention Utility is not supported as there are no internal disks
5. The Disk-Less configuration of the NSC55 requires Microcode Level V07 as a prerequisite.

Note: The NSC55 ?Disk-less? version can be upgraded to contain from 5 to 240 disks, at which time the restrictions listed above are lifted, and all of the NSC55 and Universal Storage Platform functionality is supported.

Question: Are HDS Storage products compliant with The Waste Electrical and Electronic Equipment Directive (WEEE Directive) and the Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive (RoHS Directive)?
More information can be fount in the Tools and Applications area of the HDS intranet at http://hdsnet.hds.com/cmsProdPubIntra/grou....

Question: Is the USP/NSC55 Audit Logging feature a separately licensed and chargeable feature?
No, it is included as part of the Resource Manager package at no additional charge.

Question: Up to 64K LDEVs are now supported for the mainframe environment. When will we support 64K LDEVs for Open Systems?
There is no current plan to support 64K LDEVS on the USP or NSC55.

Question: Is there any plan to support Network Appliance storage as externally attached storage with the USP/NSC55?

Question: I have a customer that will have 4 physical hosts running VMware ESX connected to an AMS box. There will be six virtual machines running on each of these four hosts. Will I need 24 HDLM licenses if they all will be accessing the disk directly over FC?

You will need NO HDLM licenses.  Failover is built in to the VMWare OS.

Question:  How do virtual ports work with VMware if I have six virtual hosts utilizing the same two HBAs?  Are the WWNs of the shared HBA ports changed for each virtual host or are there some other scheme used to allow RH 3.0 and Win2k3 virtual hosts share the same HBAs without the Windows host seeing the Red Hat server's LUNs?
That is taken care of in the VMWare OS.  The physical WWN's of the HBA's will be presented to the storage array.  The storage array will present the LUNs to the VMWare OS.  ESX takes care of giving each virtual machine their resources.
