| 456.9 | need counter to Tandem's claims | FIREBL::LEEDS | From VAXinated to Alphaholic | Wed May 28 1997 15:12 | 15 |
| We are no running into Tandem a lot in the NT Cluster arena. I got the
attached from a Sales Rep who almost had a deal closed for a number of
AlphaServers running Digital NT Clusters, now they are leaning towards
Tandem.
Do we have any real technical scoop on what they're offering (especially
around the "dual SCSI path" statement) ?
"They have been shown a Wolfpack add-on product from Tandem that they claim
could be superior to ours. It claims to enable them to have a dual SCSI path
to a single controller from the host. "

Get in contact with the PMs so they can inform you what we
have cooking. (On top of Wolfpack as well)
Since this is an add-on to Wolfpack, I do hope that they
are aware that this is something that they can only have:
Somewhere Fall 1997
As part of Windows NT Enterprise.
Digital NT Clusters can be had today.

| Our StorageWorks people are working on an NT driver to allow dual-path
SCSI connections to our StorageWorks RAID controllers. It's not
connected to cluster software, but does eliminate another "single point
of failure". Don't know what Tandem has for SCSI controllers.

| I'll be evaluating Conley Corp's SafePath product with DC and WP in the
next few weeks. SafePath purports to offer dual path connections to
arrays in a clustered environment.

| 456.13 | in Wolfpack beta2? | HERON::ras5.vbe.dec.com::lalli | Somewhere in Europe | Mon Jun 02 1997 19:38 | 8 |
| In some Wolfpack presentation I saw a note about the dual-SCSI
attachment being supported in Beta 2. I haven't seen it in the
documentation though.
Anybody else?

| 456.14 | FTdisk vs Dual SCSI attachment | AEOENG::16.40.240.154::annecy::lehy | | Tue Jun 03 1997 04:03 | 29 |
| According to the Wolfpack Beta 2 release notes, FTDisk is/will be
supported. ( 1.2 in the release notes)
What is Dual SCSI attachment ? One storage connected to two SCSI
busses or one host connected twice to the same SCSI bus ?
Host
SCSI #0 -----------------------------------------------...
|
Raid Controller
|
SCSI #1 -----------------------------------------------....
or
Host
SCSI #0 ---------------------------------------------....
| |
| Raid Controller
SCSI #1 |
What are the advantages of Dual SCSI attachment against FTdisk support ?

>busses or one host connected twice to the same SCSI bus ?
Two SCSI buses (from the same host) connected to a dual-redundant
HSZ configuration effectively eliminating the SCSI bus as a single
point of failure and, depending on the driver implementation,
increasing throughput via dynamic load balancing across buses.
