Those are some interesting comments. Here are some of
my own.
1. It is hard to work out exactly what they are
offering. There are lots of words in there but it is
all a bit nebulous.
Hopefully, the new arch doc well help in this area.
2. HSM has been around for a long time but has had
comparatively little uptake as people don't really
like it. I think they worry about the wrong tape
being available and having to worry about having a
tape library just for HSM. How about offering the
option of a secondary disk store that is usually spun
down so you get the benefits of not having to back it
up and power draw, but subject to the disks spinning
up will be instantly available.
Going to secondary disk works but probably still
needs to be backup in some fashion.
3. How does the concept of spooling directly to
tape work with versioning. It may be that someone
save and re-edits a file many times, in which case you
end up with a tape full of different versions. There
needs to be a tape consolidation method.
I thought we had drop the idea of versioning.
4. In the corporate environment directory services are
becoming increasingly relevant, with both NDS and now
Active Directory. Most storage centric manufacturers
neglect the requirement for any devices to fit in with
the directory structure.
This is good knowledge and something that probably
needs to be researched. Does EA or Samba support
Active Directory. What is NDS?
5. WORM in the legal environment utilises a disk
technology that cannot be rewritten no matter what you
do to it. That is why it stands up in court. This is
clearly changeable with a switch so the legal bit is
of no use. However it could be useful in non legal
environments.
I assuming there is some kind of miscommunication
here. I'm assuming the bit would send the doc to a
permanent medium. So changing the bit would only
affect further updates.
6. They mention multiple 200Mb/s streams. Clearly as
with Tricord this bandwidth capability is crucial.
This is cleary dependent on the hardware.
7. One thing that doesn't seem to exist in the
market is a packaged backup solution. NAS appliances
assume that all the data is going to reside on the
appliance. This cannot always be the case, or may not
always be desirable. For example, there are always
arguments about the merits of putting databases or
installable file systems, such as Exchange, on NAS.
With products like Bakbones Netvault there are newish
backup software products that cover a wide range of
platforms and offer a wide range of library support
with optional disk staging. The problem is that you
cannot disk stage to a network drive, so you end up
having to put in a dedicatedish backup server. How
about a packaged device that has all the connectivity
they are talking about, including the library support,
but with a decent backup application running on the
box so you have local disk staging, directly attached
tape library and if they can do snap shotting of the
arget data to backup it could be really interesting.
What does he mean by disk stage to a network drive?
