Thinking about LTO-8 Tape?
We caught up with IBM Storage executives to get the thoughts on the release
of LTO-8 and tape storage in general.
LTO-8 Video Transcript.
With data growth rates now measuring in
the tens of zettabytes annually it comes
as no surprise that IBM's announcements
around tape storage have the industry
buzzing. We traveled to the IBM executive
briefing Center in Tucson Arizona to get
information about IBM's new LTO 8
technology firsthand. A few years ago we celebrated 60 years of tape and 59
years of tape is dead and so yeah tape is
very uniquely positioned for really kind
of I'll say two key aspects one is the
extremely high capacity it stays on that
areal density curve and stays ahead of
disk and and while there may be
occasional variations of coming closer
together and opening up differences tape
has maintained that for many many years
the cost-effectiveness you know goes
across industries everybody needs to
save money everybody needs to deal with
storing in a cost-effective manner and
and then kind of a side to highlight of
cost-effectiveness. There's a lot of
parameters and TCO including density and
so tape densities you know exceed all
other storage densities and as we
maintain those areal density
improvements I started out 31 years ago
with IBM as a developer for DF HSM on
the mainframe and its sole function was
to move hot data once it cools off from
disk to move it on to tea and 80 90
percent of mainframe customers their
data is cold on tape being kept for
long-term purposes for a variety of
legitimate reasons leaving the disc and
flash for the hot data that needs all of
that performance at its optimum now on
other distributed system such as UNIX
and Windows and Linux we're finding the
same dynamic applies just 20 years later
people are finding that they're keeping
data longer for analytics they're
keeping data longer for government
compliance they're keeping it for active
archives so that they can reference back
to the information and this stuff is
cool
it's not accessed on a daily basis so
yes you still have 80 to 90 percent of
your data is called with the hot edge
the data that is the most recent the
most active data still on flash and disk
if you've been around for a long time
it's like remember the chrome tape which
was the good stuff that you flick the
switch in your tape deck to have the
good good performance all technologies
have evolutions like this chromed mp2
barium ferrite what comes next strontium
ferrite I've heard other things in the
press people have talked about I think
the sputtered is just another example of
the technology that's potentially yet to
be put into tape I like to point at
those as we have roadmap insurance we're
not sitting there bumping our heads
against some technology law of physics
like hard disks cos we have a lot of
options going forward and whether it's
food you and strontium or soneul and
sputtered or something else that we
haven't yet heard about there's
something that we can use to keep
pushing the value prop the tape forward
eric Hertzog chief marketing officer and
vice president with IBM storage division
his fond of comparing the storage
infrastructure model of the company to a
Pittsburgh stake hot edge cold center to
get a bit more detail about what it
hurts augment if we turn to IBM's
thought leaders at the executive
briefing Center in Tucson Arizona what's
interesting about Herzog's example is I
always think to myself ok what are the
sides and the sides better complement
what we intend to deliver associate with
Software Defined an example of that is
what we do is special mark I've LTFS
that enables this idea of consume
ability with regards to file sets and
the data that you want to ensure
simplicity on it's basically like a USB
for tape the primary workload today for
tape is archived for backup 70% of
backups are still on tape 30% are either
on cloud or disk based approaches
virtual tape libraries or disk
repositories for storing up backups or
even you know USB thumb drives or or USB
external drives as a way
to do backups so it's still a huge role
for backups to use tape but the real
advantage is long-term retention if you
look at the costs over say seven to ten
years you would have to swap out your
disk
two or three times during the same time
you have one tape generation with one
tape library and tape cartridge
technology during that same period so
you would have more stability if you
will on the tape environment than having
to do it on a disk that gets changed a
lot whether you're talking about IBM
zenterprise tape format Jaguar or the
linear tape open LTO format tape is
coming into greater use even by clouds
which were once touted as a tape killer
platform tape is a very important to
cloud providers I think they're
providing some of our best not only our
best testimonials of the benefits of
tape but it's kind of exciting times for
us in terms of driving new requirements
driving new needs for innovation for us
as developers we that's the kind of
thing we thrive on that's coming from
the cloud providers and then what we see
is the kind of a tip of the spear others
other those of our customers saying yeah
I want that even if you're you're
putting that disc on to cloud storage
with fast access characteristics that's
also being backed up somewhere in the
cloud and and there are going to be some
high percentage of them that are that
are utilizing tape for that reason we
partner with cloud service providers
that they come in with their their
mountain bikes and camel packs in order
to substantiate their the provide for
different thinking usually deeper
thinking with regards to what's required
for LTO or potentially Jack our partners
in the cloud services area are both
enterprise as well as entry to mid-range
based on their particular use cases
associate with a the environment that
they intend to run some of the
technology end so so cloud service
provider
we feel like there's a vertical now that
is clear and we IBM wannabe part of that
infrastructure some pundits and trade
press writers have recently called into
question the efficacy of tape when used
together with so-called active archives
they wonder whether or not data can be
retrieved from a tape fast enough to
make it useful for applications such as
big data ibn gave us their view some
analytics is crunching data that is
within the same 24 hour period however
there's other data that you are looking
for long term trends long term analysis
and the process of analytics is terribly
slow to begin with it's mathematical
models that take hours or days to do and
the time to fetch the data from tape is
the least of the problems it really
isn't
affecting the maskull models it fetches
data it processes the data if then
fetches more data and processes the data
and then the time that it's taking to
process the data it has to do all of the
math it has to do a variety of cross
correlations to look for those patterns
and develop these models again the time
to fetch the data from tapirs is not the
major bottleneck we have a project at
the Kennedy Center in Washington DC they
record all of their TV shows awards
ceremonies things of that nature and
they have most of the data on tape with
maybe the first three minutes on flesh
so when you hit the play button you're
playing the first three minutes from
flash and that gives us plenty of time
to fetch the tape and position it which
on average is 75 seconds total from the
time you actually start the robotics to
the time you position that 40
milliseconds to actually go from the
front of the tape to the middle of the
tape is is is too small to even consider
in that space but doesn't matter it's
it's ready to go people are familiar
with buffering on Netflix or whatever
when they're watching and it's basically
fetching from tape you tube you watch
another video for advertising while it's
buffering from tape and then you watch
the actual video you're looking at
and nobody seems to have a problem with
that in fact it can be monetized I like
a set tape that big 20 to 25 times
cheaper than discs really you can
compensate for a lot with that
difference in price in addition to
capacity durability and cost efficiency
another reason for the renewed interest
in tape may very well be data security
at the end of the day IT budgets aren't
going up but data storage requests and
demand is going up so you have to figure
out how to solve that problem and you
can't do it all online and I do think
your point about the recent hackathons
and things like that that are exposing
weaknesses on online data is going to
drive some demand into tape for that
air-gap reason I mean Google's lost
years ago wasn't a wasn't a hack it was
a software bug as I understand it but it
illustrates the same point as they had
to have that air gap to have that
disease or whatever you want to call it
not propagate through everything and
yeah I think some of the large cloud
guys are actually looking at it for that
reason too is how do I create an air gap
that I don't have to worry about getting
infections running across my whole
environment the air gap is very
sensitive right now because of breaches
and ran somewhere where they hack into a
system and are able to encrypt your data
and then hold you ransom with having to
pay to get your data back and having
that air gap means that you have some
data protection preventing that
modification and encryption that could
easily be unnoticed otherwise the
encryption is certainly a critical
factor we had a state government agency
I won't tell you which state in the
United States but their model of
disaster recovery was to give the most
recently new hired employee a box of
cartridges to store in the back trunk of
his car so that it would be stored in
his apartment in that in the garage of
his apartment and then
the next day and they used that
methodology for a while until somebody
had their car stolen
so encryption became very important in
the tape world in these breaches that
were finding only 4% is encrypted 96% of
the world's data is unencrypted and for
a long time that was because it impacted
the performance impacted the database
performance it impacted online
transaction processing but in a tape
environment its real-time the encryption
happens at line speed there is no
trade-off with encryption you get the
encryption immediately and everyone
encrypts their tapes there isn't anyone
who isn't encrypting their tapes and the
cost is managing keys and so we have a
security key lifecycle manager that
basically keeps track of the keys and
doles them out to the tapes when needed
and it's all done over a secure
connection so that unless you have
access to those keys you can't make any
inference of the data on the tape we
were the first from a technology
perspective to deliver tape encrypting
drives in addition we work with partners
based on the software side or even in
mainframe to enable this idea of
pervasive encryption so tape is highly
secure and we intend to improve our
overall security as we learn more
because we have to substantiate a highly
secure environment for some of the most
at risk clients we have in the
marketplace even with the many
improvements in tape technology that
we've seen over the past two decades
there are still those who are concerned
that a skills gap is going to inhibit
the adoption of tape technology going
forward it's important that we ensure
that we scream from the rooftops about
tape and how we enable consume ability
within certain workloads
like for instance virtualization so in
partnership with VMware were more now
thinking about how to is
- what we do with the 4500 or the tape
library line and grow from a stackable
3u and beyond be careful people of our
age group have a tape experience and a
lot of it is ejecting the VCR and
pulling out the 3-inch threads of tape
inside and trying to get the rest of it
out of there right so there is this kind
of consumer tape problem for our
generation of all the hassles with tape
getting pulled apart the newbie
generation actually it's probably going
to be much more accepting of tape once
they start using it because they don't
have that kind of consumer based
experience all they have is the IT based
experience which of course as you know
is night and day different than a
consumer tape experience it's kind of
like considered you know comparing you
know consumer flash to a large mainframe
sort of flash much difference in
performance much difference in
reliability so I'm actually we're
looking at one of the things we're
trying to do in IBM is is kind of
promote tape to be more usable we're our
research in Zurich is working on
something we call open LTFS which is
essentially a think of it as a spectrum
archive non-clustered that we would like
to make open sourced we are putting a
swift stack on top of that HLM Swiss
stack which is basically a latency tier
so that you can have optical made or
tape in an object store part of the idea
is now that becomes something that can
be consumable in universities and other
places very simply you don't have to
have it at a pad and somebody go get a
special software you know backup
application to use tape now you can
download the open-source Swift stack you
can use the open source open LTFS and
you can have a small tape presence in a
small lab without a huge cost in the
complexity so that's part of this idea
of we need to make tape relevant again
from the ground up almost we have
wrapped tape with tape libraries and
automation to the point where it's yet
another black box that you point data
act and with all most of that automation
rarely do you have to physically touch a
tape cartridge physically mount the tape
cartridge or physically put a tape
cartridge in a box and ship it off
somewhere
depending on your business a lot of
median entertainment that used to be
familiar with Betamax and VHS videotape
have easily switched over to LTO tape as
an alternative that stores hundreds of
hours of high-definition video on a
single cartridge that is no change for
them and companies that use tapes to
pass information from supplier to
supplier credit card information things
like that again not anything new to them
this is something they've been doing for
a while I don't see really any unique
skills that couldn't be learned in a few
days or a few weeks regarding tape
there's the proper handling of tape
though don't pour coffee on it don't run
over the cartridge with the truck but
other than that I don't really see a
skills shortage that needs to be
addressed over a longer period of time
it may seem like IBM is ahead of the
curve with its announcement of LTO eight
drives and libraries especially given
the fact that only yesterday we were
being told about their generation 7 tape
technology is there a reason why LTO 8
announcements are coming so far ahead of
the cartridge itself we're now seeing
the I guess you could say the
availability of LTO 8 technology which
is the announcement of the LTO 8 Drive
and when we expect it to be ready for
market we're not announcing everything
like when the media is available because
the t pcs haven't worked through all the
licensing and agreements and all that so
technically we can't really go forward
with everything but we are ready with
the technology and the drive so we're
going to be talking about that we
decided it was important for us to run
to the races deliver an LTO 8 Drive even
though we've just recently of course
delivered LTO 7 to substantiate our commitment as ecosystem partners to the
marketplace as it relates to tape actually LTO 8 is back to our historical pace
an LTO we used to be around two years maybe two and a quarter or something like
that then in the timeframe of the big financial crash in LTO 6 we kind of spaced it out with
more like three years or so now we're
back to the two year pace I mean we're
back to a technology that scales we have
the capability so we generally believe
the market needs more tape and needs
more capacity and if we can do it we'll
do it with today's announcement of a new
LTO eight tape drive IBM is
demonstrating its continued support for
the LTO tape roadmap.
