At this year's HP Americas StorageWorks Conference
(ASC), the computer giant has made a series of product
announcements.HP announced four new products: the EVA x 100 family (consisting
of the EVA 4100, 6100 and 8100 models); a new DAT tape drive, an
LTO-4 tape drive and a tape
backup blade.
One feature of the new EVA that will ship with the first
generally available product this week is fault isolation
capabilities down to the disc level, rather than the disc shelf.
This means that when a single drive fails, the EVA will not have to
take down an entire shelf, improving performance during rebuilds,
the company claimed.
However, two of the key features being touted with the new EVA
family won't be available until the Windows Server 2008 (aka
Longhorn) release later this year. The first is support for Server
2008's Virtual Disc Service (VDS), which allows for the growth and
shrinking of volumes according to application demand. The second is
a similar feature within the EVA array, which is being called
Dynamic Capacity Management (DCM) -- essentially, HP's side of the
VDS equation.
According to Kyle Fitze, director of marketing, storage area
network (SAN) division, HP StorageWorks, the ability to dynamically
grow volumes without rebooting the array will be available before
the ability to shrink them. As for when that will be -- "sometime
before" Longhorn's release; Fitze declined to be more specific.
Other features HP was touting with the EVA array turned out on
further inspection to either have catches in the fine print or not
really to be new. For example, the addition of 4 Gbps Fibre Channel
connections; these have been added, according to Fitze, between
server and storage, as well as within the controller, but not in
the connections between controller and disc; meaning that 2 Gbps is
still as fast as the system can extract data from discs. The system
also has about a 24% performance improvement due to new processors
in the controller.
"We plan to check [the 4 Gbps] box in the next generation
product," Fitze said, arguing that most customers won't fill up the
pipe.
Another feature HP was pushing in its press conference was the
ability to create writeable snapshots, saving only changed data
rather than creating full clones, a capability analysts were quick
to point out HP has had available for years.
"They've done a poor job of getting the message out about it and
educating the market, or maybe they've been waiting for extensive
field tests to validate its use," said Tony Asaro, analyst with the
Enterprise Strategy Group (ESG).
"I don't know that I could confirm that it's been around for
years, but has it been in existence before? Yes," said Duncan
Campbell, vice president of worldwide marketing for HP
StorageWorks.
More fine print: LTO-4 drive and tape blade
While several of HP's competitors are already shipping LTO-4
drives, HP's newly announced drive won't ship until August.
According to Ash Ashutosh, vice president and chief technologist,
StorageWorks division, this is because the key management
application is still being developed. "We need to make it
enterprise wide, not device specific," he said. "Shipping key
management with only the tape drive would be useless."
The products that are shipping in full are a new DAT 160 drive,
as well as the HP Ultrium 448c Tape Blade, a new half-height tape
storage blade that provides data protection for HP BladeSystem
c-Class servers and the SB40c storage blade. According to Ashutosh,
both the SB40c and the 448c are direct attached storage (DAS)
devices for the BladeSystem chassis. A networked storage blade
device is expected to be released in the fall time frame.
The tape blade is two generations behind the most current Linear
Tape-Open (LTO) format, with support for LTO-2 drives only.
According to Bob Wilson, vice president of nearline storage for HP,
this is because HP "wanted to align the capacity point with what's
typical in the blade chassis, which is usually the boot drive in
the server and also achieve the most competitive price point." (The
suggested list price for the blade is $1,999.)
What about software?
Meanwhile, there was no sign of a
rumored blade that would add continuous data
protection software from FilesX Inc. Or some of the updates that
were discussed last year, including block-level data
deduplication for the RISS archive platform. The HP story around
that particular feature, slated for release last September
according to briefings at last year's StorageWorks event, is
that the RISS storage cells have the dedupe capability within
them, but the Research in Motion (RIM) software management
modules haven't been updated yet, precisely the same story as
last year.
RIM for Files, which was supposed to be the first module for
dedupe with RISS, was delayed "for inventory reasons," according to
Patrick Eitenbichler, director of marketing for HP's StorageWorks
division. However, he said, the release is coming "just around the
corner".
Industry reaction
"I think there's an internal argument going on," said Howard
Jares, a systems administrator for a large university in Texas who
asked that it not be named. "I think they're trying to position
themselves in every area of IT, but it's hard to be everything to
everyone."
"I haven't seen a lot of functionality changes, though I have
seen a lot of improvements in stability and performance," said
Storage Essentials user Jeff Machols, systems integration manager
for CitiStreet. "It's been slow."
According to ESG's Asaro, "HP does a great job in setting up a
strong story. They talked to us about grid way back when, now it's
all about 'blade everything,' but we haven't seen excellence when
it comes to execution. They have all the ingredients, but they
don't have a cake."
HP officials pointed to the acquisition of PolyServe Inc.'s file
services software, the new low-end virtual tape library (VTL)
released in February and the All-in-One box as signs the HP storage
software business is still going strong. "Customers want to hear
what's coming, but the way we've described our long-term strategy
over the years has changed because customer needs have changed,"
Fitze said.
So how can customers be sure the new software features for the
EVA, for example, will really appear? "We're already far too
committed to delivering DCM, we're heavily involved with Microsoft,
and there's too much at stake not to deliver on this one," Fitze
said.
