The GST D2D Backup Appliance is part
of GST’s StorageDR™ family. The Backup Appliance
handles all save & restore functions for a wide variety
of enterprises needing rapid central backup of critical data.
All components are modular and easily connected. Open architecture
is powered by IBM’s Linux-based xSeries and OpenPower™
models that provide a robust scalable base. IBM TotalStorage™
disk technology provides the industries best hard drives for
greater reliability. A rich variety of configurations permits
starting with one Disk Drawer of 6 drives and growing to 16
Disk Drawers of 14 drives each. High performance 10K and 15K
RPM hard drives are available in 73GB, 146GB, and 300GB capacities.
Total capacity ranges up to 69TB native (138TB compressed).
Disk-to-Disk (D2D) technology permits
backing up servers at disk-to-disk speeds. Later, backup data
on the disks in the GST D2D Backup Appliance can be offloaded
to tape media when production demands are less. Data in the
Backup Appliance can be accessed at high speeds for rapid
recall of backup files.
The GST StorageDR™ Family is
engineered to provide a broad range of storage capabilities,
including the management of the storage infrastructure, Hierarchical
Storage Management (HSM), archiving, and tape backup and recovery.
StorageDR products including the D2D Appliance are complemented
with IBM TotalStorage hardware and optional services including
consulting/assessment, training and financing.
Major features of all GST storage solutions
in the StorageDR™ family include:
• Easily configurable with
a wide variety of component choices
• Modular components
• Scalable as needs arise
• All IBM hardware
GST Backup Appliances utilize rack-mountable
components and can be housed in GST’s 11U, 25U, or 42U
rack for easy installation and maintenance. A D2D starter
configuration might contain a single processor and 2GB of
memory, 2MB of Cache, 73 GB of 10K disks, single SAN switch.
Later, add additional processors, additional 1, 2 or 4GB of
memory, a RAID card and additional Fibre switch options. To
accommodate scalable expansion, a variety of rack enclosures,
storage towers and PCI-X Expansion Slot kits are available.
MODEL OVERVIEW
Backup Appliances are available with
Fibre or SCSI connectivity. Models support up to 4 processors
in three different speeds. Each base Server Option has 2MB

• 2750-8040 > 300GB/10K HDD – Max +230
BENEFITS OF DISK-TO-DISK TECHNOLOGY
Reliability –
While tape continues to make strides in improving its reliability,
disk is inherently more reliable, both in the device itself
and in the media. Disk drives have a Mean Time Before Failure
(MTBF) rating of 600,000 to 1,000,0000 hours, while the
latest advances in tape are in the 400,000 to 500,000 hour
range.
Speed – D2D
speeds are far closer to the speed of the server than D2T
speeds, resulting in a backup operation from disk-to-disk
that takes much less time and can be accommodated in a much
smaller backup window.
Fast Access –
The backup data on the target disk array is much faster
to access than data backed up onto tape. GST’s LPAReplication
software can access the data backed up to disk quickly,
leaving the tape media for disaster recovery functions (where
both disk resources are lost to a disaster). The Hierarchical
Storage Management (HSM) aspect of LPARreplication™
enables the rapid access of files backed up on the target
disk array.
Security –
Data that was initially backed up to the target disk array
is migrated using LPAReplication™ to a tape device
located on a separate LPAR or server. This is done in the
background of the primary application jobs on the main server
being backed up. This isolates critical data from the primary
server partition and protects it from viruses, as well as
allowing it to be removed from the premises later to protect
it from physical danger.
Ease of Use –
With LPAReplication™, Disk-to-Disk technology is easy
to implement and use. Few changes are needed in the backup
software being used for the D2D portion. GST’s LPAReplication™
is policy-driven with menus and fill-in screens that make
configuration of the solution easy and self-documenting.
KEY BENEFITS
LPAReplication™
- GST’s exclusive LPAReplication™ software runs
on the two most popular versions of Linux: Novell SuSE Linux
and Red Hat Linux. Most computing environments are supported
by LPAReplication™. Therefore, the D2D portion is
conducted on the user’s server under their own operating
system environment. The D2T portion on the target disk array
must be conducted in Novell SuSE or Red Hat Linux using
LPAReplication™. Therefore, the D2D part must be located
in a separate partition set up for Linux, or located on
a separate Linux server.
Hierarchical Storage
– Backup data stored on the target disk array can
be used to provide fast and ready access to these files,
should the need arise. Instead of locating the data on backup
tapes that have most likely left the premises, data can
be retrieved from the target disk array for use by the system.
LPAReplication™ contains Hierarchical Storage Management
(HSM) capabilities to do this. Most-active files can be
permanently retained on the target disk array, or purged
periodically.
GST Storage Manager
– GST’s LPAReplication™ disk management
tools optimize use of disk in the Backup Appliance.
Transparency –
The source server sees the Backup Appliance as an IBM 3583
tape library.
Open Architecture –
Linux operating system running on the IBM xSeries and OpenPower
servers permits connectivity to a wide variety of servers
and enables low cost of ownership.
Space Saver –
The small dimensions and modular configurations facilitate
the optimum use of datacenter space.
Serviceability –
Modular building-block design permits individual drives,
servers and other modules to be easily serviced or replaced.
KEY FEATURES
Scalable Processors
– Can start with a single processor of 2.2, 2.7 or
3.0 GHz and add processors, up to four.
Scalable Memory
– Memory can be added in 1, 2, 4GB increments up to
a total of seven additional memory cards, providing a range
of memory from 2GB on the base processor to 30GB with the
scalable memory options.
Scalable Disk –
Both 10K RPM and 15K RPM disks are available in units of
73GB, 146GB and 300GB. Disk can be added as needed to create
a disk capacity that can accommodate expanding requirements,
up to 230 drives. Maximum capacity for 230 x 300GB drives
is 69TB native (138TB with compression).
Scalable PCI Expansion
– Additional PCI-X Slot Expansion options are available
for 6 slots and 12 slots.
Rack-mountable Enclosures
– Individual modular enclosures enable each Disk Drawer
and other modules to be handled separately; field upgrades
of additional Disk Drawers are simple.
11U, 25U, 42U Equipment
Rack – Standard equipment racks hold the
many different configurations of the Backup Appliance plus
other servers that are being backed up.
Scalable Connectivity
– Wide range of IO cards provides considerable choice
in configuring Fibre Channel (FC), SCSI and RAID connectivity.
Service and Support
– A variety of support programs provide installation
and onsite service; includes IBM support and GST’s
Accelerated Ship Program (GASP) to speed replacement units
to the scene rapidly.
Warranty –
Purchase price includes GST’s 3-year warranty.
