The Dell Tiered Storage Solution is delivered as an all-inclusive storage data management solution and
is available with deployment services and full hardware and software support from Dell and
CommVault. The solution design uses the following principles:
 Standards-based HPC components
 Ease of deployment
 Ease of use
Dell tiered storage solution technical overview
This section provides a quick summary of the technical details of the Dell Tiered Storage Solution (TSS)
offering.
The Dell TSS offering consists of a Dell PowerVault DL2200 Disk-Based Backup Appliance and a
PowerVault ML6000 Modular Tape Library; you can use more than one. The DL2200 appliance serves as
the HSM data manager and utilizes CommVault Simpana 9 Data & Information Management Software,
but it is not in the data path for the actual HSM or archive process. This is the central point of the HSM
network, where storage resources and policies are created and administered. The PowerVault ML6000
Modular Tape Library serves as the designated long-term storage tier in this solution. This Long-Term
Storage or LTS tier allows for low cost/high capacity storage and for long term retention of data. You
can consult the accompanying documentation
(7) or the Dell deployment service team for proper rack
and stack procedures as well as loading and initializing of the drives and tape cartridges.
Dell TSS supports the Dell NFS Storage Solution (3) (NSS) as the designated primary storage tier in both
standalone (NSS) and high availability (NSS-HA) configurations. The NSS and NSS-HA solutions use the
NFS file system on top of the Red Hat Scalable File System Add-on (based on XFS) with Dell MD
PowerVault as back end storage, to provide an easy to manage, reliable, and cost-effective solution for
unstructured data.
Dell also offers the Dell | Terascala HPC Storage Solution (DT-HSS) that you can be designate as the
scratch storage tier. Though not actively supported in the HSM network, manual movement of data
between the DT-HSS scratch storage space and NSS primary storage space can be achieved through use
of manual move commands or by scripts and even in job scheduling scripts. The data can then be HSM
or archive between the NSS primary tier and ML6000 Tape library long-term storage tier.
