Ideal DAS
Replacement Solution From Qsan P100C iSCSI RAID Controller

With iSCSI nature and Qsan’s features, when IT
administrators design storage solutions for SMB
environments, Qsan P100C is an ideal replacement for DAS and
has more flexibility for future planning. Comparing to SCSI
DAS storage, P100C doesn’t need a HW HBA. And most OS
support free iSCSI initiators, such as Windows and Linux. If
this storage solution is designed for multiple servers / PCs
access in the same time, iSCSI shows its advantages here,
and Qsan P100C iSCSI RAID controller can support up 32 host
connections in the same time on the existing network
infrastructure. If higher performance, multiple connections
and better management are required, an 8 port GbE switch
costs less than a dual port SCSI HBA, and if more
connections are required, a 24 port GbE Switch only costs a
little more than a dual port SCSI HBA. By iSCSI
installation, IT administrator can reserve flexibility for
the future, including adding more server/PC connections,
scalable capacity expanding, virtualization, no distance
limitation, easy migration, interoperability, and etc. For
more price and function comparisons of DAS to iSCSI, please

Beside the iSCSI advantages, Qsan P100C iSCSI GbE (X2)-SATA
II RAID controller is also embedded with rich features, such
as flexible drive number support from 4 ~ 8 bay tower, 1U4,
2U8, 3U12, and 3U16 subsystems, RAID 6, jumbo frame, access
control, disk auto spindown, iSNS, CHAP authentication,
online migration, web UI management, and etc. P100C is built
around with Qsan innovative RAID stack, featuring
industry-leading performance on Intel IOP platform. With 2
GbE iSCSI ports connected to the host/GbE switch, either
working independently, MC/S, or MPIO together, the
throughput can achieve up to 190MB/sec by non-cache hit
configuration. And with the green feature of disk auto
spindown supported by Qsan, the whole subsystem of P100C
even with fully loaded 16 hard drives can achieve high power
efficiency and save the overall drive power cost.
It is painless and quick to integrate into your current
chassis designs. Qsan’s support team can shorten your
project time by providing fast design capability and overall
reliability test. The overall cost is very effective. With
low price tag, rich advanced features support, and numerous
OS/HBA/iSCSI initiators/HDD support, P100C iSCSI(X2)-to-SATA
II controller is ideal for the SMB market applications, such
as surveillance, shared backup pool, mail storage, SQL
server, files backup, web server, CRM and etc. Qsan also
provides customization services for hardware and firmware
feature adjustment, such as customization web UI design, BBM
(Battery Backup Module), QSnap snapshot feature support,
enclosure monitoring of power supply, fan, and temperature,
and other customized features. For more details, please
