RAID 6
» What is RAID 6
• Any form of RAID that can continue to execute read and write
requests to all of a RAID array's virtual disks in the presence of
any two concurrent disk failures [SNIA definition]
• RAID 6 can handle the failure of any two drives in the array
• Striping and dual parity (“RAID 5, but MORE”)
» ReadyNAS Pro supports RAID 6
• User configurable
» Why 6-bay Pro with RAID 6 makes sense?
• Capacity = (Size of Drive) * (Number of Drives - 2)
• Storage Efficiency = (Number of Drives - 2) / Number of Drives)
» 4-bay RAID 6 - 50%
» 6-bay RAID 6 - 67%

13
X-RAID2
» What is X-RAID2
• Based on NETGEAR patient-pending X-RAID technology
• The 2nd generation auto expandable RAID technology with
improved performance and incremental capacity utilization
» What’s the advantage of X-RAID2
• Robust and reliable
• Simplified process and optimized performance
• Vertical and horizontal online volume expansion without the
complicated and time-consuming migration and system rebooting
• Optimized utilization of incremental drive capacity supporting
different size of drives
» Limitation of X-RAID2
• Incompatible with X-RAID

Redundant Ethernet
» User configurable option
» Failover for high availability
• Dual gigabit Ethernet ports
on switch/ReadyNAS
• Failsafe against single port
failure for high available
• Supported with all options
» Link Aggregation
• Use dual Ethernet cables and
ports in parallel to increase
the link speed beyond the
limits of any one single cable
or port, and to increase the
redundancy for higher
availability.
• Support IEEE 802.3ad
Client w/ 2 NIC
Note: That the option selected may affect the ReadyNAS network performance.

ReadyNAS Teaming and Failover
» Description
» The ReadyNAS network teaming provides a way to aggregate the two network
interfaces into a single logical teamed, or bonded, interface. The teamed
interface allows for failover support and can provide for enhanced aggregate
performance over a single interface.
» Bonding Options
» Round-Robin
» Transmit packets in sequential order from the first available interface to the
next. This mode provides load balancing and fault tolerance.
» Active Backup
» Only one interface in the bond is active. A different interface becomes active if,
and only if, the active interface fails. The bond’s MAC address is externally
visible on only one port to avoid confusing the switch.
» XOR
» Transmit based on the default simple transmit hash policy. This mode
provides load balancing and fault tolerance.

ReadyNAS Teaming and Failover
» Bonding Options (continued)
»
»
»
»
»
»
»
»
Broadcast
Transmit everything on all slave interfaces. This mode provides fault tolerance.
IEEE 802.3ad
Creates aggregation groups that share the same speed and duplex settings.
Utilizes all interfaces in the active aggregator according to the 802.3ad
specification. You will need a switch that supports IEEE 802.3ad Dynamic link
aggregation.
Transmit Load Balancing
Channel bonding that does not require any special switch support. The
outgoing traffic is distributed according to the current load (computed relative
to the speed) on each interface. Incoming traffic is received by the current
interface. If the receiving interface fails, another interface takes over the MAC
address of the failed receiving interface.
Adaptive Load Balancing
Includes Transmit Load Balancing plus Receive Load Balancing for IPV4
traffic, and does not require any special switch support. The receive load
balancing is achieved by ARP negotiation.

Understand iSCSI
» What is iSCSI
• iSCSI = Internet SCSI, allows SCSI commands to be sent over an
Ethernet network
» The benefits of iSCSI
• Enable SMB to build SANs with standard equipment such as Gigabit
Ethernet switches and network interface cards (NICs)
• Avoid the high entry costs and specialized knowledge for Fiber Channel
» iSCSI SAN
• An iSCSI SAN accesses and transfers data in blocks
• Each connected server sees the remote storage as a local drive
» How iSCSI works
• iSCSI networks use two types of nodes:
o Initiators
o Targets
- the hosts requesting data from storage, and
- the storage holding data
• Users can install free initiator software, widely available from sources
such as Microsoft and standard Linux OS distributions
© .1996-2004 NETGEAR® . All rights reserved
19
NAS vs. iSCSI SAN
» Both utilize TCP/IP Network
» A NAS is a single storage device that operates on data files
» An iSCSI SAN that operates on disk blocks

FAQ’s
Can I migrate my disks from my existing ReadyNAS to the Pro?
No. The RAID format has changed for the Pro to take better advantage of the Pro architecture.
What’s the difference between X-RAID and X-RAID2?
First, the format is different, so they are incompatible. Second, like X-RAID, X-RAID2 allows
both horizontal (by adding disks to slots) and vertical (by replacing disks with higher capacity
disks), however, unlike X-RAID, X-RAID2 does not require replacing all the disks for vertical
expansion before expanding the volume. X-RAID2 can expand as soon as the 2nd disk is
replaced. With the Pro having 6 drive bays, this allows the expansion to occur without having to
replace out all 6 slots.
What’s the difference between ReadyNAS Pro Pioneer Edition and Business Edition?
The ReadyNAS Pro Business Edition comes pre-configured and pre-installed with disks and
includes features suitable for the business environment, such as Active Directory, snapshot, FlexRAID (including RAID 6), and iSCSI. The Pioneer Edition is available only as a diskless model
for the advanced home enthusiasts to enjoy the accelerated performance of the ReadyNAS Pro at
an affordable price.

34
FAQ’s
iSCSI is supported with the ReadyNAS Pro Business Edition?
Yes, with the iSCSI add-on for the Business Edition, (available shortly). Note: This will also be
available as a paid add-on for the Pioneer.
Can I update from Pioneer Edition to the Business Edition?
Not at this time.
How do you power of the ReadyNAS Pro?
Push the Power Button Twice
What happens if I hold the front power button down continuously for 5 seconds while the
unit is powered on?
The ReadyNAS Pro is similar to a standard PC, where holding the power button down for 5
seconds abruptly shuts the unit off (the same as pulling the power plug!). *DO NOT* power the
unit off this way.
© .1996-2004 NETGEAR® . All rights reserved
35
FAQ’s
If the ReadyNAS Pro hangs on bootup after an abrupt power outage, what should I do?
Use the physical power switch on the back of the unit to power off and on the unit.
Can I use the add-on modules for the NV+/1100 on the ReadyNAS Pro?
No, the Pro is based on an Intel chipset and requires add-on modules specifically compiled for this
platform.
