Product ComparisonThe following information includes the current NV+ and 1100 products, as well as the x6/600 and 1000s legacy products.


SAN versus NAS, Key difference?

» Many file systems are used including Linux, NTFS, FAT

» Almost any client can directly access the NAS using CIFS/SMB

» Volumes mounted as network volumes

» No possible driver conflicts on the client system, since no drivers are required

» Uses a proprietary SAN file system (example SFS)

» Requires a dedicated driver on the client system

» Volumes mounted as “physical drives” on client

» Client driver may conflict with other software on client PC

NAS SAN

Module


General Specs and Performance» Memory is

upgradeable per HCL specifications

» Performance is based on benchmarks using IOMeter

» Performance is measured on a gigabit network with jumbo frames


Disks/Volumes Supported and Networking

» Both current models support the same volume types

» The 2nd network interface on the 1100 is not for redundancy or “teaming”/load balancing

» Wireless networking is supported by using USB wireless adapters as listed on the HCL

» The ReadyNAS cannot be connected to a workstation or server to act as a USB hard drive


Management, Monitoring, Services, Security

» UPS monitoring requires a USB UPS device from the HCL

» Email alerts require configuration in Frontview web interface

» NFS is currently only supported over UDP, not TCP

» Domain security mode requires an already established domain or active directory environment


Backup

» EMC Insignia handles support for the Retrospect application

» The integrated backup manager is configured from Frontview

» USB drives formatted as HFS(Mac OSX format) are not supported


Network media streaming» All ReadyNAS products

support the following media streaming protocols: Slimserver, iTunes, UPNP-AV

» Devices compatible with these protocols are compatible with the ReadyNAS, the HCL has a basic list of devices

» Not all network media devices require the above protocols and will use a standard file protocol instead


Physical Dimensions and Power Usage

» The 1100 is a rackmount 1U form-factor

» The 1100 does not require 4 post mounting with rails

» Power consumption is far less than traditional workstation or server

Business VS. Home usageThe following portion will detail the key differences and let you know which products are suitable for either a business or home environment


ReadyNAS NV+ in the Home and Workplace

» Small footprint for easy placement

» Nearly quiet cooling system» Easy to use LCD status

display

Home Workplace» Quiet cooling does not

require placement in server room

» Transportable unit allows for easy movement depending on user’s needs

» Small size means multiple units can be placed throughout office for usage in small workgroups


ReadyNAS 1100 in the Home and Workplace

» Extremely loud cooling system may require

» placement in dedicated equipment closet.

» Dual ethernet rarely needed for home use

» Most users do not have server rack for installation

Home Workplace» Easy installation into

existing server rack» 1U half-depth form-factor

allows for back-to-back installation in 4 post server rack for increased storage

» Dual ethernet supports use on multiple networks

» Modular chassis allows for easy maintenance without removal from server rack

RAID (Redundant Array of Independent Disks). A collection of disk drives that offers increased performance and fault tolerance. There are a number of different RAID levels. The three most commonly used are 0, 1, and 5

What is RAID?


What is Raid 0

· RAID 0: Striped Set (2 disks minimum)

without parity: provides improved

performance and additional storage but no

fault tolerance from disk errors or disk

failure.

http://en.wikipedia.org/wiki/Data_striping


» · RAID 1: Mirrored Set (2 disks minimum) » without parity: provides fault tolerance » from disk errors and single disk failure.» Increased read performance occurs» when using a multi-threaded operating» system that supports split seeks,» very small performance reduction » when writing. Array continues to » operate so long as at least one drive » is functioning.

What is Raid 1

http://en.wikipedia.org/wiki/Disk_mirroring


What is Raid 5

» · RAID 5: Striped Set (3 disk minimum) with Distributed Parity: Distributed parity requires all but one drive to be present to operate; drive failure requires replacement, but the array is not destroyed by a single drive failure. Upon drive failure, any subsequent reads can be calculated from the distributed parity such that the drive failure is masked from the end user. The array will have data loss in the event of a second drive failure and is vulnerable until the data that was on the failed drive is rebuilt onto a replacement drive.

http://en.wikipedia.org/wiki/Parity_bit

FlexRAID and X-RAID(The ReadyNAS supports two different types of RAID)


Flex-RAID

» Flex-RAID is “FLEXible”• it supports industry standard RAID levels 0, 1, and 5• up to 4 volumes are supported (2 partitions from each drive can be used)• disks can be manually specified as being a part of the RAID volume• hot spares can be specified for RAID 1 and 5

» Utilizes disk striping in RAID 0 and 5• striping provides good performance when data is scattered (i.e. small files)• when two disks fail, almost impossible to recover data• parallel access allows better handling of disk fragmentation

» Expansion supported via additional volume(s)• each disk can be replaced with a larger capacity one• new RAID volume can be created using unused space from new disks

» RAID format compatible with Linux MD RAID• allows for data recovery using Linux


FlexRAID: RAID-0,1, and 5

» FlexRAID allows users to specifically choose which RAID type they want

» FlexRAID allows for using a “hot-spare” for automated failover during drive failure

» FlexRAID mode does not allow for expansion by adding more drives


What is X-RAID

X-RAID is our proprietary RAID technology, that allows automated volume management and expansion

» X-RAID is “eXpandable”• X-RAID volumes can be started with 1, 2, 3 or 4 drives, with additional drives added at a

later time. (horizontal expansion)• X-RAID allows users to begin with smaller drives, and then upgrade later to larger drives

and gain additional volume capacity (vertical expansion)» X-RAID is similar to RAID 5 in that parity data is used to recover in the event of a drive

failure» X-RAID volumes can be started with 1, 2, 3 or 4 drives, with additional drives added at a

later time. (horizontal expansion)» X-RAID allows users to begin with smaller drives, and then upgrade later to larger drives

and gain additional volume capacity (vertical expansion)» X-RAID allows expansion without having to shuffle data between systems


X-RAID Expansion – what the user sees

» “Horizontal” expansion• Start with a one-disk volume• Add 2nd disk, volume becomes

redundant (2nd disk mirrors 1st)• Add 3rd disk, let it initialize and

reboot -- volume capacity doubles while preserving volume content and redundancy

• Add 4th disk, let it initialize and reboot -- volume capacity triples while preserving volume content and redundancy

100 GB 100 GB 100 GB

Total Capacity: 100 GB200 GB300 GB


X-RAID Expansion – what the user sees

» “Vertical” expansion• Start with a volume of 2 or more

disks• Replace each disk with a larger

one, let it initialize and sync !before! adding the next drive

• Reboot to grow volume size to utilize newly added space while preserving volume content and redundancy

Frontview, RAIDar, and RAIDiator


Frontview


Frontview» Frontview is the name for the web interface allowing

administration and management of the ReadyNAS products» Frontview configuration is the same on all products» There is a setup wizard available for first time users» Advanced users may switch to an advanced mode allowing for

additional configuration options» Frontview allows for configuring network settings, security mode,

user accounts, available shares, and share permissions.» Frontview also has detailed information regarding the status of

the unit and volume health


RAIDar

» RAIDar is a simple monitoring tool allowing users to monitor multiple NAS units in a single application

» RAIDar is used in the initial setup to indicate volume type during a factory default operation

» Color coded status indicators will let administrators know at a glance if an issue has arisen, such as a failed fan or hard drive


RAIDiator (operating system)

» RAIDiator is a customized version of Linux allowing for far more security than available on Windows based NAS units.

» RAIDiator is the same on all ReadyNAS products» RAIDiator can be updated from within Frontview» Presently Frontview is the only means to access RAIDiator, SSH

access is planned for a future update.
