Detailed explanation of example 1.
Example Large StorNext configuration

showing DS5300‟s with Fibre Channel and/or SATA disk for Data and a separate

DS5020 for Meta Data and Journal. These examples are representative only and should not be seen as restrictive. The idea is
to use our knowledge of these products to craft solutions with the proper performance and resiliency characteristics to meet
customer needs and budget concerns.

DS5020 for Journal and Meta Data with FC drives



This is an example configuration only



RAID 1 for StorNext Meta Data



RAID 1 for StorNext Journal



Add additional RAID 1‟s rather than growing to RAID 10 for performance reasons.



Controller A can see all client and MDC host ports but not Controller B



Controller B can see all client and MDC host ports but not Controller A

DS5300’s with FC and/or SATA for Data



This is an example configuration only



Multiple RAID 5 (both 4+1 and 8+1) RAID Arrays for StorNext data



Multiple RAID 6 (both 4+2 and 8+2) RAID Arrays for StorNext data may also be desirable in some situations



Controller A can see all client and MDC host ports but not Controller B



Controller B can see all client and MDC host ports but not Controller A

Mixed Clients

– SAN Zoning



Clients have single dual ported HBA‟s with connections into a redundant switched network and zoned to be
able to see both Controller A and B



MDC‟s have dual dual ported HBA‟s with connections into a redundant

switched network and zoned to be

able to see both Controller A and B

All Storage Configurations for StorNext environments



AVT should be set OFF for all partitions and host types



For MAC Clients There is not currently a host type definition for MAC Clients (there will be in the future).
Because of this a work-around has been developed for use until the MAC host type is available.
1. Set host type LNXCLVMWARE
2. Set TPGS on(via a provided script)



For Linux Clients (and VMware servers)
1. If no MAC clients exist, then the host type LNXCLVMWARE should be used, as this host type has AVT

disabled.

2. If MAC hosts exist in the environment, Linux clients (and VMware servers) should use the host type

LINUX,

3. Insure that AVT is turned off for all host regions, including LINUX (via a provided script). This can be

done by checking the bottom of the complete (all tab) system Profile.



For mixed environments:
1.

Create a Host Group for all MDC‟s and Clients that will access the StorNext file system. There is no Host
type associated with Host Groups (only individual hosts)

2. Assign multiple host types to this group.
