The Celerra VG8 Gateway Server system is a consolidation of file-based servers with NAS (NFS, CIFS) applications configured in an 1+1 High-Availability cluster. The servers deliver network services over high-speed Gigabit Ethernet. The cluster tested here consists of one active Data Mover that provides 8 Jumbo-frame capable Gigabit Ethernet interfaces and one stand-by Data Mover to provide high availability. The Celerra VG8 is a gateway to Shared Storage Array Symmetrix VMAX. The Symmetrix VMAX is a storage architecture using 4 VMAX engines interconnected via a set of multiple active 4 Gbit/s FC HBAs connecting to the fabric.

|This set of 304 FC disks was divided into 152 2-disk RAID1 pairs, each with 2 LUs per drive, exported as 304 logical volumes. All data file systems reside on these disks.||304||44.5 TB|
|This set of FC disks consists of 4 2-disk RAID1 pairs, each with 2 LUs per drive, exported as 8 logical volumes. These disks are reserved for Celerra system use.||8||584.0 GB|
|Number of Filesystems||4|
|Total Exported Capacity||44384 GB|
|Filesystem Creation Options||Default|
|Filesystem Config||Each filesystem was striped (32KB element size), across 38 2-disk RAID1 pairs; for fs1 fs2 fs3 and fs4 this consumed a total of 304 logical volumes|
|Fileset Size||16742.5 GB|
The drives were configured as 152 2-disk RAID1 pairs. 38 2-disk RAID1 pairs were assigned to each Symmetrix VMAX engine. Each RAID1 pair had 2 LUs created on it, of which only 1 LU was used per RAID1 pair. 4 stripes were created, one per 38 RAID1 pair group with a stripe element of 32KB. 4 file systems were created, 1 per stripe. A Symmetrix VMAX engine provided access to the drives of 1 file system. All 4 file systems were mapped on the Celerra Data Mover. All 4 file systems were shared by the Celerra Data Mover. Each client mapped all 4 file systems through each network interface of the Celerra.
|Item No||Network Type||Number of Ports Used||Notes|
|1||Jumbo Gigabit Ethernet||8||This is the Gigabit network interface used for the active Data Mover.|
All Gigabit network interfaces were connected to a Cisco 6509 switch.
An MTU size of 9000 was set for all connections to the switch. Each Data Mover was connected to the network via 8 ports. The LG1 class workload machines were connected with one port.

Each Data Mover has one physical processor.

|Grand Total Memory Gigabytes||280|
The Symmetrix VMAX was configured with a total of 256 GB of memory. The memory was backed up with sufficient battery power to safely destage all the cached data onto the disk in the event of a power failure.
4 CIFS file systems were used. Each RAID1 pair had 2 LUs bound on it. Each file system was striped over half of the logical volumes. The storage array had 8 Fibre Channel connections, 4 per Data Mover.
The system under test consisted of one Celerra VG8 Gateway Data Mover attached to a Symmetrix VMAX Storage Array with 8 FC links. The Data Movers were running DART 188.8.131.52. 8 GbE Ethernet ports on the Data Mover were connected to the network.
Failover is supported by an additional Celerra Data Mover that operates in stand-by mode. In the event of the Data Mover failure, the stand-by unit takes over the function of the failed unit. The stand-by Data Mover does not contribute to the performance of the system and it is not included in the components listed above.

All filesystems were mapped on all clients, which were connected to the same physical and logical network.
Each client has the same file systems mapped from the active Data Mover.
Failover is supported by an additional Celerra Data Mover that operates in stand-by mode. In the event of the Data Mover failure, the stand-by unit takes over the function of the failed unit. The stand-by Data Mover does not contribute to the performance of the system and it was not included in the components listed above.
