. 8.3 USABLE SPACE VS. WRITE PERFORMANCE TRADE-OFFS To refine application performance, Seagate allows customizing the ratio of usable data to write acceleration area. By increasing the amount set aside for writes in "maxperformance" mode, the Seagate X8 Accelerator drive is able to sustain an even higher write workload at the cost of reduced usable capacity. Conversely, by decreasing the amount set aside for write acceleration in "maxcapacity" mode it is possible to allow more user data to be stored on the device but with lower sustained write performance.. X8 Accelerator partitioning reduces the attainable performance for each NOTE individual partition to one-half of the maximum drive performance. 8.4 CONFIGURING MULTIPLE PARTITIONS The example below shows how you would use the vgc-config.exe utility to create partitions. Once you create the partitions the Device Manager will automatically refresh itself to display the new partition information as follows: Note that once you create the partitions they are in the 'Offline' state, as depicted in the Disk Manager display above. You can then use the Disk Manager to bring the disk online and to initialize it. Also, 500GB and 1100GB devices do not support split partition. To set SAN policy you could use "SAN command in disk part". If SAN policy of system set as "OnlineAll", it will automatically bring the volumes online. See the following screen shots for an example.
