Introduction The VMA-series Memory Arrays (VMA) are external solid state Flash memory storage arrays. VMA arrays provide scalable solid state capacities with higher performance and more reliability than traditional magnetic media.

• • HP is not supporting connectivity to all the host operating systems mentioned in the manuals; only those listed in Table 1 have been fully tested to the level of HP quality and are considered supported. Only the VMA3205 (5TB) and VMA3210 (10TB) models are supported; other models with other capacity and memory module capacities are not supported by HP at this time.

VMA-series Memory Array: General Recommendations The following are general recommendations for getting optimal performance with the HP VMA-series memory arrays. Alignment of data transfer I/O block sizes The internal flash addressing of the VMA is based on 4K (4096) byte boundaries. Read or write requests that do not begin on a 4KB aligned target block address or are of I/O sizes not a multiple of 4KB may suffer a performance impact. Write performance is more seriously affected by non-4KB alignment.

Setting Date and Time It is recommended to set the correct date and time on your host server and array when it is initially installed and configured. Setting the correct date and time will help with correlation and analysis of host server and array events if a problem is reported.
