This process is intended to rank categories in order of importance to the product. First, please take a few moments to review the categories and definitions below to ensure you clearly understand the scope of the definitions. Use the Category Ranking table to rank the categories in order of importance to the product (1 being most important, 9 being least important). This should be done by first ranking in groups of high, medium and low (3 of each).
Next, use the Spider Chart Rankings table to rank each category in order of importance given design decisions and trade offs made by engineering. 5 is the highest ranking, 1 is the lowest ranking.
When rationalizing rankings on the spider chart, please consider the platform being ranked against the entire Dell EMC portfolio to properly rank the highest values. It is not required that there be two 5's, please rank accurately by engineering decisions and design tradeoffs as well as rationalizing against the entire Dell EMC portfolio (For example, in the category of RAS the VMAX is considered the flagship product worthy of a 5, whereas the VNX, while excellent in the RAS category, is most likely a 4 due to design tradeoffs and relative ranking to the VMAX). YOU MAY USE EACH NUMBER NO MORE THAN TWICE IN THIS SECTION (no more than two 4's , two 2's etc.)
|$/IOPS||Low dollar cost per storage IOPS.|
|$/GB||Low dollar cost per gigabyte of storage.|
|LATENCY||The time it takes from the time the array receives the request until it services the request.|
|AGGREGATE IOPS/GBPS||The raw throughput the array can service in a typical configuration.|
|QoS||Defined by the ability to provide priorities, thresholds, reservations, scheduling and external manageability such as orchestration or automation tools.|
|RAS||Reliability, availability and serviceability. How reliable is the array in terms of data protection; how resilient is the array when a fault occurs; how simple and how quick is it to repair the array if a failure occurs.|
|SCALES DOWN||What is the cost of entry for a viable configuration? How low of a price point (average street price) can the system be delivered at?|
|Ability and ease to add additional controllers in a scale out architecture. The ease of management as storage processor count increases. Does management become more complex as additional SP's/Systems are added?|
|SOLUTION INTEGRATION||How well does the system integrate into a solution? How "invisible" is the array capable of being when integrated into the environment?|
Initially, group into high, medium and low. Once categorized, rank within those categories of H, M and L (Highs 1-3, Mediums 4-6, Lows 7-9). Once that is done, compare 3 vs 4 and 6 vs 7 to provide an additional checkpoint to ensure correct order.
DO NOT refer to this table while filling out the spider chart rankings table. Once you have completed the spider chart rankings table, you should then review and compare category rankings to the spider chart to determine if any discrepancies exist.
|Manageability and Scale Out|
Rank each category in order of importance to the product (5 being the most important, 1 being the least important). Consider engineering decisions and design tradeoffs when ranking. Please do not use any ranking number more than twice.
