DVUM Performance Matrix

DVUM Tier Range Max CPU (vCores) Max Memory (GB) Max tempdb / buffer pool space Max tempdb / buffer pool performance Max IO Performance (128KB IO) Max BW Performance (16KB IO)
1 4 32 1 x 937 GB 100K IOPS 18K IO 150MBps
2-3 8 64 1 x 1875 GB 100K IOPS 36K IO 300MBps
4-5 12 96 1 x 3750 GB 150K IOPS 40K IO 450MBps
6+ 16 128 1 x 3750 GB 150K IOPS 40K IO 600MBps

 

Notes:

  • IOPS and storage throughput assume a 75% Read / 25% Write distribution. Performance may vary based on workload.
  • Working database servers have resources allocated based on actual usage demand analysis up to the Max values defined in the table above.
  • Each SDR replicate server receives up to 8 vCores and 32 GB memory, based on actual usage demand analysis.
  • If Serverless database architectures are being used a comparable allocation of system resources will be provided at 1 ACU per 1GB of Memory,
  • Maximum size for a single database system is 16 cores and 128GB memory

Example Model: A Customer purchases 7 DVUM and wishes to operate two environment tiers: Tier A and Tier B. The Customer can allocate 4 DVUM to Tier A, which places it in the 4-5 DVUM tier (entitled to 12 vCores, 96 GB memory). The remaining 3 DVUM can support the Tier B instance under the 2-3 DVUM tier (8 vCores, 64 GB memory). To increase Tier B to 12 vCores and 96 GB memory, the Customer must purchase an 8th DVUM to qualify for the 4–5 DVUM tier.
