BizTalk BizTalk performance SQL SQL performance Storage Storage performance ”But I’m a Developer!!! I am not meant to know about this stuff. The X department take care of that.”

”the BizTalk guy””the SQL guy””the Storage guy” I like to order a SQL cluster with 12 disks... I like to order 12 LUNS... I’ll let him share the disk array with the SAP system..

Data Data Data Data

Base casting Spindle Slider (and head) Actuator arm Actuator axis Actuator SATA interface connector Power connector Flex Circuit (attaches heads to logic board) Platters Case mounting holes Cover mounting holes (cover not shown) Performance: IO Per Second (IOPS)

No moving parts! Performance: Read IO Per Second (IOPS) Less writes! 1500 Write IOPS

By partitioning < 50% of the disk, the data will be allocated on the outer track, making all reads and writes done from outside edge. Example: A 1 TB disk with an access time of 12 ms at 200 IOPS ~ throughput of 100 MB/s A 300 MB partition from the same drive might end up with an access time of 6 ms at 300 IOPS ~ throughput of 200 MB/s * *For sequential workloads this can be even higher Partition

Latency (response time) Reads are in the 5-6ms range and writes 1-2ms with spikes to 20-30ms during checkpoints. Checkpoint Activity These are short-lived burst of writes with a large amount of outstanding I/O requests. It is normal for latency to increase a bit during this operation. Hosting BizTalk databases on poor performing disks, a SQL checkpoint can cause a message processing drop. High throughput storage for SQL Server data and log files is absolutely critical to BizTalk performance.

”Disk Array” RAID 5RAID 10 LUNLUN LUNLUN ”the Storage guy” I’ll let him share the disk array with the SAP system.. Key Takeaway: There might be a conflict of interest…

RAID 1 (Mirroring) + Total data redundancy - Slow(er) - Expensive RAID 5 (Distributed parity) + Cost efficient + Fault-tolerant + Good performance - The extra time required to calculate and store parity degrades the write performance RAID 10 (1+0) (Mirroring + Spriping) + Total data redundancy + Increased write transfer rate - Expensive RAID 0 (Striping) + Very fast - No redundancy * New generation SAN technology tends to use huge caches so RAID choice is becoming unimportant
