CloudStack Tech Talks - Storage 2. Guaranteeing Storage Performance
in CloudStack CloudStack 3. Who am I ? Midori Oge / @star76popin
Chairman of Japan CloudStack Users Group Systems Engineer,
SolidFire Inc. 4. The world as it is.. Processor speeds and network
bandwidth have been able to keep pace with new workloads
requirements CPU Many workloads due to virtualization technology
and cloud computing / How's the STORAGE? 5. The world as it is..
HDD performance had remained almost unchanged increasing
OpEx(power, rack space) proprietary hardware complicated design and
operation (RAID sets, manage logical Volume and LUNs) can't catchup
the needs of cloud and unpredictable scaling running many kinds of
storages (dierent solutions for dierent workloads) HDDI/O ()
(RAID,,LUN) 6. beginning of the innovation 2 - Hot/ActiveFlash -
Cold/Static - HDD SAS Disk Bipolarization of Storage solution -
Hot/Active data for critical applications is stored in Flash
storage - Cold/Static data for backup is stored in cost/capacity
optimized storage - HDD SATA Disk is expected to decrease in these
years Software Dened Flash prices are reduced Flash 7. Technical
trend for cloud computing de-duplication, compression,
thin-provisioning multi-tenant scale-out improving availability by
data distribution fault detection, self-healing integrated for
cloud(CloudStack, OpenStack), API-driven automation (CloudStack,
OpenStack)API 8. Storage Types in CloudStack Primary Storage
Secondary Storage for Boot Disks and Data Disks NFS, iSCSI, Fibre
Channel, CIFS (if performance is needed without using HA, you can
choose local storage) Scope: Cluster or Zone for Templates, ISO
Images, Snapshots NFS, CIFS Swift/S3(w/NFS) Scope: Zone What kind
of STORAGE do we choose? 9. What type of storage do we choose?
Secondary Storage - using low-cost storage or object storage(e.g.,
swift) (swift) Primary Storage - Storage performance leads to VM
performance(meet the requests of IOPS/Latency) VM(IOPS/Latency) -
Lose VM due to Primary Storage fail Primary StorageVM Need
"Guaranteed Performance !!" 10. Guaranteed Performance (QoS) both
MIN and MAX is important in QoS QoSMINMAX2 Form Mixed Workloads MIN
protect the important volume Volume MAX limit the IO of monster VM
