Empowering Your Software-Defined Transformation
What’s the SDDC About?
I need a datacenter with : • 6 servers(2 CPU, 10G
NICx2 2TB HDD) • 1G network with IP
address 192.168.x.x • 100TB SAN/NAS
storage

Current Situation – Hard to Scale Scale-Up
Performance
Disk I/O performance bottleneck as scale-up disk capacity
Performance Performance
Current Situation – Application Silo
1000 IOPS RAID 5 100 TB SAN
APP 3
500 IOPS RAID 5 90 TB SAN
1000 IOPS RAID 6 30 TB NAS
APP 2
500 IOPS RAID 6 20 TB NAS
5000 IOPS RAID 5 100 TB SAN
APP 1
1000 IOPS RAID 5 20 TB SAN
Different storage requirement from application create Storage Islands.
Current Situation – Complex Design for Durability

APP 2 APP 3
Datacenter 2 Datacenter 1
Remote Sync
Complex data durability design due to application requirement introduced more storage island and high OPEX
Customer's Behavior
• Purchase a new storage for a new application
• New application require a different storage requirement
• Storage type(NAS, SAN)
• Performance
• Durability
• Purchase a more powerful storage when existing workloads grow
• Require migrate data to new storage
• Cause service downtime
• Complex storage infrastructure management and design for SLA
• Different storage island and different availability design for each vendor
• Labor intensive for resource provisioning, workload changes and HW life cycle management
IT Challenge – Quick Response to Business demand
• Different Workload different storage requirement
• Performance
• Capacity
• Access protocols
• Recovery
• Future expansion
• ……
• Ends up building another storage for new workload demand
• Purchase new storage requires longer purchase process
IT Challenge - Time-consuming storage migration
● Costly array replacements
● Time-consuming data movement time
● Service down time for data migration
● Extra metadata/data migration server
New storage systems
Legacy storage systems
Metadata / Data
migration server
Applications server
IT Challenge – Storage Utilization
• In average, datacenters storage utilization are lower than 50%
Over half of the free capacity remains idle and unused, even while requisitions for new storage systems continue to be filled.
IT Challenge – Storage Management
• Current storage infrastructure are mixed with
• Various storage vendor
• Various storage type
• Various storage design
• Various storage with different performance
• Various storage management system
• Different age of storage
What is HCI
• Hyper-converged infrastructure (HCI) is a software-defined IT
infrastructure that virtualizes all of the elements of conventional
"hardware-defined" systems. HCI includes, at a minimum, virtualized
computing (a hypervisor), a virtualised SAN (software-defined
storage) and virtualized networking (software-defined networking).
Why HCI
• Agility
• Can I use the storage capacity on compute servers?
• Can I use the compute power from storages?
• More efficient to bring storage closer to application
• Reduce the network latency
• Disk is slow, the compute resource can be re-used
Problems of HCI
• Even storage is closed to application but cross server data protection
still introduce extra latency(network).
• Applications need a “external” share storage not only VM disks
• Applications require different type of storage and SLA
What is Software Composable Infrastructure
• In composable infrastructure, compute, storage, and networking
resources are abstracted from their physical locations, and can be
managed by software
Why SCI not HCI?
• Flash become affordable and it’s too fast that consume all CPU
resources to drive it
• What about network latency?
• RDMA, RoCE, iWAP
• 25G, 40G, 100G and 200G
• NVMeoF
• Network disk can runs almost the same with local disk
Challenge of SCI
• Applications require external share storage
• Block, file and object
• New architecture to replace legacy
• Workload that has different performance and SLA requirement
• SDS vendor lock-in

Ceph FileStore VirtualStor
Extreme
● Write amplification (WA) is an
undesirable phenomenon with flash
where the actual amount of data
physically written to the media is a
multiple of the logical amount
intended to be written. It will make
SSD life reduced.
● Compared with other SDS like Ceph,
VirtualStor Extreme significantly
minimize WA to 1.05. Almost 7X of
SSD life than other SDS.

SSD life, Capacity and Performance prediction
• Monitor SSD health and issue early
warning before the SSD wears out.
• Analyze the historical capacity usage
and performance data to predict when
space may be depleted.
• Through SSD life, capacity and
performance prediction, storage admin
can proactively plan the replacement
and expansion beforehand.
