3 Vorteile von Spectrum Scale RAID im Vergleich zu traditional RAID
Faster disk rebuilds• Disk rebuilds are in minutes vs hours/days because of de-clustered RAID
Higher storage resiliency• uses erasure coding with upto 3 parity blocks and can survive 3 disk failures with only 27%
overhead in capacity compared to 200% overhead with 3-way replication• uses fault domains to layout disks in such a ways that it can survive entire disk shelf failures • uses disk hospital to pro-actively identify sick drives (disks with bad sectors or media errors)
and either a) replace the disk or b) fix any bad data from parity
End-to-end data integrity• Spectrum Scale RAID maintains checksum of data blocks from the client to the blocks
on the disk and validates at every point, eliminating the chances of silent data corruption or data loss

20 physical disks / 1 Declustered array
Checksums und Version numbers
Checksums in data trailer detects corruption
Checksums don’t detect stale data if it is not also stored elsewhere in metadata
• Old data matches old checksum
Storing strong checksums in metadata adds space constraints• Instead store version numbers in metadata to detect dropped writes
GPFS Native RAID uses both checksums and version numbers to protect user data
End-to-end checksums• Write operation
– From compute node to IO node
– From IO node to disk
• Read operation– From disk to IO node
– From IO node to compute node

Capacity is approximate based on 8+2P, single shared Data and Metadata pool. Performance is based on standard IOR benchmark, sufficient clients & network performance etc.Performance shown includes reduction from peak performance measured in testing, as an allowance for variations in real world deployments.
Achievable performance will vary from the figures shown, based on workload, network, and other factors outside of IBM’s control.

IBM Elastic Storage Server: Hybrid Models
ESS Hybrid Models: GH12, GH14 and GH24• Provide combination of flash and HDD storage
tiers in one ESS building block• Combine all-flash performance with GLxS
capacity• Use cases:
– Single system for both metadata services and high density– Use the Flash for Burst Buffer storage and have Spectrum
Scale migrate data to high density spinning disk– Use Scale to automatically manage data location between
flash and disk based upon heat maps and policy– Handle multiple kinds of workloads such as video and
analytics in the same environment

ESS Easy Upgrade: Add Low-Priced Capacity to Existing ESSes
Business Issues• Keep ahead of data growth
• Additional capacity
• Additional performance
• Constrained budgets
• New workloads
• Avoiding downtime
• Fit within data center facility constraints
The Solution• Increase performance and capacity
• Increase from 1 to 2, 2 to 4, or 4 to 6
HDD enclosures
• For example, 2 to 4 enclosures,
while doubling the capacity and bandwidth
• Increase from 1 to 2 or 2 to 4 SSD enclosures,
while doubling the capacity and the bandwidth
• Plug and go:
• No downtime
• Automatically rebalances the data
onto the new storage racks
• No need to dump and reload the data
• Attach new storage enclosures
to Power servers in existing ESSes
Low prices
No additional ESS Power servers or networks
