SVC 6.2 update

– Providing this will require a decision of either SAS-attached SSD or 10 GbE for each node
New engines may be intermixed in pairs with other engines in SVC clusters
Solid State Drive support (up to four per SVC node) enabling scale-out high performance SSD support with SVC 10 Gb Ethernet support for 10 Gb iSCSI host attachment and future FCoE support
– Mixing engine types in a cluster results in volume throughput characteristics of the engine type in that I/O group
Cluster non-disruptive upgrade capability may be used to replace older engines with new CG8 engines Replaces the SVC 2145-CF8 engine
Increases flexibility in using FlashCopy Enables straightforward replication of backup copies to remote location

FlashCopy Target as Remote Mirror Source
Enables the target of a FlashCopy operation to be a Remote Mirror source volume
– Comparable to similar DS8000 capability
– Four times previous limit – Requires 8GB extent size
Enables larger SVC customers to plan with confidence for future growth Larger configurations support greater virtual storage consolidation and so greater benefits for customers

Confidential until announcement
SVC now supports RAID protection for internal SSDs SVC Easy Tier function supports both internal SSDs and SSDs in virtualized disk systems
– Helps improve storage system performance – Helps reduce cost by automatically placing only most active data on SSD, reducing need for SSD capacity
Easy Tier Support for Internal SSDs
SVC 6.2 restores support for internal SSDs with SVC Delivers extremely high performance capability
– Up to 50,000 IOPS per SSD
Easy Tier can improve throughput up to 200% and reduce response time up to 60% with only about 10% of total capacity on SSD

Real Time Performance Statistics
What this is
Gathers system level performance statistics (CPU utilization; port utilization and I/O rates; volume and MDisk I/O rate, bandwidth, latency) in real time with sampling rates down to 5 sec. Provides a snapshot view for immediate monitoring, with limited capture of performance history (~5 min.)

VMware vStorage APIs for Array Integration (VAAI)
What this is
Integration with vStorage API’s to enable VMware control over typical storage operations in a virtual server environment Includes the following operations: – Optimized VM provisioning (Write Same)
Avoids zero regions for optimized data transfer
–Байду номын сангаас
Why it matters
Improve performance and efficiency in deployment and management of virtual volumes Offload I/O from production virtual servers to improve application performance

Why it matters
A background copy of the FlashCopy targets allows customers to use a lower bandwidth link for remote copy Allows to continue to focus on cost efficiency with higher network performance by offering 10 Gb iSCSI host attachment In the future, acceptance of higher latency on the link can lead to support for distances greater than 8,000km
