In line with announcements from IBM on May 19th, we published the latest versions of these IBM Redbooks FlashSystem Product Guides:
Here are 5 interesting facts to know about the latest release of IBM FlashSystem 840:
1. FlashSystem 840 includes 4 flexible interface types and is easy to integrate into your existing infrastructures:
- Fibre Channel: Up to 16 ports of 8 Gbps or eight ports of 16 Gbps
- Fibre Channel over Ethernet (FCoE): Up to 16 ports of 10 Gbps
- iSCSI: Up to 16 ports of 10 Gbps
- InfiniBand (QDR): Up to eight ports of 40 Gbps quad data rate
2. Implement FlashSystem 840 when speed is critical.
FlashSystem 840 is designed with IBM MicroLatency™ to help speed up application response times, so organizations can use real-time data to make faster strategic decisions. Up to 1,100,000 IOPS, up to 8GB/s bandwidth and latency as low as 135us/90 us (read/ write).
3. FlashSystem 840 is highly scalable
The introduction of a low capacity 1 TB flash module allows IBM FlashSystem 840 to be configured in capacity points as low as 2 TB and as high as 48 TB in its compact 2U enclosure. Many granular capacity points are possible due to the three choices in flash module capacity: 1 TB, 2 TB, and 4 TB.
- RAID 0 configurations have capacity points of 2 TB, 4 TB, 6 TB, 8 TB, 10 TB, 12 TB, 16 TB, 20 TB, 24 TB, 32 TB, 40 TB, and 48 TB
- RAID 5 configurations have capacity points of 2 TB, 4 TB, 6 TB, 8 TB, 10 TB, 12 TB, 16 TB, 20 TB, 24 TB, 32 TB, and 40 TB
Note: These modules can be either 1 TB, 2 TB or 4 TB, and different flash module sizes cannot be intermixed in the same IBM FlashSystem 840 chassis
4. FlashSystem 840 is extremely easy to service
Slots for up to 12 flash storage modules (1 TB, 2 TB, or 4 TB) are hot-swappable by way of tool-less front panel access. If a flash module failure occurs, critical customer applications can remain online while the defective module is replaced.
With two redundant hot-swappable canisters, IBM FlashSystem 840 enclosures include two battery modules and two power supplies, which are all redundant and hot-swappable. All components are easily accessible by way of the front or rear of the unit, so IBM FlashSystem 840 does not need to be moved in the rack. This makes servicing the unit easy.
5. FlashSystem 840 supports concurrent code loads and maintenance
To further minimize downtime, FlashSystem 840 supports concurrent code load and maintenance for non-disruptive firmware upgrades. This enables customer applications to remain online during firmware upgrades to all components, including the flash modules.
