Well, it's Tuesday, so that means IBM announcements!
We had so much announced, that I will just cover the disk systems today, and deal with tape systems and software tomorrow.
- IBM System Storage DS8000 series
IBM continues to invest heavily in its strategic [DS8000 series].For [existing 2107 machines], IBM's new DS8000 microcode supports:
- 1 TB 7200 rpm Serial ATA (SATA) Disk Drives
Now that IBM XIV has proven that 1TB SATA are safe for high-end tier-1 enterprise class use, we extended DS8000 support to include SATA support also. DS8000 supports RAID-6 and RAID-10 for these.
- Intelligent Write Caching
IBM Research conducts extensive investigations into improved algorithms for cache management. Intelligent Write Caching boosts performance for both temporal and spatial locality.
- Remote Pair FlashCopy®
This allows you to FlashCopy volume A to volume B, with Volume B remotely mirrored to Volume C at a secondary location, via Metro Mirror. This allows you to have a consistent copy of your data at both locations.
For[newly ordered 242x models], you get all the features above, plus the following additional support:
- Full Disk Encryption (FDE)
IBM was the first in the industry to deliver tape-drive encryption, so it makes sense that IBM is also the first in the industry to deliver disk-drive encryption. These are 15K rpm drives in standard 146GB, 300GB and 450GB capacities. As with tape, encrypting at the disk device eliminates the huge overhead from server-based encryption methods.
- Solid State Drive (SSD)
You can also have Solid State Disk drives in your DS8000, in 73GB and 146GB capacities, protected by RAID-5.If you are wondering what data to put on these much-faster drives, IBM has taken the work and worry out by havingintelligence in DB2 to optimize what gets placed on SSD to get the most performance improvement.
- IBM System Storage XIV
Continuing the incredible marketplace excitement over its Cloud-Opimized Storage[XIV series], IBM now has announced[new capacity options]. The IBM XIV R2 that we announced last August 2008 was a fixed 15 module configuration. In thenew configurations, you can start with as little as six modules, representing a 40% partial rack of the originalfull model. Here is a table that shows the details:
|Total Modules|| 6 || 9 || 10 || 11 || 12 || 13 ||14 || 15|
| Useable Capacity (TB) ||27 || 43 || 50 || 54 || 61 || 66 || 73 || 79|
|Interface Modules ||3 || 6 || 6 || 6 || 6 || 6 || 6 || 6|
|Data Modules ||3 || 3 || 4 || 5 || 6 || 7 || 8 || 9|
|Disk Drives ||72 || 108 || 120 || 132 || 144 || 156 || 168 || 180|
|Fibre Channel Ports ||8 || 16 || 16 || 20 || 20 || 24 || 24 || 24|
|iSCSI Ports ||0 || 4 || 4 || 6 || 6 || 6 || 6 || 6|
|Cache Memory (GB) ||48 || 72 || 80 || 88 || 96 || 104 || 112 || 120|
- IBM System Storage N series
And last, but not least, we have two new models in IBM's[N6000 series].The [N6060]has model A12 (single controller) and model A22 (dual controller). These are disk-less controllers thatyou can configure in either appliance mode or gateway mode. In appliance mode, you can attachdisk drawers such as the EXN1000, EXN2000 or EXN4000. In gateway mode, you attach external disk systems, suchas the IBM DS8000 or XIV above.
Also, IBM introduces the new [2101 model N42 rack], which has the following features:
- It's ruggedized to handle earthquakes. IBM brings a feature that we've had for a while on other disk systems to the N series with a collection of bolts and anchors to secure the rack from physical tremors.
- It's instrumented for IBM Active Energy Manager, a component of IBM Systems Director. New iPDUs are designed to help measure and monitor energy management components. As companies get more concerned about thefate of the planet, monitoring energy consumption can help reduce carbon footprint.
I'll cover the rest of the announcements tomorrow!
