fixed

The IBM(r) Power(r) S824 (8286-42A) server is a powerful 2-socket server that ships with up to 24 activated cores and I/O configuration flexibility to meet today's growth and tomorrow's processing needs. The server features:

The following fully activated IBM POWER8(tm) dual-chip module (DCM) processor configurations in a 4U rack-mount form factor:
6-core or 12-core 3.89 GHz
8-core or 16-core 4.15 GHz
24-core 3.52 GHz
High-performance 1600 Mbps DDR3 ECC memory
16 GB (#EM8B), 32 GB (#EM8C), or 64 GB (#EM8D) memory features
Up to 1 TB memory with two Power Systems(tm) processor DCMs
Up to 512 GB memory with one Power Systems processor DCM
Choice of storage features:
Twelve SFF-3 Bays/DVD Bay
Eighteen SFF-3 Bays/ eight 1.8-inch SSD bays/DVD Bay/Dual IOA with Write Cache
Split feature to 6+6 SFF-3 Bays: Add a second SAS Controller
Hot-swap PCIe Gen 3 Slots
Integrated:
Service processor
EnergyScale(tm) technology
Hot-swap and redundant cooling
Four USB 3.0 ports for general use
Two USB 2.0 ports for non-general use
Two HMC 1GbE RJ45 ports
One system port with RJ45 connector
Four hot plug, redundant power supplies
19-inch rack-mount hardware (4U)

The Power S824 server (8286-42A) supports two processor sockets, offering 6-core or 12-core 3.89 GHz, 8-core or 16-core 4.15 GHz, or 24-core 3.52 GHz configurations in a 19-inch rack-mount, 4U (EIA units) drawer configuration. All the cores are active.

The Power S824 server supports a maximum of 16 DDR3 CDIMM slots. Memory supported are 16 GB, 32 GB, and 64 GB and run at speeds of 1600 Mbps, allowing for a maximum system memory of 1024 GB.

Rich I/O options in the system unit include:
Four PCIe G3 x16 full-height, full-length slots (one CAPI controller per socket at direct PCIe x16 slot from each socket)
Six PCIe G3 x8 full-height, half-length slots (1 of 4 PCIe G3 x8 LP slots will not be available if the high-function RAID controller installed.)
Eighteen 2.5-in. HDD SFF bays and eight 1.8-in. SSDs
RAID 0, 5, 6, 10, 5T2, 6T2, and 10T2 support
One DVD
One PCIe G3 x8 slot for 1GbE 4-port LAN controller integrated
Two front and two rear USB 3.0 ports; one rear system port
Service processor
2+2 Redundant hot-swap ac power supplies in each enclosure
19-inch rack-mount 4U configuration
PowerVM(r)
Red Hat Enterprise Linux (RHEL) 6.5, or later; SUSE Linux Enterprise Server (SLES) 11 Service Pack 3, or later; AIX 6.1, 7.1, or later; or IBM i 7.1, 7.2, or later, operating system support

Not sure I would say Better but it comparable. Yes it can drive the
EXP24S in addition to the CEC DAD.


I will say better. It is more like the new feature EJ0L adapter than the feature 5913/ESA3 adapter.

- CEC is 7.2GB of compressed write cache
- EJOL is 12GB of compressed write cache
- 5913 is 1.8GB of uncompressed write cache

- CEC can support in excess of 30 SSDs but truly take advantage of 18 SSDs "with ease".
- EJ0L can support up to 48 SSDs but take advantage of 24 "with ease"
- 5913 can support up to 12 SSDs but take advantage of 12 "with ease"

When I say "with ease", it means for the OLTP DB2 based workloads used by the development lab to study the I/O characteristics of the adapters and SSDs.
